This study analyzes the effects of washing conditions on polycyclic aromatic hydrocarbon (PAH) content in firefighter protective clothing. The analysis involved specially prepared textile packages made of materials used in such clothing: an outer shell, a moisture barrier membrane, and a thermal insulation lining. Package samples were subjected to simulated exposure to a selected group of PAH compounds. Ultra-high-performance liquid chromatography with fluorescence detection (UHPLC/FL) was applied to determine PAH content. The study showed that washing conditions (water temperature and the number of rinses) influenced the effectiveness of removal of chemical contaminants. The most favorable results were obtained for the washing process conducted at 60 °C with three rinse cycles, which resulted in the lowest concentration of total PAHs in the two examined types of textile packages (0.40 µg·g and 0.60 µg·g in the outer shell, 3.9 µg·g and 6.2 µg·g in the membrane, and 0.40 µg·g and 0.41 µg·g in the thermal lining of packages A and B, respectively). The higher washing temperature (60 °C) had a more favorable effect on average washing effectiveness as compared with the lower temperature (40 °C) in both the two- and three-rinse variants. The average washing effectiveness also varied according to the type of material and amounted to 70% and 54% for textile package types A and B, respectively.
本研究分析了洗涤条件对消防员防护服中多环芳烃(PAH)含量的影响。该分析涉及用此类服装所使用的材料制成的特制纺织包:外壳、防潮膜和隔热衬里。对包样品进行了选定的一组PAH化合物的模拟暴露。采用带荧光检测的超高效液相色谱法(UHPLC/FL)测定PAH含量。研究表明,洗涤条件(水温及漂洗次数)影响化学污染物的去除效果。在60℃下进行三次漂洗循环的洗涤过程取得了最有利的结果,这使得在两种测试的纺织包类型中总PAHs的浓度最低(包A和包B的外壳中分别为0.40μg·g和0.60μg·g,膜中为3.9μg·g和6.2μg·g,隔热衬里中为0.40μg·g和0.41μg·g)。与较低温度(40℃)相比,较高的洗涤温度(60℃)在两次漂洗和三次漂洗变体中对平均洗涤效果都有更有利的影响。平均洗涤效果也因材料类型而异,纺织包类型A和B的平均洗涤效果分别为70%和54%。
