Hazardous chemicals

Whether a chemical is hazardous to humans or ecosystems depends on its properties, form, the environmental medium in which it is found, its concentration and the stages of potential exposure.

The public should be aware of commonly used products that contain hazardous substances .

Tracing the path of certain hazardous chemicals in the environment is frequently complicated by the fact that the same chemicals occur naturally. Once released into the environment, chemicals become involved in the complex natural atmospheric, geo-chemical and biological cycles.

Ironically, the pesticides that are now blacklisted in some countries were for many years viewed as a chemical triumph over nature
