Influence of microplastics occurrence on the adsorption of 17β-estradiol in soil

Transport and transformation of microplastics and nanoplastics in the soil environment: A critical review

“…The introduction of oxygencontaining functional groups reduces the hydrophobicity (Ng et al, 2018), changing the vertical transport and mobility of MPs/NPs in the soil (Horton et al, 2017;Ng et al, 2018). After irradiation by four 15 W UV lamps (γ max = 254 nm) for 96 hr, the photo-aged PS, PVC and PE MPs (200 ± 10 μm) changed from white to light yellow/yellow MPs (Hu et al, 2020). Some cracks appeared on the surface of MPs/ NPs after ageing treatment, resulting in the increase of the roughness and specific surface area (SSA) (Hu et al, 2020).…”

“…Persistent organic pollutants such as polycyclic aromatic hydrocarbons (PAHs) and organochlorine pesticides (OCPs) are hydrophobic organic compounds, which can be absorbed by MPs/NPs through hydrophobic force (Wang & Wang, 2018). Studies have shown that the adsorption process of 17β‐oestradiol (E2) on MPs/NPs in soil follows the pseudo‐second‐order kinetics ( R 2 = 0.85–0.99), which is a chemical adsorption process (Hu et al., 2020). The adsorption mechanism is attributed to the interaction of π‐π interaction and hydrogen bonding (Jiang et al., 2016; Tong et al., 2019).…”

In addition, the aged PS produced –CH 2 bending vibration at 1,451 cm −1 , indicating that the photoaging caused the rupture of benzene ring (Hu et al., 2020).…”
