This problem has received increased attention worldwide, leading to the development of large-scale bioplastic plants. The large amount of MPs in aquatic and terrestrial environments and the atmosphere has raised global concern. This article delves into the profound environmental impact of the increasing use of petroleum-based plastics, which contribute significantly to plastic waste and, as a consequence, to the increase in MPs. We conducted a comprehensive analysis to identify countries that are at the forefront of efforts to produce bioplastics to reduce MP pollution. In this article, we explain the development, degradation processes, and research trends of bioplastics derived from biological materials such as starch, chitin, chitosan, and polylactic acid (PLA). The findings pinpoint the top 10 countries demonstrating a strong commitment to reducing MP pollution through bioplastics. These nations included the United States, China, Spain, Canada, Italy, India, the United Kingdom, Malaysia, Belgium, and the Netherlands. This study underscores the technical and economic obstacles to large-scale bioplastic production. <i>Integr Environ Assess Manag</i> 2024;20:1892–1911. © 2024 SETAC</p>","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":"20 6","pages":"1892-1911"},"PeriodicalIF":3.0,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141558708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

This initiative, supported by funding from the Brazilian Ministry of Justice and in partnership with academic institutions, has led to a concerted effort to establish ERA protocols for various taxa, including birds and mammals, soil organisms, aquatic organisms, and reptiles and amphibians. The outcomes of this initiative were disseminated in two distinct workshops held in February and November of 2023, where the agency showcased its research to the technical-regulatory community. This article synthesizes the proposals for birds and mammals and soil organisms. First, we summarize the agency's proposals for both focal and generic species to be incorporated into the ERA and the methodologies for calculating exposure of these taxa to pesticides through agricultural practices, encompassing seed treatment and foliar applications. On this occasion, IBAMA also disclosed the risk assessment tool that the agency is developing for birds and mammals. IBAMA highlighted the knowledge gaps that must be bridged to progress from preliminary (lower-tier) to more comprehensive (higher-tier) assessments. Regarding soil organisms, during the workshop, the presenters shared findings on the most prevalent species of earthworms and enchytraeids in Brazil. They emphasized the need for additional data collection on a regional scale. The agency has also proposed methods for estimating soil organism exposure to pesticides at a screening level and identified specific data gaps that could be addressed to refine assessments at higher tiers. In summary, the workshop communicated the progress in establishing ERA guidelines, which we encapsulate here to benefit the technical-regulatory community. <i>Integr Environ Assess Manag</i> 2024;20:1793–1799. © 2024 The Author(s). <i>Integrated Environmental Assessment and Management</i> published by Wiley Periodicals LLC on behalf of Society of Environmental Toxicology &amp; Chemistry (SETAC).</p>","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":"20 6","pages":"1793-1799"},"PeriodicalIF":3.0,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ieam.4975","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141491770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To simulate in situ microbial electrochemical treatment of groundwater plumes, this study investigates Cr(VI) reduction within a bioelectrochemical continuous flow (BECF) system equipped with soil-buried electrodes, comparing it to abiotic and open-circuit controls. Continuous-flow systems were tested with two chromium-contaminated solutions (20–50 mg Cr(VI)/L). Additional nutrients, buffers, or organic substrates were introduced during the tests in the systems. With an initial Cr(VI) concentration of 20 mg/L, 1.00 mg Cr(VI)/(L day) bioelectrochemical removal rate in the BECF system was observed, corresponding to 99.5% removal within nine days. At the end of the test with 50 mg Cr(VI)/L (156 days), the residual Cr(VI) dissolved concentration was two orders of magnitude lower than that in the open circuit control, achieving 99.9% bioelectrochemical removal in the BECF. Bacteria belonging to the orders <i>Solirubrobacteriales</i>, <i>Gaiellales</i>, <i>Bacillales</i>, <i>Gemmatimonadales</i>, and <i>Propionibacteriales</i> characterized the bacterial communities identified in soil samples; differently, <i>Burkholderiales</i>, <i>Mycobacteriales</i>, <i>Cytophagales</i>, <i>Rhizobiales</i>, and <i>Caulobacterales</i> characterized the planktonic bacterial communities. The complexity of the microbial community structure suggests the involvement of different microorganisms and strategies in the bioelectrochemical removal of chromium. In the absence of organic carbon, microbial electrochemical removal of hexavalent chromium was found to be the most efficient way to remove Cr(VI), and it may represent an innovative and sustainable approach for soil and groundwater remediation. <i>Integr Environ Assess Manag</i> 2024;20:2033–2049. © 2024 The Author(s). <i>Integrated Environmental Assessment and Management</i> published by Wiley Periodicals LLC on behalf of Society of Environmental Toxicology &amp; Chemistry (SETAC).</p>","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":"20 6","pages":"2033-2049"},"PeriodicalIF":3.0,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ieam.4972","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141491831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its coastal and marine domains are plagued by an excess of plastic waste. Vietnam has consistently discharged a substantial amount of waste into the oceans, ranging from 0.28 to 0.73 million metric tons annually. Numerous areas have emerged as focal points of plastic pollution throughout its extensive seashore and marine areas. The escalating presence of marine litter poses an increasingly grave threat to the intricate equilibrium of Vietnam's marine ecosystems. This comprehensive policy study reveals that the mounting problem of ocean plastic pollution, characterized by the abundance of floating plastic debris, imperils both plant and animal life, placing various marine species such as seabirds, fish, turtles, and cetaceans at risk. The consumption of minuscule plastic particles and the harmful impact of chemical pollutants from plastic waste in the ocean not only endangers the vitality of marine life but also poses a substantial hazard to human well-being because plastic waste infiltrates the food chain. This research reveals that, despite the existence of numerous laws and policies—including the Law on Environmental Protection 2020, the Marine Plastic Waste Management Initiative for the Fisheries Sector 2020–2030, and the National Action Plan for Management of Marine Plastic Litter—a significant amount of plastic waste is infiltrating the river network and eventually infiltrating oceans as a result of improper monitoring and ineffective enforcement of these legislations. Relying primarily on existing data released by the government and other sources and a wide range of gray literature retrieved from reputable databases, this study aims to evaluate the role of Vietnam's legal framework for combating the critical issue of marine plastic pollution in the South China Sea. <i>Integr Environ Assess Manag</i> 2024;20:2088–2106. © 2024 SETAC</p>","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":"20 6","pages":"2088-2106"},"PeriodicalIF":3.0,"publicationDate":"2024-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141456558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

In water, MSMA dissociates into ions of sodium (Na⁺) and of MMA⁻, which is the herbicide's active component. Certain soil microorganisms can methylate MMA to dimethylarsinic acid (DMA) other microorganisms can demethylate MMA to inorganic arsenic (iAs). To predict the groundwater concentration of iAs that may result from MSMA application, the processes affecting the environmental behavior of MSMA must be quantified and modeled. There is an extensive body of literature regarding the environmental behavior of MSMA. There is a consensus among scientists that the fate of MMA in soil is controlled by microbial activity and sorption to solid surfaces and that iAs sorption is even more extensive than that of MMA. The sorption and transformation of MMA and its metabolites are affected by several factors including aeration condition, temperature, pH, and the availability of nutrients. The precise nature and extent of each of these processes vary depending on site-specific conditions; however, such variability is constrained in typical MSMA use areas that are highly managed. Monomethylarsonic acid is strongly sorbed on mineral surfaces and becomes sequestered into the soil matrix. Over time, a greater portion of MMA and iAs becomes immobile and unavailable to soil microorganisms and to leaching. This review synthesizes the results of studies that are relevant for the behavior of MSMA used as a herbicide to reliably predict the fate of MSMA in its use conditions. <i>Integr Environ Assess Manag</i> 2024;20:1859–1875. © 2024 The Author(s). <i>Integrated Environmental Assessment and Management</i> published by Wiley Periodicals LLC on behalf of Society of Environmental Toxicology &amp; Chemistry (SETAC).</p>","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":"20 6","pages":"1859-1875"},"PeriodicalIF":3.0,"publicationDate":"2024-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ieam.4961","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141456555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In water, MSMA dissociates to ions of sodium (Na⁺) and monomethylarsonate (MMA⁻) that is stable and does not transform abiotically. In soils characteristic of MSMA use, several simultaneous processes can occur: (1) microbial methylation of MMA to dimethylarsinic acid (DMA), (2) microbial demethylation of MMA to inorganic arsenic (iAs), (3) methylation of iAs to MMA, and (4) sorption and sequestration of MMA and its metabolites to soil minerals. Sequestered residues are residues that cannot be desorbed from soil in environmental conditions. Sequestration is rapid in the initial several days after MSMA application and continues at a progressively slower rate over time. Once sequestered, MMA and its metabolites are inaccessible to soil microorganisms and cannot be transformed. The rate and extent of the sorption and sequestration as well as the mobility of MMA and its metabolites depend on the local edaphic conditions. In typical MSMA use areas, the variability of the edaphic conditions is constrained. The goal of this research was to estimate the amount of iAs potentially added to drinking water as a result of the use of MSMA, with models and scenarios developed by the US Environmental Protection Agency for pesticide risk assessment. In this project, the estimated drinking water concentrations (EDWCs) for iAs were assessed as the average concentration in the reservoir over a 30-year simulation with annual applications of MSMA at maximum label rates. When the total area of suitable land was assumed to be treated, EDWCs ranged from &lt;0.001 to 0.12 µg/L. When high estimates of actually treated acreage are considered, the EDWCs are below 0.06 µg/L across all scenarios. <i>Integr Environ Assess Manag</i> 2024;20:2076–2087. © 2024 The Author(s). <i>Integrated Environmental Assessment and Management</i> published by Wiley Periodicals LLC on behalf of Society of Environmental Toxicology &amp; Chemistry (SETAC).</p>","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":"20 6","pages":"2076-2087"},"PeriodicalIF":3.0,"publicationDate":"2024-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ieam.4962","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141456556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Home composting may be a more environmentally sustainable method of managing dog feces and reducing this pollution. While composting is an established method for recycling animal manures into low-risk soil conditioners for food production, few studies have investigated whether household-scale compost methods can safely and effectively process dog feces for use in backyard edible gardens. A broad range of literature on in situ composting of dog feces is evaluated and compared according to scale, parameters tested, and compost methods used. Studies are analyzed based on key identified knowledge gaps: appropriate compost technologies to produce quality soil conditioner on small scales, potential for fecal pathogen disinfection in mesophilic compost conditions, and biodegradation of compostable plastic dog waste bags in home compost systems. This review also discusses how existing methods and quality standards for commercial compost can be adapted to dog fecal home composting. Priorities for future research are investigation of household-scale aerobic compost methods and potential compost amendments needed to effectively decompose dog feces and compostable plastic dog waste bags to produce a good-quality, sanitized, beneficial soil conditioner for use in home gardens. <i>Integr Environ Assess Manag</i> 2024;20:1876–1891. © 2024 The Author(s). <i>Integrated Environmental Assessment and Management</i> published by Wiley Periodicals LLC on behalf of Society of Environmental Toxicology &amp; Chemistry (SETAC).</p>","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":"20 6","pages":"1876-1891"},"PeriodicalIF":3.0,"publicationDate":"2024-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ieam.4970","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141456557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This unsettling reality is becoming increasingly common as microplastics (MPs), plastic fragments smaller than a grain of rice (&lt;5 mm diam.), infiltrate our environment at an alarming rate. From the deepest trenches of the ocean to the peaks of mountains, these invisible invaders pose a significant potential threat to wildlife and even human health (Li et al., &lt;span&gt;2023&lt;/span&gt;; Zolotova et al., &lt;span&gt;2022&lt;/span&gt;). Microplastics are now recognized as a major contemporary global problem (Mitrano &amp; Wagner, &lt;span&gt;2021&lt;/span&gt;; Sendra et al., &lt;span&gt;2021&lt;/span&gt;), with a current estimate of 1.5 million tons of MP waste in the waterways globally (Boucher &amp; Friot, &lt;span&gt;2017&lt;/span&gt;).&lt;/p&gt;&lt;p&gt;Per- and polyfluoroalkyl substances (PFAS), often referred to as “forever chemicals” due to their persistence in the environment, present a hidden threat to human health (Fenton et al., &lt;span&gt;2021&lt;/span&gt;). These man-made chemicals, lauded for their water and stain-repelling properties, lurk unseen in a vast array of consumer products. However, their presence comes at a cost. Most recently (January 2024) method 1633, which created a stable and uniform approach for the analytical identification of PFAS, was approved by USEPA to identify 40 PFAS compounds. On 10 April 2024, the USEPA announced the final National Primary Drinking Water Regulation (NPDWR) for six PFAS (PFOA, PFOS, PFHxS, PFNA, PFBS, and HFPO-DA). This enables USEPA to establish legally enforceable levels, called Maximum Contaminant Levels, for six PFAS in drinking water.&lt;/p&gt;&lt;p&gt;In addition to being a primary source of pollution, MPs can also act as a carrier (via sorption and desorption) for other contaminants including PFAS. Some of the plastic types, including polytetrafluoroethylene and polyvinyl fluoride, can contribute PFAS directly to the environment. However, this is a very small contribution compared with the potential adsorption pathway via widespread MP pollution globally. This does not disregard PFAS concerns, as some authors have suggested (Lohmann et al., &lt;span&gt;2020&lt;/span&gt;). Rather, MPs might also increase the overall availability of PFAS in biosolids. As MPs degrade, they could release any absorbed PFAS, making them more bioavailable (available for uptake by organisms).&lt;/p&gt;&lt;p&gt;There are also concerns that MPs can be more efficient in adsorbing PFAS in the presence of other organic and inorganic matter, when compared with controlled environments, due to their large surface area and strong hydrophobic nature (Scott et al., &lt;span&gt;2021&lt;/span&gt;). The adsorption of PFAS to MPs was identified as thermodynamically spontaneous due to the increased entropy at 25 °C, based on Gibb's free energy (Δ&lt;i&gt;G&lt;/i&gt; = −16 to −23 kJ/mol), reaching equilibrium within 7–9 h (Salawu et al., &lt;span&gt;2024&lt;/span&gt;).
