Résumé fourni par la source

Chemical composition and oxidative potential measured on monthly samples of PM2.5 and PM10 collected at 22 sites of different typology in the area of Lecce between December 2021 and December 2022. The sites included the Environmental-Climate Observatory (ECO) for intercomparison purposes and quality assurance. Oxidative potential was determined by using the DTT assay. Chemical composition was determined by different techniques: ED-XRF, carbon analyser, ion chromatography, and TOC-TN.
