ABSTRACT:
With enormous increase in the population the demand of pesticides gradually increases throughout the world. the question arises that where the fault begins, whether farmers are spraying overdose of pesticides either to earn money or to save their crop. Movement of pesticides into surface or ground water affected human & wildlife beyond acceptable safety levels where 20000 deaths reported annually.
INTRODUCTION
Pesticides are biocides designed to be toxic to particular groups of organism, they have considerable adverse environmental effect.pesticides have had some of their stricking effects on animals.
For example- Bees are extremely important in the pollination of crops & wild plants, and although pesticides are screened for toxicity to bees, many bees are killed by pesticides, resulting in the considerably reduced yield of crops dependent on bee pollination.
ENVIORNMENTAL EFFECTS OF PESTICIDES: Over 98% of sprayed insecticides & 95% of herbicides reach a destination other than their target species, including nontarget species such as air, water, bottom sediments and food.
EFFECTS ON HUMAN: They suspected to be carcinogens or disrupting endocrine activities, in drinking water & food. International & National regulatory agencies, reports pesticide residues in human food (imported & home products) are numerous.
- they can enter the human body through inhalation of aerosols, dust & vapors that contain pesticides; pesticides are sprayed on to food, especially fruits & vegetables, they secrete into the soils &ground water which can end up in drinking water also it can drift & pollute the air.
- the chemicals are accumulated in the body over time,exposure to pesticides can range from mild skin irritation to birth defects, tumors, genetic changes, blood & nerve disorders, endocrine disruption & even coma or death.
ELIMINATING PESTICIDES: Alternative methods to pesticides such as manually removing weeds & pest from the plants, applying heat, covering weeds with plastics and placing traps and lures to catch or move pest.
