通过对191名砷化物、铅、苯、聚氯乙烯作业工人外周血淋巴细胞微核率的测定,探讨其在职业病诊断上的意义。1对象和方法1.1对象结合职业健康检查资料,选择单一接触砷化物、铅、苯、聚氯乙烯的工人共计191人为调查对象,采用原子荧光光谱法、原子吸收光谱法、溶剂解吸气相色谱法测定作业场所砷化物、铅、苯、聚氯乙烯浓度。另取同一地区不接触任何工业毒物的职业人群53人为对照组,两组性别构成、年龄、工
Through the determination of micronucleus rate of 191 peripheral blood lymphocytes from 191 arsenic, lead, benzene and polyvinyl chloride workers, its significance in the diagnosis of occupational diseases was explored. 1 Subjects and methods 1.1 Subjects Occupational health examination data, select a single exposure to arsenic, lead, benzene, polyvinyl chloride workers a total of 191 people surveyed by atomic fluorescence spectrometry, atomic absorption spectrometry, solvent desorption gas chromatography Workplace arsenic, lead, benzene, polyvinyl chloride concentration. In addition, 53 occupational groups without exposure to any industrial toxicants in the same area were taken as the control group. The two groups were gender, age,
