Since then, microplastics have been found in aquatic and terrestrial environments, the atmosphere, and inside the bodies of animals and human beings, including human lungs. The plastic particles’ contribution to environmental pollution is extensive, accounting for millions of metric tons of waste in the oceans and on land. As the world grapples with extensive microplastic pollution, significant progress is being made in preventing and addressing it. To this end, green microbiology has emerged as a potential approach for microplastic remediation. This article evaluates research on the viability of the use of microorganisms for this purpose, highlighting some microorganisms that have been used successfully in the remediation of microplastics, the mechanisms employed for this purpose, and the link of their use for microplastic remediation to sustainability. Finally, this article builds on current knowledge to identify potential future directions for research on the use of microorganisms for microplastic remediation.</p></div>","PeriodicalId":34473,"journal":{"name":"Environmental Advances","volume":"17 ","pages":"Article 100569"},"PeriodicalIF":0.0,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666765724000875/pdfft?md5=d5a55718cb454a99e73957c099dfd059&pid=1-s2.0-S2666765724000875-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141729695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the main hurdles in the quantification of such ecosystem services is associated with the difficulty to obtain and design systems that provide detailed information on the interaction between various gases and the plant in question. To tackle these questions, two highly precise and accurate instruments, namely a mid-infrared laser absorption spectrometer (TDL) and a cavity-ring-down spectrometer (CRDS) were used to monitor the fate of gases when exposed to façade climbing plants like ivy. In a laboratory setting, a relaxation type of experiment was used consisting of a reaction chamber equipped with plant species and continuously flushed by synthetic air. This setup was used to determine the timescales of decay after short injections of the above-mentioned gases. After these injections, all gases followed simple exponential decay curves. N₂O, a non-reactive (inert) tropospheric gas, was used as a reference to which all other gases were compared and thereby quantified. This paper focuses on the detailed description of methods and processes to analyse the gas-absorptive behaviour of plants when exposed to gaseous pollutants. For demonstration purposes, quantified absorption features of nitrogen oxide (NO₂) are presented for ivy of the variety <em>Hedera helix</em> “Plattensee”. Results of this method of quantification showed that - as compared to N₂O (control), - NO₂ had a reduced residence time (time scale) of 100 s, while N₂O resulted in a 600 s residence time (indicating no interference with the plant). This is equivalent to a 0.3 cm/s deposition velocity/ absorption rate of NO₂ under light conditions.</p></div>","PeriodicalId":34473,"journal":{"name":"Environmental Advances","volume":"17 ","pages":"Article 100568"},"PeriodicalIF":0.0,"publicationDate":"2024-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666765724000863/pdfft?md5=0097c9dc6b93c81daceee15d03a348dd&pid=1-s2.0-S2666765724000863-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141637804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluates the impact of MPs on the decolorization of Reactive Red 239 (RR239) dye using hydrogen peroxide–based advanced oxidation processes, specifically UV/H₂O₂, H₂O₂/Fe²⁺ (Fenton) and H₂O₂/Fe²⁺/UV (photo–Fenton). UV/H₂O₂ oxidation exhibited superior decolorization efficiency compared to both Fenton and photo–Fenton processes. The optimal decolorization efficiency for RR239 was achieved at 94.1% at pH 3 in the Fenton process with H₂O₂ and Fe²⁺ concentrations of 2.5 mg/L and 12.5 mg/L, respectively. For UV/H₂O₂ oxidation, complete decolorization was achieved in 60 min at an optimal UV light intensity of 11 W and H₂O₂ of 75 mg/L at neutral pH. The presence of spunbond nonwoven MPs in RR239 wastewater significantly inhibited decolorization efficiency and kinetic rate constants. The pseudo–second–order rate constant (<em>K_app</em>) for the Fenton process without MPs was 0.0101 M^–1 min^–1, whereas the presence of MPs reduced the <em>K</em>_<em>app</em> to a range of 0.0026 to 0.0034 M^–1 min^–1. The UV/H₂O₂ process maintained a <em>K_app</em> of 0.1301 min^–1 as pseudo–first–order regardless of MP content but was affected by MP size. MPs in the size range of 200–500 µm improved decolorization efficiency, while larger MPs (500–1000 µm) reduced it. The results highlight the necessity of separating MPs to maintain high decolorization efficiency in dye wastewater treatment processes. The findings suggest that optimizing these parameters can enhance the efficacy of advanced oxidation processes in treating dye wastewater containing MPs.</p></div>","PeriodicalId":34473,"journal":{"name":"Environmental Advances","volume":"17 ","pages":"Article 100567"},"PeriodicalIF":0.0,"publicationDate":"2024-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666765724000851/pdfft?md5=4a6135cf15b3e4a9d93dd5bcbc257500&pid=1-s2.0-S2666765724000851-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141701028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, to be able to produce environmental relevant ecotoxicity data, laboratory tests should take these properties into consideration as well as in the calculation of effect factors for the Life Cycle Assessment methodology. In this study, we reviewed papers estimating ecotoxicity of microplastics ingested by species under laboratory conditions as well as data on microplastics ingested by species sampled from the field. This aims to identify the physical property of the plastics ingested and the influence on levels of ecotoxicity. Afterwards, our paper shows a mismatch between the physical properties ingested by the species sampled in the field and those tested for toxicity in laboratory studies. Regarding types, laboratory studies commonly expose aquatic species to regularly shaped particles such as microbeads and pellets (representing 72 %). For effect factors in LCA context, microbeads represent 88 % in number of datapoints. In contrast to this, irregularly shaped particles (e.g. fibres and fragments) are more frequently reported in the field, representing 85 % of the ingested microplastics. At the same time, regarding size, most of the laboratory studies examine microplastics and there is a lack of toxicity data for nano sized particles. A mismatch is also reported on the polymers; Polypropylene, Polyethylene and Polyester represented a total of 45 % of the samples detected in the field, while Polyethylene and Polystyrene represent 69 % in ecotoxicity studies and 78 % in effect factors. These mismatches shows that physical properties prevalent ingested by the species still lack data on levels of ecotoxicity as well as in number of data points in the LCA context.</p></div>","PeriodicalId":34473,"journal":{"name":"Environmental Advances","volume":"17 ","pages":"Article 100566"},"PeriodicalIF":0.0,"publicationDate":"2024-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S266676572400084X/pdfft?md5=faba8a27fd1c22ee437ae0857feaf2a5&pid=1-s2.0-S266676572400084X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141605917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
