The present survey comprises today�s knowledge of environmental pollution�in particular of the atmosphere�by PAH and of the biological effects of this class of substance, putting special emphasis on their carcinogenic activity. The research data and conclusions derived therefrom are meant to assist the government of the Federal Republic of Germany in determining an air quality standard.
