Although the range of all metals studied in water samples did not exceed the National Water Quality Standard for Fisheries (GB 11607－89), relatively obvious contamination of Pb, and in particular Zn and As were found by the range in the samples of sediments and Anodonta woodiana.

虽然水样中各重金属均未超过国家渔业水质标准（GB1160789），但底泥和背角无齿蚌的结果显示出Pb，特别是Zn、As的污染比较明显。

In order to provide some scientific data for judging biological toxicity and bioavailability caused by heavy metals in sediments in Guilin, China, for the first time, the authors sampled sediments in different water areas in Guilin, and determined AVS by P-Amino dimethyl aniline dihydro chloride photometry through a set of acidification-ventilation-absorption AVS reaction unit, determined copper, lead, zinc, cadmium and nickel with tomic absorption spectrophotometry, mercury and arsenium with atomic fluorescence, and cipangopaludina cathayensis was selected as the tested species for bioavailability experiment.

首次以桂林水系沉积物为研究对象，通过酸化－吹气－吸收装置，用对氨基二甲基苯胺光度法测定沉积物中AVS含量，用原子吸收分光光度法测定SEM和间隙水中Cu、Pb、Zn、Cd、Ni含量，用原子荧光法测定Hg、As含量。

Structure analysis indicates that it crystallizes in triclinic, space group P1, a =9.554(3)A, b =10.4874(18) A, c =14.027(2) A,α=91.873(15)°,β=91.879(19)°,γ=92.86(2)°. The polymeric anion of [(CH3)4N]As3S5 consists of adjacent 1∞[AS3S5]- chains linked together into a 1∞ [As6S10]2- double chains through planar As2S2 rings . A relatively undistorted Ψ-AsS4 trigonal bipyramidal geometry is observed for the participating As atoms.

b=10.4874(18)，c=14.027(2)，α=91.873(15)°，β=91.879(19)°，γ=92.86(2)°。化合物[(CH_3)_4N]As_3S_5结构中聚合阴离子由邻近的~1_∞[As_3S_5]~-通过平面环As_2S_2连接形成~1_∞[As_6S_(10)]~(2-)链，这种链通过每第二个结构单元环状As_3S_3结构单元的As原子连接组成双链结构，其结构中可观察到赝三角锥配位的ψ-AsS_4。
