The interaction of chemicals with biological organisms is as old as life itself. Chemical pollution is usually considered to be human interference with natural chemical cycles and the release of man-made, unnatural compounds. The article traces five areas of chemical pollution and health hazards: air pollution, water pollution, occupational exposure, pollution from agricultural practices and contamination of food. It is suggested that historic perspective can aid in rational and prudent evaluation of present-day pollution problems.
