Occupational exposure associated with unstructured, informal e-waste recycling has received very limited attention. This study aimed to quantify the occupational physical exposures among informal e-waste workers at the largest e-waste site in Africa. A cross-sectional field survey of 163 male e-waste workers was conducted using a self-report occupational physical activity questionnaire, along with direct work observations, and pedometer estimates of walking activity for a subset of workers (n = 42). Results indicated significant differences in self-reported 7-day work exposures among the three main e-waste job categories, namely, collectors (n = 70), dismantlers (n = 73) and burners (n = 20). Prolonged walking, sitting and standing on five or more days in the workweek was frequently reported by collectors (87%), dismantlers (82%) and burners (60%), respectively. Nearly 90% of collectors and burners and 60% of dismantlers reported lifting and carrying on five or more days in the workweek. The exposure combinations identified suggest a risk for musculoskeletal disorders (MSDs). Findings call attention to the need for research examining potential associations between physical exposures and MSDs affecting e-waste workers in Agbogbloshie. The high exposure variability both between and within workers has implications for future exposure assessments conducted in unregulated, informal work settings.
与非正规、非正式电子垃圾回收相关的职业暴露受到的关注非常有限。本研究旨在量化非洲最大电子垃圾处理场中非正式电子垃圾处理工人的职业身体暴露情况。对163名男性电子垃圾处理工人进行了横断面现场调查,采用了自我报告的职业身体活动问卷,同时进行了直接工作观察,并对一部分工人(n = 42)使用计步器估算了步行活动量。结果表明,在三种主要的电子垃圾工作类别中,即收集者(n = 70)、拆解者(n = 73)和焚烧者(n = 20),自我报告的7天工作暴露存在显著差异。收集者(87%)、拆解者(82%)和焚烧者(60%)分别经常报告在工作周的五天或更多天里有长时间行走、坐着和站立的情况。近90%的收集者和焚烧者以及60%的拆解者报告在工作周的五天或更多天里有搬运重物的情况。所确定的暴露组合表明存在肌肉骨骼疾病(MSD)的风险。研究结果提醒人们注意,需要开展研究,考察身体暴露与影响阿博布罗西电子垃圾处理工人的MSD之间的潜在关联。工人之间以及工人内部的高暴露变异性对在无监管的非正式工作环境中进行的未来暴露评估具有影响。
