“…A study by Rochman et al (2013) reported hepatic stress in fish because of the ingestion of plastic and transfer of hazardous chemicals. There are also reasons to believe that microplastics may carry microbes, including some pathogens, across large distances and, in turn, become agents of contamination in areas of high population density and low wastewater treatment infrastructure (Lu et al 2019).…”

“…The effects of small plastics and SVOC contamination on organisms may be complex (e.g., [82]) and remain largely uncertain, but knowledge of these effects is needed to understand the consequences of exposure to the organisms themselves and to others in the food web, including humans. While plastics are thought to largely pass through the guts of consumers, the extent of retention, degradation, interactions with gut microbiota, and subsequent health effects are only beginning to be realized [96][97][98][99][100], as are the effects of the plastic-associated contaminants (e.g., [100,101]). The acute and chronic effects of the three SVOCs found in this study have been observed on the growth, reproduction, enzyme activity, metabolic activity, respiration, kidney function and/or liver function in animals, while the effects on humans are less well known and are of concern [42,[66][67][68][102][103][104][105][106][107][108].…”

Natural history matters: Plastics in estuarine fish and sediments at the mouth of an urban watershed

The extent to which small plastics and potentially associated compounds are entering coastal food webs, especially in estuarine systems, is only beginning to be realized. This study examined an estuarine reach at the mouth of urbanized Chollas Creek in San Diego, California to determine: 1) the extent and magnitude of microplastics pollution in estuarine sediments and fish, 2) the extent and magnitude of SVOC contamination in estuarine fish, and 3) whether fish preferentially ingested certain types of microplastics, when compared with the microplastic composition of creekbed sediments. Surface sediments (0-5 cm depth) contained about 10,000 small plastic pieces per m 2 , consisting mostly (90%) of fibers, and hard and soft pieces. Nearly 25% of fish contained small plastics, but prevalence varied with size and between species. Of the 25 types of small plastics found in sediment, fish preferred about 10 types (distinct colors and forms). Several SVOCs, both water soluble and sediment-associated compounds, were found in the two species of fish tested. This study revealed that a species' natural history may influence contamination levels, and warrants further study to better understand the pathways of plastics and associated contaminants into and throughout coastal food webs, and the potential health risks for small and/or low-trophic level organisms.

“…In comparison to LDPE, PP and PS, which show hydrophobic characteristics, PA12 combines hydrophobic and hydrophilic surface groups (Schmidt et al, 2015), whereas microglass has a hydrophilic surface. A study by Marangoni et al (2018) showed that glass microspheres (4, 7-10 and 30-50 µm; microglass addition of 1 % v/v-5 % v/v) reduced the mobility of water reflected in a large decrease of the spin-spin relaxation time of water protons, decreased the self-diffusion coefficient of water molecules, lowered water activity and strengthened OH bonds. The study further showed that glass microspheres have an inhibiting effect on Escherichia coli growth and the germination of Medicago sativa seeds.…”

“…3). Based on the results by Marangoni et al (2018), it is conceivable that protozoa respond in a similar way to the presence of microglass, such as Escherichia coli. Nevertheless, these harmful effects of microglass particles on protozoa observed in our study are surprising because this indicates that, for example, sand grains in soil, which consist of SiO 2 , may also have inhibitory effects on protozoa.…”

Abstract. Microplastic and microglass particles from different sources enter aquatic and terrestrial environments. The complexity of their environmental impact is difficult to capture, and the consequences for ecosystem components, for example, the soil microorganisms, are virtually unknown. To address this issue, we performed an incubation experiment by adding 1 % of five different types of impurities (≤100 µm) to an agriculturally used soil (Chernozem) and simulating a worst-case scenario of contamination. The impurities were made of polypropylene (PP), low-density polyethylene (LDPE), polystyrene (PS), polyamide 12 (PA12) and microglass. After 80 d of incubation at 20 ∘C, we examined the soil microbial community structure by using phospholipid fatty acids (PLFAs) as markers for bacteria, fungi and protozoa. The results showed that soil microorganisms were not significantly affected by the presence of microplastic and microglass. However, PLFAs tend to increase with LDPE (28 %), PP (19 %) and microglass (11 %) in treated soil in comparison with untreated soil, whereas PLFAs in PA12 (32 %) and PS (11 %) in treated soil decreased. Interestingly, PLFAs revealed significant differences in PA12 (−89 %) and PS (−43 %) in comparison with LDPE. Furthermore, variability of bacterial PLFAs was much higher after microplastic incubation, while fungi seemed to be unaffected from different impurities after 80 d of incubation. Similar results were shown for protozoa, which were also more or less unaffected by microplastic treatment as indicated by the minor reduction in PLFA contents compared to the control group. In contrast, microglass seems to have an inhibiting effect on protozoa because PLFAs were under the limit of determination. Our study indicated that high amounts of different microplastics may have contrary effects on soil microbiology. Microglass might have a toxic effect for protozoa.
