In some areas, the risk levels of carbon trichloride, hexachlorobutadiene, carbon tetrachloride, chlorylene, tetracarp, trichloroethane , chloroform, gammexane and other pollutants all exceed 10-4, all above the harm value of 1, and these pollutants are likely to cause risks to human health.

而少数区域的六氯乙烷、六氯丁二烯、四氯化碳、三氯乙烯、四氯乙烯、1，1，2-三氯乙烷、氯仿和六六六等污染物风险等级均大于10-4，危害商均大于1，这些污染物均能对人体健康产生风险。

Organic chlorine compounds, including hexachlorethane , pentalin , hexachlorobutadiene, HCB, pentachlorobenzene, dioxin, gammexane, tetracarp, carbon tetrachloride , chloroform and etc.

有机氯化合物，包括六氯乙烷、五氯乙烷、六氯丁二烯、六氯苯、五氯苯、二恶英、六六六、四氯乙烯、四氯化碳和氯仿等污染物。

The main pollutants from this chemical plant is perchloroethane, pentachloroethane, hexachlorobutadiene and HCB, and such pollutants are present in the soil with high densities, some as high as 1%- 95%, of which the perchloroethane is near the purity of the corresponding product, and especially this part of the soil contains comparatively high-density persistent organic pollutant HCB, which makes it suitable to be disposed of together with other soils. Therefore it is suggest that this part of soil should be separately dug out and transported outside of the site.

化工厂的主要污染物质是六氯乙烷、五氯乙烷、六氯丁二烯和六氯苯，土壤中上述污染物的浓度非常高，有些达到1%至95%，其中六氯乙烷接近相应的产品的纯度，特别是这一部分含有较高浓度的持久性有机污染物六氯苯，不利于与其它土壤混合处理，建议将这一部分单独开挖出来并运出场外。

The highest content of HCB is 6,254 times higher than the B level standard set by the Ministry of Environmental Protection, carbon trichloride 9,330 times higher, hexachlorobutadiene 290.5 times higher.
