1Arsenobetaine and thio-arsenic species in marine macroalgae and herbivorous animals: Accumulated through trophic transfer or produced in situ?显示文摘Arsenobetaine(AB) and thio-arsenoribosides were measured in common macroalgae species(8 phaeophyta, 4 rhodophyta and 2 chlorphyta), along the Australian south east coast line. As well, arsenic species profiles were measured for two common marine herbivores, the sea urchin Centrostephanus rodgersii and the fish Odax cyanomelas that graze on these macroalgae to understand if trophic transfer of these species would account for their presence in marine herbivores. AB was found in seven of the fourteen macroalgae species investigated but does not contributed significantly to any of the macroalgae arsenic content(0.01-1.2 μg/g). AB was found in only two of the brown macroalgae and all the red and green macroalgae(with the exception of Corallina officinalis). Thio-arsenic species were found sporadically, but not in high concentrations in any of the macroalgae investigated.AB present in macroalgae is likely to be associated with epiphytic organisms while thio-arsenoribosides are likely to be produced by decaying parts of damaged macroalgae.A laboratory feeding experiment in which the herbivorous gastropod, Austrocochlea constricta, was fed macroalgae containing thio-arsenoribosides for a 24 hr period every three days showed that these are readily accumulated over a short period. Thio-arsenoribosides in herbivores are therefore probably obtained through trophic transfer. Some AB is also obtained through trophic transfer; however, the presence of trimethylated arsonioribosides,a hypothesized precursor of AB formation in herbivores, suggests that some AB is produced within herbivores from the transformation of arsenoribosides accumulated from their diet.Simon Foster William Maher 2016Journal of Environmental Sciences2016,28,11:10

3Evaluation of the ability of arsenic species to traverse cell membranes by simple diffusion using octanol-water and liposome-water partition coefficients显示文摘在生活有机体的砷新陈代谢依赖于不同的砷种类的能力穿越生物的膜。简单散开提供其他的流入和流出线路给能在房间增加为新陈代谢可得到的砷的数量的调停的运输机制。使用 octanol 水和 liposome 水分区系数,砷的酸的能力,砷酸盐, methylarsonate, dimethylarsinate, thio-methylarsonate, thio-dimethylarsinic 酸, arsenotriglutathione 和通过房间膜的类脂化合物 bilayer 扩散的 monomethylarsonic diglutathione 被调查。砷种类的分子的建模被用来解释结果。有砷酸盐, methylarsonate 和 thio-methylarsonate 的异常的所有砷种类能通过 liposomes 的类脂化合物 bilayer 扩散,与在 0.04 和 0.13 之间的 liposome 水分区系数。三价的砷种类和 thio 五价的砷种类显示出更高的分区系数,建议他们能容易穿越由被动简单散开的房间膜。与含氧五价的砷种类相比给这些的更高的毒性种类,这研究提供支持与人的暴露联系到的风险的证据三价并且 thio 砷种类。Teresa Chavez-Capilla William Maher Tamsin Kelly Simon Foster 2016Journal of Environmental Sciences2016,28,11:4
