“…Other articles with 200 or more citations include Auta [65,66] discussing microbial MP degradation, as well as Edo [81], Conley [75] and Lv [119] discussing WWTPs. These results highlight the emphasis placed on interventions focused on the removal of MPs from wastewater (i.e., upstream interventions) globally, a trend evidenced by the large number of articles on wastewater treatment in this study (74.2%) and the voluminous number of articles on the removal of MPs from wastewater/sludge reviewed elsewhere [37,38,51].…”

“…Making decisions on the suitability of MP pollution control interventions for freshwater systems requires careful consideration of the location where they are to be applied and, more specifically, the catchment features. On this note, the definition of a catchment in the Anthropocene now accommodates the built environment as part of catchments, particularly in urban areas where stormwater runoff from buildings and roads [36], and other infrastructure such as wastewater treatment plants (WWTPs) [37,38] and ponds and reservoirs [39,40], can all receive and release MPs into natural water bodies, particularly freshwater systems such as rivers [41,42]. This threat has spurred increased implementation/commitment to policies, treaties and/or regulations focused on controlling MP pollution globally [43][44][45].…”

This systematic review represents one of the first attempts to compare the efficacy of the full suite of management interventions developed to control (prevent or remove) microplastics (MPs) in freshwater bodies, both man-made and natural. The review also traces the evolution of research on the topic in relation to the timing of key policy and regulatory events and investigates whether interventions are being applied within regions and freshwater bodies that represent concerns in terms of MP pollution. The review incorporated bibliometric analysis and meta-analysis of 124 original research articles published on the topic between 2012 and April 2023. To supplement the key findings, data were extracted from 129 review articles on the major knowledge gaps and recommendations. The number of articles on the topic increased with each year, coinciding with a range of global policy commitments to sustainability and mitigating plastic pollution. The majority of the studies focused on MPs in general, rather than any particular particle shape or polymer type, and were conducted at wastewater/sludge treatment plants. Upstream interventions accounted for the majority of studies reviewed (91.1%). A smaller proportion (4.8%) of studies involved reduction in production and physical removal at the point of production (1.6%); treatment-related objectives such as removal through filtration and separation and the combination of these with other technologies in hybrid systems were dominant. Of the physical, chemical and biological methods/technologies (and combinations thereof) employed, physical types (particularly membrane filtration) were most common. The majority of the studies within the wastewater/sludge, stormwater and in situ water/sediment categories exhibited removal efficacies >90%. Although new interventions are constantly being developed under laboratory conditions, their scalability and suitability across different settings are uncertain. Downstream interventions lack sustainability without effective upstream interventions. Though in situ methods are technically achievable, they may not be feasible in resource-limited settings.

“…Researchers widely discussed negative impacts of MP on the environment and human health. However, the precise effects of MP on the biosphere are not well understood scientifically yet [13], probably due to several challenges such as; inconsistency of physical and chemical properties of MP, multiple sources of origin, multiple pollution pathways, insufficient availability of detection, and other laboratory methods [14,15]. The fundamentals in data collection standards, quality control, data storage, data sharing, and reporting ought to be improved to compare and merge MP related data from all over the world [16].…”

The emergence of microplastics (MP) as a pollutant in natural environments including aquatics has been increasingly recognized worldwide. This review focuses on the status of MP pollution research in Sri Lanka, and MP risk mitigation solutions, as lessons from a global MP policy context. The methodology involves a comprehensive literature review divided into three main sections: 1) a simple understanding of the plastic cycle and risk factors,2) a comprehensive review of MP pollution research trends in Sri Lanka, 3) a comprehension of global trends of MP regulation policies and adaptable solutions for national scale. There was less attention given to MP research in Sri Lanka, until the recent X-Press Pearl disastrous incident. In addition to that, we highlight the less attention paid to MP pollution in inland waters and lands compared to marine. Considering the widespread MP issue, the paper highlights the importance of a policy approach for MP pollution control. Finally, the paper discusses the future directions for MP pollution research in Sri Lanka and emphasizes the need for more detailed quantitative data for effective policy formulation. The overall study presents a sound case for understanding a national context in MP pollution and suggesting necessary policy instruments in pollution regulation.

“…New groups of emerging pollutants have been detected in the aquatic environment, with microplastics (MPs) receiving significant attention in recent years. Due to their durability and increasing global usage, plastics have become ubiquitous environmental pollutants Water 2023, 15, 3890 2 of 16 in both soil and aquatic (both marine and freshwater) environments [8][9][10]. According to the most common definition, MPs are particles ranging in size from 1 to 5000 µm [10][11][12].…”

Do Microplastics Affect the Photodegradation of Duloxetine and Its Phototoxicity to Protozoan Spirostomum ambiguum (Müller, 1786) Ehrenberg, 1835?

As contaminants are often present in aquatic environments as mixtures, they may interact with each other and affect living organisms differently than when tested individually. Emerging pollutants such as pharmaceuticals and microplastics can be influenced by various environmental factors, with UV/Vis radiation being among the most significant. This study aimed to evaluate the photodegradation of the antidepressant duloxetine in the presence of four types of microplastics. Acute toxicity was tested using the Spirotox assay, duloxetine concentration was determined using HPLC-DAD analysis, and the resulting photodegradation products were tested using HPLC-MS/MS. Following 1 and 2 h of exposure in a sunlight simulator, the concentrations of duloxetine decreased by nine and thirteen times, respectively, while its toxicity to protozoa decreased by only two and three times. The presence of microplastics in the samples did not affect either the photodegradation process or the toxicity of duloxetine. HPLC-MS/MS analysis revealed the presence of 34 duloxetine photodegradation products. In silico toxicity analysis using the T.E.S.T. program for the protozoan Tetrahymena pyriformis indicated that one-third of the photoproducts were as toxic, and two products were found to be much more toxic than duloxetine. The high toxicity of one of these compounds was confirmed using the Spirotox test.
