炼焦厂焦炉工作地点空气中含有大量致癌碳氢化合物3,4-苯并芘(BaP)。炼焦工人血液和尿中检出这种物质,可用来评价其引起职业性癌的危险性。BaP能溶于苯、环己烷、丙酮等有机溶剂,而不溶干水,但血清、旦白、核酸、嘌呤等助溶物质能提高其在水中的溶解度。在测定炼焦工人体液中BaP含量时应考虑到这些情况在焦炉工人工作时经常长时间逗留的炉顶上方1.5m高度处,采集了空气样品56份。同时,
Coke oven coke oven work place Air contains a large number of carcinogenic hydrocarbons 3,4 - benzopyrene (BaP). Cokes workers in the blood and urine detected this substance, can be used to evaluate the risk of causing occupational cancer. BaP is soluble in benzene, cyclohexane, acetone and other organic solvents, but insoluble in dry water, but serum, white, nucleic acids, purines and other substances can increase its solubility in water. In determining the BaP content of body fluids in coking workers, these conditions should be taken into account when collecting 56 samples of air at a height of 1.5 m above the top of the oven where the coke oven workers often stay for long periods of time while they are working. Simultaneously,
