The potential leaching of organic micropollutants from swimming accessories was studied in the laboratory experiment. Seventeen different swimming accessories have been placed in various water matrices under different conditions in order to reproduce the actual environmental conditions of swimming pool water. The presence of micropollutants in water samples, after the exposure of swimming accessories, was assessed using indirect indicators (Total Organic Carbon and Phenol Index) and directly using a gas chromatograph coupled with a mass spectrometer with electron ionization. A wide range of organic compounds emitted from swimming accessories have been identified. The most common in tested samples was isophorone. The frequency of its occurrence in 50 swimming pools located in Poland was equal to 89% in concentrations ranged from 0.75 to 1.01 µg L-1 (below the concentration of 40 µg L-1, which is estimated to increase the cancer risk). Content of combined chlorine (1.52-3.16 mgCl2 L-1) in chlorinated matrices indicated a high potential for disinfection by products (DBPs) formation from organic matter emitted into pool water from swimming accessories. Ten of seventeen tested samples showed the toxic effect, measured as the bioluminescence inhibition of bacteria Aliivibrio fischeri.

游泳配件向游泳池水中排放有机微污染物的潜力。

在实验室实验中研究了从游泳配件中浸出有机微量污染物的可能性。为了重现游泳池水的实际环境条件，已经在不同条件下将17种不同的游泳配件放置在各种水基中。使用间接指示剂（总有机碳和苯酚指数）并直接使用气相色谱仪结合带电子电离的质谱仪，评估了游泳配件暴露后水样品中微量污染物的存在。已经确定了游泳配件散发出的多种有机化合物。测试样品中最常见的是异佛尔酮。它的发生频率在波兰的50个游泳池中，浓度从0.75到1等于89％。01 µg L-1（低于40 µg L-1的浓度，估计会增加患癌的风险）。氯化基质中合并氯的含量（1.52-3.16 mgCl2 L-1）表明，从游泳配件排放到泳池水中的有机物形成副产物（DBP）的可能性很高。测试的十七个样品中有十个显示出毒性作用，用细菌Aliivibrio fischeri的生物发光抑制来衡量。
