“…The functional groups of NPs influenced their toxicities to zooplankton in fresh water and seawater (Saavedra et al, 2019;Kim et al, 2020;Gola et al, 2021). PS-NH 2 NPs enhanced the gonad development, the reproductive capacity, and the genotoxicity to nematode (Caenorhabditis elegan) compared with bare PS NPs and PS-COOH NPs (Qu et al, 2019;Kim et al, 2020;Yilimulati et al, 2020;Schultz et al, 2021).…”

Nanoplastics (NPs) are ubiquitous in harvested organisms at various trophic levels, and more concerns on their diverse responses and wide species-dependent sensitivity are continuously increasing. However, systematic study on the toxic effects of NPs with different functional group modifications is still limited. In this review, we gathered and analyzed the toxic effects of NPs with different functional groups on microorganisms, plants, animals, and mammalian/human cells in vitro. The corresponding toxic mechanisms were also described. In general, most up-to-date relevant studies focus on amino (−NH2) or carboxyl (−COOH)-modified polystyrene (PS) NPs, while research on other materials and functional groups is lacking. Positively charged PS-NH2 NPs induced stronger toxicity than negatively charged PS-COOH. Plausible toxicity mechanisms mainly include membrane interaction and disruption, reactive oxygen species generation, and protein corona and eco-corona formations, and they were influenced by surface charges of NPs. The effects of NPs in the long-term exposure and in the real environment world also warrant further study.

“…Microplastics have been found also in freshwater [16], drinking water [17], soil [18] as well as in food articles [19]. It has been demonstrated that there are adverse impacts of microplastics on aquatic and soil living organisms due to impaired reproduction, malnutrition, internal abrasions, and blockages [20][21][22], and also adverse human health impacts have been identified [23][24][25]. Considering their high surface area and hydrophobicity of their surfaces, microplastics can act as sorbents for other environmental pollutants, persistent organic pollutants [26], hydrocarbons [27], pharmaceuticals [28] and other pollutants [29].…”

Microbial Life on the Surface of Microplastics in Natural Waters

et al. 2021

Major water-polluting microplastics (for example, polyethylene, polypropylene and others) have lower density than water. Therefore, they are concentrated in the neustonic layer near the water-air interface altogether with dissolved or colloidal natural organic matter, hydrophobic cells and spores of bacteria. This can cause environmental and public health problems because the floating micro- and nanoparticles of plastics could be coated with biofilm of hydrophobic and often putative pathogenic bacteria. Biofilm-coated microplastics are more attractive for consumption by aquatic animals than pure microplastics, and that increases the negative impacts of microplastics. So, impacts of even small quantities of microplastics in aquatic environments must be accounted for considering their accumulation in the micro-layer of water-air interphase and its interaction with bacterioneuston. Microorganisms attached to the surface of microplastic particles could interact with them, use them as substrates for growth, to change properties and biodegrade. The study of microbial life on the surface of microplastic particles is one of the key topics to understanding their role in the environment.

“…As one of the most important materials in the 21st century, plastics have an impact that cannot be underestimated on our society and daily life [ 1 , 2 , 3 ]. Since the 1950s, a variety of plastic products have continued to be released, and the output of plastics has increased exponentially.…”

“…Due to the large-scale production and poor management of plastics in the past few decades, most plastic products are discarded after use, and only 6–26% are recycled and landfilled [ 5 , 6 ]. Large amounts of plastic waste migrate to the ocean with surface runoff and float, deposit or accumulate in coastal waters such as estuaries and bays [ 2 , 3 , 7 ]. It is estimated that 6–12 million tons of plastic enter the ocean every year, and more than 250 million tons of plastic will accumulate in the ocean by 2025 [ 8 , 9 ].…”

“…It is estimated that 6–12 million tons of plastic enter the ocean every year, and more than 250 million tons of plastic will accumulate in the ocean by 2025 [ 8 , 9 ]. Plastic products have become the main component of marine garbage, accounting for about 60–80% of its total, and even as high as 95% in some areas, which causes serious pollution to the marine environment [ 2 , 3 , 10 ].…”

Microplastics (MPs) are ubiquitous in environmental media, and their harmful effects on MPs on the ecosystem have attracted more and more attention. Once released into the environment, MPs can trigger oxidative degradation through ultraviolet (UV) to cause photoaging. Photoaging significantly affects the properties of MPs, which leads to changing their environmental behaviors and increasing environmental risks. In this review, the generation of MPs under UV irradiation and the influence of environmental factors on the photoaging of MPs were discussed. Photoaging of MPs is an important process affecting the migration, transformation and interaction of pollutants in water and soil. In order to fully predict the fate and environmental interaction of MPs, more researches are needed in the future to explore the photoaging behavior of different types of MPs under natural environmental conditions.
