ABSTRACT Stormwater is recognised as a vector for microplastics (MPs), including tyre wear particles (TWPs) from land-based sources to receiving waterbodies. Before reaching the waterbodies, stormwater may be treated. In this study, sediments six treatment facilities (five retention ponds and subsurface sedimentation tank) were analysed understand MP occurrence, concentrations, sizes, polymer types distribution between inlet outlet. The concentrations of MPs showed large variations within different with 1,440–72,209 items/kg (analysed by μFTIR) corresponding 120–2,950 μg/kg TWP <DL up 69,300 pyrolysis–GC–MS), significantly higher at compared Polypropylene (PP) was predominant type in terms number all samples. TWPs dominant mass most (nine) relatively low density PP polymers implies that might not sole factor influencing particle settlement behaviour. Small occurred more frequently than ones; around 70% detected samples 100 μm or smaller. summary, study highlights occurrence MPs, TWPs, demonstrates depending on sites locations facility.

Retention of microplastics (MPs) at the third largest wastewater treatment plant (WWTP) in Sweden was investigated. The is one most modern and advanced its kind, with rapid sand filter for tertiary combination mechanical, biological, chemical treatment. It achieved a significantly high efficiency, which brought MP concentration discharge on par concentrations measured marine waters same region. This novel data shows that properly designed WWTPs can reduce content sewage down to background levels receiving aquatic environment. Opposite current understanding retention by WWTPs, well-designed WWTP does not have be significant point source MP. MPs were quantified all major steps, including digester inlet outlet sludge. sized 10–500 µm analyzed focal plane array based micro-Fourier transform infrared (FPA-µFTIR) microscopy, hyperspectral imaging technique, while above 500 Attenuated Total Reflectance-Fourier (ATR-FTIR) spectroscopy. Mass estimated from images <500 microscope >500 µm. overall efficiency terms counts 99.98%, daily input 6.42 × 1010 output 1.04 107 particles. mass removal 99.99%. mechanical part treatment, pre-treatment, primary stages, reduced both approximately 71%. combined biological secondary settling, final polishing filtration removed nearly remaining 29%. became successively smaller as they passed different steps. received 1011 daily, it discharged 9.96 MPs, causing small but decrease counts, corresponding reduction 9.56%.

Urban runoff is an important conveyor of microplastics (MPs) and tyre wear particles (TWP) to receiving waters. However, knowledge contributions by surfaces within land use type/activities currently limited. To address this gap, samples were collected simultaneously during three rainfall events in October November 2020 at locations Luleå, Sweden, with different urban (parking lot, road roof). The occurrence MPs (by number estimated mass) TWP (mass) determined using μ-FTIR Pyr-GC/MS, respectively. found all sites events, large variations between sites. highest concentrations (number) followed parking lot roof runoff. mass did not follow the same pattern generally highlighting importance reporting data as both particle numbers derive a complete overview behaviour.
