Spatial distribution of polybrominated diphenyl ethers and polychlorinated dibenzo-p-dioxins and dibenzofurans in soil and combusted residue at Guiyu, an electronic waste recycling site in southeast
TLDR
The crude processing of e-waste has become one of the major contributors of PBDEs and PCDD/Fs to the terrestrial environment and acid leaching and open burning emitted the highest concentrations. Expand
Accumulation of lead, zinc, copper and cadmium by 12 wetland plant species thriving in metal-contaminated sites in China.
The concentrations of lead, zinc, copper and cadmium accumulated by 12 emergent-rooted wetland plant species including different populations of Leersia hexandra, Juncus effusus and EquisetumExpand
Polycyclic aromatic hydrocarbons (PAHs) in urban surface dust of Guangzhou, China: Status, sources and human health risk assessment.

  • Environmental Science, Medicine
  • The Science of the total environment
  • 1 October 2011
TLDR
Ninety-six urban surface dust samples collected from Guangzhou, a typical urban center in South China, were analyzed for PAHs, and four hotspots with highest ∑PAHs were identified via kriging prediction mapping, representing the highly-urbanized regions. Expand
Distributions and concentrations of PAHs in Hong Kong soils.
TLDR
The values of PAHs isomer indicated that biomass burning might be the major origin ofPAHs in rural soils, but vehicular emission around the heavy traffic roads might contribute to the soil PAHS in urban areas. Expand
Bisphenol A (BPA) in China: a review of sources, environmental levels, and potential human health impacts.
TLDR
Due to potential human health risks from long-term exposure to BPA, body burden of the contaminant should be monitored. Expand
Electronic waste management approaches: an overview.
TLDR
An overview of toxic substances present in e-waste, their potential environmental and human health impacts together with management strategies currently being used in certain countries are presented. Expand
Environmental mercury contamination in China: sources and impacts.
  • L. Zhang, M. Wong
  • Environmental Science, Medicine
  • Environment international
  • 2007
TLDR
There seems to be an urgent need to identify the sources of Hg, speciation and concentrations in different ecological compartments, which may lead to high body loadings in human beings. Expand
Residues of organochlorine pesticides in Hong Kong soils.
TLDR
The results presented that HCH and 5 Stockholm Convention pesticides were detected in Hong Kong soils although the detectable ratio varies to a great extent and close correlations of pH(KCl) and total organic carbon (TOC) with HCH indicated an effect on the residues of HCH caused by these two soils properties, but such relationships were not found with DDT or other OCPs. Expand
The role of arbuscular mycorrhiza in zinc uptake by red clover growing in a calcareous soil spiked with various quantities of zinc.
TLDR
The data demonstrate that mycorrhizal hyphae could absorb Zn directly from the soil and then transfer it to the plant roots, thus confirming the critical Zn application level found previously. Expand
Metal Concentrations of Common Freshwater and Marine Fish from the Pearl River Delta, South China
TLDR
There appears to be potential threat to local people from Hg contamination because of the high marine fish consumption rate and daily intake through fish consumption of these metals were compared with the Provisional Tolerable Weekly Intake proposed by the Joint Food and Agriculture Organization/World Health Organization Expert Committee on Food Additives.
