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,...
The contents of some heavy metals (Cu, Zn, Pb, Cd and Cr) in dustfall samples from different city zones of Quanzhou were analyzed and their toxicity was assessed by toxicity characteristic leaching procedure (TCLP), which was developed by USEPA. The TCLP method is a currently recognized international method for evaluation of heavy metal pollution in dustfall. The available levels of Cu, Zn, Pb, Cd...
With the development of urbanization, the environmental quality of urban soil has been declining. Transport has become an important source of heavy metals in soil. To have a preliminary understanding of soil heavy metals pollution in the urban road, in this study, the contents of Cd, As, Pb, Zn, Cu, Ni and Cr in soil of urban road of Quanzhou City were analyzed and investigated to evaluate environmental...
