While numerous adsorbents have been explored, the development of materials that are simultaneously low-cost, biodegradable, thermally stable, and derived entirely from renewable feedstocks remains an unmet challenge. Elemental sulfur, an abundant industrial by-product with unsaturated vegetable oils, offers a promising route to bio-based, sulfur-rich adsorbents. In this study, four sulfur-oil copolymers were synthesized by inverse vulcanization of elemental sulfur with safflower oil (S-S) and linseed oil (S-L), with and without sodium chloride (NaCl) as a salt-templating porogen to produce porous variants S-S-N and S-L-N. Fourier transform infrared spectroscopy confirmed successful S-C bond formation and consumption of olefinic double bonds in oil, while thermogravimetric analysis demonstrated that NaCl-induced porosity and higher oil unsaturation synergistically enhanced thermal stability, with S-L-N exhibiting the highest decomposition temperature (551 °C). A scanning electron microscope observed a change in the surface morphology between porous and non-porous copolymers. Porous copolymers showed up to 37% weight loss in six-week soil burial tests, confirming biodegradability, and exhibited stronger antimicrobial activity against <i>Staphylococcus aureus</i> and <i>Escherichia coli</i> compared to their non-porous counterparts. Batch adsorption for RB5 removal showed that S-L-N achieved the highest removal efficiency of 64% under optimized conditions (pH 7.5, 35 °C, 50 mg dosage), while non-porous S-L removed only 8%, demonstrating that porosity unlocks the adsorption potential of chemically active but physically inaccessible sulfur sites. Kinetic modeling confirmed that all four copolymers follow the pseudo-second-order (PSO) model (<i>R</i><sup>2</sup> = 0.9999-1.000), with rate constants k2 following the order S-S (0.1689) > S-L-N (0.1261) > S-S-N (0.1166) > S-L (0.0504 g·mg<sup>-1</sup>·min<sup>-1</sup>), confirming chemisorption as the dominant rate-controlling mechanism across all systems. Equilibrium data were best described by the Freundlich model (<i>R</i><sup>2</sup> = 0.973-0.996) for all copolymers.

Analytical results revealed significant spatiotemporal variations in microplastic abundance across the studied regions: hospital and restaurant regions (HRR) exhibited concentrations ranging from 5.73 ± 0.81 to 13.57 ± 7.95 items/L, play and entertainment regions (PER) showed higher levels (8.2 ± 1.06-19.73 ± 3.73 items/L), while primitive arboretum region lake (PAR) maintained comparatively lower values (2.93 ± 1.3-11.4 ± 1.8 items/L). Morphologically, the microplastics were mainly fibers, some were fragments and films, and a small amount were pellets. In terms of physical characteristics, blue was the dominant color, and the most frequent particle size was mainly 0-1 mm. Notably, microplastic concentrations displayed marked seasonal fluctuations across all sites, with levels in anthropogenic zones (HRR and PER) being 0.82-5.29 times higher than natural arboretum environments (PAR). These findings underscore the critical role of artificial lakes as potential microplastic accumulation hotspots, highlighting the necessity for differentiated management strategies between artificial and natural lacustrine systems.</p>","PeriodicalId":15671,"journal":{"name":"Journal of Environmental Science and Health Part A-toxic\\/hazardous Substances & Environmental Engineering","volume":" ","pages":"475-481"},"PeriodicalIF":2.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147816211","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}
