The distribution, sources, and potential risks of polychlorinated biphenyl （PCB） contamination in the rivers of Shanghai, China were investigated. Fourteen PCB congeners in surface waters and sediments, which were collected from 53 sampling sites, were quantified by gas chromatography-mass spectrometer （GC-MS）. The total concentrations of PCBs in the dissolved phase, in particulates, and in sediments ranged from not detected （nd） to 34.8 ng.L^-1, from 0.76 to 39.71 ng.L^-1, and from 1.46 to 46.11 ng.g^-1 （dry weight, dw）, respectively. The corresponding WHO toxic equivalents （TEQs） of dioxin-like polychlorinated biphenyls （dl-PCBs） ranged between nd-1135.63 pg TEQ-L^-1, 0.02-605.94 pg TEQ.L^-1, and 0.05-432.12 pg TEQ-g^-1 dw, respectively. Thepenta-CBs, especially PCB 118 and PCB 105, were the dominant congeners in all samples. Principle Component Analysis （PCA） indicated that the PCBs were mainly influenced by a historical accumulation of commercial PCB products, the burning of house coal, and emissions from municipal solid waste incineration （MSWI） and secondary metallurgy industries. The center of Shanghai was significantly affected by PCB contamination, followed by the industrial parklands and suburban towns, while the farmland of Chongming Island was the least affected area. Adverse biological and health effects would be likely in the central urban areas, industrial parks, and residential towns of Shanghai.

One major goal of mesh parameterization is to minimize the conformal distortion. Measured boundary parameteri-zations focus on lowering the distortion by setting the boundary free with the help of distance from a center vertex to all the boundary vertices. Hence these parameterizations strongly depend on the determination of the center vertex. In this paper,we introduce two methods to determine the center vertex automatically. Both of them can be used as necessary supplements to the existing measured boundary methods to minimize the common artifacts as a result of the obscure choice of the center vertex. In addition,we propose a simple and fast measured boundary parameterization method based on the Poisson's equation. Our new approach generates less conformal distortion than the fixed boundary methods. It also generates more regular domain boundaries than other measured boundary methods. Moreover,it offers a good tradeoff between computation costs and conformal distortion compared with the fast and robust angle based flattening (ABF++).
