“…These deleterious effects may lead to decreased fitness (Fonte et al, 2016; Naidoo and Glassom, 2019). In addition, biofilm on surfaces of MPs lead to sinking and facilitate adhesion of metals, such as Cd, Hg, and Cu (Djaoudi et al, 2022; Richard et al, 2019; Turner and Holmes, 2015), and organic pollutants such as polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) (Rochman et al, 2013). Ions within biofilms are less tightly bound and easily desorbed (Kurniawan et al, 2012).…”

Numerous recent studies have documented ingestion of microplastics (MPs) by many aquatic animals, yet an explanation for misfeeding by fish remains unexplained. Here we tested the hypothesis that biofilm (biofouling) on MP surfaces due to exposure in the aquatic environment facilitates misfeeding in fish. Spherical polystyrene (PS) was cultured for 0 to 22 weeks in a freshwater environment to grow biofilm on the MP. Goldfish were employed in a simple feeding experiment with and without provision of genuine food at ecologically relevant MP concentrations. The absorbance (ABS), which is a proxy for biofilm formation increased exponentially within three weeks of initiation and reached a plateau after approximately five weeks. Although fish did not swallow the MPs, 'capture' occurred when food pellets were in the vicinity and significantly increased in probability with exposure time. Duration of capture also increased significantly with increasing exposure. These results suggest that the drift of MPs in aquatic environments may facilitate fish misidentification of MPs as edible prey.

“…As suggested by the World Health Organization (WHO) as well as Directive 98/83/CE of the European Union, the health-based guideline value of copper in drinking water is 2 mg/L [4,5]. In addition to the harmful effects on human health, copper may also pollute the marine environment and impact the functioning of ecosystems, due to, for example, its use as a biocide in marine antifouling paints [6,7]. In this context, the interest in the monitoring of copper in environmental waters has immensely increased during the last few decades.…”

There is a strong interest in monitoring copper in environmental waters, but its direct analysis suffers from strong matrix interferences. This is why, a sample pretreatment based on solid‐phase extraction (SPE) is often used but conventional sorbents usually lack specificity. It is overcome with ion‐imprinted polymers (IIPs). This work evaluates for the first time the use of the dummy approach for the synthesis of Cu(II)‐targeting IIPs. Two analog ions Ni(II) and Zn(II) were tested as templates and the resulting IIPs were packed in SPE cartridges. The SPE procedure was designed by optimizing a washing step following the sample percolation, to eliminate the interfering ions retained on the IIP by non‐specific interactions. To optimize the washing step, solutions at different pH or containing tris(hydroxymethyl)aminomethane as a complexing agent at different concentrations were tested and combined. Zn‐IIP appeared more promising than Ni‐IIP, showing excellent specificity and a high selectivity. Its retention capacity was determined to be 100 µg/g, and different isotherm models were evaluated to fit with the adsorption data. Finally, applications to mineral and sea waters were successfully completed and led to high and repeatable extraction recoveries for Cu(II) (88 ± 1% and 83 ± 3%, respectively).
