Volatile organic compounds (VOC) are considered a class of pollutants with a significant presence in indoor and outdoor air and serious health effects. The aim of this study was to measure and evaluate the levels of outdoor and indoor VOCs at selected sites on Rhodes Island, Greece, during the cold and warm periods of 2023. Spatial and seasonal variations were evaluated; moreover, cancer and non-cancer inhalation risks were assessed. For this purpose, simultaneous indoor-outdoor air sampling was carried out on the island of Rhodes. VOCs were determined by Thermal Desorption-Gas Chromatography/Mass Spectroscopy (TD-GC/MS). Fifty-six VOCs with frequencies ≥ 50% were further considered. VOC concentrations (∑VOCs) at all sites were found to be higher in the warm period. In the warm and cold sampling periods, the highest concentrations were found at the port of Rhodes City, while total VOC concentrations were dominated by alkanes. The Positive Matrix Factorization (PMF) model was applied to identify the VOC emission sources. Non-cancer and cancer risks for adults were within the safe levels.
挥发性有机化合物（VOC）被认为是一类在室内和室外空气中大量存在且对健康有严重影响的污染物。本研究的目的是在2023年的寒冷和温暖时期，测量和评估希腊罗德岛选定地点的室外和室内VOC水平。评估了空间和季节变化；此外，还评估了癌症和非癌症吸入风险。为此，在罗德岛同时进行了室内外空气采样。通过热解吸-气相色谱/质谱联用仪（TD-GC/MS）测定VOC。进一步考虑了频率≥50%的56种VOC。所有地点的VOC浓度（∑VOCs）在温暖时期更高。在温暖和寒冷采样期，罗德岛市港口的浓度最高，而总VOC浓度以烷烃为主。应用正定矩阵因子分解（PMF）模型识别VOC排放源。成人的非癌症和癌症风险处于安全水平。
