Fourier transform infrared (FTIR) is a spectroscopy technique widely used to identify organic materials. It has recently gained popularity in microplastic (MP) pollution research determine the chemical composition of unknown plastic fragments. However, it could also be evaluate degree ageing MPs collected from environment. In this context, principal aim our been qualitatively natural weathering environmental an Italian freshwater body (the Ofanto River) using ATR-FTIR technology. Furthermore, we compared particles weathered artificial under controlled light and temperature conditions unaltered pristine materials assess results. FTIR spectra were acquired Nicolet Summit (ThermoFisher Scientific) equipped with Everest ATR diamond Crystal plate DTGS KBr detector (wavenumber range 4000-500 cm-1, 32 scans per spectrum, spectral resolution 4 cm-1). The was assessed three different indexes known related changes MPs: Carbonyl Index (CI), Hydroxyl (HI), Carbon-Oxygen (COI). overall results showed that regions reflecting (hydroxyl groups, peaks 3100 3700 alkenes or carbon double bonds, 1600 1680 carbonyl 1690 1810 cm-1) appeared significantly modified calculated for polymers degraded photo thermo displayed general tendency increase time contact irradiation time. Particular enhancements CI PS fragment PE pellet, HI fragments COI observed. Otherwise, following incubation same at constant 45 °C did not further affect particles. Moreover, new unique observed particles, almost all fingerprint region (1500-500 Differences CI, HI, evidenced among morphological MP shapes. On one hand, pellets values ranging 0.05 0.26 mean value 0.17 ± 0.10. Most samples (57%) presented between 0.16 0.30. other slicer modifications lower than (0.05 0.05). This index helps degradation by UV light, increasing enhancing residence Conversely, greater (5.90 2.57) (1.04 0.48) pellets, as well lines, which maximum (11.51). attributed bond vibrations hydroxyl, carboxyl, phenol groups. contrast, frequently C_O bonds found carbohydrates, alkanes, secondary alcohols, ketones. conclusion, characteristics aged ones. interpretation main emphasizes need conduct ecotoxicological experimental studies naturally due unicity their properties, are more helpful understanding effects.

The micro-, submicron-, and nanoplastic hunt: A review of detection methods for plastic particles

Chemosphere, Год журнала: 2022, Номер 293, С. 133514 - 133514

Опубликована: Янв. 8, 2022

Plastic particle pollution has been shown to be almost completely ubiquitous within our surrounding environment. This ubiquity in combination with a variety of unique properties (e.g. density, hydrophobicity, surface functionalization, shape and size, transition temperatures, mechanical properties) the ever-increasing levels plastic production use begun garner heightened interest scientific community. However, as result these properties, particles are often reported challenging study complex (i.e. real) environments. Therefore, this review aims summarize research generated on multiple facets micro- nanoplastics field; ranging from size definitions detection characterization techniques generating reference particles; order provide more complete understanding current strategies for analysis particles. information is then used generalized recommendations researchers consider they attempt plastics analytically environments; including method validation using obtained via presented creation methods, encouraging efforts towards standardization through reporting all technical details utilized study, providing analytical pathway depending upon exact knowledge desired samples being studied.
