鉴于近年来有机砷作为一种除草剂在林业上推广使用,而这类化合物的安全性和从人体排泄的阈值均未很好确定,作者观察了接触二甲砷酸的5名健康青年林业男工为期两个月的尿砷、血砷和临床表现。5名工人在接触二甲砷酸前无皮肤,肠道、神经精神、血液等方面的疾病。每周接触二甲砷酸的时间平均为23.7小时,每周每人接触量(干重)为817克。工作时均穿戴防护衣具。两月期间,每周一次化验血砷和24小时尿砷。在工作结束后,再次进行了体检、化验和询问症状,没有发现异常。另选5名未接触二甲砷酸的工人作对照。
In view of the promotion of the use of organic arsenic as a herbicide in forestry in recent years, and the safety of such compounds and the threshold for excretion from human body, the five healthy young men who were exposed to coca-arsenate were observed. Two months of urine arsenic, blood arsenic and clinical manifestations. Five workers had no skin, gut, neuropsychiatric, or blood-related diseases before they were exposed to coca-arsenic. Weekly exposure to cro-arsenic acid was 23.7 hours on average and 817 grams per person per week exposure (dry weight). Wear protective clothing when working. During the two months, blood arsenic and 24-hour urine arsenic were tested weekly. At the end of the work, the physical examinations, laboratory tests and inquiries were again conducted and no abnormalities were found. Five other workers without exposure to cocaine were selected as controls.
