Water Pollution in Bangladesh Essay Example

Water Pollution in Bangladesh Paper Water is the most vital element among the natural resources, and is crucial for the survival of all living organisms. The environment, economic growth and development of Bangladesh are all highly influenced by water its regional and seasonal availability, and the quality of surface and groundwater. Spatial and seasonal availability of surface and groundwater is highly responsive to the monsoon climate and physiographic of the country. Availability also depends on upstream withdrawal for consumptive and nonconsecutive uses. In terms of quality, the surface water of the country is unprotected from untreated industrial effluents and municipal wastewater, runoff pollution from chemical fertilizers and pesticides, and Oil and lube spillage in the coastal area from the operation of sea and river ports. Bangladesh is the lower riparian of three major river systems, the Ganges- Pad, the Paramount-Jejuna and the Meghan. The aquatic environment for living organisms can be affected and fasciculation of harmful substances in the water-dependent food chain can occur. A variation of inland surface water quality is noticed due to seasonal variation of river flow, operation foundational units and use of agrochemicals. Overall, inland surface water quality in the monsoon season is within tolerable limit with respect to the standard set by the Department of Environment (DoE).

The underlying driving forces for this are poverty, an unhealthy national economy, lack of institutional strength, and lack of awareness and education. Pollutants that enter the marine and coastal environment originate on land in the form of runoff from municipal, industrial and agricultural wastes, and from commercial seafaring activities. Industrial effluent In Bangladesh, industrial units are mostly located along the banks of the rivers. There are obvious reasons for this such as provision of transportation for incoming raw materials and outgoing finished products. Unfortunately as a consequence, industrial units drain effluents directly into the rivers without any consideration of the environmental degradation. Region, which comprises bout 49 per cent of the total sector. Inorganic pollutants are mostly metallic salts, and basic and acidic compounds. These inorganic components undergo different chemical and biochemical interactions in the river system, and deteriorate water quality. The most problematic industries for the water sector are textiles, tanneries, pulp and paper mills, fertilizer, industrial chemical production and refineries. A complex mixture of hazardous chemicals, both organic and inorganic, is discharged into the water bodies from all these industries usually without treatment. The highest numbers of industrial establishments in the country are located in the North Central (NC) WATER POLLUTION AND SCARCITY Inland Surface Water Pollution The overall inland surface water quality in the monsoon season is within tolerable limits, with few exceptions, including the rivers Brigands, Ball, Statistical, Grappling, and Rupees. However, concerns over surface water quality are gradually emerging due to the dispersed locations of polluting industries, and the adverse effect on surrounding land and aquatic ecosystems, as well as subsequent impacts on the livelihood system of the local community. The extreme examples of this type of effect are near Dacha at Cinnabar and Saver, where industrial effluents are discharged into nearby land and water bodies without any treatment. Among the polluted areas, the Worst problems are in the River Brigands situated to the south of Dacha, where the most significant source of pollution appears to be from tanneries in the Hazarding area. In the dry season, the dissolved oxygen level becomes very low or non-existent and the river becomes toxic (WARP, AAA). Water quality data at TV0 stations of the river Brigands in 1 998, Hazarding and Chad night, showed that DO and BODY exceeded the tolerable limits in the months of January, February, March and December, with the worst situation prevailing in the months of January and February The seasonal variation of water quality in the Brigands is linked with seasonal variation of water flow and the operation of tanneries. Source: Department of Environment, 2000) Groundwater pollution Groundwater has different uses, but the standard for its quality was set nationally. Groundwater was treated as the best source of safe drinking water, before arsenic contamination was reported. However, 54 per cent of hand pumped tubeless were found to have fecal contamination, due to poor wellhead design, faulty construction and management, but the aquifers themselves were not polluted (Hogue, 1998). Source: SWAM Arsenic High levels of arsenic in groundwater can cause serious human health problems if imbibed for a long time (from 5 to 15 years); including skin ailments, damage to internal organs, skin and lung cancers, and eventual death. The recent major studies carried out on arsenic reveal that among 30,000 tubeless studied, 2,000 of them exceeded the national standard Of . 5 MGM/l for drinking purposes (the WHO guideline is 0. 01 MGM/l). The problem is acute in tubeless abstracting groundwater from 10 m to 1 00 m depths in the Southeast, South Central (the northern part only), and Southwest regions. To a lesser extent, the eastern part of the Northeast region, and the very southern fringe of the North Central and Northwest along the river Ganges are affected. The most seriously affected districts are Chandler, and those around it. It was estimated that more than 20 million people drink water exceeding the national standard for arsenic levels. The resent of arsenic is a naturally occurring phenomenon, but prolonged use of the water can be very harmful when the levels cross the standard limit. Contrary to earlier reports by the press, the available evidence strongly argues against the idea that arsenic contamination originates either from the use of synthetic chemicals, such as wood preservatives, or insecticides. Arsenic contamination has considerably serious implications for groundwater abstraction in affected areas. This impinges on domestic water supply, since groundwater is the preferred source, because compared to surface water it is sees likely to be focally polluted. Already thousands of cases of arsenic poisoning have been recorded among local people, and some deaths have been reported. Clinical studies are being carried Out by the Dacha Community Hospital. In agriculture, there are also serious implications from the possible transfer of arsenic into the food chain through crops that are under irrigation with arsenic-contaminated water, and then consumed by humans. There is little evidence of arsenic contamination in rice grains through irrigation with arsenic contaminated water. However, boiling rice in arsenic-affected water goes lead to its contamination, which causes serious problems. The crops most likely to absorb arsenic from irrigation are leafy vegetables, and possibly coconuts, and melons. These crops pass arsenic into the food chain. The effects of arsenic on pond-reared fishes are now under study. Livestock that drinks arsenic-contaminated water should also be under study, because humans consume these animals and their products. The infiltration Of arsenic-affected water in the soil also needs to be studied, along with possibility of infiltration into shallow aquifers. Source: WARP, Bibb CONCLUSION Water resources need to be managed both qualitatively and quantitatively due to their importance for economic development, and the physical and social environments. Particularly in Bangladesh, where water is intricately linked with the lives of people and economy, its value has increased with competing demand. Therefore, economic efficiency of water use is a major policy consideration. Frequent floods and droughts in Bangladesh impose tremendous variability, and make it difficult to manage development based on prices and the market mechanism. The Government of Bangladesh is acing a number Of growing problems, because it cannot address water sills_Jess in a comprehensive manner. Separate ministries and departments are in charge of pollution control, surface irrigation, groundwater irrigation, fisheries, public health, environment, municipal water supply, power and navigation, and each acting independently.

Effects of Cime essays

Effects of Cime essays Crime affects people in several ways: although law enforcement authorities have made numerous efforts to reduce and prevent crime, it still follows an increasing trend in some communities. Some of the ways crime has affected people are the emotional turmoil that victims of crime go through, the stereotypical labeling of a group or race of people as criminals and how it affects where people choose to live. Crime victims suffer in several ways when crime occurs. Victims of crime suffer emotionally, financially and sometimes physically. In the United States, Americans are known to commit most crimes; but on September 11 2001, people from different countries planned and committed a serious and unforgettable crime against Americans. On that dreadful morning, everything looked and felt like any other day until suddenly a group of evil doers, as President Bush calls them, decided to fly planes fully filled with highly inflammable gas into the world trade center, the Pentagon and a field in Pennsylvania. A perfect example of what crime victims go through is the impact that this attack had on Americans. About 5000 people died due to this senseless act of crime. People with or without immediate family members and friends amongst the dead and injured were emotionally devastated. A sizable amount of job positions were lost in the hospitality business, the airline business and businesses in the immediate vicinity of the crash sites. This criminal act has also resulted in an ongoing war in poverty stricken Afghanistan. Crime also affects peoples opinion and judgment of people from other racial backgrounds. Some people, especially victims of crime tend to label all people from that particular race who committed the crime as potential criminals. This usually occurs when for instance a black person commits a crime and for that reason, any other subsequent crimes are attributed to black people. Whe ...

Unit 6 PP mini - Coursework Example Diversity is very critical when it comes to the aspect of a high-performance team. An effective team has to have members who have a widespread range of experiences and skills from which to draw for guidance, motivation and support (Melton, 2008). In reference to the birthday planning project, diversity is necessary since the party involves many activities such as decoration, cleaning of the environment, invitation, and purchase of requirements. The team members have to have particular weaknesses and strengths that complement each other. Another example, where diversity is necessary, is during the actual party where each team member is expected to play his/her role for the team to run smoothly. A high-performance team rely on effective communication so as to pool their work efforts (Rad & Levin, 2003). Additionally, there should be effective written and oral communication that is concise and clear. It is also important for each team member to feel contented and able to speak out about his/her given responsibilities making effective communication is vital to the birthday party project. Effective communication allows the team member to provide their creative ideas on the topic, and this is very important for the birthday party. A team member may add an idea, for instance, towards the decoration of the party. Clear goals and expectations drive a high-performance team. Having a team working toward the same objective and should be undoubtedly understood by all the team members (Melton, 2008). Additionally, each team members has to know their responsibilities clearly in the project. In reference to the birthday party project, all the team members should be mindful that the end goal is to create the best birthday party without any setbacks. The team members also have to know their responsibilities properly and take them seriously so as to achieve the end goal. Lastly, members of a high-performance team have to trust each other in

Effects of various types of drugs Research Paper

Effects of various types of drugs - Research Paper Example This essay considers the various types of effects of these drugs as they influence the person or persons who have consumed them. Depressants have are a specific type of psychoactive drug that temporarily limits the functionality of a specific part of the brain or body ("Msds glossary," 2010). There are a broad variety of depressants, many of which human beings consume recreationaly. In these regards, one of the most popularly consumed depressants is alcohol. While most individuals have experienced the effects of alcohol, its necessary to advance an objective understanding of these effects as they relate to different types of psychoactive drugs. Some of the most notable effects of alcohol are disinhibitions. In these regards, the impulses one might think or feel when they are sober but are inhibited to act upon – when under the influence of alcohol – the individual is then considerably more likely to follow through (Myers 2010). Another notable effect of alcohol is slowed neural response. In these regards, significant alcohol consumption slows the users sympathetic nervous system so they oftentim es exhibit effects such as slurred speech, and impaired movement. The slowing of the individuals neural response through alcohol consumption is a highly notable effect, as it is through this effect that individuals oftentimes become involved in fatal traffic accidents. Another highly prominent type of depressant are barbiturates. Barbiturates are understood as, â€Å"can be used as hypnotics, sedatives, anticonvulsants and anesthetics, although they are probably most familiar as sleeping pills ("Barbiturate,"). In these regards, barbiturates are generally understood as tranquilizers for their sedative effects. While in small doses barbiturates have been administered as sleep or pain aids, in larger doses they can be potentially dangerous, leading to impairment of memory,

The Issues Of Fresh Water In Singapore Environmental Sciences Essay

The Issues Of Fresh Water In Singapore Environmental Sciences Essay Singapore is an island and urban city state with no rural hinterland and hence, it has been depending on Malaysia for nearly forty percent or more of its water supply. However, Singapore is not short of fresh water as it receives an average of around 2,400 mm of rainfall annually. The only constraint faced by the country is capturing and storing as much of this rainfall as possible, on limited amounts of land areas, so as to achieve self-efficiency in water issues. Recycling efforts in Singapore started in 1966 when the Jurong Industrial Water Treatment Plant was commissioned to supply industrial water to the Jurong Industrial Estate (JIE). This water comes from treated sewerage effluent and is meant for industrial use in the Jurong area as well as by several oil refineries. The Singapore government encourages industry and private enterprises to recycle water. Also, tax rebates have been provided for factories that install water-saving plants. Bottles of NEWater Singapore has also developed NEWater, a three-stage process which brings waste-water to a quality that is better than that produced by the Public Utilities Board (PUB). Treatment begins with Microfiltration to remove suspended solids, colloidal particles, bacteria and viruses. The next process is Reverse Osmosis, which involves applying of pressure for water to flow from the concentrated side to the less concentrated side through a semi-permeable membrane to remove inorganics like heavy metals, such as nitrate, chloride, sulphate etc. The third process, Ultra-violet disinfection, is a safety back-up to remove any bacteria or viruses that cannot be removed by Reserve Osmosis. Desalination is a process of removing excess salt from water (eg. seawater) to enable it for drinking purposes. It has been used to augment water for some time, but it was not adopted as a matter of policy until recent years. This method is considered successful, as this source of supply produce 12% of Singapores daily water needs. Although desalination costs under current improved technology are higher than traditional means of treatment, Singapore has decided to go ahead in the belief that new technologies will reduce the costs further. 3. Impoundments and reservoirs Singapore has several impounding reservoirs inland including Seletar, Peirce and MacRitchie etc. To increase storage capacity, seven reservoirs have been developed by damming the river mouths. It was in that context that a plan to maximise collection of surface resources by extending the present 24.3 square miles of collection grounds to 156 square miles (about 75% of the islands total area) was proposed. However, geological conditions limited the availability of groundwater, hence the plan focused on retrieval of stormwater and water recycling instead. Another reservoir which was built in the recent years was Marina Barrage, which was officially opened on 30th October 2008. Marina Barrage is a dam built across the Marina Channel. Water flows into the reservoir from some of Singapores most well-known waterways, including the Singapore River, Stamford Canal, Rochor Canal, Geylang River and the countrys longest river, Kallang River. Marina Barrage was envisioned by Prime Minister Lee Kuan Yew in 1987, after the great clean-up of the Singapore and Kallang Rivers. Building the barrage on the soft sea bed amidst changing currents and constantly moving marine traffic was a major challenge. From the air, the pump house of the barrage looks like that number 9, which signifies longevity in Chinese. This major engineering achievement is symbolic of Singapores development as a City of Gardens and Water. How Marina Barrage works? The Barrage acts as a physical barrier to separate the reservoir from the sea. The steel crest gates of the Barrage will act as a tidal barrier to keep the high tides out. Under normal conditions, the crest gates will remain in an upright position to isolate the reservoir from the sea. During heavy rains that collide with low tide, the steel crest will be lowered to release excess storm water into the sea. During heavy rains that collide with high tide, the steel crest gates remain erect, hence storm water cannot flow out to sea naturally. Instead, large drainage pumps will be operated to pump water out to sea. With the Barrage in place, the pockets of low-lying areas in the city will no longer be prone to flooding. 4. Stormwater run-off Harnessing stormwater at minimum cost requires proper land-use planning and pollution control to ensure that stormwater run-off can be efficiently collected and that pollution levels are low. Stormwater harvesting from urban land was consistent with the overall policy of land use in this land-scarce republic, in which land was seen as too valuable for its use to be restricted to a single purpose such as for housing. In the words of the Minister for National Development: If we designate more land for water catchments, there will be less land for housing and other developments. The reverse is also true. Optimising and maximising the use of land and water helped the country to overcome constraints to a certain extent. (Adapted from: The Straits Times,1996) Singapore was the first country in South-East Asia (SEA) to develop viable stormwater run-off schemes. Among the various schemes, the Bedok and Lower Seletar Schemes are the largest. Surface water for these schemes comes mainly from the housing estates and new towns of Ang Mo Kio, Bedok, Tampines and Yishun and the area near Changi International Airport. Water is conveyed to the storage reservoirs of Bedok and Lower Seletar. One important feature of this scheme is the emphasis on close co-ordination between several agencies, such as the Housing Board Development (HDB), the Ministry of the Environment (ENV) and the Planning Department, in order to ensure that water collected from urban surfaces is low in pollutants. In addition, the drainage system designed in such a way that it channels water through concrete channels to suitable collection ponds situated at topographic low points. An automatic monitoring system ensures that only discharges produced by heavy storms resulting in run-o ff above a certain volume are collected. One example of the innovative approach to stormwater collection is making use of the empty space under the interchange of the Seletar and Bukit Timah expressways for a water collection pond. 5. Conservation of water In addition to developing and diversifying water resources, water conservation is also key to ensuring a sustainable water supply. Through our various water conservation initiatives, Singapore has managed to reduce domestic water consumption from 172 litres per capita per day in 1995 to 157 litres in 2007.(Adapted from Conserve, Values and Enjoy by Ministry of Environment and Water Resources, 08 July 2008) It is a difficult task to keep looking for new sources of water, but the situation can be improved if we can control our ever-increasing demand of water. To provide water for all, PUB calls on all Singaporean to play our part in water conservation and to keep our water catchments and waterways clean so that we can enjoy our water resources. One way to discourage excessive use of water is to impose water conservation tax on the amount of water used. This additional tax is added to the price of the water consumed by households and varies according to the amount of water they use. A household that consumes more water will pay higher taxes compared to household that used less water. Additionally, there are varieties of activities organised to teach Singaporeans to view water as a scarce and precious resource, and to use it wisely. Water conservation talks are conducted in schools and leaflets on water conservation are distributed to households. Water-rationing exercises, where the supply of water to some homes is temporarily cut off, are also carried out in housing estates. Effectiveness of the solutions implemented by government So far, Singapore has been able to tackle the problem of a limited supply of fresh water with the introduction of water reclamation, desalination of sea water and impoundments. Technological innovations in modern society have enabled us to have larger catchment areas, to build dams and to obtain fresh water from sea water and used water. Policies aimed at water conservation have also produced certain positive results. Based on the research conducted by the Ministry of the Environment and Water Resources, the domestic water use per person has generally fallen between 1995 and 2007, from 172 litres per day to 157 litres per day. This means that Singaporeans are more aware of the challenge they are to face nowadays. Introduction of water conservation taxes and activities about water conservation also help to spread awareness about the importance of water conservation. Recommendations regarding the current policies from our committee Government can introduce fine of a certain amount of money for over-usage of water. This means that if the households use unusually large amount of water every months, the government could send down the letters to inform them that they have used too much water compared with the national average, and they should manage their usage well from now on or the authority would have to take action in order to save water. In case if the household owners do not take mind of the warnings, they would be fined. Similarly, households have done well in controlling the water usages should be rewards for their effort put in. For example, tax-relief can be introduced to residents who use water-saving devices at home. Measures like this can encourage the people to install water-saving devices in their houses, hence the overall usage of water would gradually drop to an acceptable level, and the people can be satisfied with rewards given by government for their well-being as the citizens. Examples of water-saving devices: Shower head Water-saving tap Toilet stop Such water-saving devices help reduces water usage at our homes. We uses 9 litres of water whenever we flush the toilet. A toilet stop can be used to cut down the usage of 9 litres. It is added to the toilet flushing mechanism to stop the flushing when the handle is released. Thus if used wisely it allows people to save up to 20% of their total water bill.

Nursing Laws and Ethics

As nursing profession continuously progresses in its quest for excellence, its nature becomes complex in the light of meeting the standards set forth by the implementing bodies in nursing profession. These standards are indeed the result of careful assessment and observation made to resolve the never ending issues and concerns pertaining to the legal responsibilities and ethical obligations of nurses.Many of these include the duty to interpret and carry out orders, duty to monitor the patient, delegation of authority, consent to medical and surgical procedures, confidentiality of medical records, negligence and others. But among the issues and concerns aforementioned, one of the most controversial issues which caught my attention is â€Å"Malpractice†. Sometimes, nurses, for some personal reason, go beyond their boundaries and exceed the scope of nursing practice they are ought to observe at all times.In abroad, there have been numerous reported incidents wherein Filipino nurs es who happened to be medical doctors here in the Philippines were charged of malpractice and was deported back here for attempting to save a dying patient in the absence of the medical doctor in-charge. Legally speaking, what they did was a â€Å"breach of duty† and basically, they should have been subjected to corresponding sanction.However, as far as nurses’ sworn duty is concerned, it’s also their responsibility to save and protect life at all cost. I understand that, doing the job beyond their legal limitations was hard for them. But because Filipino nurses are typically compassionate, they have set aside the thought of facing consequences of their actions and didn’t think twice when they saw the imminent danger to the patient’s life, considering their knowledge and experience in critical situations as doctors.It is quite paradoxical in nature, to which side they are to choose in the midst of ethical dilemmas like that. In the code of nurses d eveloped by the American Nurses Association, there is no way they condone ethically passive behaviour. But being passive will mean two things at the same time. First, being passive and adherent to the scope of their jobs will mean being firm in their chosen profession and avoid legal responsibilities on their part.Secondly, it will mean depriving them of their own wisdom and freewill to do the right thing and do nothing as if they can’t do anything in the midst of life-threatening situation. As for me, we are all trained and equipped with ethical principles and laws just to guide us in making the right decision for the good of all. But no one can really tell us what exactly to do or which way to go. It is always, our wisdom, wise thinking and judicious assessment of the situation that would lead us to make the correct decision.
