In this study we investigated Sb and arsenic (As) distributions in indoor dust from 13 e-waste recycling villages in Guiyu Guangdong Province southeastern China. Results revealed significantly elevated concentrations of Sb (6.1–232 mg/kg) in dust within all villages which were 3.9–147 times higher than those from the non e-waste sites indicating e-waste recycling was an important source of
With the development of technologies and the change of consumer attitudes the amount of waste electrical and electronic equipment (WEEE) is increasing annually. As the core part of WEEE the waste printed circuit board (WPCB) is a dangerous waste but at the same time a rich resource for various kinds of materials. In this work various WPCB treatment methods as well as WPCB recycling

Analysis of 10 types of locally produced staple foods (including meat fish and eggs) provided estimates of dietary intakes of polybrominated diphenyl ethers (PBDEs) for residents of areas of Taizhou City (Zhejiang Province Eastern China) which are long-established centers of rudimentary "e-waste" recycling. Average ∑PBDE concentrations in chicken meat eggs and liver and duck meat
Due to economic and societal reasons informal activities including open burning backyard recycling and landfill are still the prevailing methods used for electronic waste treatment in developing countries. Great efforts have been made especially in China to promote formal approaches for electronic waste management by enacting laws developing green recycling technologies initiating pilot
1. Introduction. Environmental contamination by e-waste recycling is an emerging global issue (Robinson 2009) 2006 the world s production of e-waste was estimated at 20–50 million tonnes per year (UNEP 2006) and it is growing at around 4 per year (Focus 2005) is estimated that 50–80 of the e-waste from US Europe and other areas of the world is legally or illegally imported to
The increasing use of electrical and electronic equipment leads to a huge generation of electronic waste (e-waste). It is the fastest growing waste stream in the world. Almost all electrical and electronic equipment contain printed circuit boards as an essential part. Improper handling of these electronic wastes could bring serious risk to human health and the environment.
Stage of the electronic waste dismantling and processing distribution as well as a part of the small and medium recycling enterprises extracted to recover valuable metals the WPCBs can be sent directly to the Corresponding author. Tel. fax .
