The Songhua River Basin, the third biggest basin in China, is one of the most important commodity grain bases in China. Agricultural nonpoint source pollution has been listed as one of the leading sources of pollution in rivers and streams in this basin. We examined the residues of herbicides including atrazine and acetochlor in riparian soils and sediment samples from 248 stations throughout this...
The adsorption and desorption of carbendazim and cadmium (Cd) in soils (burozem and phaeozem) typically distributed in northeastern China were investigated at two different temperatures, 25 and 40°C. The effects of interaction between carbendazim and Cd on their adsorption and desorption were also discussed. The results showed that the adsorption of carbendazim was exothermic with ΔH Θ values...
The southern Lake Tai area is an important agricultural area distributed with 500,000 ha of paddy soils. Based on the current soil phosphorus status, it is predicted that phosphorus in agricultural runoff from paddy fields is now one of the most dangerous threats to the quality of water in Lake Tai and the application of phosphorus fertilizers should be controlled. Phosphorus adsorption maxima based...
