摘要： The presence of priority and emerging contaminants in aquatic environments is a worldwide concern. This study utilized the diffusive gradients in thin-films (DGT) technique for in situ monitoring of polycyclic aromatic hydrocarbons (PAHs) and synthetic musks (SMs) in coastal waters over a year. DGT provided time-integrated and reliable pollutant measurements, outperforming grab sampling in terms of repeatability and stability. Seasonal and spatial variations in PAH and SM concentrations were observed, influenced by proximity to vehicle and maritime transport and tourist areas. Source apportionment using diagnostic ratios, positive matrix factorization, and principal component analysis indicated mixed pollutant origins. High ecological risks for certain PAHs emerged in the summer, highlighting significant seasonal threats. These findings provide critical insights for the long-term monitoring and management of PAHs and SMs, offering valuable regional data to support pollution mitigation efforts in the coastal water.
