Environmental fluctuations and biological variability affect the establishment of baseline data in studying the ecotoxic effects of pollutants. Since substantial fluctuations are recorded for various ecological indices, it becomes problematic to establish whether an observed change in some ecological parameters represents a variation caused by presence of a pollutant, or represents 'natural' fluctuations inherent in the ecosystem.Thus, ability to predict ecotoxic effect lies at the base of the diagnosis. Such diagnosis should employ characteristics that reflect the integrated response of component populations to perturbations and as well provide a comprehensive picture of ecosystem 'status'. Measurements become authentic and acceptable only when compared with normal values of the numerical parameter in question. 相似文献

The water pollution emissions by 13 of the largest pulp and paper companies, developed on the basis of monthly reports filed with the US Environmental Protection Agency (EPA) by these companies, indicate a wide disparity in the amount of pollution discharged by them into the nation's waterways. Furthermore, the net discharge of pollution in waterways by all firms is positive, which indicates that all the firms in the study pollute the nation's waterways to some degree. Information presented in this study will be useful for public issues, such as evaluating the effectiveness of the Clean Water Act, government's water pollution policy and abatement strategy, and management's effectiveness in abating water pollution. 相似文献

四川省城市环境空气质量及变化趋势 总被引:1,自引:0,他引:1
本文根据2000~2009年四川省24个地级城市例行空气监测数据,按照《环境空气质量标准》(GB3095-1996)中的二级标准,采用综合污染指数法分析了四川省近10年环境空气质量的现状、变化趋势及影响因素。结果表明:从年际变化看,可吸入颗粒物浓度呈下降趋势,二氧化硫、二氧化氮浓度变化较平稳;年内变化显示,各污染物浓度季节变化明显,冬季污染最严重,污染程度由高到低的顺序为冬季、春季、秋季、夏季。全省综合污染指数呈下降趋势,空气污染程度得到了明显缓解,空气质量逐渐变好。 相似文献

ABSTRACT: Confined production of poultry results in significant volumes of waste material which are typically disposed of by land application. Concerns over the potential environmental impacts of poultry waste disposal have resulted in ongoing efforts to develop management practices which maintain high quality of water downstream of disposal areas. The timing of application to minimize waste constituent losses is a management practice with the potential to ensure high quality of streams, rivers, and lakes downstream of receiving areas. This paper describes the development and application of a method to identify which time of year is best, from the standpoint of surface water quality, for land application of poultry waste. The procedure consists of using a mathematical simulation model to estimate average nitrogen and phosphorus losses resulting from different application timings, and then identifying the timings which minimize losses of these nutrients. The procedure was applied to three locations in Arkansas, and three different criteria for optimality of application timing were investigated. One criterion was oriented strictly to water quality, one was oriented only to crop production, and the last was a combination. The criteria resulted in different windows of time being identified as optimal. Optimal windows also varied with location of the receiving area. The results indicate that it is possible to land-apply poultry waste at times which both minimize nutrient losses and maximize crop yield. 相似文献
