吸收、分配和排泄
在焦化设施工业中,研究了邻甲酚、间甲酚、对甲酚、2,4-二甲酚、2,5-二甲酚、3,4-二甲酚和3,5-二甲酚的暴露水平与尿中酚排泄之间的关系。研究对象包括从事焦油蒸馏过程的76名暴露工人和34名对照组。... 尿液代谢物水平已针对比重和肌酐进行了校正。焦油蒸馏工人的呼吸区域的时间加权平均暴露浓度是... 对于二甲酚为0.02至0.04 mg/立方米。... 经比重校正后,暴露工人的尿液中二甲酚水平范围为0.12至0.97 mg/l。在对照组尿样中,经比重校正的二甲酚浓度范围为25 x 10(-3)至43 x 10(-3) mg/l。观察到环境水平与尿液中酚、邻甲酚和二甲酚浓度之间存在显著相关性,相关系数范围为0.45至0.82。作者结论,尿液二甲酚的生物监测可能用作衡量焦化设施工人二甲酚暴露的一种方法。
Associations between o-cresol, p-cresol, m-cresol, 2,4-xylenol, 2,5-xylenol, 3,4-xylenol, and 3,5-xylenol exposure levels and urinary phenol excretion were examined in the coke facility industry. The subjects consisted of 76 exposed workers employed in the tar distillation process and 34 controls. ... Urinary metabolite levels were corrected for specific gravity and creatinine. The time weighted average exposure concentrations in the breathing zones of the tar distillation workers were ... 0.02 to 0.04 mg/cu m for xylenols. ... The urinary xylenol levels of exposed workers ranged from 0.12 to 0.97 mg/l with specific gravity correction. In control urine samples, the specific gravity corrected xylenol concentrations ranged from 25 x 10(-3) to 43 x 10(-3) mg/l. Significant correlations were observed between the ambient levels and urinary concentrations of phenol, o-cresol, and the xylenols, with coefficients ranging from 0.45 to 0.82. The author concludes that the biological monitoring of urinary xylenols may be used as a means of measuring xylenol exposure in coke facility workers.
