对受污染场地的评估通常以土壤中有害化合物的化学分析为基础。这足以评估受污染土壤的环境危害，也足以评估所应用的补救技术的效率。化学分析数据无法提供有关外源性物质和降解产物复杂混合物生物利用度的信息，但生物测定的结果可以综合混合物中污染物的影响。为了保护人类健康和环境质量，评价工业污染土壤的生态毒理学效应是分析化学技术的重要补充。焦炉土壤的监测和评价的土地耕作处理技术，在现场进行的中试规模的安装，是由电池的生态毒理学试验：急性，慢性和遗传毒性试验。受污染的土壤样本显示，不同物种的毒性效应，主要是由于高浓度的多环芳烃（多环芳烃）。土地耕作处理后，土壤样品的毒性显着降低，证实了土地耕作过程中指出的低分子量多环芳烃浓度显着降低的有效性。不同的生态毒理学试验的比较分析允许建立和验证一个更合适的程序监测多环芳烃污染的土壤。(C)出版社：Wiley Periodicals，Inc.
Assessment of contaminated sites is usually based on chemical analyses of hazardous compounds in soil. This is enough either to assess the environmental hazard of contaminated soil nor to evaluate the efficiency of applied remediation techniques. Information on the bioavailability of complex mixtures of xenobiotics and degradation products cannot be provided by chemical analytical data, but results from bioassays can integrate the effects of pollutants in mixtures. In the preservation of human health and environmental quality, it is important to evaluate ecotoxicological effects of contaminated industrial soils to complement the techniques of analytical chemistry. The monitoring of a coke oven soil and the evaluation of the landfarming treatment technique, conducted on-site in a pilot scale installation, was done by a battery of ecotoxicological tests: acute, chronic, and genotoxicity tests. Contaminated soil samples revealed toxic effects for different species mainly due to high concentrations of polycyclic aromatic hydrocarbons (PAHs). After landfarming treatment, soil samples presented significant reduction in toxicity, confirming the effectiveness of the landfarming process pointed out by a significant reduction in low molecular weight PAH concentrations. Comparative analysis of the different ecotoxicological tests allowed the establishment and validation of a more suitable procedure for the monitoring of PAH contaminated soils.
