Microplastics (MPs) pose significant environmental pollution problems owing to their diverse properties such as various shapes, sizes, compositions, surface features, and levels of degradation. Moreover, interactions with toxic chemicals aging processes add complexity research. This study investigated the adsorption triphenyl phosphate (TPhP) in soil-only, MP-only, soil-MP simulated environments under different conditions. The experiment involved three phases: initial exposure a pH 5.5 fluorescent light, subsequent introduction ultraviolet (UV) radiation, adjustment 4.0 7.0, while maintaining UV exposure, each lasting 7 days. found that factors affected TPhP sorption capacity, higher observed radiation acidic In contrast, MP-only systems showed no clear trend for adsorption, suggesting kinetic limitations. When MPs were added soil, dynamics altered, varying capacities MP polymers ATR-FTIR spectroscopy, micro-Raman water contact angle measurements suggested potential photooxidation changes hydrophobicity subjected provides valuable insights into interplay between soil properties, characteristics, determining environments.

Abstract Microplastics are emerging contaminants that undergo progressive aging under environmental conditions such as sunlight irradiation, mechanical forces, temperature variations, and the presence of biological organisms. Since modifies microplastic properties, their own toxicity trapped pollutants, advanced methods to analyze microplastics required. Here we review with focus on process, qualitative identification, quantitative characterization, chemometrics. Qualitative identification is done by techniques, thermal e.g., degradation gas chromatography–mass spectrometry, spectral infrared, Raman, fluorescent, laser techniques. Quantitative characterization microscopy mass spectrometry. Microplastic results in a series surface physical changes, biofilm formation, chemical oxidation, alternation, deterioration. Changes properties allow differentiate aged microplastics. Infrared Raman spectroscopy rapid sensitive for complex samples. Combining two techniques preferable accurate detection categorization.

Microplastics (MPs) pose a global concern due to their ubiquitous distribution. Once in the environment, they are subject aging, which changes chemical-physical properties and ability interact with organic pollutants, such as pesticides. Therefore, this study investigated interaction of hydrophobic herbicide terbuthylazine (TBA), is widely used agriculture, artificially aged polyethylene (PE) MP (PE-MP) understand how aging affects its sorption. PE was by an accelerated weathering process including UV irradiation, hydrogen peroxide, ultrasonic treatment, particles were characterized comparison pristine particles. Sorption kinetics performed for materials, while further sorption studies PE-MP included determining environmental factors pH, temperature, TBA concentration. found be significantly lower on compared because led formation oxygen-containing functional groups, resulting reduction hydrophobicity negatively charged sites oxidized surfaces. For PE-MP, best described pseudo-second-order model, it intra-particle diffusion result crack pore formation. followed decreasing trend increasing became less favorable at higher temperatures. The isotherm data revealed complex altered, heterogeneous surfaces involving interactions, bonding, π-π Sips adsorption model. Desorption low, confirming strong interaction. However, thermodynamic results imply that increased temperatures, those from climate change, could promote re-release into environment. Time-of-flight secondary ion mass spectrometry (ToF-SIMS) confirmed onto PE.

Since the onset of COVID-19 pandemic, there has been an increase in use disposable plastics and disinfectants. This study systematically investigated adsorption behavior mechanisms benzalkonium chlorides (BACs), commonly used disinfectants, on polypropylene (PP) polyethylene terephthalate (PET) microplastics (MPs), considering various factors, such as characteristics MPs, alkyl chain length BACs, environmental conditions. Our results demonstrated a higher capacity for PP-MPs with relatively hydrophobic properties compared to PET-MPs, where longer chains BACs (i.e., octanol-water partition coefficients, Kow) significantly enhanced through interactions. The inverse relationship between particle size MPs was evident. While changes pH minimally affected PP-MPs, PET-MPs increased rising pH, highlighting influence electrostatic Moreover, MP aging UV/H2O2 amplified BAC due surface oxidation fragmentation, whereas remained unaltered, resulting unchanged capacities. Spectroscopy studies density functional theory (DFT) calculations confirmed interactions primary mechanisms. These findings improve our understanding environment, providing insights risk assessments related combined pollution.

Abstract Although microplastics (MPs) in solid organic waste have been intensively studied, the presence of MPs fertilizer and their potential as new emerging pollution to environment because use agriculture has not explained completely. Therefore, identification quantification commercially available compost is important. This study aimed estimate quantity commercial composts. The characteristics (shape, color, size, type polymers) were identified. found that samples found, reaching up 160 particles/200 g with various colors (blue, black, red, yellow, white). identified had sizes (0.1–1 mm) shapes (81.8% fragment, 16.2% fiber, 2% filament). findings this are very important significant inform community policymakers regarding compost, hence, intensive must be controlled careful.

Microplastic (MP) accumulation in the environment is accelerating rapidly, which has led to their effects on both ecosystem and human life garnering much attention. This study first examine degradation of high-density polyethylene (HDPE) MPs via photoelectrocatalysis (PEC) using a TiO2-modified boron-doped diamond (BDD/TiO2) photoanode. was divided into three stages: (i) preparation photoanode through electrophoretic deposition synthetic TiO2 nanoparticles BDD electrode; (ii) characterization modified electrochemical, structural, optical techniques; (iii) HDPE by electrochemical oxidation bare electrodes under dark UV light conditions. The results indicate that PEC technique degraded 89.91 ± 0.08% 10-h reaction more efficient at lower current density (6.89 mA cm−1) with BDD/TiO2 compared BDD.
