以某焦化厂焦炉车间153名生产工人和无职业性多环芳烃接触者50人为研究对象。记录其离开工作岗位的时间,收集晨尿。用高效液相色谱法测定尿中1-羟基芘水平。采用方差分析和协方差分析的统计学方法研究不同焦炉位置作业及脱离职业暴露后不同时间对尿1-羟基芘水平的影响。焦炉工尿1-羟基芘水平呈现炉顶>炉侧>炉底>对照趋势;脱离职业暴露后,焦炉工尿1-羟基芘水平呈8 h以内组>8~16 h组>16 h以上组趋势。说明焦炉的作业位置以及脱离职业暴露后的时间均可影响焦炉工尿1-羟基芘水平。
A coke oven workshop 153 workers and non-occupational PAHs were 50 people for the study. Record the time to leave the job, morning urine collection. Determination of 1-Hydroxypyrene in Urine by High Performance Liquid Chromatography. The variance analysis and covariance analysis were used to study the effects of different coke ovens on home-use position and urinary 1-hydroxypyrene levels at different times after occupational exposure. Urine 1-hydroxypyrene levels in coke oven workers showed a trend of "top of furnace> side of furnace> bottom of furnace> control; after exposure to occupational exposure, urinary 1-hydroxypyrene levels in coke oven workers were within 8 hours and within 8 hours to 16 hours The trend of the above group. Coke oven shows that the operating position and time from occupational exposure can affect the coke oven urine 1-hydroxy-pyrene level.
