  In Karaj, the large volume of wastes was produced due to the high level of construction activities such as demolition of old buildings and the construction of new buildings. In this regard, it is necessary to have management system with environmental protection perspective for the construction and demolition wastes (CDW). Therefore, the main purpose of this research was study of the amount and composition of CDW in Karaj municipality zones (10 zones) in 2017 with the financial support of Karaj municipality. In the first step, a little amount of CDW was investigated by Karaj waste management organization's statistics. The results showed that the Karaj construction sector produces 5973 tons (2186410 tons/year) of CDW every day, which is around 3% of the total amount of the country generated CDW. Also, the share of per capita CDW production is 1220 kg/year for each person per year and the maximum CDW generation rate was in the November and December and the minimum one was in March and April. In the second step, the composition of CDW was determined using field observations of the disposal sites and landfills. The average composition of CDW showed that up to 80% of the wastes are composed of the soil operation (soil, sand, stone and …) asphalt and concrete parts, building materials (such as brick, block, plaster, pottery, mosaic, etc.) Manuscript profile

  In this paper, carcinogenic and non-carcinogenic risk assessment is investigated by inhalation volatile organic components in the ambient air of Khorramabad. These compounds include benzene, ethylbenzene , toluene , xylenes (BTEX) and normal Hexane. To assess the risk ,first two different scenarios were defined based on the exposure of people to the organic compounds in question and the duration of respiration. Then, the average amount of intake CDI or respiration of mentioned pollutants during life was extracted based on dual scenarios in 11 areas of Khorramabad city. The carcinogenic risk for benzene and ethylbenzene compounds as well as the non- carcinogenic risk for all pollutants discussed in both scenarios were calculated and discussed. It should be noted that due to the high amount of calculations and ease and accuracy in results, programming was done in excel software environment and the initial and final results were calculated directly from this method and the necessary diagrams were drawn. According to the calculation , the annual risk and the total risk of carcinogenicity of inhaling the pollutants in question in the air of Khorramabad for the first scenario are equal to 1.51 E -06 and 5.65 E-01 people per year , respectively. Also, the annual risk and the total risk for the second scenario are 6.19E-07 and 2.31 E-01 per year ,respectively. In addition , the non-carcinogenic risk index for inhalation of the these compounds in the ambient air of Khorramabad is 3.898 and 0.594 for the first and second scenarios respectively.
