Bioretention systems are designed for quality treatment of stormwater. Particulate contaminants commonly treated efficiently and accumulate mainly in the surface layer bioretention filter material. However, concerns exist that microplastic particles may not show equal accumulation behavior as other sediment particles. So far only two field laboratory studies available on fate microplastics few relatively newly built systems. Therefore, this study investigated abundance distribution nine 7-12 years old stormwater It was found generally Microplastic median particle concentrations decreased significantly from (0-5 cm) material to 10-15 cm depth 448 136 particles/100 g, respectively. The distance inlet did affect particles, suggesting modest spatial variability older Further, polymer composition shown PP, EVA, PS EPDM rubber most abundant types Also, it large percentages black (median percentage particles: 39%) which were 28 33 samples. This underlines importance including stormwater, has been overlooked previous studies.

Assessment of Tire-Additive Transformation Product 6PPD-Quinone in Urban-Impacted Watersheds

ACS ES&T Water, Год журнала: 2024, Номер 4(4), С. 1422 - 1432

Urban stormwater is a conduit for pollutants such as nutrients and tire-wear compounds through streams to the Great Lakes receiving waters. The transformation product of tire antiozonant 6PPD, 6PPD-quinone (6PPD-Q), implicated in causing fish mortality. entering Lake Ontario waters adjacent urban centers Toronto Hamilton, Ontario, were assessed 6PPD-Q its potential impact aquatic life. Sampling occurred during fall spring dry- wet-weather flows 2021–2022, overlapping with spawning times. Concentrations elevated (maximum 82 ng/L) greatest degree urbanization road density but much lower (2.4–4.5 nearshore waters, suggesting rapid dilution. Precipitation, within watersheds, chloride (from salts), total phosphorus correlated concentrations, that parameters may provide means identify prioritize key stream habitats further assessment. A screening level hazard assessment using application factors 10–1000 available toxicity end points (rainbow trout, brook coho salmon) showed concentrations pose risk region. We recommend quality control measures be their effectiveness reducing concentrations.

Domestic wastewater is one of the main sources microplastic (MP) contamination in aquatic environment; however, most treatment plants (WWTPs) have not been designed for removal MPs. In this study, release rate MPs treated water from a WWTP into river was estimated to be approximately 105 × 103 pcs/capita/day. Thus, bioretention systems are as tertiary reduce number resources. The objective study evaluate performance using umbrella plant (Cyperus alternifolius L.) and common reed (Phragmites australis) MP removal. After 17 weeks, were found system. root system substrate influence retention process greater extent through physical filtration, ratio, roots, biofilms on roots. Additionally, played an important role low-density accumulation roots hairs inevitably impacts plants. results showed that at 3:2:9 ratio (gravel: sand: soil) had highest relative height growth (RHGR) (1.8 mm cm−1 week−1). These show HSFs–3 able MPs, with average efficiency 62.89 % 95.45 sizes >1000 µm, 89.21 500–1000 44.16 <500 µm. microbeads 95.24 %. Our suggest Horizontal Subsurface Flow effective removing wastewater.

Removal and fate of microplastics in permeable pavements: An experimental layer-by-layer analysis

The Science of The Total Environment, Год журнала: 2024, Номер 929, С. 172627 - 172627

The increasing prevalence of microplastics (MP) in urban environments has raised concerns over their negative effects on ecosystems and human health. Stormwater runoff, road dust sediment, act as major vectors these pollutants into natural water bodies. Sustainable drainage systems, such permeable pavements, are considered potential tools to retain particulate pollutants. This research evaluates at laboratory scale the efficiency interlocking concrete pavements (PICP) porous (PCP) for controlling microplastics, including tire wear particles (TWP) which constitute a large fraction environments, simulating surface pollution accumulation Mediterranean rainfall conditions. Microplastic levels sediments stormwater runoff inputs were 4762 ± 974 MP/kg (dry weight) 23.90 17.40 MP/L. In infiltrated effluents, microplastic ranged from 2.20 0.61 5.17 1.05 MP/L; while particle between 0.28 3.30 0.89 TWP/L. Distribution within layers PICP PCP also studied quantified. Microplastics tend accumulate geotextile layers, allowing retention efficiencies 89 % 99.6 %. Small sized (< 0.1 mm) fragment shaped most common effluent samples. results indicate that powerful tool capture particles, especially by layers. study aims shed light complex mobilisation mechanisms providing valuable insights addressing growing environmental concern areas.
