执法机构成员接受了检查，了解他们在射击场的活动和接触铅对健康造成的不利影响。中枢神经系统和胃肠道症状很明显，并且与血液中原卟啉铅和锌水平相关。一半的人的血铅水平超过 40 μg/dl，4 人 (5%) 的血铅水平超过 60 μg/dl。对 3 个靶场的环境调查表明，通风不足的室内设施可能存在相当高的空气铅浓度，其浓度可达 900 μg m3，即当前职业安全与健康管理局 8 小时轮班标准的 4.5 倍。在枪械教员的医疗监测计划中应考虑铅效应的评估。事实证明，原卟啉锌测定是评估暴露者生物效应的合适且实用的方法，并且应该在负责室内射击场员工健康的医疗机构中提供。
Members of law enforcement agencies were examined for adverse health effects caused by their activities in firing ranges and exposure to Pb. CNS and gastrointestinal symptoms were prominent and correlated with blood Pb and Zn protoporphyrin levels. Half the group had blood Pb levels exceeding 40 .mu.g/dl, and 4 (5%) exceeded 60 .mu.g/dl. Environmental surveys of 3 firing ranges indicate that indoor facilities with insufficient ventilation may have considerable air Pb concentrations with levels to 900 .mu.g m3 or 4.5 X the current Occupational Safety and Health Administration standard for an 8 h shift. Evaluation of Pb effects should be taken into account in medical surveillance programs of firearms instructors. Zn protoporhyrin determination proved a suitable and practical way to assess biological effects among exposed persons and should be available at medical facilities responsible for the health of indoor firing range employees.
