Insecticides are the pesticides used against insects. Organochlorines are class of synthetic organic insecticides .  Organochlorines are chlorinated hydrocarbons and contains the elements carbon and chlorine. They have been used extensively from the 1940s through the 1960s. Bioaccumulation They break down slowly in the environment and accumulate in the fatty tissues of animals and they stay in the environment and food web long after the being applied (Bioaccumulation).   OCs in Food Chain They have long chemical half-life (7-30 years), which makes them highly persistent. So, most people have organochlorine pesticides present in their bodies.  It cause reproductive failure among birds.  Organochlorine are persistent organic pollutants (POPs) . They act primarily by altering the movement of ions across the nerve cell membranes, thus changing the ability of the nerve to fire and interfere Na + and K + ion permeation. Examples 1. DDT  First commercially produced in...

An insecticide is a pesticide used against insects. They include ovicides , larvicides and adulticides used against the eggs , larvae and adults of insects, respectively. The use of insecticides has been very popular since the arrival of first synthetic chemical insecticides during the days of world war 2.  Insecticides cartoon Since then, the scientists have been working on to increase the insecticidal potential and reduce the toxicity of the insecticides. We will be discussing more about these issue later on, first of all, lets have a look at the common types insecticides. Types of Insecticides 1. Systemic Insecticides  2. Contact Insecticides  3. Natural Insecticides  4. Plant-Incorporated Protectants (PIPs)  5. Inorganic Insecticides  6. Organic Insecticides Synthetic Organic Insecticides The synthetic organic insecticides are relatively new compounds. The first synthetic organic insecticide DDT was synthesized in 1874, and its insecticidal pr...
