摘要:

Semivolatile organic pollutants (SVOP) have been linked to lung cancer mortality incidence in both the workplace and ambient environment. However, as a result of the complex nature of SVOP it has been very difficult to link specific classes of compounds with health effects in defined human populations. The present report outlines health effects, collection and analysis information pertaining to SVOP and is an attempt to highlight where improvements in the state‐of‐knowledge on these materials is clearly needed. A case study approach is utilized to characterize methodological approaches to the study of SVOP in ambient and source samples.

摘要:

Concentrations of P, Fe, Zn, Cu, Mn, Cr, Pb, Ni, Ag, Cd, As, Co, Hg, and Se in the influent and effluent of 25 sewage treatment systems in different metropolitan areas of the United States were measured. Attenuation of the concentrations of these elements in primary effluents, secondary effluents, and discharges, relative to raw sewage, was calculated. These calculations indicate that the best removal occurs for Pb, followed by Zn, Fe, Cr, Cd, Cu, P, Ag, Ni, Mn, and Co.

摘要:

The Air Land Water Analysis System (ALWAS) is a multi‐media environmental model for describing the atmospheric dispersion of toxicants, the surface runoff of deposited toxicants, and the subsequent fate of these materials in surface water bodies. ALWAS depicts the spatial and temporal distribution of contaminant concentrations in a watershed and the air above it. Linked in ALWAS are three submodels that provide for independent and partially coupled usage modes Dispersion and Deposition of Toxics (DiDOT); a modification, called NPSDEP, of the Non‐point Source Model; and Exposure Analysis Modeling System (EXAMS).
