Impact of Sewage and Tannery Effluents on Agriculture

Abstract

   Environmental pollution is one of the major problems of the world and it is increasing day to day due to urbanization and industrialization. Tannery effluent is one of the major pollutants that is affecting our environment in present times and has a strong potential to cause soil and water pollution owing to the discharge of untreated effluent. It uses more than 250 chemicals for leather production and release a complex mixture of toxic organic chlorinated phenols, toxic Cr(VI), and other toxic pollutants such as sulphides, Cadmium and phenolic compounds, magnesium, potassium, sodium, cadmium compounds, cobalt, copper, antimony, barium, selenium, mercury, zinc, arsenic, PCB, nickel, formaldehyde resins, pesticides residues, mineral salts, dyes and solvents like grease and oils. Cr(VI) and chlorinated phenols are the basic prominent sewage toxic to biota and humans as well as other environments or ecosystems. The present study deals with the effects of sewage and tannery effluents on various types of crops in India.
