Arsenic Toxicity: Challenges and Solutions

Abstract

Arsenic poisoning has become a global problem in the recent times. It is estimated that >300 million population are exposed to arsenic worldwide. Bihar is the state in India, which is in the vicinity of river Ganges where seven major tributaries from Great Himalayas through Nepal meet river Ganges. This entire Gangetic plain area is highly fertile land, with very high population density. In this state an estimated 10 million people are exposed to arsenic contaminated drinking water as well as irrigation water. Groundwater is the primary source of arsenic poisoning which has caused serious health hazards to the exposed population. The exposed population are exhibiting typical symptoms of arsenicosis such as hyperkeratosis, melanosis, pigmentations and other skin manifestations. Apart from this they are also exhibiting other symptoms such as disorders of liver, kidney, nervous system, cardiovascular, hormonal, etc. The prolonged arsenic exposure also leads to different types of cancer. The cancer among the exposed population is of skin, liver kidney, gall bladder, bladder, breast, colorectal, etc. Hence, it is very important to evaluate the health problems exhibited in the exposed population. The present study highlights the health problems of the exposed population of different parts of Bihar with confirm presence of elevated arsenic concentration in groundwater (>10 μg/L). Apart from this the study also examined the mitigation strategies undertaken by the state Government for the exposed population.
