CCA浸渍的木材含有铜、铬和砷（CCA），在使用这种木材的工作中，可能会出现职业接触木尘以及CCA化合物的情况。市售浸渍木材产生的粉尘被发现含有六价铬，这被认为是一种致癌物质。因此，除了测定CCA化合物的总量外，还必须测定六价铬的具体含量。对六个细木工车间的工作环境进行了选择性的控制。木屑平均暴露量低于1 mg m-3。各类细木工机械周围空气中砷的平均浓度在0.54 ~ 3.1微克-3之间。没有在任何样品中检测到六价铬，也没有在工人的尿液中发现砷浓度增加。在对细木工车间的职业环境进行适当评估时，必须考虑到车间空气中砷的存在。
CCA-impregnated timber contains copper, chromium and arsenic (CCA), and occupational exposure to wood dust as well as the CCA compounds may occur in work with such timber. Dust from commercially available impregnated wood has been found to contain hexavalent chromium, which is regarded as a carcinogen. Apart from determinations of the total amounts of the CCA compounds, specific determination of hexavalent chromium is therefore essential. Selective methods have been applied for control of the work environment in six joinery shops. The mean exposure to wood dust was found to be below 1 mg m-3. The mean airborne concentration of arsenic around various types of joinery machines was in the range from 0.54 to 3.1 micrograms m-3. No hexavalent chromium was detected in any samples and no increased concentrations of arsenic were found in urine from the workers. The presence of arsenic in the work-room air must be considered for appropriate assessment of the occupational environment in joinery shops.
