WebCyfluthrin is moderately toxic to mammals with an oral LD50 of 850–1200 mg kg −1 in rats. Large doses of cyfluthrin cause excess salivation, irritability, tremors, incoordination, convulsions, and a fall in blood pressure. The acute toxicity of cyfluthrin increases at lower temperatures, and it is also acutely toxic when inhaled. Human Cypermethrin is moderately toxic through skin contact or ingestion. It may cause irritation to the skin and eyes. Symptoms of dermal exposure include numbness, tingling, itching, burning sensation, loss of bladder control, incoordination, seizures and possible death. Pyrethroids may adversely affect the central nervous system. Human volunteers given dermal doses of 130 μg/cm on the earlobe experienced local tingling and burning sensations. One ma…
