Here is what I read about Sevin (carbaryl):
Health Effects
Acute effects of carbaryl exposure in humans includes malaise, muscle weakness, dizziness, sweating, headache, salivation, nausea, diarrhea, incoordination, slurred speech and a depression of breathing combined with excess fluid in the lungs. With high exposure the most common cause of death is the pulmonary edema, the combination of too much lung fluid and not enough air.
Chronic effects of very small doses, less than one one-thousandth of the LD0, include decreasing the kidney’s ability of adsorb amino acids, the links on protein chains, and abdominal cramping.[5] Similar doses have been shown to cause kidney abnormalities in rats and dogs,[6] reduced heart rates,[7] liver pathologies and reduced blood clotting in rats[8]. Children, pregnant women, older persons and individuals with compromised immune system are more prone to the effects of carbaryl.
Synergystic Effects
Carbaryl reacts with a striking number of other products which make its use all the more dangerous. Carbaryl reacts with many other pesticides including phenoxy herbicides like 2,4-D,[9] the wood preservative Pentachlorophenol, the anti-ulcer drug Tagamet (cimetidine),[10] and the histosomiasis drug Niridazole[11].
Effects to the Environment and Wildlife
Carbaryl has deleterious effects on a variety of wildlife including beneficial arthropods, birds, fish, earthworms, plants and bacteria.
Because it is a broad spectrum insecticide with a mode of action common to the majority of living organisms, its target insects (mites) are not the only organism killed by its use, but numerous beneficial insects. This has been found in both agricultural and non-agricultural systems.[12]
Toxicity to fish is varied but can cause death in concentrations as low as 2-16ppm in water.[13] Sublethal effects such as damage to gill and liver cells, kidney lesions were visible at concentrations less than 1ppm.[14] Synergistic effects with other pesticides such as 2,4-D, rotenone, or pentachlorophenol increased toxicity in fish.
I used it once but will NOT again...This is a scary chemical!
