Abstract
In order to determine the health risk derived from the presence of heavy metals on the residents of a town in the North of Mexico, 27 samples were taken from a tailings dam at a mine in "Cerro de Mercado". Among the various metals and metalloids found, antimony and chromium exceeded the permissible concentration values established by the Mexican legislation, so mining waste in that region was considered to be hazardous and harmful to health. The risk assessment was carried out using the Spatial Analysis and Decision Assistance software, selecting a recreational setting with a short time exposure, and a residential setting with long exposure, obtaining as a result, that the health of the residents nearby the mine will not be damaged by metals and metalloids exposure existing in the tailings.
为了确定重金属对墨西哥北部一个城镇居民的健康风险，从“Cerro de Mercado”一座矿山的尾矿坝上采集了27个样本。在发现的各种金属和准金属中，锑和铬超过了墨西哥立法规定的允许浓度值，因此该地区的采矿废物被认为是有害健康的。风险评估是使用空间分析和决策辅助软件进行的，选择了一个短时间暴露的娱乐场所和一个长时间暴露的住宅场所，结果表明，尾矿中存在的金属和准金属暴露不会损害矿山附近居民的健康。
