چکیده
Toxic Chemicals These substances are hazardous to human health and the environment. In 2004 North American industrial facilities generated over 5 million tonnes of toxic chemicals as production-related pollutants and waste (see box). Despite this large amount, data for comparable industries and chemicals in Canada and the United States reveal encouraging trends. Over the period 1998–2004, total releases of carcinogens and developmental/reproductive toxicants declined by 26 percent in the United States and Canada (see graph), compared with a 15 percent reduction in all tracked chemicals. Mexican data are not available for this time period. Although releases to most media for these Industrial Pollution and Waste
