Abstract

The present study scrutinizes health risk assessment of BTEX compounds and the variation of BTEX concentration during winter and spring 2022 in indoor air of a painting workstation located in Tehran, Iran. 54 samples were collected according to NIOSH 1501 manual in 3 sub-units. The mean concentrations of BTEX were 3863, 9057, 4097, and 11,471 µg.m−3, respectively. Though the mean concentration of benzene surpassed, toluene, ethylbenzene, and xylene fell within the acceptable range of occupational exposure standard limit (Benzene: 1600 µg.m−3, Toluene: 75,516 µg.m−3, Ethylbenzene: 87,024 µg.m−3, and Xylene: 435,081 µg.m−3). As the results showed, the majority of carcinogenic risks (CR) for benzene and ethylbenzene were estimated to be unacceptable. The highest CR was figured out in the painting area with 8.78E−03 for benzene in the winter season and 2.10E−03 for ethylbenzene in the spring season, respectively. Additionally, the mean CR values of benzene and ethylbenzene were calculated at 2.46E−03 and 8.35E−04, respectively. All non-carcinogenic hazards (HQ) of benzene and xylene exceeded maximum standard level recommended by the US Environmental Protection Agency (EPA) in both seasons, meanwhile, HQs of toluene in winter were greater than 1. The mean HQ values for BTEX were benzene (2.94E + 01) > xylene (2.62E + 01) > toluene (4.07E−01) > ethylbenzene (9.35E−01). Our finding revealed the workers were more likely to be exposed to cancer health risks due to BTEX exposure thus, control measures should be defined to reduce the hazards raised by these chemicals at this workstation.

伊朗德黑兰某工业绘画车间化学品的健康风险评估
本研究对伊朗德黑兰某涂装工作站室内空气中BTEX化合物的健康风险评估及2022年冬、春季BTEX浓度变化进行了详细研究,按NIOSH 1501手册分为3个亚单元采集了54份样本。BTEX的平均浓度分别为3863、9057、4097和11471µg。分别m−3。虽然苯的平均浓度超标,但甲苯、乙苯和二甲苯的浓度均在职业暴露标准限值的可接受范围内(苯:1600µg)。m−3,甲苯:75,516µg。m−3,乙苯:87,024µg。和二甲苯:435,081µg m−3)。结果表明,苯和乙苯的大部分致癌风险(CR)估计是不可接受的。涂装区冬季苯和春季乙苯的CR值最高,分别为8.78E−03和2.10E−03。此外,苯和乙苯的平均CR值分别为2.46E−03和8.35E−04。两个季节苯和二甲苯的非致癌性危害(HQ)均超过美国环保署(EPA)推荐的最大标准值,而甲苯在冬季的HQ均大于1。BTEX的平均HQ值为苯(2.94E + 01) >;二甲苯(2.62E + 01) >;甲苯(4.07E−01)>;乙苯(9.35E−01)。我们的研究结果表明,由于接触BTEX,工人更有可能暴露于癌症健康风险,因此,应制定控制措施,以减少这些化学品在该工作站引起的危害。

期刊介绍: ASE is an international journal that publishes high-quality papers, communications, and discussion that advance aerosol science and engineering. Acceptable article forms include original research papers, review articles, letters, commentaries, news and views, research highlights, editorials, correspondence, and new-direction columns. ASE emphasizes the application of aerosol technology to both environmental and technical issues, and it provides a platform not only for basic research but also for industrial interests. We encourage scientists and researchers to submit papers that will advance our knowledge of aerosols and highlight new approaches for aerosol studies and new technologies for pollution control. ASE promotes cutting-edge studies of aerosol science and state-of-art instrumentation, but it is not limited to academic topics and instead aims to bridge the gap between basic science and industrial applications.  ASE accepts papers covering a broad range of aerosol-related topics, including aerosol physical and chemical properties, composition, formation, transport and deposition, numerical simulation of air pollution incidents, chemical processes in the atmosphere, aerosol control technologies and industrial applications. In addition, ASE welcomes papers involving new and advanced methods and technologies that focus on aerosol pollution, sampling and analysis, including the invention and development of instrumentation, nanoparticle formation, nano technology, indoor and outdoor air quality monitoring, air pollution control, and air pollution remediation and feasibility assessments.
