Abstract Microplastic fibers (MPF) are the largest fraction of microplastics in environment by mass. The endpoints these contaminants' movement is generally known at large‐scale (i.e., their origins and where they end up), but mechanics how get to those sinks remains poorly understood. objective this work was improve understanding mechanisms driving MPF migration through terrestrial systems directly imaging motion idealized representations porous media. Monofilament line with 0.3 mm diameter passed a bench‐scale, pseudo‐2d flow cell capture trajectories MPFs three different lengths passive micro‐bead tracers were also captured. Video processing automated image analysis converted video experiments into database trajectories, allowing comparison experimental data various numerical models. Simple advection‐dispersion models adequate for modeling tracer did not provide good description transport. A physics‐based, distributed model able generate realistic domain, speeds initial simulation too fast, despite working well tracer. Adding delay (waiting time) process resulted travel times. specifics could be deduced from experiments, its overall impact on transport provides mechanistic insights. These direct observation moving media show that likely have strong interactions surroundings.

Microplastics (plastic particles < 5 mm) are ubiquitous pollutants that have the ability to carry microbiota, including pathogens. Microbial adhesion is usually a sign of pathogenicity; thus, we investigated adherent microbiota found on 4 mm nylon strips, which were ingested and excreted by wild fish specimens. Retention times recorded polymer analysis samples was performed, showed no signs degradation, nor did their controls, represented strips submerged in same water tanks. Both controls presented pathogens large quantities.

Microplastics are an emerging class of recalcitrant organic pollutants that general scientific and public interest nowadays. It would be ideal to remove microplastics from the environment through biodegradation, as biodegradation is a highly ecological economically acceptable approach. Unfortunately, efficiency conventional plastic polymers low. The application suitable pretreatment could increase biodegradation. In this study, applicability UV-C/H2O2 UV-C/S2O82− advanced oxidation processes pretreatments for polystyrene poly(vinyl chloride) by yeast Candida parapsilosis was investigated. For investigated range (pH 4–10, peroxide concentration up 20 mM treatment duration 90 min), process proved more effective in degrading microplastics, while efficient at microplastics. Samples pretreated under optimal conditions (90 min time pH 5.7 H2O2 20.0 samples; 8.6 S2O82− 11.1 samples) were subjected parapsilosis. included agitation speed 156 rpm initial experiments with samples, 136 4.9 used experiments. value optical density suspension 1.0 both cases. showed positive effect on number cells surface

With the increasing amounts of microplastic (MP) deposited in soil from various agricultural activities, crop plants can become an important source MP food products. The last three years studies gave enough evidence showing that plastic form nanoparticles (<100 nm) be taken up by root system and transferred to aboveground plant parts. Furthermore, presence affects growth disturbing metabolic processes plants, thus reducing yields quality. Some adverse effects on have been already described meta-analysis; however, this review provides a comprehensive overview latest findings about possible risks related wide occurrence production safety, including topics changes pesticides behavior pathogen spreading under possibly threaten human health.
