Solution to the Arsenic Problem in West Bengal: Exploring Some Non-Conventional Ways
Abstract: Some districts of West Bengal have severe arsenic contamination of soil and groundwater. The clinical manifestations of arsenic toxicity include severe skin lesions; diseases of respiratory, cardiovascular, excretory system, hepatological, haematological and neurological disorders; and even death. We have isolated arsenic-resistant bacteria which have the adaptability to survive in high arsenic concentration, accumulate arsenic and convert it to its less toxic form. Therefore, we propose bioremediation as a cost-effective and …
