标题:无机汞和甲基汞对虾虾直接和直接营养污染的同时实验研究
摘要:进行了一项实验研究,以调查无机汞(hg(II))或甲基汞(mehg)对小龙虾astacus Astacus的直接和直接加营养污染途径.直接暴露基于低污染条件,溶解相中分别为 300 和 30 Ng/l,在 20 摄氏度下持续 30 天.营养暴露基于每天食用亚洲蛤蜊 Corbicula Fluminea,之前在 40 天被污染类似的暴露条件.双壳贝类中的 Hg 浓度非常相似:Hg(II) 为 1,451 +/-287 Ng/g,Mehg 为 1,346 +/-143 Ng/g.在甲壳类动物中,在暴露 15 天和 30 天后,在整个生物体水平和八个器官(鳃,胃,肠,肝胰腺,尾肌,绿腺,甲壳和血淋巴)中分析了汞的生物蓄积.结果分析表明,Hg(II) 和 Mehg 积累有利于 Mehg 的显着差异:对于直接路线,金属浓度之间的比率接近 8;对于营养途径,即使直接加营养污染途径中的 Hg 浓度与

摘要:The subject invention provides methods for the chemical synthesis of racemic arsinothricin (D,L-AST), the novel organoarsenical antibiotic. One is by condensation of the 2-chloroethyl(methyl)arsinic acid with acetamidomalonate, and the second involves reduction of the N-acetyl-protected derivative of hydroxyarsinothricin (AST-OH) and subsequent methylation of the resulting sodium salt of trivalent arsenic intermediate with methyl iodide. The enzyme AST N-acetyltransferase (ArsN1) was utilized to purify L-AST from racemic AST. This expedient chemical synthesis of AST provides a source of this novel antibiotic for future drug development.
