Chemical compositions of wet precipitation and anthropogenic influences at a developing urban site in southeastern China
A comprehensive study on the chemical compositions of wet precipitation was carried out from January 2004 to December 2004 in Jinhua, southeastern China's Zhejiang Province. All samples were analyzed
Antimony pollution in China.
The local environments around Sb mining and smelting areas were seriously contaminated and plants growing in these contaminated soils accumulated high levels of Sb and exceeded the tolerable concentration, thus threatening the health of local inhabitants.
Impact of deashing treatment on biochar structural properties and potential sorption mechanisms of phenanthrene.
Results of this work could help to better understand the impact of minerals, bulk/surface polarity, and sorption domain arrangement of biochars on their HOCs sorption and predict the fate of Hocs in soils after biochar application.
The influence of dissolved and surface-bound humic acid on the toxicity of TiO₂ nanoparticles to Chlorella sp.
Co-precipitation experiment and transmission electron microscopy observation revealed that both dissolved and nanoparticle surface-bound HA prevented the adhesion of nano-TiO₂ to the algal cells due to the increased electrosteric repulsion, which could account for the HA-mitigated nanotoxicity.
Spatial distribution and pollution assessment of heavy metals in urban soils from southwest China.
Spatial distribution maps indicated that Pb, Zn, and Cu were mainly controlled by anthropogenic activities, whereas As could be mainly accounted for by soil parent materials.
Characteristics of organic phosphorus fractions in different trophic sediments of lakes from the middle and lower reaches of Yangtze River region and Southwestern Plateau, China.
In this study, the characteristics of organic phosphorus (Po) fractions in sediments of six lakes from the middle and lower reaches of Yangtze River region and Southwestern China Plateau, China were
Phosphorus fractions and phosphate sorption characteristics in relation to the sediment compositions of shallow lakes in the middle and lower reaches of Yangtze River region, China.
The phosphorus fractions and phosphate sorption characteristics of sediments in shallow lakes from the middle and lower reaches of Yangtze River region in China were investigated and it was found that phosphorus was higher in the sediments of eutrophic lakes than in mesotrophic lakes.
Health risk associated with dietary co-exposure to high levels of antimony and arsenic in the world's largest antimony mine area.
The preliminary results suggested that dietary exposures to Sb, rather than As, was the dominant health risk to local residents, and the adverse effects of As levels on the health of residents still can not be ignored since the elevated As concentrations in human hair have reached the critical level for health risks.
Fluorescence characterization of dissolved organic matter in an urban river and its complexation with Hg(II)
Abstract Dissolved organic matter (DOM) in the Nanming River, an urban river in Guiyang City in SW China, and its complexation behavior with Hg(II) were investigated using fluorescence spectroscopy
Effects of biological activity, light, temperature and oxygen on phosphorus release processes at the sediment and water interface of Taihu Lake, China.
The results show that organisms at the sediment and water interface can stimulate P release from sediments, and their metabolism can alter the surrounding micro-environmental conditions, which aids the understanding of P biogeochemical cycling at the interface and its relationship with eutrophication in shallow lakes.
