The interaction between microplastics (MPs) and pollutants is crucial for assessing the environmental risk of MPs. It necessary to pay attention adsorption/desorption behavior antibiotics on MPs due their potential role in antibiotic resistance. When MPs-loaded are ingested by organisms, they enter gastrointestinal tract undergo desorption, leading corresponding toxic effects. Existing literature primarily focuses adsorption behavior, while there a lack systematic generalizations desorption or combined effects organisms. Therefore, this article provides review mechanisms, biological tract. Desorption suggests that characteristics (aging hydrophobicity) components fluid (digestive enzyme species pH) can also have effect desorption. Moreover, summarizes induced MPs-antibiotics, demonstrating either enhance reduce plants, microorganisms, aquatic animals. Since methodological uniformity relevance natural environment main shortcomings existing literature, future research should focus actual water given region studying at gene, protein, metabolic levels. This direction expected provide valuable references insights evaluating antibiotics.

Microplastic–pesticide interactions influence pesticide performance, soil health, and environmental safety. This review aims to comprehensively present the effects of microplastic–pesticide on bioavailability, persistence, toxicity, along with their agricultural implications pest control. It reviews more than 90 related articles from established scholarly databases. Most studies indicate that bioavailability decreases in presence microplastics due adsorption, which is frequently influenced by hydrophobicity (log Kow) pesticides surface area type microplastics. Higher log Kow results higher adsorption lower bioavailability. Aged have areas for thus reducing effectiveness systematic contact pesticides. Lower leads less former plants control infestation latter pests kill them directly. also increases persistence pesticides, as indicated extended degradation half-lives. However, some demonstrate biodegradable microplastics, especially aged ones, effect because they release when break down. Few how alter toxicity target organisms are available, but available ones point potentially crops beneficial organisms. Overall, highlights a significant negative may prompt application achieve desired level crop protection, bears cost consequences.

ABSTRACT This study examined the adsorption capacities of biochars derived from kenaf (KF‐BCs) for removal heavy metals such as Cu(II) and Pb(II). The thermal decomposition temperature (300–750°C) significantly influenced morphology composition KF‐BCs, enhancing their surface area, pore structure, alkalinity. Among them, pyrolyzed at 750°C (KF‐750) was most effective in removing Pb(II), validated by kinetic, equilibrium, isotherm model analyses. Adsorption kinetics revealed that equilibrium attained after 24 h, with chemisorption governing process rate. Equilibrium conformed to Langmuir Freundlich models respectively. KF‐750 exhibited midrange Pb(II) (23.47 ± 0.3 mg/g 50.07 0.9 mg/g, respectively), compared literature. thermodynamic assessment an endothermic positive ∆ H 0 , indicating higher temperatures favor metal adsorption. At low pH, decreased due electrostatic repulsion, particularly affecting Cu(II). More than 99.8% were removed a 5.00 g/L dose. cation effect order on Ca 2+ > Mg Na + K . Overall, demonstrates promising potential adsorbent efficient aqueous solutions, presenting viable option environmental remediation.

Abstract The contamination of water resources by tannery wastewater containing Cr(III) presents significant public health risks due to its carcinogenic nature. Addressing this critical issue, the purpose research is develop and evaluate novel alkylammonium‐modified bentonite adsorbents for efficient removal from wastewater. Batch experiments were conducted investigate effects Cr concentration (0.02–0.2 mg/L), adsorbent dose (0.25–2.5 g/L), pH (2.0–8.0), temperature (293–313 K) on adsorption performance. alkylammonium modifications enhanced surface area ion‐exchange capacity 40% 50%, respectively. Optimal conditions identified as 313 K, 1 g/L dosage, 2.0, 30 min reaction time, 150 rpm agitation speed. Langmuir isotherm model ( R 2 = 0.998 trimethylammonium [TMB], 0.994 triethylammonium [TEB]) confirmed monolayer adsorption, while negative Gibbs free energy values demonstrated spontaneous nature process. Enthalpy changes (ΔH°) 21.1 kJ/mol (natural Navbahor [NNB]), 26.7 (TMB), 28.4 (TEB) indicated endothermic reactions. This work highlights novelty a cost‐effective scalable solution reducing in wastewater, providing promising pathway sustainable resource management.

Recent pesticide use is alarmingly high and unregulated in several parts of the world. Pesticide fate soil controlled by sorption processes which affect subsequent transport chemical reactivity environment, as well uptake plants. Sorption are dependent on composition properties, but these beginning to be affected global warming-linked factors leading depletion. Thus, it vital decipher soils' response, especially sub-Sahara (SS), depletion some inherent components presence pesticides. This was ascertained monitoring a model (atrazine) desorption whole SS (WS), same whose organic matter (OMR) iron oxides (IOR) were substantially depleted, studying atrazine from soils fast-growing vegetables. Organic enhanced equilibrium OMR. at lower ambient pH, higher initial concentration, temperature. Hysteresis low resulting desorption. Overall, ≥65 % observed; OMR (≥95 %) since SOM hysteresis. Though sub-Saharan rich oxides, played significantly role than this soil. result suggests potential for leach into aquifer sub-Saharan. Atrazine experiment waterleaf spinach showed that could detected after 63 d, its growth both vegetables with depleted (100 µg/kg) spiking. Spinach may accumulator waterleaf. It concluded grown atrazine-contaminated soils, SOM/iron oxide-depleted likely accumulate atrazine.
