dc.description.abstractThe presence of mycotoxins in indoor environments is an emerging public health concern, particularly in specific indoor and occupational environments. Cytotoxicity assessment provides relevant information on the biological effects of complex environmental contaminant mixtures. Grocery stores and fitness centers represent distinct indoor environments with different exposure dynamics and contamination sources, requiring integrated evaluation approaches. This study aimed to compare mycotoxin contamination and cytotoxic potential, assessed using the HepG2 and A549 cell lines, of environmental matrices from two projects conducted in Portugal: grocery stores in 2021 and fitness centers in 2024. In grocery stores, only EDC samples were analyzed, whereas in fitness centers, a wider sampling campaign, using more sampling methods, was employed (EDCs, filters, and cleaning mops). Regarding mycotoxins, fumonisins B1, B2, and B3 were identified in EDC samples from grocery stores. In fitness centers, fumonisin B2 was detected in all matrices analyzed. Cytotoxicity assessment revealed distinct responses between settings and cell lines. In grocery stores, cytotoxic effects were limited, with only one EDC sample showing a positive response in the HepG2 cell line and one EDC sample in the A549 cell line. In fitness centers, the HepG2 cell line showed positive cytotoxic responses in filter and EDC samples, while mop samples did not induce cytotoxicity. The A549 cell line exhibited positive responses across all analyzed matrices. Overall, mycotoxins were detected in greater variety in grocery stores, while fitness centers showed higher cytotoxic potential, highlighting the need for integrated monitoring of contamination and biological effects in indoor environments.eng
