“…The SW was fed into the SBR from a 25 L tank through a peristaltic pump. A second peristaltic pump drew off the effluent into the effluent sampling device (ESD) made of a 6 × 50 cm PVC tube (see (6) in Figure 1). The effluent, entering from the top of the tube, was filtered at the bottom through a removable metallic sieve (mesh size 150 µm).…”

“…Over the last decade, the focus on microplastics as emerging pollutants has seen a large increase on a global scale, resulting in a significant growth in the literature on the topic [3,4]. The main sources of MPs are the wear or breakdown of larger polymeric products, such as tires or artificial turf [5,6], the microfibers released from the washing of textiles [5,7], and the plastic particles used in manufacturing processes, such as air-blasting technology [1,8]. A recent study [7] estimated a release of 18 × 10 6 MP fibers for a household wash load of 6 kg of textiles made from synthetic fibers.…”

Assessment of Microplastics Distribution in a Biological Wastewater Treatment

Full-scale wastewater treatment facilities are not able to prevent microplastics (MPs) from discharging into natural waters and they are also associated with the land application of the sludge. This study evaluates the distribution of microfibers (MFs) in a lab-scale sequencing batch reactor (SBR) fed by synthetic wastewater (SW) for 93 days. The MFs were analyzed through optical microscopy in the mixed liquor (ML) and the effluent, and sulfuric acid digestion was applied to discriminate between natural and synthetic MFs (i.e., MPs). The results of the optical microscopy analyses were further validated through FTIR spectroscopy. A model describing the evolution over time of the MF concentration in the ML was created, accounting for the MFs entering the system through the SW and atmospheric deposition. The ratio between the MF concentration in the ML and the effluent was 1409 ± 781, demonstrating that MFs settle with the sludge. Consistently, in the ML, 64.9% of the recovered MFs were smaller than 1000 µm (average size 968 µm), while in the effluent, 76.1% of MFs were smaller than 1000 µm (average size 772 µm). Overall, 72% of MFs recovered from the ML were natural fibers and sulfuric acid digestion was successful in eliminating the natural MFs.

“…Therefore, MP particles-as carriers of chemicals, antibiotics, and heavy metals-they can ultimately deposit and accumulate in soil, marine, and freshwater sediments, being harmful to organisms [27,28] and infectious to urban wetlands/urban land uses [29]. In the relevant literature, the exact migration and transportation process applied from bacterial communities on MPs in estuarine areas remains unknown [30,31], while limited information is available on MPs' functionality on bacterial communities' dynamics, especially in urban water environments [32,33]. Since the specific density of plastics is close to that of water, synthetic litter in catchment areas is easily channeled from lakes and rivers, transported, and enters the open seas [34,35].…”

During the last decades, one of the most contentious environmental issues has been the investigation of the fate of microplastics (MPs) and detrimental consequences in natural and water resources worldwide. In this respect, it is critical research firstly to track the ways in which MPs are determined as key anthropogenic pollutants in terms of ecological risk and secondly to plan feasible policies under which the role of science and society in tackling this global issue in the future should be prioritized. In this study, a systematic theoretical, technical, and planning analysis was developed in alignment with a Scopus search deployed in the second half of the year 2021 and covering a wide chronological range (from 1970s onwards) and thematic contexts of analysis by using keywords and key phrases organized into two groups. The document results were graphically represented, revealing the main scientific focus of studies. Subsequently, our study investigated the quantitative assessment methods of MPs in marine environments, denoting the range of standard procedures applied for collecting and analyzing samples of water, bottom sediments, and coastal deposits. The technological part of the study includes the presentation of the relevant analytical techniques applied for MPs tracking and monitoring in water resources, determining the wide spectrum of plastic compounds traced. Of particular interest was the determination of environmental depletion and human implications caused, even by extremely low concentrations of MPs, for marine biota, posing potential risks to marine ecosystems, biodiversity, and food availability. Finally, the research proposed the challenges of actions needed to support scientific, industry, policy, and civil society communities to curb the ongoing flow of MPs and the toxic chemicals they contain into water resources, while rethinking the ways of plastics consumption by humanity.

“…(i) Application of microplastics through farming activities, including the use of sewage sludge [55,56], compost products [57], and irrigation with wastewater [58], all of which contain microplastics; (ii) Degradation of macroplastic items into microplastics from farming activities, such as plastic mulching films and greenhouse coverings/polytunnels used for crops [59,60]; (iii) Indirect application of microplastics via other activities such as open burning of plastic waste [16] and washing of clothes [61]; and (iv) Microplastic transfer from other environmental compartments and locations, such as freshwater bodies when flooded, and tire/brake and paint particulates from roads [62,63].…”

Plastic Pollution, Waste Management Issues, and Circular Economy Opportunities in Rural Communities

et al. 2021

Rural areas are exposed to severe environmental pollution issues fed by industrial and agricultural activities combined with poor waste and sanitation management practices, struggling to achieve the United Nations’ Sustainable Development Goals (SDGs) in line with Agenda 2030. Rural communities are examined through a “dual approach” as both contributors and receivers of plastic pollution leakage into the natural environment (through the air–water–soil–biota nexus). Despite the emerging trend of plastic pollution research, in this paper, we identify few studies investigating rural communities. Therefore, proxy analysis of peer-reviewed literature is required to outline the significant gaps related to plastic pollution and plastic waste management issues in rural regions. This work focuses on key stages such as (i) plastic pollution effects on rural communities, (ii) plastic pollution generated by rural communities, (iii) the development of a rural waste management sector in low- and middle-income countries in line with the SDGs, and (iv) circular economy opportunities to reduce plastic pollution in rural areas. We conclude that rural communities must be involved in both future plastic pollution and circular economy research to help decision makers reduce environmental and public health threats, and to catalyze circular initiatives in rural areas around the world, including less developed communities.
