The accumulative quantity of arsenic in earthworms were relative to the content of arsenic in soil.

说明蚯蚓是土壤中洛克沙胂污染的较好的指示生物。

A new method for the direct synthesis of α-acyl methylenetriphenyl-arsoranes from readily available arsonium salts was afforded.

提供了一个由α-位具有强吸电子取代基的鉮盐一步合成α-酰基胂叶立德的新方法。

Arsine is a toxic, colorless gas with a garlic-like odor at room temperature and atmospheric pressure.

胂是一种无色有毒气体，在室温和大气压力下会发出类似大蒜的气味。

Arsine is a colorless, poisonous gas that requires careful handling.

胂是一种无色的有毒的气体需要小心地对待。

Moreover, the polymeric arsine palladium(0) complex is an efficient catalyst for the carbonyl allylation of aldehydes and the coupling reaction of aryl halides with terminal alkynes or Grignard reagent.

该聚合物负载的胂钯(0)配合物还是醛的羰基烯丙基化及芳基卤化物与端炔、Grignard试剂的交叉偶联反应的有效催化剂。

Earthworms might be a good bioindicator for the contamination of roxarsone to soil. No significant influence of roxarsone contamination upon the biomass and the reproductive ability of earthworms was found, which indicated that earthworms could tolerate heavy contamination of roxarsone. 2. Effects on the important enzymatic system of earthworms The activities of PROD, BROD and MROD in P450 family were inhibited.

对蚯蚓体内重要酶系统的影响洛克沙胂对P450酶系中的PROD（7-戊氧基异吩噁唑酮-O-脱乙基酶）、BROD（7-苄氧基异吩噁唑酮-O-脱乙基酶）和MROD（7-甲氧基异吩噁唑酮-O-脱乙基酶）的活性都有抑制作用，对MROD的抑制作用最明显；在抗氧化酶系统中，对过氧化氢酶在整个试验进程中都有激活作用，而对其他抗氧化酶有时起激活作用，有时起抑制作用，规律性不明显。

The reaction of arsenazo with lanthanum and gadolinium in aqueous solu- tion Was studied by the spectrophotometric method.

在水溶液中用分光光度法研究了偶氮胂Ⅲ与稀土元素镧、钆的反应。

Meanwhile, the standard experiment on addition of small molecular organic arsenics revealed that the small molecular organic arsenics such as cacodylic acid, disodium methylarsonate were detected to be inorganic arsenic by the two detection methods with high recovery efficiency.

同时，试验中用小分子有机砷进行加标试验，结果表明：二甲基胂酸、甲基胂酸二钠等小分子有机砷对两种测定方法的影响很大，会把小分子有机砷作为无机砷检测出来，且检出回收率很高。

Therefore the acute and chronic tests of roxarsone to earthworms were performed in this study in order to know the toxicity and mechanism of toxicosis of roxarsone on environmental organisms.

鉴于此，本课题进行了洛克沙胂对蚯蚓的急性毒性及长期低浓度暴露下对蚯蚓的慢性毒性和毒理的研究，以期为研究和评价洛克沙胂对土壤环境的污染提供依据。
