Awareness of electronic waste (e-waste) improves safety practices among workers, thereby reducing health risks associated with pollutants. Investigating the awareness and safe practices among these workers could help identify areas for improvement, a task not yet undertaken in Bangladesh. Consequently, this study aimed to examine the awareness, safety measures, and associated factors among e-waste workers in the country. In this cross-sectional study, 236 workers from an e-waste recycling facility located near Dhaka were interviewed using a semi-structured questionnaire from August to September 2022. Eight questions captured information on socio-demographics and work factors, 24 questions on e-waste awareness, and 11 questions on safety practices. Total awareness and safety scores were calculated and categorized as "good" and "poor" based on a cut-off point of 80% of the total score. Bivariate and regression analyses were done to determine associated factors. Only 25% of workers had good e-waste awareness; major knowledge gaps were regarding minimization, health hazards, and environmental impact. Good awareness was significantly associated with female gender, higher education, income, smoking, experience ⩾5 years, and training. About 58% followed good safety practices, but the use of boots and helmets was inadequate. Good safety practices were significantly associated with higher education, income, smoking, experience, training, and overtime work. On multivariable analysis, those with higher education had 12 times (95% CI 4.83-32.81) and 6 times (95% CI 2.94-12.81) higher odds of good awareness and practices, respectively. Trained workers had 3.6 times (95% CI 1.67-7.52) higher odds of good practices. There was a significant correlation between awareness and practices (r = .70, P < .001). The study found poor awareness and inadequate safety practices related to e-waste among the workers. Urgent interventions like training, the use of protective gear, and stringent policies are warranted to increase awareness and safety behaviors.
对电子垃圾(电子废弃物)的认知提高了工人的安全操作水平,从而降低了与污染物相关的健康风险。调查这些工人的认知和安全操作情况有助于确定需要改进的方面,而孟加拉国尚未开展这项工作。因此,本研究旨在调查该国电子垃圾处理工人的认知、安全措施及相关因素。在这项横断面研究中,2022年8月至9月,使用半结构化问卷对达卡附近一家电子垃圾回收设施的236名工人进行了访谈。八个问题获取了社会人口统计学和工作因素方面的信息,24个问题涉及电子垃圾认知,11个问题涉及安全操作。计算了总体认知和安全得分,并根据总分的80%这一临界点将其分为“良好”和“较差”。进行了双变量和回归分析以确定相关因素。只有25%的工人对电子垃圾有良好的认知;主要的知识差距在于减少产生、健康危害和环境影响方面。良好的认知与女性性别、高等教育、收入、吸烟、工作经验≥5年以及接受培训显著相关。约58%的工人遵循良好的安全操作规范,但靴子和头盔的使用不足。良好的安全操作规范与高等教育、收入、吸烟、工作经验、培训以及加班工作显著相关。在多变量分析中,受过高等教育的人具有良好认知和良好操作规范的几率分别高出12倍(95%置信区间4.83 - 32.81)和6倍(95%置信区间2.94 - 12.81)。接受过培训的工人具有良好操作规范的几率高出3.6倍(95%置信区间1.67 - 7.52)。认知和操作规范之间存在显著相关性(r = 0.70,P < 0.001)。研究发现工人对电子垃圾的认知较差且安全操作规范不足。有必要采取诸如培训、使用防护装备和严格政策等紧急干预措施来提高认知和安全行为。
