To determine if users of indoor firing ranges may be at risk from lead exposure, we studied a law enforcement trainee class during three months of firearms instruction. Blood lead levels were obtained before training and at four-week intervals during training. Air lead levels were measured three times during instruction. Blood lead levels rose from a pre-training mean of 0.31 mumol/L to 2.47 mumol/L. Mean air lead levels were above 2,000 micrograms/m3, more than 40 times the Occupational Safety and Health Administration's standard of 50 micrograms/m3. Cumulative exposure to lead and the change in blood lead were positively correlated. Control measures need to be studied to determine their efficacy in decreasing or eliminating this health risk.
为了确定室内射击场的使用者是否可能面临铅暴露风险，我们在三个月的枪支训练期间对一个执法学员班进行了研究。在训练前以及训练期间每隔四周测量血铅水平。在训练期间三次测量空气中的铅含量。血铅水平从训练前的平均0.31微摩尔/升升至2.47微摩尔/升。空气中铅的平均含量超过2000微克/立方米，是职业安全与健康管理局50微克/立方米标准的40多倍。铅的累积暴露量与血铅变化呈正相关。需要研究控制措施，以确定其在降低或消除这种健康风险方面的效果。
