“…Tang and colleagues [37] reported very high levels (up to 3.4 mg/kg) of PAHs in agricultural soils in an e-waste recycling town in Taizhou area, China, where open burning of electronic components is practiced. More recently, Wang et al [38] found a predominance of phenanthrene and other low molecular weight PAHs in soil and high molecular weight PAHs such as fluoranthene, pyrene, and benzo[a]anthracene were bio-accumulated in vegetation near e-waste recycling sites in South China. They further estimated that the human daily intake of total and carcinogenic PAHs through vegetables in the area were 279 and 108 ng/kg/d, respectively.…”

h i g h l i g h t s• We simulated artisanal incineration of four component categories of cellphones.• We identified metals and organic chemicals in the resulting electronic waste ash.• We used USETox model to demonstrate potential ecotoxicity and human health impacts.• We identify targets for risk reduction for hazardous chemicals in cellphones. a r t i c l e i n f o b s t r a c tThe potential environmental and human health impacts of artisanal mining of electronic waste through open incineration were investigated. A market-representative set of cellphones was dismantled into four component categories-batteries, circuit boards, plastics and screens. The components were shredded, sieved and incinerated at 743-818• C. The concentrations of 17 metals were determined using U.S. EPA methods 6010C (inductively coupled plasma-atomic emission spectrometry; 6020A (inductively coupled plasma-mass spectrometry, or 7471B and 7470A (cold-vapor atomic absorption). EPA Method 8270 (gas chromatography/mass spectrometry) was used to identify polyaromatic hydrocarbon compounds and polybrominated diphenyl ethers. EPA Method 8082A was used to measure polychlorinated biphenyls and EPA Method 8290 was used for dioxin/furans in the residue ash. The life cycle assessment model USEtox ® was used to estimate impacts of the ash residue chemicals on human health and the ecosystem. Among metals, copper in printed circuit boards had the highest ecotoxicity impact (1610-1930 PAF m 3 /kg); Beryllium in plastics had the highest impact on producing non-cancer diseases (0.14-0.44 cases/kg of ash); and Nickel had the largest impact on producing cancers (0.093-0.35 cases/kg of ash). Among organic chemicals, dioxins from incinerated batteries produced the largest ecotoxicological impact (1.07E − 04 to 3.64E − 04 PAF m 3 /kg). Furans in incinerated batteries can generate the largest number of cancers and non-cancer diseases, representing 8.12E − 09 to 2.28E − 08 and 8.96E − 10 and 2.52E − 09 cases/kg of ash, respectively. The results reveal hazards of burning discarded cellphones to recover precious metals, and pinpoints opportunities for manufacturers to reduce toxic materials used in specific electronic components marketed globally.

“…In the first, pre-existing plants growing in urban and periurban areas, along roadsides, public parks or private gardens were sampled (Lodovici et al, 1998(Lodovici et al, , 2003Howsam et al, 2000;Lehndorff and Schwark, 2004;Singh and Verma, 2007;Wang et al, 2008;Lehndorff and Schwark, 2009;De Nicola et al, 2011b;Papa et al, 2012;Noth et al, 2013;Terzaghi et al, 2013). In the second scenario, the plants were sampled in the surroundings of disused or still working industrial sites (Sharma and Tripathi, 2009;Rodriguez et al, 2010Rodriguez et al, , 2012Wang et al, 2012). So, in both cases plants were exposed to air pollution for a long time, whereas we studied PAHs accumulation in evergreen shrubs transplanted to the experimental sites a couple of months before starting the sampling.…”

“…Therefore, the PRD, faced with the urgent task of balancing between sustainable socioeconomic development and environmental protection, is an ideal site for assessing anthropogenically derived contamination (Cai et al, 2007;Yang et al, 2010;Wang et al, 2011a). Previous studies have examined the occurrence of PAHs in soil of the PRD (Yu et al, 2007;Ma et al, 2008;Wang et al, 2012), but existing data are insufficient for an integrated assessment of urbanization-induced anthropogenic impacts on the environment. To achieve the above-mentioned objectives, soil samples were collected from a large number of locations grouped into six land-use types or four geographic regions ( Fig.…”
