Health Risks of Polybrominated Diphenyl Ethers (PBDEs) and Metals at Informal Electronic Waste Recycling Sites.

Concerns about the adverse public health consequences of informal electronic waste (-waste) recycling are increasing. This study adopted a cross-sectional study design to gain insights into health risks (cancer and non-cancer risks) associated with exposure to -waste chemicals among informal -waste workers via three main routes: Dermal contact, ingestion, and inhalation. The -waste chemicals (PBDE and metals) were measured in the dust and top soils at -waste sites (burning, dismantling, and repair sites).

Hydrophobic Organic Pollutants in Soils and Dusts at Electronic Waste Recycling Sites: Occurrence and Possible Impacts of Polybrominated Diphenyl Ethers.

Concerns about the adverse consequences of informal electronic waste (e-waste) recycling is increasing, because e-waste contains some hazardous substances such as polybrominated diphenyl ethers (PBDEs) which is used as flame retardants in electronics. There is dearth of information on the concentrations of PBDEs and the pattern of distribution at the various e-waste recycling sites in Nigeria. This study therefore measured the concentrations of 13 PBDE congeners, in top soils (0⁻10 cm) and in various dust samples from different e-waste recycling sites (burning, dismantling, repair).

Impact of informal electronic waste recycling on metal concentrations in soils and dusts.

Electronic and electrical equipment contains over 1000 different substances, including metals. During informal e-waste recycling some of these substances such as metals, are released into the environment causing environmental pollution. This study assessed the impact of different informal e-waste recycling activities (burning, dismantling, and repairing) on metal concentrations in top soils and various dust.

Health Risks Awareness of Electronic Waste Workers in the Informal Sector in Nigeria.

Insight into the health risk awareness levels of e-waste workers is important as it may offer opportunities for better e-waste recycling management strategies to reduce the health effects of informal e-waste recycling. Therefore, this study assessed the knowledge, attitude, and practices associated with occupational health risk awareness of e-waste workers compared with a control group (butchers) in the informal sector in Nigeria. A cross-sectional study was used to assess health risk awareness of 279 e-waste workers (repairers and dismantlers) and 221 butchers from the informal sector in three locations in Nigeria in 2015.

Prevalence and injury patterns among electronic waste workers in the informal sector in Nigeria.

Background: Despite the large volume of e-waste recycled informally, the prevalence of work-related injuries among e-waste workers is unknown. Therefore, this study assessed the prevalence, patterns and factors associated with occupational injuries among e-waste workers in the informal sector in Nigeria.

Methods: This cross-sectional study adopted a multistage sampling method to select 279 respondents from three cities (Ibadan, Lagos and Aba) in Nigeria.

Micronutrient powder distribution through Maternal, Neonatal and Child Health Weeks in Nigeria: process evaluation of feasibility and use.

Objective: To determine the feasibility of distributing micronutrient powders (MNP) for home fortification during biannual Maternal, Neonatal and Child Health Week (MNCHW) events, as a strategy to improve young child nutrition.

Design: We evaluated the coverage, delivery, use and adherence of MNP, and associated behaviour change communication (BCC) materials and social mobilization, through cross-sectional surveys of caregivers attending health-service distribution events and health workers involved in MNP distribution, facility-based observations of MNP distribution activities and a repeated survey of caregivers in their homes who received MNP for their child.

Setting: Four Local Government Areas in Benue State, Nigeria.
