Organochlorine pesticides were detected and analyzed in surface water, bottom water and porewater from Honghu Lake, middle of China. The concentrations of total HCHs in surface water and bottom water were 3.52-5.68 ng/L and 3.77-6.86 ng/L respectively, and the concentrations of total DDTs were 0.39-2.38 ng/L and 0.91-6.05 ng/L respectively. Compared with the water quality of other regions, the concentrations...
Based on manganese content surpass the set standard seasonally in Jilihe reservoir's water, manganese content in the catchment basin of the river water, river sediment and the surrounding soil were analyzed, the environmental geochemical factors which impact manganese content were studied. According to the survey results, the reservoir water quality has obvious stratification: Dissolution of manganese...
The crude recycling of electronic waste (e-waste) in developing counties such as China has presented a significant environment pollution that affects both ecosystems and the people living within or near the main recycling areas in recent years. Although several studies have reported concentrations of trace metals and several typical toxic organic pollutants in various environmental compartments at...
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...
Metagenome is a fast developing cultivation independent technology, which is useful in addressing evolutionary and ecological relationship of microbial communities, also quite challenging to research function genes. Here we improved DNA extraction method and the DNA extracted is of high yield and allows direct 16S rDNA PCR amplification. we used the high-molecular-weight bacterial DNA to construct...
