The exact mechanism of the action of arsenical toxicity is not known clearly, but several hypotheses have been proposed.

到目前为止，人类对砷的毒性作用机制还不是很清楚，但存在多种假设：氧化应激，影响细胞增殖，产生基因毒性如影响DNA甲基化、协同致癌、肿瘤促发等。

Our studies show that children are more vulnerable to arsenical toxicity compared to adults.

The inorganic arsenates ( AsO 4 3-) and the arsenites ( AsO 3 3-) are the main species of arsenic in natural water, while the concentrations of organic arsenic compounds are generally low.

砷在自然水系中主要以无机砷酸盐（AsO43-）和亚砷酸盐（AsO33-）两种形式存在，而砷的有机化合物的含量一般都很低。

A new treatment technology of refractory arsenical gold ores& arseno leaching method

处理难选含砷金矿石的一种新工艺&阿辛诺低压氧化浸出法

METHODS: Twenty_five relapsed APL patients were enrolled ( M 15, F 10, 34 a ± s 12 a), 10 mL of 0.1% arsenous acid solution+ 5% glucose 500 mL was injected iv, drip, daily for 28_56 d.

方法：复发的急性早幼粒细胞白血病25例（男性15例，女性10例；年龄34a±s12a）以亚砷酸10mg／d＋5%葡萄糖注射液500mL静脉滴注，28～56d为一个疗程。

The experiments included both small and extended test. Because the Arsenic in secondary zinc oxide exists mainly in the form of arsenous oxide, which is volatile, the roasting method of adding reductant carbon to secondary zinc oxide is used to remove Arsenic.

本研究实验包括小型实验和扩大实验，由于次氧化锌中砷主要以三氧化二砷形态存在，因此可以通过三氧化二砷易挥发特性，采用在次氧化锌中加入炭还原剂的焙烧方法脱砷。
