The rapid global spread of SARS-CoV-2 and the resulting Coronavirus disease (COVID-19) pandemic has led to urgent efforts to contain and mitigate transmission. The useof face masks became a primary measure to limit the spread, which increased the production and consequentwaste generation. It is estimated that globally 129 billion single-use face masks are discharged into the environment every month. Besides to add to already great concerns over plastic pollution, contaminated face masks not properly handled also poses a health risk. The health and environmental consequences caused by the inadequate disposal of single-use face masks are treated in this study as an eminent risk to be properly communicated. This study framed the waste generation as a side impact of the COVID-19 pandemic and analysed how the communication has been made regarding the correct disposal of single-use masks, with focus in users of public transport in Stockholm region. National and regional authorities are recognized as the main responsibles for the communication about correct disposal, together with manufacturers and suppliers of single-use face masks. Disclosure and informative material of four government authorities and instruction manuals of eight brands of single-use face masks are analysed according to: i) presence / absence of information (about the disposal); ii) type of communication (visual or written); iii) message transmitted and; ix) availability in other languages.It was found guidance about correct disposal of face mask in two thirds of the existing communication, that is mainly written and with few visual aids. Half of communication is made only in Swedish and with no sufficient focus on the importance of correct disposal neither with reference to trash bins with lid. It suggests that the current communication about how to disposesingle-use masks safelymay not be enough, which is affecting the perception of risk by the population and worsening the health and environmental consequencescaused by the inadequate disposal.

Abstract In recent studies, many reports on the environmental effects of microplastic pollution have been presented. Countries across the world have already started carrying out studies on the restrictions of the industrial use of microplastics based on these reports. Many non-governmental organizations try to clean the existing microplastics from the oceans using their resources. However, a new source of microplastics has started to be released into nature as a result of the single-use face masks that protect us against the spread of COVID-19 and are being thrown onto the streets and into seas and nature. Before the pandemic, it was reported that more than 300 million microplastics were discharged from the province of Mersin to the eastern Mediterranean. This number will inevitably increase if not managed correctly. A mass balance needs to be studied for the correct management of waste. This study aims to estimate the amount of face mask use during the COVID-19 pandemic in Turkey, thereby expressing our concerns about waste management and plastic pollution, and calling on appropriate solid waste management policies and governments to take the necessary measures to formulate their strategies at all levels.

Abstract The face mask introduction in SARS-CoV-2 pandemic situation, one of the precautionary measure to reduce the rate of transmission of infection from person to person. There are many type of of face masks enter into our global market with various size and designs. Among those, surgical mask belongs to secure an important place and this aimed to evaluate the degrading efficiency disposable face masks (single use face masks). The present study dealt with, biodegradation of face masks which is made of polypropylene with the help of bacterial strainPesudomonasaeruginosaisolated from the plastic waste dumping sites in an around the Tiruchirappalli, India. The bacteriacould degrade PP mask via the formation of biofilm on a solid medium. To degrade the PP, the mask pieces were incubated with the culture of P. aeruginosain three different solid and liquid medium (nutrient agar, Bushnell Haas agar and mineral salt medium) for 30 days at 37ᵒC. The microbial degradation(up to 33% of weight reduction of PP films within 30 days) was proved by surface changes along with the variation in the intensity of functional groups as well as carbonyl index variations using Field-Emission Scanning Electron Microscopy (FE-SEM) and Fourier Transform Infra-Red Spectroscopy (FTIR) analysis. These results suggested that P.aeruginosa strain can prove to be a suitable candidate for polypropylene mask biodegradation without causing any impairment to our health or environment.

Objectives : Plastic pollution has been aggravated due to the massive use of disposable products and single-use face masks since the coronavirus disease (COVID-19) pandemic. There is growing interest regarding detection and identification of plastic pollution in daily life. The aim of this study is (1) to investigate suitability of a fluorescent labelling method for the detection of polymers, (2) to detect microplastics in personal care goods, and (3) to identify the detected plastic particles.Methods : In order to detect plastic particles in real samples, a 1-pyrenebutyric acid N-hydroxysuccinimidyl ester (PBN) fluorophore was used as a dye for staining plastic particles. First, the capability of PBN was evaluated by staining a model polymer of polyethylene (PE) particles, and its desorption and photobleaching was also investigated. Using the optimum staining condition, microplastics were detected in a laboratory-controlled sample and commercially available products, specifically in cleansers, scrubs, and toothpastes. Finally, the detected microplastics were identified using an attenuated total reflection Fourier transform infrared spectroscopy (ATR FT-IR) analysis.Results and Discussion : The PE particles fluoresced blue light after being stained with PBN at a concentration of 100 μg/mL for 3-5 min without post treatments (e.g., fixation and drying), but the particles should be detected within 24 h due to the photobleaching of PBN. The desorption of PBN fluorophore occurred when the stained PE particles were washed with 25% acetone rather than rinse-off with deionized (DI) water. All of the tested personal care goods contained plastic particles and various sizes and shapes (e.g., spherical, rounded, and irregular shapes) of particles were found in different types and brands of products. The detected particles were identified as PE, polypropylene (PP), polycarbonate (PC), ethylene vinyl acetate (EVA), polystyrene (PS), and polyvinyl chloride (PVC) polymers.Conclusions : The PBN was shown to effectively stain polymer particles and it allowed visual identification of microplastics in personal care goods. Various types and sizes of polymers were included into the commercially available products as ingredients, indicating a primary source of plastic pollution in aquatic environment.

Abstract The massive presence of plastic in the oceans, both in form of large debris and micro-plastic, is raising global concern due to its serious effects on the marine environment and fauna, causing loss of biodiversity and potentially threatening human health. Even though this is due to poor waste management, the great production and consumption of single-use plastic is a significant exacerbating factor. Despite policies and bans can be effective measures, there is also the need to raise consumers' awareness, so they can make more sustainable choices when purchasing, using and, dismissing products. In particular, educating young citizens and encouraging them to engage in pro-environmental behaviors is a fundamental task to reach this goal. In this work, we present Contact from the future, a digital game on plastic pollution for children, to create awareness and stimulate pro-environmental behaviors, discussing the definition of objectives and requirements, as well as the design and development of the application.

This article outlines the problem of waste accumulation as well as the associated environmental consequences in Ukraine due to the disparities between waste generation and utilization capacities. The analysis of quantitative parameters of waste generation sources and the territorial structure of Ukraine’s utilization capacities was carried out, and the spatial assessment of waste management system balance within regions was made. The work also identifies stages of territorially balanced management systems formation within the scope of current recycling technologies in the regional dimension. Methodological approaches to researching the balance conditions of waste management systems at the regional level are substantiated, which presupposes a mathematical model of these processes through the development of a system of equations, which depending on the tasks determine either the timing of the outlined phases of solving waste management issues based on available investment resources, or the amount of funds required to ensure proper timing of the innovative disposal facilities commissioning.

<p>The COVID-19 pandemic caused a massive use of disposable sanitary face masks. Based on data provided by Prata et al. (2020), we estimated that if only 0.1% of those masks are improperly discarded and enter the soil, approximately 361<sup></sup>t of polypropylene (PP) will be monthly added to the soil, threatening the ecological balance of terrestrial systems, the health of wild animals and even humans. For a first evaluation of the environmental consequences of the mask littering during COVID-19, we compared the microbial degradability of 10 x 10 mm cuts of the single masks layers and the complete mask blended with topsoil from a Cambisol of the Sierra de Aznalcóllar, Southern Spain with natural soil organic matter (SOM) by measuring the CO<sub>2</sub> release during a three-month decomposition experiment performed with a soil moisture of 75% of its maximal water holding capacity and at 25°C. In order to focus on biodegradation and to avoid abiotic impact of physical and chemical processes, the masks were not pretreated or exposed to UV-irradiation or natural daylight prior to decomposition. In addition, the incubation occurred in the dark. We identified an easily decomposable fraction with a mean residence time (MRT<sub>fast</sub>) of 2 to 3 days, releasing approximately 3 to 5% of the total mask carbon as CO<sub>2</sub>. Solid-state nuclear magnetic resonance (NMR) spectroscopy confirmed that all three layers of the mask were composed of PP without contributions of more than 2-3% of other additives. Microbial degradation resulted in a cut-off of terminal PP units as a main degradation mechanism. Assuming again that about 0.1% of the masks used during the COVID-19 crises may enter soil systems, we estimated that this fast pool may cause an additional CO<sub>2</sub> emission of 41 to 68 t year<sup>-1</sup>. This corresponds to the globally averaged annual CO<sub>2</sub>-footprint of 10 to 17 persons (4 t year<sup>-1</sup> person<sup>-1</sup>).  The slow turning fraction was mineralized with a rate constant of 0.05 to 0.14 year<sup>-1</sup> corresponding to a MRT<sub>slow</sub> between 7 and 18 years. This is two to four times longer than that determined for the SOM pure reference soil but still lies in the range reported for humified SOM derived from other topsoils of the Sierra de Aznalcóllar. Our results allow us to confirm our hypothesis that in soil, microbes exist that can decompose PP, although their nature still has to be revealed in future attempts. Studies investigating the impact of pre-exposure to daylight and moisture on their degradability in soils are in process.</p><p>Prata, J.C., Silva, A.L.P., Walker, T.R., Duarte, A.C., Rocha-Santos, T., 2020.

Background: The outbreak of COVID-19 has caused a devastating pandemic scenario in the world. The mortality rate has increased and new socio-economic challenges are emerging. Millions of gloves, gowns, face masks, and face shields are used daily to prevent airborne transmission and facilitate the treatment of COVID-19. Mismanagement of these wastes can lead to increased concerns due to their contamination potential. A comprehensive plan to improve the management of medical wastes in every country requires awareness of the current status of solid waste. As a result, the study aimed to calculate and estimate the consumption rate of face masks and medical waste generation rate during the COVID-19 pandemic in Iran. Also, the performance of different departments of medical waste management and future challenges are discussed. Methods: The daily consumption of face masks and medical waste generation were calculated based on the population data, the percentage of the urban population, face mask acceptance rate, the number of face masks needed per person per day, total COVID-19 confirmed cases, and medical waste generation rate (kg/bed/day). Results: The consumption of face masks in Iran is estimated at 46576000 pieces per day. Also, the three provinces of Tehran (9,560,000 pieces), Khorasan Razavi (3,825,600 pieces), and Isfahan (3,523,200 pieces) have the highest consumption rate of masks, respectively. Increasing the number of confirmed COVID-19 cases has increased the medical waste generation rate. Until April 3, 2021, more than 1,920,394 cases of COVID-19 have been confirmed in Iran, and calculations show that the medical waste generation rate in Iran is about 7,585.56 tons per day. Conclusions: COVID-19 is a highly infectious and problematic disease. The continuous increase in the number of confirmed COVID-19 cases has increased face mask consumption rate and medical waste generation rate, and as a result, new challenges have emerged in the field of solid waste management. These emerging challenges in managing solid waste during the COVID-19 pandemic necessitate the development of appropriate waste management policies and strategies.
