A study released on Wednesday warned that one of the world's most common insect repellents acts on the central nervous system in the same way as some insecticides and nerve gases, AFP reported. Researchers say moderate use of the chemical compound deet is most likely safe, but experiments on insects, as well as on enzymes extracted from mice and human neurons, showed for the first time that it can interfere with the proper functioning of the nervous system. Many experts are urgently calling...

DEET, the active ingredient in many insect repellents, has been found to be neurotoxic in insects and mammals, French researchers reported Tuesday. Because of their finding, researchers are saying more investigations are needed quickly to either confirm or dismiss potential neurotoxicity to humans, the researchers said in a news release. We've found that DEET is not simply a behavior-modifying chemical but also inhibits the activity of a key central nervous system enzyme, acetycholinesterase,...
