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.

Comparison of reference libraries for the detection of tire-derived microplastics (TMPs)

ABSTRACT Introducing microplastics (MPs) into the marine environment is a global problem. Tire-derived (TMPs) are estimated to account for 60% of all secondary MPs dispersed in aquatic environments. To effectively detect TMPs environmental samples using micro-Fourier transform infrared (μFTIR) spectroscopy, high-quality reference library essential. However, use conventional diamond crystals FTIR presents challenges detection materials containing carbon black, such as rubber and tires. In addition, there discrepancy between spectra from standard libraries samples, which makes difficult. order overcome these problems by μFTIR, we developed four improve detection, ‘The 26 tire wear library’ was found be best among four. Furthermore, comparison new revealed following requirements TMP detection: (i) must acquired under same setup used material observation including prism material, (ii) tires, not rubber, materials, (iii) prepared replicate actual generation conditions on roads.
