Results depicted that drought stress markedly disrupted morphological growth, biomass production and yield parameters of wheat exposed to varying levels of drought. However, application of different soil amendments and selenium spray, alone and in combination, positively minimized the injurious effects of drought stress on wheat. Among various treatments, the combined application of vermicompost in soil and selenium (Na₂SeO₃) foliar spray (T₅) showed more promising results at all levels of drought stress. Maximum increase in growth parameters including plant height (11.83 %), leaf area (19.14 %), and number of tillers (9.35 %) of wheat was found in combined treatment of vermicompost and Na₂SeO₃ (T₅). Likewise, total chlorophyll, carotenoids, soluble proteins also showed significant increment by applying vermicompost and Na₂SeO₃ together. Combined application of vermicompost and Na₂SeO₃ (T₅) also reduced malondialdehyde (MDA), hydrogen peroxide (H₂O₂) and superoxide anion (O₂¯) levels by 46.5–48.2 %, 49.1–58.9 % and 20–30 %, respectively, in wheat exposed to varying drought stress. Antioxidant enzyme activities i.e., superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) and ascorbate peroxidase (APX) were also increased in T₅ by 110.7–489 %, 54.5–152.7 %, 84.2–220.2 % and 26.01–534.2 %, respectively, in wheat plant under varying drought levels.

However, the implementation of photocatalyst, i.e. graphitic carbon nitride (gC₃N₄), to treat dye-laden wastewater has proven to be ineffective, primarily owing to its restricted absorption of visible-light, rapid charge recombination, low absorption capacity, and inactive degradation efficacy. To improve these obstacle, gC₃N₄ (gCN) was loaded on algal-biochar (BC) to enhance its optical properties and energy bandgap by synthesizing gCN@BC₃ and then integrated it with peroxydisulfate (PS) to improve the reaction kinetics for dye degradation_. The synthesized gCN@BC₃ photocatalyst demonstrated better optical-electronic properties including light absorbance in visible region, slow charge recombination, and reduced energy bandgap (∼2.62 eV), as they improved the dye (methylene blue) degradation kinetics (degradation rate (min^-1)) and overall process efficacy. Upon the integration of PS with gCN@BC₃ photocatalyst, the process efficacy and degradation kinetics were significantly improved up to 99.94 % and 0.041 min^-1 as compared to the control (96.82 % and 0.029 min^-1) system without PS. Photogenerated radicals, including superoxide, hydroxyl, and sulfate species, play a key role in the degradation of organic dyes by enhancing process efficacy and kinetics.

However, limited research studies addressed source apportionment, and carcinogenic - non-carcinogenic risks assessment of pollutants within the marble waste polluted ecosystem (MWPE). Therefore, positive matrix factorization (PMF), environmental and human health risk indices along with the Monte Carlo Simulation modeling and Structural Equation Modeling (SEM) procedures were applied to examine the health risks and role of vegetation abundance in mitigation of those risks. The PMF results comprehended four major sources of the heavy metals (HMs) pollution i.e., F1 (traffic), F2 (natural), F3 (dolomite marble) and F4 (calcite marble). Nickel (1.85 to 50.55 mg/kg), copper (3.51–91.68), cadmium (0.59–56.93 mg/kg), and zinc (0.7–148.55 mg/kg) exceeded from the recommended threshold levels given by World Health Organization (WHO). The MWPE exhibited a high degree of HMs (cadmium, chromium, iron, nickel, manganese and zinc) pollution based on the Degree of Contamination (8.43–78.61), Metal Pollution Index (&gt;1) and potential ecological risk index (1520.11). Human health risks based on hazard quotient and hazard index (&gt;1) indicated a high risk of individual HMs both in adults and children in the MWPE. Ni and Cd were the dominant HMs responsible for the carcinogenic as well as non-carcinogenic risk in adults and children followed by Cr&gt;Mn&gt;Cu&gt;Zn. Dermal exposure has been recorded as the major contribution pathway followed by inhalation and ingestion for health risks. SEM comprehends that with the increase in HMs (Cd, Cr, Cu, Fe, Mn, Ni, Zn) concentration, the associated environmental risk (PERI, MPI &amp; DC) also increases (β=0.97). While higher plant species abundance mitigates or reduces (β= -0.62) the environmental risks within the MWPE. It is concluded that the HMs released from marble mining and processing cause significant environmental and human health (carcinogenic and non-carcinogenic) risks, while plant species play an important role in the mitigation of these risks and toxicities. It is recommended to increase the vegetation cover by cultivating more plants especially the indicator species in the MWPE through afforestation and reforestation. Awareness programs about the health risks associated with HM exposure are necessary to educate people working in the marble industry or residing near marble processing units along, with protective pollution mitigation strategies.</div></div>","PeriodicalId":73763,"journal":{"name":"Journal of hazardous materials advances","volume":"18 ","pages":"Article 100689"},"PeriodicalIF":5.4,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143685185","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}

After that, a series of experiments were conducted in which various types of MOC-based composites were synthesized and analyzed. Reference MOC sample was prepared with silica sand as a filler and in the samples containing SRDF, silica sand was replaced by SRDF in the amount of 50, 100, and 150 wt%. The prepared samples' microstructure, chemical and phase composition, mechanical properties, structural parameters, and water resistance were analyzed. For these purposes, XRD, XRF, OM, SEM, EDS, AAS, ICP-OES, and standardized tests for micro- and macrostructural, mechanical, and hygric parameters were used. The obtained results showed the positive influence of the addition of SRDF on the water resistance of the MOC-based composites manifested in reduced water uptake and absorption and an increase in the softening coefficient after immersion in water. Therefore, using SRDF as the sole filler, especially in significant quantities, positively impacted water resistance, effectively addressing the principal deficiency inherent in MOC-based materials. Moreover, the hazardous HMs present in SRDF were effectively immobilized within the structure of the synthesized composites.
