[Chemical safety (1): The origin of the problem].

The genesis of the vast problem--of cognitive and applicatory nature--referred to as chemical safety, has been presented. Chemical safety studies involve all possible sources of man's exposure to chemical compounds, which is aimed at an effective control of adverse health effects. The authors have set up a definition according to which chemical safety occurs where exposure to chemical compounds coming from various sources causes a specific health risk not higher than the socially accepted level. The contribution of Poland to the International Program of Chemical Safety (IPCS) should promote the exchange of experiences and access to scientific and technological information.
