Located in Southern Asia, bordering the Bay of Bengal, between Burma and India, lies my place of origin, Bangladesh. change magnitude at 2.09% (2005 est.), the population is around 144,319,628 of this country which is slightly littler than Iowa. Clearly, not only does it have a history as being one of the most densely populated countries in the world and with its poverty rate increasing proportionally, the unfortunate inhabitants ar facing a crisis in lack of safe alcoholism water. Many people use the term clean to call to the type of drinking water which Bangladesh lacks, but I esteem the term safe is more appropriate. The reason for this is due to the concomitant there argon advanced arsenic levels found in water. This, I find to be the most pressing environmental issue.
Arsenic is present in umteen foods that we eat and in becharm amounts this is actually essential to good human health. However, in high concentrations, arsenic can be extremely toxic. Two common forms of arsenic is As(III) and As(V), where the latter is reduced to As(III) in the human body. As(III) becomes more toxic as it builds up and by continuous transmutation of As(V). In many countries, such as Bangladesh, water pollution, especially of fishing argonas, results from the use of commercial pesticides such as Pb3(AsO4)2 and Ca3(AsO4)2, thereby containing As(V).
Health problems are specifically common when there are more natural than anthropogenic sources of arsenic. For example, groundwater contaminated by course occurring arsenic is the main source of drinking water for many Bengalis (approximately 40 million). As a matter of importance, the arsenic concentrations are greater in the Bengal Delta. This form of water is difficult to comment because arsenic is tasteless, odorless, and invisible. Its no surprise then, the World Health brass section (WHO) has named this area...
