长时期以来就怀疑砷化合物能够引起人的癌症。最近报道,在8,000名接触三氧化二砷的熔炼工中,呼吸道癌症为一般人的3倍,高度接触并且工作15年以上者竟高达8倍。作者注意到这些工人还接触二氧化硫等其他化学物质,这些因素的影响也不能忽视。 Arsenic compounds have long been suspected of causing cancer in humans. It has recently been reported that among 8,000 smelters exposed to arsenic trioxide, respiratory cancer is three times as common as the average person, and up to eight times more highly exposed and more than 15 years of work. The authors note that these workers also come into contact with other chemicals such as sulfur dioxide, and the impact of these factors can not be ignored.
