Is Automotive Urea Harmful to the Human Body?

[SanEloise]

Under normal circumstances, automotive urea is not harmful to the human body (if it comes into contact with the skin, simply rinse it off with plenty of soapy water or clean water, but be sure to avoid contact with eyes and ingestion). Below is a detailed introduction to urea: 1. Automotive urea consists of 32.5% high-purity urea and 67.5% deionized water. Under high-temperature conditions, automotive urea may release ammonia gas, which can have corrosive and irritating effects on human skin tissues. Prolonged exposure to ammonia gas may lead to symptoms such as skin pigmentation or ulcers. (If such symptoms occur, seek medical attention immediately to avoid more serious consequences.) 2. The function of automotive urea is: In the Selective Catalytic Reduction (SCR) system of diesel vehicles, automotive urea helps catalyze the reduction of nitrogen oxides in the exhaust into harmless nitrogen (N2) and water, thereby reducing harm to the environment and human health.
