STUDY OF ARSENIC USING SUBSTANCE FLOW ANALYSIS

Abstract

In this study, MFA/SFA methodology is used to form a model showing the link between different flows and processes which used to calculate the values of arsenic in different flows and processes with the help of freeware STAN. Different sources of arsenic are studied to find the relation between these sources and the other processes, change in form and accumulation of arsenic. The import, export and stock of arsenic in India is calculated, having values of 32.13 thousand ton, 11.80 thousand ton and 20.32 thousand ton per year respectively. Major sources of arsenic in India are found to be irrigation water and mining of mineral ores. Accumulation of arsenic is seen in the soil and water bodies which may require preventive measures. The formation of stock in a household is the cause of worry as arsenic here comes in direct contact with the human being, therefore the preventive measure for food and supply water is necessary. The aim of this study is to provide all the necessary information to the authorities so as the can make an informed decision.
