Individual exposures were qualitatively and quantitatively characterized for "Xylols" manufacturing workers. To this end, air sampling was performed from the breathing zones of workers occupied at varying jobs, covering a representative group of 29 subjects; for comparison, 17 stationary samples were taken from work-places at the same facility. A gas chromatographic procedure specially developed for the purpose was used for identification and quantitative analysis of the substances recovered. Fatty and aromatic hydrocarbons were found to be the principal pollutants of the occupational atmosphere. The leading pollutant proved to be benzene, by virtue of its high toxicity and relatively high levels (around and above its MAC).
对“二甲苯”制造工人的个体暴露进行了定性和定量表征。为此，从从事不同工作的工人呼吸区进行了空气采样，涵盖了29名受试者的代表性群体；作为比较，从同一工厂的工作场所采集了17个固定样本。专门为此目的开发的气相色谱程序用于对回收的物质进行鉴定和定量分析。脂肪烃和芳烃被发现是职业环境中的主要污染物。由于其高毒性和相对较高的水平（在其职业接触限值左右及以上），主要污染物被证明是苯。
