摘　　要：以粤港澳大湾区某水泥厂地块为研究对象,对土壤和地下水氟化物污染情况进行调查分析,并按推荐模型计算一类用地土壤筛选值及《地下水质量标准》Ⅲ类标准限值为评价标准。结果表明:研究区内土壤氟化物平均含量虽未超过筛选值但普遍较高,且表层土壤含量较底层较高;生产区及下风向空地区域氟含量浓度较高,表明受水泥粉尘扬撒或原料堆存保存不当影响。地下水浓度存在大面积的氟化物污染,其污染集中于中部生产区域,推测可能由于原料运输、使用和保存不当所致。提出了加强水泥行业原辅料保存管理、加强粉尘污染防治等环境管理要求。The fluoride contents in soil and groundwater was investigated of in a cement plant in Guangdong-Hong Kong-Macao Greater Bay Area.The study comprehensively evaluated the fluoride pollution use potential ecological hazard index method.The soil was evaluated by risk screening values for soil contamination of development land.The groundwater was evaluated byClassⅢstandard limitsof standard for groundwater quality.The results showed that although the average content of fluoride in soil in the study area did not exceed the risk screening values for soil contamination of development land,the content was generally high.The content of fluoride in the surface soil was higher than that in the bottom soil.And the concentration of fluoride in the production area and the open area downwind was higher.The concentration of fluorine in the production area and downwind open area is higher,indicating that it is affected by cement dust spreading or improper storage of raw materials.There is widespread fluoride contamination in groundwater concentrations,andthe pollution which is concentrated in the central production area.It may be caused by improper transportation,use and preservation of raw materials.Based on the analysis of pollution characteristics,it is necessary to strengthen the preservation and management of raw and auxiliary materials in cement industry and strengthen prevention and control of dust pollution.
