Abstract

Each time a car's brakes are used, asbestos is dispersed in the air. Breathing the air in enclosed parking lots can expose people working in these places to asbestos. This study aimed to evaluate the airborne asbestos dispersion in enclosed parking lots. In this study, 35 air samples were collected from six enclosed parking lots in Tabriz City. The samples were analyzed quantitatively by phase contrast microscopy (PCM) and qualitatively by a scanning electron microscope (SEM) equipped with an energy-dispersive X-ray analyzer. The mean of fiber concentrations was found 0.155 ± 0.069 PCM f/cc. The SEM data demonstrated that the fibers consisted of synthetic fibers (69.57%) and asbestos (30.43%). Fiber concentrations in many enclosed parking lots in the city were higher than the threshold limit value-time weighted average of the American Conference of Governmental Industrial Hygienists and Occupational Exposure Limits of Iran. However, further investigations are needed to clarify asbestos exposure in such places.

评价伊朗封闭停车场空气中石棉的扩散。

每次使用汽车刹车时，石棉就会分散到空气中。在封闭的停车场呼吸空气会使在这些地方工作的人接触到石棉。本研究旨在评估封闭停车场空气中石棉的扩散。在本研究中，从大不里士市的六个封闭停车场收集了35个空气样本。采用相衬显微镜(PCM)对样品进行定量分析，并采用配备能量色散x射线分析仪的扫描电子显微镜(SEM)对样品进行定性分析。纤维浓度平均值为0.155±0.069 PCM f/cc。SEM数据表明，纤维主要由合成纤维(69.57%)和石棉(30.43%)组成。该市许多封闭式停车场纤维浓度高于美国政府工业卫生学家和伊朗职业暴露限值会议的阈值-时间加权平均值。然而，需要进一步的调查来澄清这些地方的石棉暴露情况。

期刊介绍： Archives of Environmental & Occupational Health , originally founded in 1919 as the Journal of Industrial Hygiene, and perhaps most well-known as the Archives of Environmental Health, reports, integrates, and consolidates the latest research, both nationally and internationally, from fields germane to environmental health, including epidemiology, toxicology, exposure assessment, modeling and biostatistics, risk science and biochemistry. Publishing new research based on the most rigorous methods and discussion to put this work in perspective for public health, public policy, and sustainability, the Archives addresses such topics of current concern as health significance of chemical exposure, toxic waste, new and old energy technologies, industrial processes, and the environmental causation of disease such as neurotoxicity, birth defects, cancer, and chronic degenerative diseases. For more than 90 years, this noted journal has provided objective documentation of the effects of environmental agents on human and, in some cases, animal populations and information of practical importance on which decisions are based.
