A complete set of data is needed for the toxicological and ecotoxicological evaluation of pesticides. 4 Routes of indirect exposure to pesticides. 2007 6:33am Compositor Name: JGanesan Pesticides: Classiﬁcation and Properties 33 Regarding the human health assessment, toxicological studies need to include the following tests: A: Acute toxicity, which involves harmful effects in an organism through a single or short-term exposure, should be studied by: 1. Dermal toxicity test: Rabbits are employed more often than any other species for studies of skin toxicity, although guinea pigs, rats, or mice are also used.
Risk characterization is the estimation of the incidence and severity of the adverse effects likely to occur in a human population, animals, or environmental compartments due to actual or predicted exposure to any active substance. Humans can be exposed to pesticides by direct or indirect means. Direct or primary exposure normally occurs during the application of these compounds and indirect or secondary exposure can take place through the environment or the ingestion of food. 4 summarizes the main routes of indirect exposure to pesticides.
These compounds have a broad spectrum insecticide and have been used for the control of insect pests of fruits, vegetables, and cotton as soil insecticides and for seed treatment. 15). 4 ORGANOPHOSPHORUS Organophosphorus insecticides are hydrocarbon compounds which contain one or more phosphorus atoms in their molecule. They are relatively short lived in biological systems.
