“…In China, rapidly increasing amount of E-waste from both domestic generation and illegal imports (UNEP, 2005;Widmer et al, 2005) should be mentioned. Since 1990s, a large amount of E-waste have been dismantled in Taizhou, Zhejiang Province, which is a well-known E-waste recycling centre in southeast China (Hicks et al, 2005;Zhao et al, 2006Zhao et al, , 2007. Hundreds of small and open specialized E-waste recycling shelters or yards appear in this area.…”

“…Recent works have studied the contamination of persistent organic pollutants such as polychlorinated biphenyls and organochlorine pesticides (Zhao et al, , 2007 in local food such as rice seeds, hen eggs, and silver carp muscle. To our knowledge, very few studies have investigated the heavy metal contents in crops collected from E-waste dismantling areas and conducted the corresponding risk assessment.…”

Very few studies have investigated the heavy metal contents in rice samples from a typical E-waste recycling area. In this study, 10 heavy metals (As, Ba, Cd, Co, Cr, Cu, Hg, Mn, Ni and Pb) in 13 polished rice and relevant hull samples, six relevant paddy soil samples were investigated. The geometric mean concentrations of Cd, Cu and Hg in soil samples were 1.19, 9.98 and 0.32 lg g À1 , respectively, which were 4.0, 2.0 and 1.1-folds of the maximum allowable concentration (MAC) (0.30, 50.00, 0.30 lg g À1 , respectively) for Chinese agricultural soils. The analyzed metal concentrations were significantly different between rice and relevant hull except for As, Cd and Hg (p < 0.05). All metal concentrations, except for Co, in rice hull were higher than those in polished rice. The geometric mean of Pb in polished rice reached 0.69 lg g À1 , which was 3.5-folds higher than the MAC (0.20 lg g À1 ) by the safety criteria for milled rice. Cd contents in 31% of the rice samples exceeded the national MAC (0.20 lg g À1 ), and the arithmetic mean also slightly exceeded national MAC. In addition, Cd and Pb contents in local rice were much higher than commercial rice samples examined in this work and previous studies. Comparing the tolerable daily intakes given by FAO/WHO with the mean estimated daily intakes; Pb daily intake through rice consumption in this area was 3.7 lg day À1 kg À1 body weight (bw), which already exceeded the FAO tolerable daily intake, and the Cd daily intake (0.7 lg day À1 kg À1 bw) through rice had already taken up 70% of the total tolerable daily intake (1 lg day À1 kg À1 bw). The daily intake of Hg and As through rice was much lower than the tolerable daily intakes, but bioaccumulation of Hg through the food chain and intake of As from other food stuff should also be of concern.

“…Most of human milk samples were collected from eastern China during the period 1987-2005. HCB could be detected in all the studies, but HCB levels in various areas ranged widely (Kunisue et al, 2004;Zhao et al, 2007). Human milk from some cities such as Changsha, Shijiazhuang had high HCB concentrations (Cao et al, 2000;Sun et al, 2005).…”

a b s t r a c t a r t i c l e i n f oThis article summarizes the published scientific data on sources, levels and human exposure of hexachlorobenzene (HCB) in China. Potential sources of unintended HCB emission were assessed by production information, emission factors and environmental policies. HCB was observed in various environmental compartments in China. HCB levels increased from South China to North China in most of environmental compartments (air, soil and mussel). Some hotspots were identified near the factories producing and using HCB. In terms of spatial distribution, HCB concentrations in air and shellfish showed much variation, which indicated some primary emission sources in China. HCB levels in air and human milk in China were relatively higher than those in other countries, but HCB levels in other compartments were similar to those in Europe and other countries in Eastern Asia. In the limited studies on temporal trends of HCB levels in China, HCB concentrations in air, sediment, fish and human milk did not show a consistent downward trend. Although HCB levels in food and human milk does not pose a health risk in China at present, long-term exposure to HCB should not be overlooked.

“…Furthermore, human milk collected from TZ contained much higher concentrations of total PCBs than those from GY (Xing et al, 2009). In addition, TZ is the largest center for dismantling obsolete transformers and capacitors in China (Zhao et al, 2007). Unwanted electric power electromotors, capacitors, transformers, and their components are common items of e-waste processed in TZ but are scarce in GY .…”
