Abstract：
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 (∑56VOCs) 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.
摘要：
挥发性有机化合物（VOC）被认为是一类污染物，在室内和室外空气中存在大量污染物，并对健康造成严重影响。这项研究的目的是测量和评估罗得岛选定地点的室外和室内挥发性有机化合物的水平，希腊,在2023年的寒冷和温暖时期。评估了空间和季节变化；此外，评估了癌症和非癌症吸入风险.为此,同时在罗得岛进行室内室外空气采样。通过热脱附-气相色谱/质谱(TD-GC/MS)测定VOC。进一步考虑了56种频率≥50%的VOC。在温暖时期，所有地点的VOC浓度（∑56VOC）均较高。在温暖和寒冷的采样期间，最高浓度是在罗得岛港,而总VOC浓度以烷烃为主。应用正矩阵分解（PMF）模型来识别VOC排放源。成人的非癌症和癌症风险在安全水平内。
