江西某地“癌症高发区”地质环境现状及评价

Present situation and assessment of geological environment of high cancer incidence area in Jiangxi Province

江西某地“癌症高发区”的报道引起了社会的广泛关注。通过对该地土壤、水体、降尘地质环境调查评价,认为调查区土壤环境质量较好,为清洁区,仅镍元素达轻度污染级。地下水质量为较差级,外围为优良级。饮用水源地水质综合评价为较差级,有机氯农药检出2项,多环芳烃检出10项,萘达到轻度污染级。区域地质、水文地质背景不具特殊性,土壤、水体地质环境与周边南昌地区无明显异常,是否与癌症发病有直接的关系,尚需作进一步的调查研究工作。降尘污染较为严重,污染因子主要为镉,应引起重视。

The news report of high cancer incidence area in cern of the public. Based on the comprehensive survey Jiangxi Province, aroused the extensive conand assessment of geological environment of soil,water body and dust in the area, we found the area had the better environmental quality of soils olny with light degree Ni pollution, the worse quality of groundwater by contrast with the excellent quality of that in the periphery. The worse quality of drinking water are determined. Two types Organochlorine Pesticides and ten types Polycyclic Aromatic Hydrocarbons（PAHs） in water are found, in which Naphthalene concentration is up to the light pollution degree. Whether the indistinctive regional geology and hydrogeology setting, the similar geological environment of soil and water body in comparison with those of the periphery related to the cancer incidence directly, need to be confirmed further by researching. The relatively serious dust pollution in which pollution factor is mainly Cd should be recognized.
