摘要：There is a lack of information on polycyclic aromatic hydrocarbons (PAHs) as environmental pollutants in Saudi Arabia.The current study focuses on the risk assessment of polycyclic aromatic hydrocarbons (PAHs),in the Holy city of Makkah, Saudi Arabia, during Hajj season 1431H.Atmospheric particulate matter was collected using High Volume samplers.Samples of 24h were collected at three sampling sites, Al-Shebakah, Al-Aziziah and Mina.PAH compounds were quantified by using GC.The total PAH concentrations (ng/m3) ranged from 103.5 - 195.2 with mean values of 164.67, 137.81 and 132.40 for TSP, PM10, PM2.5, respectively.The higher percentages of the total carcinogenic compounds were recorded at Al-Shebakah, with a maximum value of 63.5 % in PM10.The carcinogenic PAHs, dibenzo[a]pyrene was found at low concentrations.
