Pollution Character of Heavy Metals in River Sediments from Small Towns,Shanghai

Environmental Sciences (2006)

Wei Liu Zhenlou Chen XU Shi-yuan

By selected three small towns,we studied the pollution character of heavy metals in sediments.Results show that the content of sediments-Zn is between 3.11 g/kg and 3.74g/kg,which is heavily excess the criterion of farming fertilized by sullage.The Zn-pollution of sediments has been a territorial and heavily pollution question of small towns,the content of sediments-Pb is between 0.03 g/kg and 1.00g/kg,And that of sediments-Cu is between 0.07g/kg and 0.20g/kg.The river sediments has also been polluted by Pb and Cu.To the diversity-region,light-toxicity metals(Fe,Mn,Zn) is less than heavy-toxicity metals(Pb,Cu,Cr).The river sediments from small towns can not be fertilized to the farmlands. By analyzed the relativity of TP-metals(Fe,Cr,Cu,Mn,Pb,Zn) and that of Fe-metals(Fe,Cr,Cu,Mn,Pb,Zn),we can conclude living sewage form small towns is a source of metals in sediments.Street-dust is an important source of sediments-Pb through surface-eroded by living-sewage.

Design and realization of technical service system for urban blank-odor river treatment based on Web technology

Yulan Hou Honglin Li Jun Wang Zhihong Li Zhenlou Chen

With the rapid development of Chinese urbanization and industrialization, it has become an increasingly pressing problem to alleviate the situation of blackening and stink of the urban rivers. In the requirement of controlling black-odor river, this research was operated with the support of the National Key Water Program during the 11th Five-Year Plan Period. In this study, the commonness technical network service system of urban black-odor river treatment is designed and developed, using B/S structure model and based on the WebGIS technology and database technology. The service system can realize three functions of technical browse and query, technique service and performance evaluation, and provide systematic and effective decision support basis for the treatment of Chinese urban black and stinking river.

[Heavy metal content and ecological risk warning assessment of vegetable soils in Chongming Island, Shanghai City].

PubMed (2007)

Jun Wang Zhenlou Chen Chu Wang Ming-Wu Ye Jing Yu Shen

In order to determine the content of copper (Cu), lead (Pb), chromium (Cr), zinc (Zn) and cadmium (Cd) in vegetable field, soil samples were collected from three towns of Chongming Island, an important ecotypic island of Shanghai City. The average content of Cu, Zn, Pb, Cr and Cd in vegetable soil of the three towns is 29.2 mg x kg(-1), 91.2 mg x kg(-1), 26.5 mg x kg(-1), 79.4 mg x kg(-1) and 0.222 mg x kg(-1), respectively. Except for the content of Cd exceeded the first grade of national soil standard (GB 15618-1995), the contents of the other four heavy metals were less than the first grade of the standard, and the content of heavy metals in this fireld met the request of heavy metal level to produce green foods (NY/T 391-2000). The contents of Cu, Pb, Cr, Zn and Cd in the vegetable soils are 24.3%, 24.4%, 22.9%, 18.8% and 65.7% higher than the background value of Shanghai, respectively. The result of ecological risk warning assessment showed that three sampling sites were medium warning situation, ten were light warning situation, eight were warning situation and one was no warning, in all the 23 sampling sites. The total situation of Chongming Island was light warning, and the I(ER) = 1.562. The order of ecological risk was Baozhen town (I(ER) = 1.799) > Chengqiaozhen town (I(ER) = 1.636) > Chenjiazhen (I(ER) = 1.368). The three towns were all light warning situation.

[Pollution characteristics and sources of polycyclic aromatic hydrocarbons in riparian soils along urban rivers of Wenzhou city].

PubMed (2012)

Jie-Cheng Zhou Chunjuan Bi Zhenlou Chen Lu Wang Shiyuan Xu

Twenty one riparian soil samples along Jiushanwai River and Shanxia River of Wenzhou city were collected in August 2010 to investigate the pollution characteristics of polycyclic aromatic hydrocarbons (PAHs). The samples were extracted by an accelerated solvent extractor (ASE), purified by a purification column and determined by GC-MS. Results showed that the total concentrations of PAHs in the riparian soils ranged from 60.7 ng x g(-1) to 3 871.3 ng x g(-1), and the concentrations of sigma PAHs in soils along the Shanxia River were significantly lower than the levels along Jiushanwai River. The dominant compounds were 2 to 3 rings in the riparian soils along both rivers, which in average accounted for 62.47% - 72.51% in sigma PAHs. Compared with the PAHs concentrations in soils of other areas in the world, the riparian soils of the studied rivers were moderately polluted by PAHs, but the concentrations of BaP in three soil samples were much higher than the soil standard value of the former Soviet Union, which should be paid more attention. Based on the ratios of Ant/(Ant + Phe) and Fla/(Fla + Pyr) and principal component analysis results, PAHs in riparian soils of the studied rivers were mainly derived from both the petroleum and combustion.

Pollution characteristics of PAHs in urban runoffs from main roads in urban area

Zhenlou Chen

Road runoff samples were collected from two typical roads in Shanghai and Wenzhou city during the rainy season in 2010.Sixteen PAHs in both dissolved and particulate phases in runoff samples were analyzed in order to characterize the PAHs dynamic transportation between two phases in runoff samples.PAH concentrations in runoff samples varied from 919.8 to 16711.6 ng · L-1.Dissolved PAH concentrations(4.9~1558.0 ng · L-1) were much lower than those in particulates(635.4~16624.0 ng · L-1).PAH concentration variations were investigated during three rainfall events,and the first flush effect(FFE) was not obvious during all of the runoff events.The occurrence of an FFE was dependent on multiple factors including pre-rain dry period,rainfall intensity,runoff volume,etc.Therefore,the initial runoff interception may not control the PAH contaminations in urban road runoff effectively.Partition coefficient(Kp) values changed from 2.3×104 to 2.5×106 L · kg-1.Kp values decreased with the total suspended solid(TSS) contents in the road runoff samples,which could be related to the particle size fractions in the runoff.

Nitrous oxide emissions in the Shanghai river network: implications for the effects of urban sewage and IPCC methodology

Global Change Biology (2013)

Zhongjie Yu Huanguang Deng Dongqi Wang Mingwu Ye Yongjie Tan

Global nitrogen (N) enrichment has resulted in increased nitrous oxide (N(2)O) emission that greatly contributes to climate change and stratospheric ozone destruction, but little is known about the N(2)O emissions from urban river networks receiving anthropogenic N inputs. We examined N(2)O saturation and emission in the Shanghai city river network, covering 6300 km(2), over 27 months. The overall mean saturation and emission from 87 locations was 770% and 1.91 mg N(2)O-N m(-2) d(-1), respectively. Nitrous oxide (N(2)O) saturation did not exhibit a clear seasonality, but the temporal pattern was co-regulated by both water temperature and N loadings. Rivers draining through urban and suburban areas receiving more sewage N inputs had higher N(2)O saturation and emission than those in rural areas. Regression analysis indicated that water ammonium (NH(4)(+)) and dissolved oxygen (DO) level had great control on N(2)O production and were better predictors of N(2)O emission in urban watershed. About 0.29 Gg N(2)O-N yr(-1) N(2)O was emitted from the Shanghai river network annually, which was about 131% of IPCC's prediction using default emission values. Given the rapid progress of global urbanization, more study efforts, particularly on nitrification and its N(2)O yielding, are needed to better quantify the role of urban rivers in global riverine N(2)O emission.
