Other Toxic Substances

     Polluted River In the United Kingdom The pollution of rivers and streams with chemical contaminants is one of the world's most critical environmental problems. Chemical pollution entering rivers and streams comes from two major sources: point pollution and non-point pollution. Point pollution involves those pollution sources which can be specifically identified, such as factories, refineries or outfall pipes. Non-point pollution involves pollution from sources that cannot be precisely identified, such as runoff from agricultural or mining operations or seepage from septic tanks or sewage drain fields. It is estimated that each year 10 million people worldwide die from drinking contaminated water.

     Toxic substances are chemicals and mixtures of chemicals the manufacturing, processing, distribution, use, and disposal of which present an unreasonable risk to human health and the environment. Most of these toxic substances are synthetic chemicals that enter the environment and persist there for long periods of time. Major concentrations of toxic substances occur in chemical dump sites. If they seep into soil and water, the chemicals can contaminate water supplies, air, crops, and domestic animals, and have been associated with human birth defects, miscarriages, and organic diseases. Despite known dangers, the problem is not lessening. In a recent 15-year period, more than 70,000 new synthetic chemicals were manufactured, and new ones are being created at the rate of 500 to 1,000 each year.
