Much new material has been added to this second edition. Besides a totally new
chapter on radionuclides, the text has been reorganized and updated with separate
chapters on metals, light nonaqueous phase liquids (LNAPLs), dense nonaqueous
phase liquids (DNAPLs), and biodegradation. Also, some end-of-chapter exercises
have been added. The dictionary of inorganic pollutants has been enlarged and
some important organic pollutants added.
The presence of substances in groundwater may be affected by naturally occurring processes
as well as by actions directly associated with human activities. Naturally occurring processes
such as decomposition of organic material in soils or leaching of mineral deposits can result in
increased concentrations of several substances. Those of health concern include arsenic,
fluoride, selenium, uranium, nitrate, metals, and radionuclides such as radon. Problems of
aesthetic quality and acceptance may be caused by iron, manganese, sulphate, chloride and
organic matter. ...
The Baltic Sea is a unique basin, being productive with intensive fishing potential
and has therefore been the object of many studies. It is a brackish, nontidal,
relatively shallow and semi-enclosed sea. The Baltic is located at a high latitude,
hence one of its characteristic features is ice. Another unique geographical
pattern are the archipelagos located off the coast of Stockholm which consist of
more than 25 000 islands. The relative ionic concentration of toxic substances e.g.
chemical elements is generally higher in the low-saline Baltic Sea than compared
to the North Sea....
Examine the cause and effects of the release of an industrial cyanide/heavy metals impoundment into a major European river system. • Examine the heavy metals release from a tailings dam failure in Southwestern Spain. • Describe the science and toxicological impacts of ionizing radiation resulting from radionuclides.
