Key Points

Co-occurrence of metals and PFAS was observed in mangrove sediments, indicating environmental contamination.
Sediment samples reveal that older mangrove forests show different levels of PFAS compared to younger ones.
Assessment using sediment analysis across various salinity levels highlights the distinct variations in contamination.
Findings suggest that both forest age and salinity gradient significantly affect the distribution of metals and PFAS.
