急、慢性铍病病例在国内外陆续可见报道,日趋以慢性中毒为多见。国外报道的慢性中毒病例多属曾接触过铍化合物,经数年至10年的潜伏期而发病,国内则多报道于生产中长时间低浓度接触后发病。但脱离生产接触后的流行病学调查资料至今尚未见报道。为揭示脱离铍作业后工人健康变化情况及慢性铍中毒的发病规律,为防治工作提供科学依据,我们选择了采矿与冶炼为一体的原潮安县冶炼厂停产后脱离铍作业的工人进行追踪观察,现将结果报告如下。1 对象和方法1.1 对象原潮安县冶炼厂是开采绿柱石和提 Acute and chronic beryllium cases have been reported in succession at home and abroad, more and more chronic poisoning is more common. Foreign reports of chronic poisoning mostly belong to beryllium compounds have been exposed to the incubation period of several years to 10 years and the incidence of more domestic reports in the production of low concentrations of long-term exposure after the onset. However, there is still no report about the epidemiological investigation after the outbreak of production. In order to reveal the changes of workers’ health after beryllium operation and the incidence of chronic beryllium poisoning and to provide a scientific basis for prevention and treatment work, we selected the workers from the original mining and smelting operation, which were separated from beryllium after the shutdown of the Chaoan smelter, The results reported below. 1 objects and methods 1.1 Object The original Chaoan smelter is the production of beryl and mention
