有机砷

高效光氧化反应管能够在几秒的时间内将有机砷（MMA和DMA）氧化成As（V）。

Using high efficiency photooxidation reactor , organic arsenic species ( MMA and DMA ) could be oxidized to As ( V ) in several seconds .

湖水表面微层和表层中占优势的砷形态均为AS（V），在表面微层和表层湖水中存在的有机砷形态主要为DMA；

As ( V ) is a dominant arsenic species present in both surface microlayer and surface layer of lake water , and DMA is a major organic arsenic species present in both layers .

同样环境条件下，DMA的脱甲基化速率明显快于MMA；DMA、MMA两种有机砷的最快转化的土壤水分条件分别为100%最大田间持水量和70%最大田间持水量。

Under the same condition , the demethylation speed of DMA is apparently faster than MMA ; The optimal soil moisture for the transformation of DMA and MMA are 100 % , 70 % of the maxmun field capacity . 3 .

洛克沙砷作为一种人工合成的有机砷化物，被大量用作动物促生长添加剂添加到畜禽饲料中。

Roxarsone is a kind of man-made organic compound contains Arsenic element , which has been used for years as an additive in animal 's diet to accelerate animal growth .

虽然有机砷的毒性最小，然而在农药施用区似乎土壤中残存有机制约占总砷量的1/2或1/3。

Although the toxicity of organic As is less than that of inorganic As , half or 1 / 3 of total As in the soils applied with pesticide are organic As .

为能够比较直观地反映有机砷制剂在畜禽体内的代谢情况，以正确控制该兽药在猪饲养过程中的应用，提供了新的思路。

To be able to more directly reflect the preparation of organic arsenic metabolism in the animal body to properly control the process of veterinary drugs in pig breeding applications , provides a new way of thinking . 1 .
