“…Apart from BPPC2, the range of ∑16 PAH concentrations in this study was similar to that reported by Van et al (2012) with values ranging 240-1,700 ng/g-EPS in new EPS and 300-1,900 ng/g-EPS for beached EPS. Shi et al (2020) also reported a similar range of ∑16 PAHs with beached EPS collected from Shantou Bay ranging 81-7,714 ng/g. Li et al (2017) reported 8 PAHs with the lowest molecular weight among the 16 US EPA priority PAHs with a range of 311-534 ng/g and an average of 425 ng/g for PS food contact materials.…”

Among the plastic debris surveyed in the marine environment, a large quantity in terms of volume was found to be expanded polystyrene foam (EPS). This is due to its light weight and popularity as a packaging material. In this study, 28 compounds of polycyclic aromatic hydrocarbon (PAHs) were analyzed in both new and beached EPS collected in California, USA. In beached EPS, a variation in total PAH concentrations of up to 2 orders of magnitude was observed in the 337 to 11,800 ng / g-EPS range. Meanwhile, new EPS showed less variation in total PAH concentrations ranging from 282 to 1,194 ng / g-EPS. Most PAH species were shown to have higher concentrations in beached EPS than in new EPS, suggesting the ability of EPS to sorb PAHs from surrounding seawater. However, with anthracene, there was a significant depletion in beached EPS compared to new EPS. The fact that significant PAH concentrations were found in new unexposed EPS, including food packaging, highlights EPS as an exposure source of toxic chemicals to human food stocks upon migration, as well as to marine wildlife upon disposal. PAH concentrations and composition in new and beached EPS were consistent with those of samples from Japan, Malaysia and Australia, suggesting that the problems associated with EPS is a global issue.

“…According to van Sebille et al (2015) there are an estimated 51 trillion particles of microplastics floating on the surface of the ocean, and have been established as vectors for the transfer of persistent organic and inorganic contaminants including plastic additives (Benson and Fred-Ahmadu, 2020;Torres et al, 2021), organochlorine pesticides (O) (Shi et al, 2020), polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs) (Frias et al, 2010;Hirai et al, 2011;Fisner et al, 2013;Tan et al, 2019), and heavy metals (Turner and Holmes, 2015;Brennecke et al, 2016;Fred-Ahmadu et al, 2020a;Xiang et al, 2021). Microplastics and nanoplastics are composed of a variety of polymers that are hydrophobic, having varied molecular structures and characterized with the capability to adsorb organic pollutants and metals on interaction with them.…”

Micro(nano)plastics Prevalence, Food Web Interactions, and Toxicity Assessment in Aquatic Organisms: A Review

Plastic pollution is a fast-rising environmental catastrophe. Microplastics and nanoplastics (MNPs) are ubiquitous components of most aquatic environments, and their burgeoning prevalence is endangering aquatic organisms. Recent studies have documented the entanglement of marine and freshwater biota by plastic litters, particularly ghost fishing gear, resulting in suffocation, drowning, or starving to death. Numerous reports have shown that aquatic organisms readily ingest and accumulate these emerging contaminants in their digestive systems. Given experimental evidence that contaminants-laden MNPs can persist in the gastrointestinal tract for considerable durations, investigations have documented a high probability of lethal and sublethal toxicological effects associated with direct and indirect MNPs ingestions. These include chronic protein modulation, DNA damage, embryotoxicity, gastrointestinal toxicity, genotoxicity, growth inhibition toxicity, histopathotoxicity, liver toxicity, neurotoxicity, oxidative stress, reproductive toxicity, and tissue damage. Today, reports have proven the transfer of MNPs across the aquatic food web to humans. However, the mechanisms of multiple contaminants-laden MNPs-induced toxicities, size-dependent toxicity, and the comprehensive mode-of-action and alterations of digestive, reproductive, and neurological systems’ functionality in marine organisms are still unclear. Thus, this review mainly addresses the prevalence, food web interactions, and toxicity assessment of micro(nano) plastics in marine and freshwater organisms. It summarizes documented studies based on the following broad objectives: (1) the occurrence and prevalence of micro(nano) plastic particles in marine and freshwater environments; (2) the ingestion of MNPs by aquatic biota and the food web exposure routes and bioaccumulation of contaminated MNPs by higher trophic entities; (3) the adsorption and desorption of persistent organic pollutants, metals, and chemical additives on/from micro(nano)plastics; and (4) the probable ecotoxicological effects of micro(nano)plastics ingestion on aquatic biota.

Microplastic pollution in soils is a recent environmental problem and the lack of knowledge about the impacts and the extent of the problem are raising questions and concerns among researchers and politicians. Using a normative simulation model, we assess the extent of microplastic pollution in German agricultural soils originating from the land application of sewage sludge and compost. We estimate the microplastic concentration in German agricultural soils, the area of polluted land, and we compare the efficiency and effectiveness of some selected abatement measures. For 2020, we estimate that microplastic concentration in agricultural soil reaches a maximum concentration of between 30 and 50 mg/kg dry weight on 2% of Utilised Agricultural Area and a marginal concentration on 22% of Utilised Agricultural Area. Without the implementation of abatement measures, we expect the microplastic concentration to increase two to three times by 2060. Assessing the abatement measures, we find that for sewage sludge, thermal recycling is a more efficient and effective than equipping washing machines with microplastic-filters in private households. The use of plastic detection systems in the biowaste collection process reduces the plastic content of the compost and thus the release of microplastic into the soil. Detection systems are a more efficient measure for compost than thermal recycling. Concerning sludge, the findings indicate that the German strategy of thermally recycling sewage sludge is an efficient and effective measure to reduce microplastic pollution in soils. Reducing the plastic content of collected biowaste complies with the principles a circular economy.
