Carbamates insecticides act by a similar mechanism to organophosphate pesticides, but have a shorter duration of action. They are widely used, and have varying degrees of toxicity. Like organophosphate pesticides, they interfere with the conduction of signals in the nervous system of insects, and in cases of poisoning with high levels of exposure, humans. Information on the health effects of carbamate pesticides as a class, and specific carbamate insecticides, can be found by clicking on the appropriate links below. CDC's biomonitoring results for carbamates are available at http://www.cdc.gov/exposurereport/pesticides/carbamate/default.htm.
