Fumes of pesticides like the DDT get biomagnified and cause disorder to kidney, brain and problems of circulatory system.  Accumulation-mode particles are more efficient per unit mass than coarse particles in causing visibility impairment. This paper deals with poly Nuclear aromatics hydrocarbons (PAH) for a period of three months from March 2014 to June 2014 in Tuticorin industrial area. The accumulation mode particle components principally responsible for visibility impairment are sulfates, nitrates, organic matter, and elemental carbon. Fumes from pesticides, fungicides, insect repellents can be carcinogenic. Soil dust, particularly in the fine tail of the coarse particle distribution, can also impair visibility. All of these particles scatter light to some degree, but, of these, elemental carbon plays the most significant role in light absorption. Since elemental carbon, which is a product of incomplete combustion from activities such as the burning of wood or diesel fuel, is a relatively small component of PM in most areas, visibility impairment is generally dominated by light scattering rather than by light absorption.
