How toxic is lambda-cyhalothrin on humans?
*Individuals working with lambda-cyhalothrin in laboratories reported symptoms of facial tingling and burning sensations. Symptoms began within 30 minutes of exposure and lasted for 6 hours to 2 days. All incidents involved people handling relatively pure or concentrated lambda-cyhalothrin.
*Four field workers out of 38 reported adverse health effects from exposure to lambda-cyhalothrin. Three of the workers reported skin irritation or burning sensations that developed 45-60 minutes after exposure and lasted for 5, 18, and 72 hours. The other worker experienced a skin rash that developed 24 hours after exposure and lasted several days. All workers handled concentrated lambda-cyhalothrin, and three of the four applied diluted solutions.
*Lambda-cyhalothrin may cause irritation to the skin, throat, nose, and other body parts if exposed. Skin tingling, burning, and prickling feelings, particularly around the face, are unique temporary symptoms of exposure. Other symptoms may include dizziness, headache, nausea, lack of appetite, and fatigue. In severe poisonings, seizures and coma may occur.
