全国环境达标形势分析 总被引:1,自引:0,他引:1
夏青 《环境监测管理与技术》1998,10(6):1-4
依据1996年的统计,全国工业污染源达标率在50%左右,在的省份达标率低于40%,环保重点城市达标率在30%~40%,环境达标任务十分艰巨,为使全国工业污染源在2000年底实现达标排放,全国46个环保重点城市实现双达标,提出对落后的企业继续推行“关,停,禁,改,转”方针:国家制定国家支持,地方,企业自筹资金用于环境保护,真正使我国环境保护的基础能力建设达到新水平。 相似文献

Improvement of the BCR three step sequential extraction procedure prior to the certification of new sediment and soil reference materials 总被引:47,自引:0,他引:47

The Standards, Measurements and Testing Programme (formerly BCR) of the European Commission proposed a three-step sequential extraction procedure for sediment analysis, following extensive expert consultations and two interlaboratory studies. This scheme was recently used to certify the extractable trace element contents of a sediment reference material (CRM 601). Although this procedure offers a means to ensure the comparability of data in this field, some difficulties concerning the interlaboratory reproducibility still remain, and a new project is currently being conducted to determine the causes of poor reproducibility in the extraction scheme. The final objective of the project is the certification of new sediment and soil reference materials for their extractable contents of Cd, Cr, Cu, Ni, Pb and Zn. This paper presents the results of a small-scale interlaboratory study, which aimed to test a revised version of the extraction schemes by comparing the original and the modified protocols using the CRM 601 sample. This work offers an improvement to the BCR sequential extraction procedure through intercomparison exercises. This improved procedure will allow the obtaining of CRMs to validate analytical data in the analysis of soils and sediments, and it will also facilitate comparability of data in the European Union. 相似文献

Rethinking human health impact assessment 总被引:1,自引:0,他引:1
Most EIA programs around the world require the consideration of human health impacts. Yet relatively few EIA documents adequately address those impacts. This article examines how, why, and to what extent health impacts are analyzed in environmental impact assessments in the U.S. An empirical study of 42 environmental impact statements found that more than half contained no mention of health impacts. In the others, health impacts were analyzed narrowly, if at all, using risk assessment to quantify the carcinogenic potential of a single substance over a single generation. This analytic focus overlooks other significant morbidity and mortality risks, cumulative and intergenerational effects, and broader determinants of health. This article investigates these problems and provides recommendations to improve human health impact assessment, using strategic environmental assessment, qualitative health data, health outcomes in addition to cancer, and a precautionary approach to risk. 相似文献

Organophosphate (OP) and carbamate (CP) pesticides act by the inhibition of acetylcholinesterase (AChE). This enables the use of this enzyme for the detection of these pesticides in the environment. While many studies have looked at the effect of single pesticides on AChE, the effect of mixtures of pesticides still requires extensive investigation. This is important to evaluate the cumulative risk in the case of simultaneous exposure to multiple pesticides. Therefore we examined the effect of five different pesticides (carbaryl, carbofuran, parathion, demeton-S-methyl, and aldicarb) on AChE activity to determine whether combinations had an additive, synergistic, or antagonistic inhibitory effect. Results indicated that the mixtures had an additive inhibitory effect on AChE activity. The data from the assays of the mixtures were used to develop and train an artificial neural network (ANN) which was then utilised successfully for the identification of pesticides and their concentrations in mixtures. This study is significant because it evaluated mixtures of OPs and CPs where previous studies focused on either OPs or CPs. Previous studies have only examined up to three pesticides while this study evaluated mixtures of five pesticides simultaneously. This is also the first study where an ANN was able to utilise data from the inhibition of a single enzyme to differentiate five different pesticides and their concentrations from mixtures. 相似文献
