A comprehensive study was performed to determine whether lead (Pb) in drinking water exceeded acceptable levels at a manufacturing and research site. Recent research indicates the possibility of abnormal adolescent development if the mother's blood lead levels exceed 15 micrograms lead per dL of whole blood. Using Environmental Protection Agency (EPA) estimates of average consumption and ratios correlating the amount of lead consumed to blood lead levels, a level of 10 micrograms/L of lead in water was determined to be acceptable. Water samples were collected from each type of water cooler and from faucets in every bathroom on site. Samples were collected that represented worst case exposures. Novel methods were used to identify the source of lead at those locations that exceeded the acceptable limit for lead. Control techniques are discussed. A laboratory study was performed to determine if lead could be prevented from leaching into drinking water from existing plumbing systems by treating the system with carbon dioxide gas.
开展了一项全面研究，以确定某制造与研究场所的饮用水中铅（Pb）含量是否超过可接受水平。近期研究表明，如果母亲全血中的血铅水平超过每分升15微克铅，则青少年发育可能出现异常。利用美国环境保护局（EPA）对平均饮水量的估计以及将摄入铅量与血铅水平相关联的比率，确定水中铅含量为10微克/升是可接受的。从现场每种类型的饮水机以及每个卫生间的水龙头采集了水样。采集的样本代表了最坏情况的暴露。采用新颖方法来确定那些铅含量超过可接受限值的地点的铅源。讨论了控制技术。进行了一项实验室研究，以确定通过用二氧化碳气体处理现有管道系统，是否能够防止铅从管道系统中浸出到饮用水中。
