This article is a critical analysis of the treatment potential of bioremediation technology to degrade eight major environmental pollutants, polycyclic aromatic hydrocarbons, phenols, pentachlorophenols, creosote, polychlorinated biphenyls, trichloroethylene, chlorobenzoates, and chlorophenols. The discussion includes information on transformation mechanisms, identification of intermediate metabolites, elucidation of partial or complete pathways, effects of environmental parameters, as well as current and future industrial application. Results indicate that bioremediation used in conjunction with other physical and chemical treatment methodologies can effectively transform most prevalent nonchlorinated organic contaminants and some chlorinated contaminants, such as creosote and pentachlorophenol, into innocuous materials. Successful biodegradation of several other chlorinated organic compounds, notably polychlorinated biphenyls and trichloroethylene, is currently possible only under controlled laboratory conditions. Future successful field applications, however, appear promising. 相似文献

The ability of Section 404 of the Clean Water Act to act as an effective, efficient, and equitable land-use planning tool
was assessed through a survey of Section 404 permits in Wisconsin. In a six-month period of permitting, the 404 program reduced
wetland losses in the state by 15%. Several factors were examined that may affect permit decisions; these factors are water
dependency, alternatives, project type, wetland type, and public or agency comments. Only the water dependency of the project
had a statistically significant effect on permit decisions, although development projects that were perceived to provide public
good were more likely to be permitted. Environmental impacts of a proposed fill project were not adequately assessed in any
of the permit decisions. Because of the way Section 404 is interpreted and administered by the US Army Corps of Engineers,
increasing net benefits and achieving an equitable distribution of those benefits is difficult. The corps does not perform
any functional evaluations of wetlands nor do they attempt to measure economic value and environmental impacts. In addition,
the 404 review process is, in effect, inaccessible to the public. The de facto interpretations of the Section 404 regulations
and a lack of program funding and trained personnel all contribute to the program's ineffectiveness. 相似文献
