“…Table 3 shows the principal studies aiming to observe the effects of uptake of different MP types on freshwater benthic organisms, specifying the effect investigated and eventual evidence. The effects of MP intake in freshwater benthos is an important issue, since benthic invertebrates contribute up to 90% of fish prey biomass [133], and sediment becomes a sink of different organic and inorganic pollutants [134,135]. Therefore, bioaccumulation of MPs in sediment can enhance contaminant biomagnification.…”

Plastic is one of the most commonly produced and used materials in the world due to its outstanding features. However, the worldwide use of plastics and poor waste management have led to negative impacts on ecosystems. Plastic degradation in the environment leads to the generation of plastic particles with a size of <5 mm, which are defined as microplastics (MPs). These represent a global concern due to their wide dispersion in water environments and unclear potential ecotoxicological effects. Different studies have been performed with the aim of evaluating the presence and impacts of MPs in the marine environment. However, the presence of MPs in freshwater systems is still poorly investigated, making data retrieval a difficult task. The purpose of this review is to identify the main aspects concerning MPs pollution sources in lakes and rivers, with a focus on freshwater sediments as a site of accumulation and as the habitat of benthic organisms, which are key components of food webs and play a fundamental role in energy/contaminant transfer processes, but are still poorly considered. Through this review, the sources and fate of MPs in freshwater are analysed, ecotoxicological studies focused on sediments and benthic fauna are exposed, the most frequently used sampling and analysis strategies are reported, and future trends of MPs analysis in this field are proposed.

“…For example, the expression of stress response genes was elevated in the mussels from a less polluted area, and negatively correlated with the level of toxic metals (Kerambrun et al, 2016). Zebra mussels from the large deep perialpine lakes Maggiore and Lugano had low accumulation of toxicants (DDx, PCBs, and Hg), unlike in the fish from the same sites (Guzzella et al, 2018). Results of our study confirm that it is difficult to definitively evaluate site-related responses in the zebra mussel.…”

Hydropower plants (HPPs) are equipped with reservoirs that can accumulate the toxic effluents and disturb the water flow of rivers. The aim of this study was to evaluate the biochemical responses of zebra mussel Dreissena polymorpha inhabiting the reservoir of Riga HPP in comparison with the responses of the mussels from the natural lake Kanieris in Latvia. In the reservoir mussels, high Mn-SOD activity and low level of the lipid peroxidation (production of TBARS) in the soft tissues suggested an elevated antioxidant activity. Compared to the lake specimens, the reservoir mussels had low levels of RI GSH while their lactate/pyruvate ratio was 1.4 times higher. In the mussels from the reservoir, high level of protein carbonilation products, as well as lowered caspase-3 and extralysosomal cathepsin D activities (by 1.4 and 1.6 times respectively, compared to the lake specimens) indicated delayed apoptosis. Catalase and glutathione S-transferase activities and metallothionein concentration were similar in both groups. Vitellogenin-like proteins (detected as the alkali-labile phosphates) and cholinesterase levels were higher in the mussels from the reservoir. We chose the indexes of the redox capacity as the most suitable markers of the environmental impact on this organism.

“…No interaction between the considered variables (size and seasons) was evidenced by two-way-Anova test. The characteristic U-shaped trend of DDT and PCB concentrations in Lake Maggiore was observed since the beginning of the monitoring activities and it did not vary between years [33]. The inverse relationship between concentrations in zooplankton and zooplankton biomass might be associated with the shift in diet of zooplanktonic specimens because of the different availability of nutrient along the year.…”

“…Regarding Italian subalpine lakes, this is the first study of PFAS contamination in zooplankton, while data regarding DDT and PCB are abundant for Lake Maggiore [33], but sporadic for the other lakes. The last determination of DDT and PCB concentrations in zooplankton in Lake Iseo, dating back to 2010, showed that current DDT concentrations are lower, while PCB concentrations are stable [34].…”

“…In Italian lakes, which were studied in the present work, the seasonal trend was much stronger for the chlorinated compounds than for PFAS. Variations in PFAS were quite limited, as in the Gironde estuary, where PFAS only varied up to a factor of 2.5× for zooplankton and 2.3× for shrimps The characteristic U-shaped trend of DDT and PCB concentrations in Lake Maggiore was observed since the beginning of the monitoring activities and it did not vary between years [33]. The inverse relationship between concentrations in zooplankton and zooplankton biomass might be associated with the shift in diet of zooplanktonic specimens because of the different availability of nutrient along the year.…”

Zooplankton is a key node in many trophic webs, both for food that for persistent organic contaminants that can accumulate in biota. Zooplankton of different size was seasonally sampled for two years in three deep Italian subalpine lakes (Maggiore, Como, Iseo) with the aim of determining the concentrations of perfluoroalkyl substances (PFAS), DDT, and PCB, and assessing the seasonality impacts on contaminants concentrations. In general, Lake Maggiore showed the highest concentrations for each group of contaminants, with mean values of 7.6 ng g −1 ww for PFAS, 65.0 ng g −1 dw for DDT, and 65.5 ng g −1 dw for PCB. When considering the composition pattern, perfluorooctane sulfonate (PFOS) was detected in 96% of the samples and it was the predominant PFAS compound in all of the lakes. pp' DDE was the most detected congener among DDTs and their metabolites, while for PCBs, the prevalent group was hexa-CB that constituted 35.4% of the total PCB contamination. A seasonal trend was highlighted for all contaminant groups with concentrations in colder months greater than in spring and summer; it was evident that the contaminant concentrations were more dependent from seasonality than from size, trophic levels, and taxa composition of zooplankton. Principal component analysis showed that one of the main driver for the accumulation of most of the studied contaminants is their lipophilicity, except for perfluorooctanoic acid (PFOA) and octachlorobiphenyl.
