摘要 目的评价硼工业地区不同人群经饮食的硼摄入情况。方法于2003年7月—2004年9月以某硼矿开采和加工区域的硼作业工人(硼暴露组)、生活在硼工业区附近的非硼作业工人(社区对照组)和远离硼工业区的人群(背景对照组)作为研究对象,所有研究对象均为成年健康男性,用副盘法采集了24h的饮水和饭菜样品,分析了日饮食量,测定了饮食硼暴露量及摄入量。结果硼暴露组、社区对照组和背景对照组的日饮水量平均值分别为1575、1138和1232ml/d,日饭菜食用量(湿重)平均值分别为1867、2169和1664g/d,折合为干重分别为496、547和401g/d。饮水平均硼浓度分别为2.05、0.86和0.05mg/L;饭菜平均硼含量分别为9.46、6.19和3.29mg/kg(干基);饮食平均日硼摄入量分别为8.00、4.25和1.40mg/d。饮用严重受硼污染的职工食堂井水并在该食堂用餐的工人的日饮食硼暴露为95.5~469mg/d,平均为219.0mg/d。结论生活在硼矿区域的工人硼暴露的危险程度远高于其他人群,值得关注。 Objective To assess boron intake through food and drinking water for the people living in the boron industrial area.Methods Workers from boron mining and processing plants were selected as the exposure group,the other workers from the area where was near to the boron industrial area were selected as the community control group and peoples from the area where was far from boron industrial area were selected as the background control group,all the subjects were healthy adult men,Jul.2003-Sep.2004.Total 24 h f...
