“…Concentration of Pb, Cd, Cr and Ni in human placenta in women living near Guiyu in China revealed 41.6% women has Pd levels exceeding 500 ng/g wt compared to 24.4% women in control site (Guo et al , 2010). Similar result was found for Cd near an e-waste recycling site in China where unrinary Cd levels were found to be significantly high (0.72 µg/L) compared to the control site (0.27 µg/L) (Wang et al 2011a).…”

E-waste: a problem or an opportunity? Review of issues, challenges and solutions in Asian countries

Safe management of electronic and electrical waste (e-waste/ WEEE) is becoming a major problem in many countries around the world. In particular, developing countries face number of issues with the generation, transboundary movement and management of e-waste. It is estimated that the world generates around 20-50 million tonnes of e-waste annually, most of it from Asian countries. Improper handling of ewaste can cause harm to the environment and human health due to its toxic components. Several countries around the world are now struggling to deal with this emerging threat. Although the current emphasis is on end-of-life management of ewaste activities such as reuse, servicing, remanufacturing, recycling and disposal; upstream reduction of e-waste generation through green design and cleaner production is gaining much attention. Environmentally sound management (ESM) of e-waste in developing countries is absent or very limited. Transboundary movement of e-waste is a major issue in the region. Dealing with the informal recycling sector is a complex social and environmental issue. There are significant numbers of such challenges faced by these countries in achieving ESM of e-waste. This paper aims to present a review of challenges and issues faced by Asian countries in managing their e-waste in a sustainable way.

“…The percentages of blood lead concentration exceeding 10 mg/dL in Guiyu children were 81.83% (2004) [2,16,17]. Cadmium levels in human and environmental samples from Guiyu are also higher than those in other places without e-waste recycling [7,[18][19][20][21]. Similar to the case of PBDEs, lead and cadmium may also relate to hormone alteration.…”

Informal electronic waste (e-waste) recycling results in serious environmental pollution of polybrominated diphenyl ethers (PBDEs) and heavy metals. This study explored whether there is an association between PBDEs, heavy metal and key growth-and development-related hormones in children from Guiyu, an e-waste area in southern China. We quantified eight PBDE congeners using gas chromatographic mass spectrometry, lead and cadmium utilizing graphite furnace atomic absorption spectrometry, three thyroids with radioimmunoassay and two types of growth hormones by an enzyme-linked immune-sorbent assay (ELISA) in 162 children, 4 to 6 years old, from Guiyu. In blood, median total PBDE was 189.99 ng/g lipid. Lead and cadmium concentrations in blood averaged 14.53¡4.85 mg dL 21 and 0.77¡0.35 mg L 21 , respectively. Spearman partial correlation analysis illustrated that lead was positively correlated with BDE153 and BDE183. Thyroid-stimulating hormone (TSH) was positively correlated with almost all PBDE congeners and negatively correlated with insulin-like growth factor binding protein-3 (IGFBP-3), whereas free triiodothyronine (FT3) and free thyroxine (FT4) were negatively correlated with BDE154. However, no correlation between the hormones and blood lead or cadmium levels was found in this study. Adjusted multiple linear regression analysis showed that total PBDEs was negatively associated with FT3 and positively associated with TSH. Notably, FT4 was positively correlated with FT3, house functions as a workshop, and father's work involved in e-waste recycling and negatively correlated with vitamin consumptions.

“…119 Pregnant women near a WEEE recycling area were concluded to have higher body burdens of PBDE, PCDD/F, and PCB compounds (on the basis of measurement of maternal serum and cord blood) compared with the reference group results. 120 Guo et al 121 measured the concentration of several heavy metals in placentas collected from a WEEE recycling area and a reference area and found a correlation between placenta Pb levels and residence in the recycling area.…”

Environmental Issues and Management Strategies for Waste Electronic and Electrical Equipment

Issues surrounding the impact and management of discarded or waste electronic and electrical equipment (WEEE) have received increasing attention in recent years. This attention stems from the growing quantity and diversity of electronic and electrical equipment (EEE) used by modern society, the increasingly rapid turnover of EEE with the accompanying burden on the waste stream, and the occurrence of toxic chemicals in many EEE components that can pose a risk to human and environmental health if improperly managed. In addition, public awareness of the WEEE or "e-waste" dilemma has grown in light of popular press features on events such as the transition to digital television and the exportation of WEEE from the United States and other developed countries to Africa, China, and India, where WEEE has often not been managed in a safe manner (e.g., processed with proper safety precautions, disposed of in a sanitary landfill, combusted with proper air quality procedures). This paper critically reviews current published information on the subject of WEEE. The definition, magnitude, and characteristics of this waste stream are summarized, including a detailed review of the chemicals of concern associated with different components and how this has changed and continues to evolve over time. Current and evolving management practices are described (e.g., reuse, recycling, incineration, landfilling). This review discusses the role of regulation and policies developed by governments, institutions, and product manufacturers and how these initiatives are shaping current and future management practices.
