Knowledge, Attitude and Practice Study of Health Risks Among E-waste Recyclers in Delhi.
Background: India is the fifth biggest producer of e-waste in the world, discarding 1.7 million tons in 2014. E-waste gets recycled mainly in the informal sector which means activities are largely unaccounted for. Hazardous chemicals and metals are released during recycling processes (lead (Pb) being the most common). Compared to other developing countries, there are few studies from India on the awareness of recyclers of health risks related to e-waste recycling.
Objectives: The aim of the present study was to assess the knowledge, attitudes, and practices (KAP) of health-related risks and behaviors among e-waste workers/recyclers belonging to the informal sector in Delhi and to determine the concentration of Pb levels in hair samples from a subset of workers from selected recycling sites.
Methods: A cross-sectional study was conducted in three e-waste informal recycling sites of Delhi: Seelampur, Mustafabad and Mandoli using an interviewer administered questionnaire among 220 e-waste workers. Percentages were presented for each KAP indicator. Analyses were computed using the statistical software STATA 14.2.
Results: It was observed that 24% of participants had knowledge of the meaning of e-waste and 36% knew the chemicals that could be released from e-waste handling. Personal protective equipment (PPE) was used by only 12% of the workers. Twenty-six percent (26%) perceived occupational injuries (cuts or burns) as mild and 20% perceived coughing immediately after work as mild. Explorative analysis showed a link between worker education level and the type of work practices employed. The median level of Pb concentration among hair samples was 8 mg/kg with inter-quartile range between 5.8 to 12.4 mg/kg.
Conclusions: Knowledge and practices among e-waste workers regarding the health hazards associated with e-waste recycling were poor with little knowledge of or attention to health risks. A comprehensive remediation package covering sensitization and awareness-building strategies of the health risks associated with informal e-waste recycling should be an urgent priority.
Participant consent: Obtained.
Ethics approval: Ethics approval was obtained from the Institutional Ethical Committee (IEC), Indian Institute of Public Health-Delhi.

期刊介绍：
The Journal of Health and Pollution (JH&P) was initiated with funding from the European Union and World Bank and continues to be a Platinum Open Access Journal. There are no publication or viewing charges. That is, there are no charges to readers or authors. Upon peer-review and acceptance, all articles are made available online. The high-ranking editorial board is comprised of active members who participate in JH&P submissions and editorial policies. The Journal of Health and Pollution welcomes manuscripts based on original research as well as findings from re-interpretation and examination of existing data. JH&P focuses on point source pollution, related health impacts, environmental control and remediation technology. JH&P also has an interest in ambient and indoor pollution. Pollutants of particular interest include heavy metals, pesticides, radionuclides, dioxins, polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds (VOCs), air particulates (PM10 and PM2.5), and other severe and persistent toxins. JH&P emphasizes work relating directly to low and middle-income countries, however relevant work relating to high-income countries will be considered on a case-by-case basis.
