In order to study the sources and concentrations of heavy metals in atmospheric PM₁₀, a total of 144 samples were collected in two areas of Handan, China. The metal contents of Mn, Co, Ni, Cu, Cd, and Pb in the sample were analysed by inductively coupled plasma mass spectrometry. Contamination characteristics and sources were analysed by the geo-accumulation index and the enrichment factor method...
Land-use/land-cover change (LUCC) is an important issue of research into global change. To identify the spatiotemporal change and the driving mechanism of land use at the regional scale is of great significance to environmental preservation and economic development in the whole locality. In order to analyze the spatiotemporal change of land cover in Fuxian Lake watershed for the last four decades,...
Interspecies competition is considered an important effector of community structure in ecosystems. Interspecies interactions may change due to changing environmental factors, including exogenous organic pollutants. In this paper, we measured the change in population density, based on the logistical growth model, of Microcystis aeruginosa and Scenedesmus obliquus when they were cultivated in single-species...
