This practical reference examines every potential means of exposure to water contaminants, provides in-depth discussion on toxicology, explains the most up-to-date techniques for evaluating human health risk, and develops a methodology for assessing the cumulative absorbed dose of contaminants through all routes of exposure, including ingestion, inhalation, and dermal. | Covering both federal and state efforts to monitor and treat water and discussing water safety regulations, Water Contamination and Health addresses indoor exposure to radon from water sources and exposure to chloroform in swimming pools ... highlights epidemiology, including the need to determine the actual correlation between chemical exposure and human health effects ... emphasizes the internal dose concept using a physiologically based pharmacokinetic model ... furnishes a case study on spontaneous abortion in pregnant women who were exposed to a specific chemical from a contaminated well ... explores the potential existence of carcinogens in water for human consumption ... and much more!

Introduces various techniques for soil remediation, including chemical fixation/stabilization, soil vapor extraction, thermally enhanced vapor stripping, biodegradation, and air sparging. This title describes the ex shu technique of thermal desorption of soil contaminants - a low-cost alternative to incineration for the removal of organics.

The ocean plays a central role in the global carbon cycle being by far the largest active reservoir. Atmospheric CO2 level depends on the CO2 concentration in the ocean surface layer, which is relatively low compared to mean oceanic values due to biological and physical carbon pumps. Although the ocean may take up much of the carbon released by the increased burning of fossil fuels, this capacity is limited because of the chemical buffering and a mismatch in time scales (oceanic mixing is much slower than anthropogenic perturbations).

A method was developed to determine the dimethyl sulphoxide (DMSO) reduction rate in activated sewage sludge at nearly natural conditions. Linearity of microbially produced dimethyl sulphide with incubation time and sample size was shown. Apart from a fast, sensitive and highly reproducible automatic analysis of dimethyl sulphide, simultaneous determination of mineralisation, respiration and phenol degradation rates was possible. The DMSO reduction rate of samples taken from a municipal sewage plant ranged between 2 and 3 micromol/(g dry matter per h), respiration and mineralisation rates between 30 and 80 micromol/(g per h). Added (13)C(6)-phenol was completely degradated after 96 h of incubation. A half-life of 14 h was calculated assuming first order decay. Dose response curves were obtained by incubating samples for 2, 6, 25, and 96 hours after addition of pentachlorophenol. At an incubation time of 6 h, the EC(50) values ranged from 20 mg/L (DMSO reduction) to 30 mg/L (phenol degradation) up to 180 mg/L (respiration and mineralisation). Increasing the incubation time to 96 h resulted in a lower EC(50) of 9 mg/L for DMSO reduction, whereas it increased to 500 mg/L for respiration and mineralisation.
