本研究的目的是确定与增加暴露于砷污染的土壤在肯塔基州附近的合作公共卫生响应的一部分的相关因素。对居民进行了暴露评估调查，并对脚趾甲和土壤样本进行了砷浓度分析。暴露变量和砷浓度之间的关联进行了评估，使用多变量广义估计方程。还使用标准化发病率地图对社区癌症发病率进行了生态评估。趾甲砷中位数为0.48微克/克（µg/g），是预期区域水平0.2 µg/g的两倍。平均居住地表层土壤砷含量为64.8 ppm。驻留浓度增加1 ppm与趾甲水平增加0.003 µg/g显著相关。从事挖掘的受访者的浓度为0.68微克/克，显著高于不从事挖掘的受访者。在受影响的邮政编码中没有观察到肺癌或膀胱癌的发病率显著升高。生活在土壤砷污染严重的地区可能导致（1）暴露增加;（2）居住地土壤砷浓度升高;（3）挖掘土壤的行为与趾甲砷水平升高有关。根据确定的土壤水平升高，建议居民离开受污染的环境，直到补救工作完成。其他建议包括定期保健后续行动。
The aim of this study was to identify factors associated with an increased exposure to arsenic-contaminated soil in a Kentucky neighborhood as part of collaborative public health response. An exposure assessment survey was administered to residents and toenail clippings and soil samples analyzed for arsenic concentration. The associations between exposure variables and arsenic concentrations were evaluated using a multivariate-generalized estimating equation. An ecological assessment of cancer incidence in the community was also conducted using standardized incidence ratio maps. Median toenail arsenic was 0.48 micrograms/gram (µg/g), twice the expected regional level of 0.2 µg/g. Mean residence surface soil arsenic level was 64.8 ppm. An increase of 1 ppm of residence concentration was significantly associated with a 0.003 µg/g rise in toenail levels. Concentrations for respondents who engaged in digging were 0.68 µg/g significantly higher compared to individuals who did not. No significantly elevated rates of lung or bladder cancer were observed in the affected ZIP codes. Living in areas with high soil arsenic contamination might lead to (1) increased exposure; (2) elevated residence soil arsenic concentrations and (3) the action of digging in the soil was associated with elevated toenail arsenic levels. Based upon elevated soil levels identified, residents were recommended to move from the contaminated environment until remediation was complete. Additional recommendations included regular health-care follow-up.
