Environmental concerns, nonbiodegradable

Heavy metals are important members of Dirty Dozen Club of toxic pollutants encountered in various ecosystems of the environment. The dissolved metals (particularly heavy metals) escaping into the environment pose a serious health hazard. These metals have been classified as priority pollutants by the U.S. Environmental Protection Agency. Heavy metal pollution in the aquatic system has become a serious threat today and of great environmental concern as they are nonbiodegradable... 

Environmental. The growth in the population of the world has been accompanied by increases in consumption and the production of waste. Environmental engineering is concerned with the reduction of existing pollution in the air, in the water, and on land, and the prevention of future harm to the environment. Issues addressed include pollution from manufecturing and other sources, the transportation of clean water, and the disposal of nonbiodegradable materials and hazardous and nuclear waste. Because pollution of the air, land, and water crosses national borders, environmental engineers need a broad, global perspective.
