肥皂生产工人接触硫酸和镍尘,二者均疑有致癌作用。本文对意大利一家肥皂生产厂工人中全死因和肿瘤死亡率以及呼吸道发病率作了研究,以探讨肥皂生产过程中硫酸蒸气对人的致癌危险。 这家工厂位于意大利中部,具有50年肥皂生产历史,车间空气中硫酸蒸气浓度为0.64～1.12mg/m~3,矿物油1.2mg/m~3,尚有其它污染物,如镍、肥皂粉、甘油和脂肪酸。研究对象为从1964年1月1日起至1972年进厂且至少工作一年的工人,共计361名,观察至
Soap production workers exposed to sulfuric acid and nickel dust, both suspected carcinogenic. In this paper, a study was conducted on all-cause and oncological mortality and respiratory morbidity among workers in a soap factory in Italy to investigate the carcinogenic risk of sulfuric acid vapor to humans during soap production. The plant is located in central Italy, with 50 years of soap production history. The concentration of sulfuric acid vapor in the air is 0.64 ~ 1.12mg / m ~ 3 and the mineral oil is 1.2mg / m ~ 3. Other pollutants such as nickel, soap powder , Glycerin and fatty acids. The object of study was a total of 361 workers who entered the factory from January 1, 1964 and took at least one year’s work.
