背景低收入和中等收入国家的电子废物回收工人由于在非正规电子废物处理场所的工作性质，有可能受到职业伤害。然而，对于与这种工作环境相关的压力、噪音、职业伤害和健康风险的研究有限。本研究评估了伤害的经验，噪音暴露，并强调在大型回收网站的Agbogbloshie市场，阿克拉，Ghana.MethodsParticipants电子废物工人的风险因素完成了一项调查，解决他们的工作，健康状况，压力，暴露于几个职业危害（包括噪音），在工作中使用个人防护设备，和伤害的经验。一部分参与者还完成了个人噪声剂量测量。使用Poisson回归来评估参与者经历的伤害次数与调查中评估的各种因素之间的关联。结果46名男性电子废物工人完成了调查，26名完成了噪音剂量测量。在过去的6个月里，参与者平均每人经历了9.99.6次伤害（范围：1-40）。损伤以撕裂伤为主（65.2%），最常见的损伤部位是手（45.7%）。很少使用个人防护设备。平均时间加权平均噪音水平为78.8 +/- 5.9 dBA。更高的感知压力，更大的年龄，更差的健康状况，不使用手套，并参与拆卸活动与受伤人数增加。在控制了这些风险因素中的每一个之后，感知压力水平和感知噪声暴露与显著更多的伤害数量相关。结论pid = Par 4我们的研究在非正式的电子废物回收者中发现了大量的伤害，我们发现，更高水平的感知压力和感知噪声与职业伤害数量的增加相关，即使在控制了其他伤害风险因素之后。
BackgroundElectronic waste (e-waste) recycling workers in low and middle-income countries have the potential for occupational injuries due to the nature of their work at informal e-waste sites. However, limited research exists on stress, noise, occupational injuries, and health risks associated with this work environment. This study evaluated injury experience, noise exposures, and stress risk factors among e-waste workers at the large recycling site in the Agbogbloshie market, Accra, Ghana.MethodsParticipants completed a survey addressing their work, health status, stress, exposures to several occupational hazards (including noise), use of personal protective equipment at work, and injury experience. A subset of participants also completed personal noise dosimetry measurements. Poisson regression was used to evaluate the association between the number of injuries experienced by participants and various factors evaluated in the survey.ResultsForty-six male e-waste workers completed the survey, and 26 completed a noise dosimetry measurement. Participants experienced an average of 9.99.6 injuries per person in the previous 6months (range: 1-40). The majority of injuries were lacerations (65.2%), and the most common injury location was the hand (45.7%). Use of personal protective equipment was rare. The mean time-weighted average noise level was 78.8 +/- 5.9 dBA. Higher perceived stress, greater age, poorer health status, not using gloves, and involvement in dismantling activities were associated with an increased number of injuries. After controlling for each of these risk factors, perceived stress level and perceived noise exposure were associated with a significantly greater number of injuries.Conclusions p id=Par4 Our study identified a large number of injuries among informal e-waste recyclers, and we found that higher levels of perceived stress and perceived noise were associated with an increased number of occupational injuries, even after controlling for other injury risk factors.
