Biodegradable plastic mulches (BDMs) can offer an eco-sustainable alternative to conventional polyethene (PE) mulch films in agriculture. While PE must be removed after use, BDMs are tilled into the soil, where they expected biodegrade. However, their long-term impacts on soil ecosystem (functions, processes, and microbial communities) remain unclear. This review critically analyses evidence about potential of as a possible eco-friendly traditional mulches. It updates available literature fate agriculture ecosystems, pinpointing crucial aspects that deserve further investigation. The combined findings indicated BDM incorporation could stimulate activity may ultimately affect organic matter dynamics. using should linked risks incomplete biodegradation by releasing residual bio-microplastics, bio-nanoparticles additives. We here highlighted gaps knowledge (i.e. impact ecology risk toxicity) need for studies natural environmental conditions well field experiments evaluate actual health agroecosystem sustainability. Moreover, there still needs more clarity standards covering under which biodegradable biodegrade ensure safe end-of-life.

Microplastics are a growing concern due to their potential negative environmental and human health impacts. This study investigated the physiochemical changes in polyethylene terephthalate (PET) microplastics upon aging air, seawater, freshwater through exposure Xenon light (artificial aging) sun (natural aging). We used SEM examine surface morphology of natural aged PET found that particles exhibited mechanical grinding, irregular wrinkles, cracks, small subset mesopores. FTIR analysis revealed were degraded an oxidation process, resulting appearance carboxyl hydroxyl groups. BET showed freshwater-aged had highest specific area (SBET) value. also studied sorption behavior oxybenzone, UV filter compound, onto microplastic particles. Our results indicated followed pseudo-second-order model, with hydrophobic interactions hydrogen bonding formation as main mechanisms. The equilibrium adsorption values for increased from 6.62 9.10 mg/g freshwater, respectively, compared 6.44 virgin microplastics. isotherm experiments Langmuir model could represent mechanism materials, while air- seawater-aged more accurately described using Freundlich model. initial concentrations oxybenzone background solutions increasing trend concentrations, pH different effects on capacity depending age solution pH. suggest exhibit enhanced conditions, uneven distribution active groups each crack formation. Further research is needed explore desorption resources.
