Environmental Impact Of 2A 2B Carcinogenic Polycyclic Aromatic Hydrocarbons (PAHs) in Industrial Soil: Status, Profile, Concentration and Assessment to Humans Health Risk

<title>Abstract</title> Due to the health and environmental impact resulting from the percentage of soil pollutants due to polycyclic aromatic hydrocarbons PAHs emitted from different sources, especially in industrial areas, and the spread of pollutants in neighboring neighborhoods, and the extent of their impact on children and adult, especially children as a result of their behavior known as soil ingestion or through exposure to soil directly from Through skin contact or inhalation of contaminated soil dust<bold>.</bold> The objective of the research to know the percentage of pollution by polycyclic aromatic hydrocarbons (2A and 2B) as carcinogens human effect for industrial areas, specifically the automobile industry in the city of Riyadh, Naseem Industrial (NAI), Old Industrial (OLI), Gulf Industrial (GUI), Al-Shifa Industrial (SHI) and Umm Al-Hamam Industrial (UMH). Surface soil from the industrial areas within the range of 0-10 cm as well as from the neighborhoods adjacent to the industrial areas. The percentage of pollution by PHAs according to Agency for Research on Cancer classified BaP, DBA, and BaA as probable human carcinogens (2A) while BbF, BkF, and IND as possible human carcinogens (2B). IARC has evaluated Nap and CRY reclassified it possible human carcinogens. the extraction technique quick, easy, cheap, effective, rugged, and safe (QuEChERS) for the ∑8 PAHs and GC-MS used to estimate the results in the extracted samples. The result for potential risks for both children and adults only were found to be exposed to BaP and DBA in street dust in different land areas in Riyadh. Mean ILCR_ing and ILCR_der values and cancer risk based on mean total concentrations of PAHBaP_equi for children and adults exposed to PAHs in street dust in different regions of Riyadh were found between 10^-9 and 10^-4, indicating a potential risk.
