“…For such samples, the matrix should be eliminated or even reduced i.e. by oxidation of organic compounds with 30% hydrogen peroxide (Sighicelli et al 2018), 70% ethanol (Free et al 2014), 95% ethanol (Eriksen et al 2018), 100% ethanol (Barnes et al 2010) or with 70% isopropyl alcohol (Eriksen et al 2013(Eriksen et al , 2018.…”

“…Behind the hole, there is an attached a plankton or neuston net with a mesh diameter of usually 300-335 μm. The structure is placed on the surface of water in such way that the upper water layer gets to the net (Moore et al 2011, Faure et al 2012, Eriksen et al 2013, Free et al 2014, Davis & Murphy 2015, Dris et al 2015b, Eriksen et al 2018, Li et al 2018, Sighicelli et al 2018, Wagner & Lambert 2018. In the presented research, this solution was not applied, due to the relatively clean water -floating waste was not observed (except for a few plastic bottles in the Rudawa River).…”

The results of research conducted in recent years indicates that microplastic particles are widely distributed in the aquatic environment. The investigations are mostly focused on marine waters and there is still a lack of information about their presence in both surface water and groundwater. In this paper, preliminary results of research conducted in Poland are presented. Different types of water samples were collected. Five litres of each sample were filtered through 0.4 μm glass fibre filters. In the first stage, visual identification was conducted using a stereomicroscope. Additionally, some interesting fragments were examined by means of SEM/EDS method. In the case of rivers water samples, which were characterized by a high content of organic matter and minerals, the visibility of microplastics could be reduced. In the sample from the Vistula River, some particles similar to microplastics were found. In the groundwater samples, some blue and green particles which supposed to be plastic were found by the stereomicroscope. Additional analysis with the DXR Raman Microscope method gave no clear results. The samples were too small and the plastic particles were very dispersed which prevented correct analysis. SEM analysis showed irregularly shaped particles which were considered to be microplastics. Considering the chemical composition, carbon predominated.

Nano- and microplastics affect the composition of freshwater benthic communities in the long term

et al. 2020

Given the societal concern about the presence of nano- and microplastics in the environment, our nescience with respect to in situ effects is disturbing. Data on long-term implications under ecologically realistic conditions are particularly important for the risk assessment of nano- and microplastics. Here, we evaluate the long-term (up to 15 months) effects of five concentrations of nano- and microplastics on the natural recolonization of sediments by a macroinvertebrate community. Effects were assessed on the community composition, population sizes and species diversity. Nano- and microplastics adversely affected the abundance of macroinvertebrates after 15 months, which was caused by a reduction in the number of Naididae at the highest concentration (5% plastic per sediment dry weight). For some other taxa, smaller but still significant positive effects were found over time, altogether demonstrating that nano- and microplastics affected the community composition.

“…Microplastics (MPs) continue to proliferate in marine, freshwater and terrestrial ecosystems, with biotic impacts frequently unknown (Sighicelli et al, 2018). Microplastic pollution has been detected from the poles to the deep ocean, and more recently in bottled drinking water (Mason et al, 2018;Wagner and Lambert, 2018).…”

Microplastics (MPs) continue to proliferate and pollute aquatic and terrestrial environments globally. The impacts of MP pollution on ecosystems and their functioning remain poorly quantified, with most research hitherto focusing on marine ecosystems. There is a paucity of information on the impacts of MPs in freshwater ecosystems, despite the broad range of pathways through which MPs can proliferate and the extensive range of species which actively ingest MPs in these systems. Of particular interest are organisms that bridge aquatic and terrestrial habitats. The present study thus examines the uptake, ontogenic transference and effect of different concentrations (0, 50, 100 and 200 MPs mL-1) and sizes (2 and 15 µm) of polystyrene MPs between aquatic and terrestrial life stages of Culex pipiens complex mosquitoes. Both 2 and 15 µm MPs transferred from the aquatic larval to terrestrial adult stage of Culex mosquitoes, and uptake correlated tightly with initial exposure concentration. However, neither concentration nor size of MPs significantly influenced mortality rates between the aquatic larval and terrestrial adult stage. There was also no impact of MPs on the weight of emerging mosquito adults. We thus demonstrate that MPs can be transferred ontogenically through organisms with complex life histories, presenting a potential pathway for dispersal of MPs into terrestrial environments. We also show that MPs exposure does not affect mortality rates between life stages of freshwater Culex populations. This suggests that MPs do not impact nutritional uptakes, with unhampered development to adulthood facilitating subsequent dispersal of MPs aerially and between freshwater and terrestrial habitats.
