Dust suppressants constitute one effective means of dust control; however, research on dust suppressants has predominantly focused on characterizing their performance properties, with no systematic evaluations to date of their toxic effects on lung tissue. Therefore, through modification and response surface analysis, this study determined the optimal formulation for a composite dust suppressant to be as follows: 0.47 g modified guar gum, 0.24 mL rhamnolipid, and 5.36 g polyethylene glycol. Three toxic-exposure models were established to investigate the effects of dust and dust suppressants-both individually and in combination-on the lung tissue of C57BL/6 mice. The results indicated that low concentrations of dust suppressant (4 mg/m3) reduced total protein and immunoglobulin levels, thereby lowering mucosal infection risk; moderate concentrations (4-20 mg/m3) inhibited M1-type alveolar macrophage polarization and inflammatory factor expression (IL-6, TNF-α, etc.); and high doses (100 mg/m3) reduced the pulmonary fibrosis positivity rate from 11.31% to 1.30%, showing a tendency to reduce the probability of fibrosis. This study preliminarily complements the toxicological research system of dust suppressants and offers preliminary reference for the safe application of composite dust suppressants.","PeriodicalId":15671,"journal":{"name":"Journal of Environmental Science and Health Part A-toxic\\/hazardous Substances & Environmental Engineering","volume":" ","pages":"985-997"},"PeriodicalIF":2.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148375908","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}

The CRI classified low to moderate pollution risk at 60% of the sites, mainly at locations further from mining activities. Sites close to intensive mining and tailings accumulation presented exceptionally high pollution risk (CRI > 200). Elevated risk was driven primarily by As and Se in surface water and by Cd, Cu, Zn, and Se in soils.

KOH-activated carbon (AC-KOH) was one of the ready-prepared adsorbents and the one with the best physicochemical properties and adsorption capabilities. Under ideal testing conditions, the batch adsorption tests recorded a higher than 95% removal efficiency of As(V) and higher than 90% removal efficiency of As(III). The maximum adsorption capacity of AC-KOH reached 61.7 mg g-1 through isotherm modeling, which showed that this method exceeded all other activation methods. The adsorption process followed a pseudo-second-order model, which demonstrated that the main interaction mechanism involved chemisorption. The regeneration tests demonstrated that the system maintained consistent operation results throughout several adsorption and desorption cycles.

This review systematically evaluates heavy metal sorption onto environmentally relevant MPs, with particular emphasis on polyethylene terephthalate (PET), while also comparing polyethylene (PE), polypropylene (PP), polystyrene (PS), and selected modified polymers. A preferred reporting items for systematic reviews and meta-analyses (PRISMA)-guided framework was used to identify key studies for synthesis and mechanistic evaluation. The reviewed evidence demonstrates that adsorption behavior varies widely and is controlled primarily by environmental medium chemistry, metal speciation, and surface aging rather than polymer identity alone. PET frequently exhibits relatively high affinity toward Pb, Cd, and Co under freshwater and low-ionic-strength conditions, whereas marine environments commonly suppress sorption because of ionic competition and metal-ion complexation. Many studies reported pseudo-second-order kinetic behavior, indicating the importance of surface-controlled interactions on heterogeneous and oxidized MP surfaces. Despite emerging mechanistic consistency, substantial variability in experimental design, particle characteristics, and reporting approaches limits direct comparison among studies. Consequently, the proposed sorption hierarchy should be interpreted as a qualitative evidence-based framework rather than a statistically validated ranking. Overall, this review highlights MPs as environmentally conditioned and dynamic sorbents requiring standardized methodologies for more reliable ecological risk assessment.","PeriodicalId":15671,"journal":{"name":"Journal of Environmental Science and Health Part A-toxic\\/hazardous Substances & Environmental Engineering","volume":" ","pages":"855-884"},"PeriodicalIF":2.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148308281","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}
