| Abstract: | "Chemicals containing Volatile Organic Compounds (VOCs) are commonly used in the machine carpet production. 1,3-butadiene and styrene are main components of the carpenter's glue used in carpet factories. Exposition to these chemicals can lead to a number of adverse health effects. This is the first study of the human health risk assessment due to inhalational exposure to 1,3-butadiene (BD) and styrene (ST) performed among workers in the carpet factories in Kashan city, Iran. The importance of the study was related with the fact of high popularity of carpet production in the South Asia countries. Inhalation exposure to BD and ST were measured based on the National Institute for Occupational Safety and Health (NIOSH) 1024 and 1501 methods, respectively. The cancerogenic risk (CR) and non-cancerogenic risk described as Hazard Quotient (HQ) values were calculated based on the United States Environmental Protection Agency (USEPA) method. The sensitivity and uncertainty analysis were performed by the Monte Carlo simulation (MCS) technique. The average concentration measured of BD and ST during work shifts of employees were 0.039 mg m(-3) (0.017 ppm) and 12.108 mg m(-3) (2.84 ppm), respectively. The mean +/- SD value of estimated cancerogenic risk in inhalation exposure to BD and ST were equal to 5.13 x 10(-3) +/- 3.85 x 10(-4) and 1.44 x 10(-3) +/- 2.36 x 10(-4), respectively exceeding the acceptable risk level of 10(-6) defined by USEPA. The average non-carcinogenic risk (HQ) values of BD and ST were equal to 8.50 x 10(0) and 5.13 x 10(0), respectively exceeding the acceptable risk level of 1. As the results of our studies exceeded both cancerogenic and non-carcinogenic risk values it indicates that adverse health effects due to inhalational exposure to BD and ST for workers in the machine carpet industry are very likely. To avoid negative health effects protective measures for employees in the factories should be introduced immediately and furher detailed research are recommended" |
