There is also growing evidence that microplastics exert negative effects on biota and ecosystems. Biodegradable plastics may represent a safe alternative, yet their potential adverse effects have not been comprehensively analyzed. Here, we reviewed biodegradable plastics, with focus on their conversion into microplastics, their interactions with pollutants, and their combined toxicity for aquatic biota. Biodegradable plastics include polylactic acid, polyhydroxyalkanoates, polybutylene succinate, poly(butylene adipate-<i>co</i>-terephthalate), and poly(ε-caprolactone). We found that some biobased plastics are hardly biodegradable. Some biobased plastics are compostable but require specific environmental conditions for their biodegradation. Biobased plastics can generate microplastics when released into the environment, which can impact biota. Contrary to the common public belief, biodegradable plastics may not only originate from biosources but can be synthesized from fossil fuels. Microplastics originating from biodegradable plastics can interact with pollutants, adsorbing and transporting these pollutants, resulting in synergistic or antagonistic effects on exposed organisms. Biofilm formation on microplastics impacts their degradation and pollutant interactions.</p></div>","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"22 3","pages":"1185 - 1220"},"PeriodicalIF":15.0,"publicationDate":"2024-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139976714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The unique mixed solution of Ru<sup>IV</sup>-Fe<sup>VI</sup> had less resistance to perform the catalytic reaction.

Mathematical modeling can also determine the effects on the performance of parameters such as diffusion layer thickness, flow velocity, applied current density, solution treatment time, initial concentration and diffusion coefficients of organic pollutants, electrode surface area, and oxidation reaction rate constant. Mathematical models allow to determine whether the limiting factor of the process is kinetics or diffusion, and to study the impact of competition of phenomena.

They contribute to the production of reactive oxygen species in environmental media, leading to oxidative stress in biological organisms. This stress can provoke inflammation and damage to biological macromolecules, potentially resulting in cardiopulmonary dysfunction. In this review, we discuss the formation and classification of EPFRs. Typically, EPFRs form through electron transfer from organic compounds to transition metals during thermal processes. In metal-free environments, however, organic compounds can undergo bond cleavage, generating EPFRs under thermal conditions and light exposure. EPFRs are generally categorized into three types: oxygen-centered, carbon-centered, and those containing heteroatoms centered on either oxygen or carbon. We also provide a detailed summary of the fundamental characteristics of EPFRs in different environments such as air, soil, and water. Given their role as electron donors, EPFRs have potential applications in degrading organic pollutants in the environment. The review comprehensively addresses the deleterious impacts of EPFRs on organism health, highlighting risks to metabolic functions and cardiopulmonary health. Furthermore, it underscores the potential involvement of EPFRs as electron donors in atmospheric chemical reactions. The pivotal role of EPFRs in environmental pollutant transformation warrants more studies in future research endeavors.</p></div>","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"22 3","pages":"1327 - 1343"},"PeriodicalIF":15.0,"publicationDate":"2024-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139750215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
