Based on the analysis of 210Pb radioactivity of the cores collected from intertidal wetlands of Luoyang River and Jinjiang River in 2008, this paper analyzed the vertical distribution and change characters of 210Pbex, and discussed the variation and infection factors of deposition rates and sedimentation flux. The results showed that both of the cores were affected to a certain extent, such as bioturbation,...
Effect of nutrient concentration of overlying water on nitrogen and phosphor release from sediment in Lake Baiyangdian was studied in this paper. The results indicated that nutrient levels of overlying water impacted the release rate significantly. The average release rates were negatively correlated to the nutrient levels of overlying water. The release curves of absolute amount for total nitrogen...
