中文摘要:
      本文通过近10年徐州市62口地下水监测井监测结果分析及健康风险评价,查明了徐州地区地下水氟化物的时空变化特征、非致癌风险指数大小等。研究结果表明:2011—2022年徐州市地下水氟化物含量相对较为稳定(0.05~2.90 mg/L),也存在差异性变化趋势。地下水高氟区主要位于丰县西北部,市区北部存在个别地下水氟化物含量较高点,睢宁县地下水氟化物含量整体相对较高。研究区高氟地下水的形成主要与高氟地质背景值和降水量有关。丰县、睢宁、市区部分区域未成年人HQ超标,超标监测点占比依次为4.0%、2.9%、1.4%。三类人群的健康评价显示HQ(未成年人)>HQ(成年女性)>HQ(成年男性),HQ最大值分布总体呈现丰县>睢宁>市区>沛县>新沂>邳州的规律,建议加强徐州地区氟化物非致癌风险预防。
英文摘要:
      Based on the analysis of monitoring results and health risk assessment of 62 groundwater monitoring wells in Xuzhou in recent 10 years, the temporal and spatial characteristics of fluoride in groundwater and the magnitude of non-carcinogenic risk index were studied. The results show that the fluoride content in groundwater of the Xuzhou remained relatively stable (0.05-2.90 mg/L) from 2011 to 2022, while also showing certain trends of differential change. The high fluoride area of groundwater is mainly located in the northwest of Fengxian County, and the fluoride content of groundwater in Suining County is relatively high. The formation of high-fluoride groundwater in this area is primarily related to the high-fluoride geological background values and the amount of precipitation. The juvenile HQ in Fengxian, Suining and some urban areas exceeded the standard, and the proportion of monitoring points exceeded the standard was 4.0%, 2.9%, 1.4%; The maximum distribution of HQ in the three groups showed the rule of Fengxian > Suining > urban > Peixian > Xinyi > Pizhou, HQ (minors) >HQ (adult female) >HQ (adult male), and the non-carcinogenic risk prevention of fluoride in this area should be strengthened.
