“…Several studies have also reported blue as the most common colour, such as Goswami et al [51], the authors of which determined that blue MPs represent 50% of all the MPs found in zooplankton. Trindade et al (2023) points to blue pigment stability as a possible reason for the high numbers and persistence of blue plastics in the environment [10]. Many blue pigments, such as indigo blue (widely used in the textile industry, especially in denim manufacturing), have a high colour stability and a high resistance to heat and light [10,52].…”

Many blue pigments, such as indigo blue (widely used in the textile industry, especially in denim manufacturing), have a high colour stability and a high resistance to heat and light [10,52]. In particular, blue fibres from denim manufacturing have been identified as a major indicator of anthropogenic pollution [53].…”

“…MPs are transported to different regions and ecosystems, even where the presence of humans is significantly reduced. Transitional environments between marine and freshwater environments, such as estuaries, are also affected by MPs [8][9][10]. The concentration of MPs in these environments is fairly variable and depends on several factors, such as the wind and current conditions, the geographical characteristics, the presence of urban areas and shipping trade routes [11], and the proximity to wastewater treatment plants (WWTPs) [12] and to abandoned, lost, or discarded fishing gear (ALDFGs) [13].…”

“…Estuaries are also contaminated with MPs. Estuaries are important aquatic ecosystems, since they represent a transitional zone between the sea and freshwater streams, playing an important role for several species and providing important ecosystem services [10,14]. Estuaries also provide an important tool for understanding the dispersion mechanisms of MPs [8].…”

The present work aims to evaluate the MP contamination of zooplankton and its impact on MP trophic transfers at the lower levels of the food web in a field study. During 1 year, seasonal surveys were conducted to collect zooplankton and water samples from different sites in two estuaries, the Douro and Lima estuaries (NW, Portugal). The zooplankton was quantified and identified into major zooplanktonic groups. Dedicated protocols that had been previously optimized were used to assess the MP presence in the water samples and in two of the most abundant zooplankton groups (copepods and chaetognaths). The results showed the presence of MPs in all water samples, with similar MP concentrations in both estuaries (Lima: 2.4 ± 2.0 MPs m−3; Douro: 2.3 ± 1.9 MPs m−3). In general, no temporal or spatial variations were observed. Fibres, blue and of a small size (<1 mm), were the most common characteristics of the MPs found in the water and zooplankton, indicating that water can be a source of MPs for zooplankton. Chaetognatha exhibited higher MP contamination in the Lima (2.9 ± 3.1 MPs ind−1) and Douro (2.0 ± 2.8 MPs ind−1) estuaries than Copepoda, which tended to have lower levels of MP contamination (Lima: 0.95 ± 1.12 MPs ind−1; Douro: 1.1 ± 1.2 MPs ind−1). Such differences in the MP concentrations between these two categories of zooplanktonic organisms indicate a possible MP trophic transfer at the lower levels of the food web. The results highlight the novel possibility of an MP trophic transfer in zooplankton and the need to fully assess the impacts of MPs in real scenarios.
