Chronic toxicity pyrethroids

Day, K. and N.K. Kaushik. 1987a. An assessment of the chronic toxicity of the synthetic pyrethroid, fenvalerate, to Daphnia galeata mendotae, using life tables. Environ. Pollut. 44 13-26. 

There are literally thousands of chemicals and/or formulations in the major categories (i.e., insecticides, herbicides, fungicides, roden-ticides, fumigants, nematocides) of pesticides. Therefore, no attempt was made to provide a review of representatives of all the major classes of pesticides. In the section which follows, selected pesticides from three chemical classes, the organophosphates, the halogenated hydrocarbons, and the pyrethroids, will be discussed in regard to the differences and similarities between acute and chronic toxicity. The criteria for selection of the examples are mainly related to the availability of current information in the literature. 

The Office of Pesticide Programs (OPP), EPA, Washington, DC, has a complete file on the acute and chronic toxicity of the registered pyrethroids. Information on...
