Introduction
According to National Institute of Environmental Health Science, the contamination of sources of water like rivers, lakes, groundwater and oceans due to introduction of hazardous chemicals and other contaminants is known as water pollution.1 Leading water contaminants include pesticides and fertilizers, food processing waste and sewage, mercury, lead and other heavy metals, and chemical discharge from industrial waste.
Water Pollution is one of the serious threats to the public health and well being in Bangladesh. The sources of drinking water are degraded with the presence of pesticides, harmful metals and coliform bacteria.2 Human activities like inappropriate transfer of sewage in rivers and meaningless use of chemicals in agriculture and improper disposal of waste significantly deteriorate the quality of water sources. The microbial contamination also contributes to complex health problems in Bangladesh.
The purpose of this report is to recognize the health problems that develop the need of law reforms for improving the health outcomes in Bangladesh, (a) to analyze the existing legal framework that can be applied to health issues; (b) to identify the institutional and legal framework to be deployed in process of advocacy for reforms; (c) to discuss how these frameworks are applicable to the health problems; (d) to identify the potential shortcomings; and (e) to recommend strategies to prevent the shortcomings.
Identifying the Health Problems
Majority of the population in Bangladesh uses groundwater and surface water having significantly increased levels of arsenic. Therefore, there is high health risk related to water consumption. Bangladesh has high rate of childhood mortality due to contaminated water. The diseases like cholera, hepatitis A, dysentery and diarrhea are directly associated to unhygienic potable water. 97% of the overall population in rural locations in Bangladesh take drinking water from tube wells thus more than 77 million people are exposed to high levels of Arsenic which is a carcinogenic element.2 Excessive exposure to arsenic increases the risk of diseases like renal cancer, skin cancer and lung cancer, while also giving rise to generation of “arsenic orphans”.2 9.5% of the annual deaths in Bangladesh occur due to lack of hygiene, sanitation and water related reasons.3
The trace elements like Cu, Cr, Fe, Ni, Zn, Pb, Cd and Mn when present in water in limited concentration are considered essential for the human health.3 However, in Bangladesh Rivers their concentration mostly exceeds the limit directed by WHO. The water contains excessive amounts of many cations and anions. Alterations of Sodium ion in human body may adversely affect the plasma fluid volume, osmotic pressure, acid base balance, blood pressure and electrical activity of the cells in body. Excessive intake of Potassium ion may cause hyperkalaemia, resulting into cardiac arrhythmias. High consumption of calcium results into side effects like hypercalciuria, calcification of soft tissues, calculi in urinary tract and hypercalcemia.
Bacterial contamination due to Enterobacter, Enterococcus, Aeromonas, Klebsiella species, E.coli, Pseudomonas, Salmonella, Listeria, Shigella, Staphylococcus and Vibrio species is highly significant in Bangladesh water bodies. As a result, there is extremely high incidence of diseases like cholera, food poisoning, skin lesions, typhoid, diarrhea, UTI and gastroenteritis.5
Current Legal Framework
Bangladesh has enacted legislative framework to safeguard the ground resources of water from pollution. Article 31 and 32 of constitution direct the fundamental right to life.4 Through Bangladesh Environment Conservation Act 1995, the government revised most of the old legislations. However, there are problems in effective implementation due to lack of institutional and political will. There are legislations to protect the inland water resources from pollution like Water Act 2013, National Environment Policy (NEP), The Water Resource Planning Act 1992, Territorial Water and Maritime Zones Act 1974, The Agricultural Pests Ordinance 1962, Bangladesh Environment Conservation Act 1995, Environment Conservation Rules 1997, Environment Court Act 2010, Water Supply and Sewage Authority Act 1996, Local Government Laws, National River Protection Commission Act 2013, Water Rule 2013, Ground water Management Act 2018 and Pesticides Act 2018.4
The Article 18A of the constitution...
