本研究旨在评估华东地区8家注册电子产品回收企业员工的铅和噪声暴露情况，并提出减少这些暴露的控制策略。江苏省疾病预防控制中心（JSCDC）在第一次访视期间对健康和安全计划进行了走查和审查，并在第二次访视时进行了全班次个人和区域空气铅监测以及个人噪声暴露测量。对总共168名员工进行了两个轮班的监测。结果表明，从事玻璃破碎和阴极射线管拆卸工作的员工过度接触噪音和铅。空气中铅浓度范围为0.1 ~ 148 μg/m3，101个样品中有4个样品超过中国允许接触限值50 μg/m3。过度接触铅涉及阴极射线管拆卸和玻璃破碎。在塑料粉碎和玻璃破碎区工作的员工过度接触噪音。全班时间加权平均噪声水平范围为64至107 dBA，123个样本中有85个超过中国允许的接触限值85 dBA。建议在这些电子产品回收设施采取控制措施，减少铅和噪音的接触，包括改进铅保护和听力保护计划。
The purpose of this study was to assess employees’ exposure to lead and noise, and to recommend control strategies for reducing these exposures at eight registered electronics recycling facilities in Eastern China. Jiangsu Provincial Center for Disease Control and Prevention (JSCDC) performed a walkthrough and review of health and safety programs during a first visit and conducted full-shift personal and area air monitoring for lead, as well as personal noise exposure measurements on a second visit. Monitoring was performed over two work shifts for a total of 168 employees. Results indicated that employees working at glass breaking and cathode ray tubes dismantling were overexposed both to noise and lead. Airborne lead concentration ranged from 0.1 to 148 μg/m3; and 4 of the 101 samples were above the Chinese permissible exposure limit of 50 μg/m3. Overexposures to lead involved cathode ray tubes dismantling and glass breaking. Employees working at plastics shredding and glass breaking areas were overexposed to noise. Full-shift time-weighted average noise levels ranged from 64 to 107 dBA; and 85 of the 123 samples were above the Chinese permissible exposure limit of 85 dBA. Control measures to reduce exposure to lead and noise, including improvements in their lead protection and hearing conservation programs, at these electronics recycling facilities were recommended.
