Automotive Chemistry Testing
Volatile organic compounds are main sources of in-car air pollution, which may cause pungent odour and health-harming to human beings. Meanwhile, to avoid the disposal of hazardous waste and to prevent their release into the environment, it's also important to take the form of reduction and control of hazardous substances in vehicles. STQ provides automotive chemistry testing to ensure that the materials used are safe and meet relative requirements.
