Rivers provide vital ecosystem services for populations. However, these ecosystems face several anthropogenic threats, including macrolitter pollution, and their impacts remain inadequately understood. This study aimed to evaluate the ecological status of Leça river (northern Portugal) according elements defined by Water Framework Directive (WFD) quantify marginal as a new tool water quality assessment. Physical, chemical, biological (photosynthetic pigments; benthic macroinvertebrates) were quantified status, seven sites (P1 P7) along throughout four seasons (autumn/23, winter/24, spring/24, summer/24). Macrolitter was collected on riverbank each site categorized standard protocols. Based physical chemical elements, achieved Good in P1, Moderate P4 P7 (mainly due nutrient enrichment) with P2 P3 varying between Moderate. The macroinvertebrate community varied between: P1; Poor P3; P5; Bad P6 P7. From 1717 items (belonging 86 categories), artificial polymer/plastic most frequent (56.67 %). More abundance diversity P7, coinciding increasing anthropic presence. A multivariate analysis revealed that originating from recreational activities associated fewer alterations community, while deposition domestic, industrial, commercial residues more degraded conditions. results suggest evaluation can be used indicate threaten aquatic ecosystems.

Abstract Plastic products have resulted in enormous pollution many ecosystem types and regions worldwide. The problem is particularly prominent within aquatic environments, where multiple anthropogenic sources (i.e., agriculture, urbanisation, industries, illegal dumping) are common, exacerbated by interconnectedness between terrestrial environments management challenges. Regional disparities also common macroplastic research, with a scarcity of knowledge African freshwaters. Here, considering seven riparian sites across four seasons, we determined the abundance distribution litter along South Crocodile River system its associated tributaries. Macroplastics were sorted classified into various polymer groups, functional origins, physical forms for each site season. We hypothesised that abundances would be substantial, differences among related to human activities river shores, during summer months when recreational was high. observed significant variation high autumn (338), while lower total numbers macroplastics unexpectedly collected spring (243–263). High proportional plastic bags film all seasons observed, as well polypropylene polymers. Our study serves baseline understanding seasonal variations their driving factors subtropical systems, which may help inform policies. further contributes resolving gaps underrepresented regions, providing novel insights sources, accumulation, impacts linked unique socio-environmental contexts. Thus, it bridges critical data gaps, informing targeted interventions global comparative analyses waste management.
