EVALUATION OF IMPACT OF PESTICIDES ON THE BASIS OF THEIR PHYSICO-CHEMICAL PROPERTIES
The term pesticide covers a wide range of compounds including insecticides, fungicides, herbicides, rodenticides, molluscicides, nematicides, plant growth regulators and others. When a pesticide is used in the environment, it becomes distributed among four major compartments: water, air, soil and biota. The fraction of chemical that will move into each compartment is governed by the physico-chemical properties of that chemical. To understand how pesticides move in the environment, one must first understand certain physical and chemical characteristics of pesticides, as well as how these characteristics determine a pesticide's interaction with the environment. This article throws light on impact of pesticides in environment on the basis of physicochemical properties so as to understand the underlying basis of their distribution in non target life.
