Yunfu pyrite deposit bearing thallium (Tl) with proven reserves of three million tons' Tl in Guangdong Province, China has been extensively exploited since 1970. This study investigated contamination levels of Tl and other trace metals in ecosystem such as soils, surface waters, vegetables and crops in the area near the deposit. Results show that Tl in these samples nearby has greatly enriched and...
The distribution, profile, sources, and impacts of polycyclic aromatic hydrocarbon (PAHs) in oilfield soils were investigated. The concentrations and distribution of PAHs in soils from five sites (named as S1, S2, S3, S4 and S5) showed different levels of PAHs. The concentrations of total PAHs in the soils ranged from 1340 to 82393 ng/g. The profiles of different number of aromatic rings in each of...
Samples of groundwater, leachates, surface water and soils were collected from 22 sites in the Municipal solid waste landfill area in Wuhan, Central China. Sixteen phthalate esters (PAEs) were detected by gas chromatography (GC). The results showed that there were one or several PAEs in all the samples and the concentrations of total PAEs in groundwater, leachates, surface water, and soils were 0...
