The acute toxicity of herbicide atrazine to a species of green algae Scenedesmus obliquus, a species colorless heterotrophic flagellate Bodo saltans and two species of ciliates Tetrahymena priformis and Oxytricha saprobia was examined in laboratory tests. The results showed that the acute toxicity of atrazine to S. obliquus, B. saltans, T. priformis and C. pyrenoidosa was high. The median effective...
South Taihu Lake used to get less attention in terms of environmental pollution study in the past. Sediment and fish samples were collected from South Taihu Lake in 2009. Heavy metals were measured for both types of samples and potential health risks were evaluated. Concentration of Cu, Zn, Cr and Ni were determined for sediments samples, and Cu, Zn, Ni, Fe and Mn were determined for fish samples...
Study on microbial community structure and diversity in freshwater is important for exploiting the relationship of microbial community and its habitats, predicting and monitoring the ecological changing of contaminated water habitat. The retrieval of 16SrDNA genes directly from the environment has made it possible to estimate the phylogenetic diversity of a natural bacterial community without preceding...
