Abstract:
This paper presents the phthalate esters (PAEs), nonylphenol (NPs), and microplastics (MPs) in river sediments. Results showed that sediments near residential areas were mainly composed of fine particles, potentially influencing the adsorption of PAEs and NPs in the area. The concentrations of Σ10 PAEs in the sediments ranged between 2448 and 63,457 μg/kg dw, dominated by DEHP and DnOP. Microplastics were detected in all samples, with higher abundances found in sediments near residential areas dominated by polypropylene. Toxicological risk assessment indicated potential risks to sensitive aquatic organisms exposed to the sediments. Correlations between MPs, PAEs, and NPs suggest that MPs may serve as possible sources of PAEs in the sediments. Principal component analysis explained 95.4 % of the pollutant variability in the sediments. Overall, this study emphasizes the significance of monitoring and understanding the presence and interactions of PAEs and MPs in river sediments to assess their potential impacts on aquatic ecosystems.
