This book was released on 2000-10-21 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Incineration has been used widely for waste disposal, including household, hazardous, and medical wasteâ€"but there is increasing public concern over the benefits of combusting the waste versus the health risk from pollutants emitted during combustion. Waste Incineration and Public Health informs the emerging debate with the most up-to-date information available on incineration, pollution, and human healthâ€"along with expert conclusions and recommendations for further research and improvement of such areas as risk communication. The committee provides details on: Processes involved in incineration and how contaminants are released. Environmental dynamics of contaminants and routes of human exposure. Tools and approaches for assessing possible human health effects. Scientific concerns pertinent to future regulatory actions. The book also examines some of the social, psychological, and economic factors that affect the communities where incineration takes place and addresses the problem of uncertainty and variation in predicting the health effects of incineration processes.

Available in PDF, EPUB and Kindle. Book excerpt: Viable pathogens are generally present at every stage of wastewater treatment. Thus a potential airborne infectious pathway due to microbial aerosols exists, particularly at activated sludge treatment plants. In this study the concentration of sewage-borne indicator bacteria and viruses in effluent aerosols was determined and the exposure to such aerosols by treatment plant workers was estimated. Initial aerosol collection with fog-gage screen collectors yielded erratic results due especially to lack of control over sampled air volume and slit openings too large for effective collection. Standard Andersen and glass impinger collectors were used throughout the field study. Areas downwind of aeration basins yielded as much as 1 657 CFU/m^3 total bacteria and 1.8 CFU/m^3 coliphage. These aerosols were mostly 2.1 to 3.3 μm droplet nuclei with a high potential for inhalation and bronchial retention. The inhalation of microbial aerosols by Wahiawa treatment plant workers was estimated to be between 48 to 94 total bacteria/person/day above background levels. The inhaled total coliform level may average 8 to 27 CFU/person/day. This usually short duration and sometimes intense exposure could not be implicated directly to cause adverse health effects. Correlations of statistical tabulations of sick-leave illness with degree of exposure were not significant at the 0.01 or the 0.05 level.

Available in PDF, EPUB and Kindle. Book excerpt: This book argues, that without methods, there can be no research. Effective research requires effective methods, not always easy to come by. The development of methods in environmental virology became a focus of growing interest about two decades ago. Progress has been significant since that time in pure experimental systems, where there are no interferences, consistent high recoveries of viruses from environmental waters has been achievable for some time. In the natural environment, however, in relatively clean waters, substances such as humic and fulvic acids interfere with viral recoveries and average recovery rates probably do not reach 20%. With sewage sludges and shellfish, recoveries are undoubtedly much lower. Yet, even relatively low viral recovery rates have made possible the detection of viral hazards in drinking waters. The hazards that exist are undoubtedly much greater than those demonstrated with the relatively inefficient methods inefficient methods developed thus far. Improving methods, as they are developed in the years to come, will undoubtedly bring the true extent of the hazards into better perspective.
