流行病学研究表明,镍冶炼厂工人发生肺癌、鼻窦癌和喉癌的风险较高。在啮齿动物研究表明某些含镍成份有致癌作用。本文试图研究镍冶炼过程是否可能对工人构成遗传危害。镍冶炼包括粉碎、焙烧、熔炼和电解工序,在前三个工序中,工人主要吸入重水溶性(heavy water-soluble)NiO和Ni_3/S_2的干燥灰尘,在电解工序中主要吸入水溶性NiCl_2和NiSO_4烟雾。受检者分为三
Epidemiological studies have shown that nickel smelters have a higher risk of developing lung cancer, sinus cancer, and laryngeal cancer. Research in rodents has shown that certain nickel-containing ingredients are carcinogenic. This article attempts to investigate whether the nickel smelting process may pose a genetic hazard to workers. Nickel smelting includes pulverization, roasting, smelting and electrolysis processes. In the first three processes, workers mainly inhaled dry water with heavy water-soluble NiO and Ni_3 / S_2. In the electrolysis process, mainly water-soluble NiCl2 and NiSO_4 smoke. Subjects were divided into three
