A Review on Detection of Arsenic in Water
For years, various methodologies to detect harmful content in water and the environment have been proposed. Arsenic is a naturally occurring element which is a contaminant as it is poisonous and carcinogenic. Humans are routinely exposed to arsenic through ingestion or contact with arsenic containing soil. Arsenic is found in two forms namely organic and inorganic. Inorganic arsenic is classified into two types namely As(III) and As(V). Industry also contributes to arsenic pollution in water. According to a survey, the largest reported population exposed to naturally occurring inorganic arsenic was found in West Bengal, India and neighbouring Bangladesh.
