“…A similar phenomenon was observed in Mexico estuaries (Zou et al 1996) and many mesotrophic lakes (Kaiserli et al 2002;Penn et al 1995); hence, it could be concluded that Hua-jia-chi pond was in a mesotrophic transition state at present and its sediment was calcic (cf. Bostrom 1988;Gonsiorczyk et al 1998).…”

Phosphorus (P) fractions and the effect of phytoremediation on nitrogen and phosphorus removal from eutrophicated water and release from sediment were investigated in the eco-remediation experiment enclosures installed in the Hua-jia-chi pond (Hangzhou city, Zhejiang province, China). The main P fraction in the sediment was inorganic phosphorus (IP). For the mesotrophic sediments, IP mainly consisted of HCl-extractable P (Ca-P). The annual-average concentration of total nitrogen (TN), total phosphorus (TP) in water and the content of TN, TP in different vertical depth of sediment in the experiment enclosures with hydrophyte were always much lower than those in the control enclosure without hydrophyte and those outside of experiment enclosures. It is suggested that phytoremediation was an effective technology for N and P removal from eutrophicated water and release from sediment.

“…Serious blue-green algae water blooms have been frequently occurring in recent years (Zhang and Qin, 2001a). The pollutants in Taihu Lake include nitrogen, phosphorus, heavy metals, some persistent organic pollutants, such as DDT and HCH (Zou et al, 1996;Dai and Sun, 2001;Zhang and Qu, 2001b;Yuan et al, 2002;Wang et al, 2003;Feng et al, 2003). However, study on PCDD/Fs and PCBs in the lake is scarce.…”

Sediments at 16 sites and muscles of four aquatic species collected in Taihu Lake were analyzed for polychlorinated dibenzo-p-dioxins, dibenzofurans (PCDD/Fs) and polychlorinated biphenyls (PCBs) by HRGC/HRMS. The concentrations of total PCDD/Fs, PCBs and WHO-TEQ were 120.1-1315.1 pg/g dw, 889.7-29747.8 pg/g dw, and 0.83-17.72 pg TEQ/g dw, respectively in sediments; and those in muscles were 5.49-35.84 pg/g ww, 1517.10-27647.98 pg/g ww, and 0.52-3.83 pg TEQ/g ww respectively. The concentrations of PCDD/Fs and PCBs in the sediments were decreasing gradually along the water flow. The pollution levels were compared with other studies and the possible sources were discussed.

“…This paper discusses the results from Taihu in the first of these areas, the lowland Jiangsu region in eastern China. Previous studies on Taihu have discussed the impacts of direct inputs of pollutants from municipal and industrial wastewater and domestic sewage (e.g., Zou et al 1996;Shen et al 2000;Yu and Yang 2001;Dickman et al 2001;Qu et al 2001). Here, we focus on the identification of changes in input of pollutants to the lake from atmospheric deposition.…”

As part of a study using lake sediments to determine the extent and causes of human impacts to lakes along an east-west transect following the Yangtse River, sediment cores were taken from Taihu in eastern China. Previous studies have focussed on the impacts of direct inputs of pollutants from municipal and industrial wastewater but little work has been undertaken on trends in atmospheric deposition from the many industrial sources surrounding the lake. Analysis of the Taihu sediment cores for atmospheric pollutant indicators such as trace metals, magnetic parameters and spheroidal carbonaceous particles (SCPs) show the lake has become increasingly contaminated over the last 40-50 years. Sediment levels of atmospherically deposited pollutants are currently similar to some of the more contaminated lakes in Europe. Further, sediment nitrogen, phosphorus and geochemical analyses confirm the dramatic increase in eutrophication at the site and periods of recent soil erosion in the catchment.
