观察了甲苯、混合溶剂和汞蒸气等化学物对工人神经行为的影响。研究人群第1组为电子工厂接触甲苯女工30人,平均年龄25.6岁,平均接触甲苯5.7年,接触甲苯的平均浓度为341mg/m~3。对照组为同一工厂不接触甲苯的女工30人,平均年龄25.1岁;第2组为从事印刷、塑料及包装等工作接触混合溶剂的男工24人,平均年龄24.7岁,平均接触溶剂2.3年,所接触的混合溶剂相当于甲苯浓度
The effects of chemicals such as toluene, mixed solvents and mercury vapor on the neurobehaviors of workers were observed. The first group of research population for the electronics factory contact with 30 women workers, with an average age of 25.6 years old, with an average exposure to toluene 5.7 years, the average contact concentration of toluene 341mg / m3. The control group consisted of 30 female workers who did not touch toluene in the same factory, with an average age of 25.1 years. The second group consisted of 24 male workers in contact with mixed solvents such as printing, plastic and packaging, with an average age of 24.7 years. The average exposure time was 2.3 years. The mixed solvent contacted corresponds to the toluene concentration
