| Abstract | ||||
| Insecticides are used to control diseases spread by arthropods, but theys vary greatly in toxicity. Toxicity depends on the chemical and physical properties of a substance, and may be defined as the quality of being poisonous or harmful to animals or plants. Poisons have many different modes of action, but in general cause biochemical changes which interfere with normal body functions. Toxicity can be either acute or chronic. Acute toxicity is the ability of a substance to cause harmful effects which develop rapidly following absorption, i.e. a few hours or a day. Chronic toxicity is the ability of a substance to cause adverse health effects resulting from long-term exposure to a substance. There is a great range in the toxicity of insecticides to humans. The relative hazard of an insecticide is dependent upon the toxicity of the pesticide, the dose received and the length of time exposed. A hazard can be defined as a source of danger. The great majority of insecticides are poisonous to man and his beneficial insects and animals and are carcinogenic agents particularly, the halogenated hydrocarbons containing benzene ring. | ||||
