Polycyclic aromatic hydrocarbons (PAHs) in atmospheric particulate matter (PM) are high in Saudi cities due to industry and traffic, often exceeding safety limits. This study assesses PM and PM and health risks in Riyadh's desert environment. High-purity chemicals and PAH standards were used. Air samples were collected at King Saud University, extracted, cleaned, and analyzed by GC-MS. QA/QC ensured accuracy, with RSDs of 4.6-7.9%. Seasonal temperature shifts in Riyadh influence PM and PAH levels. Higher summer temperatures raise PM/PAH, posing health risks, especially via inhalation. Winter favors PAH accumulation on particles. Seasonal temperature shifts significantly affect PM, PM, and PAH levels in Riyadh, with summer posing the highest health risks. Inhalation is the main exposure route, especially for PM.
由于工业和交通因素，沙特城市大气颗粒物（PM）中的多环芳烃（PAHs）含量很高，常常超过安全限值。本研究评估了利雅得沙漠环境中的PM及PM与健康风险。使用了高纯度化学品和PAH标准品。在沙特国王大学采集空气样本，进行萃取、净化，并通过气相色谱 - 质谱联用仪（GC - MS）进行分析。质量保证/质量控制确保了准确性，相对标准偏差为4.6 - 7.9%。利雅得的季节性温度变化会影响PM和PAH水平。夏季气温较高会提高PM/PAH水平，带来健康风险，尤其是通过吸入途径。冬季有利于PAH在颗粒物上的积累。季节性温度变化显著影响利雅得的PM、PM和PAH水平，夏季带来的健康风险最高。吸入是主要的暴露途径，尤其是对于PM而言。
