Preferential adsorption of Cd, Cs and Zn onto virgin polyethylene microplastic versus sediment particles

Sorption of chemical contaminants on degradable and non-degradable microplastics: Recent progress and research trends

“…This line of research has come a long way, focusing on chemical pollutants from a wide range of sources. We have divided the recent progress of the interaction of chemical pollutants and microplastics based on the type of chemical, source or commercial use: Flame retardants (Chen et al, 2019;Xu et al, 2018a;Seidensticker et al, 2018), metals (Besson et al, 2020;Guo et al, 2020aGuo et al, , 2020bWang et al, 2020aWang et al, , 2020bWang et al, 2021;Zhou et al, 2020b;Zon et al, 2020;Zou et al, 2020), PAHs (Li et al, 2020;Lin et al, 2019;Wang et al, 2019;Zhao et al, 2020), PBDEs (Wu et al, 2020a(Wu et al, , 2020bXu et al, 2019), PCBs (Lin et al, 2019;Zhan et al, 2016), PHCs (Qiu et al, 2019;Zhang et al, 2019), Phthalate esters (Liu et al, 2019a(Liu et al, , 2019b(Liu et al, , 2019c, personal care products (Dong et al, 2019;Ho and Leung, 2019;Li et al, 2019;Wu et al, 2020aWu et al, , 2020bZhang et al, 2018aZhang et al, , 2018b, pesticides (Gong et al, 2019;Šunta et al, 2020;Tubić et al, 2019), pharmaceuticals (Guo et al, 2018(Guo et al, , 2019a(Guo et al, , 2019b…”

COVID-19 discarded disposable gloves as a source and a vector of pollutants in the environment

“…Gradual release of contaminants locally influences wildlife by disturbing their development and leads to various disorders. Additionally, plastic materials are characterized by adsorptive properties by which different inorganic (heavy metals) ( Besson et al, 2020 , Zhang et al, 2020a ) and organic contaminants (e.g. polycyclic aromatic hydrocarbons (PAHs) ( Lei et al, 2020 , Rochman et al, 2013 ), pharmaceuticals ( Elizalde-Velázquez et al, 2020 , Wu et al, 2016 ) and personal care products ( Dong et al, 2019 ) may be adsorbed, accumulated and transported ( Fig.…”

“…The lack of knowledge concerning adsorption capacity of natural and synthetic rubbers makes it impossible to assess the risk of pollutants accumulation by rubber gloves. Up to now, the adsorption capacity to heavy metals (Pb, Cd, Cr, Cs, Cu, Zn) and organic pollutants (polycyclic aromatic hydrocarbons, pharmaceuticals, pesticides and others) on PVC and PE (which are used for vinyl and foil gloves production, respectively) were investigated ( Besson et al, 2020 , Chen et al, 2019a , Dong et al, 2019 , Li et al, 2018 , Razanajatovo et al, 2018 , Wang et al, 2020e , Wang et al, 2021 , Yu et al, 2020 , Zhang et al, 2020b , Zon et al, 2018 , Zon et al, 2020 ). Up to now, most of the experiments related to adsorption of heavy metals by plastics applied pristine or aged particles and no research has been done regarding gloves.…”

“…It has been shown ( Besson et al, 2020 ) that PE can adsorb heavy metals, such as Cd, Cs and Zn. Adsorption capacity of pristine microplastics (MPs) of PE (32-75 μm PE beads) was lower than natural sediment particles (35-91 μm).…”

“…After 72 h of exposure, pristine PE MPs adsorbed less than 0.8% of Zn, Cs and Cd added to the solution, while for sediment particles the values ranged from 2.5 to 71.0%. It may suggest that the pristine PE MPs not efficiently adsorb and transport Zn, Cs and Cd in marine environment ( Besson et al, 2020 ). LDPE microbeads (with size 200-300 µm) were used as plastic models to evaluate the adsorption kinetics of Cd ( Zon et al, 2020 ).…”
