Sorption of three common nonsteroidal anti-inflammatory drugs (NSAIDs) to microplastics

Sorption Behavior and Mechanisms of Organic Contaminants to Nano and Microplastics

“…Wang et al [31] reported that the sorption amount of FOSA on PE was higher than that of PFOS, and this could be attributed to the sulfonamide functional group on FOSA. Elizalde-Velázquez et al [64] also reported that the sorption of diclofenac sodium salt to MPs was enhanced due to the amino group in its structure.…”

Interaction of Environmental Pollutants with Microplastics: A Critical Review of Sorption Factors, Bioaccumulation and Ecotoxicological Effects

“…In this case, a decrease of the pH led to an increment of the sorption rate of this flame-retardant compound [97]. In agreement with these results, Elizalde-Velázquez et al exposed that the pattern of nonsteroidal anti-inflammatory drugs (NSAID) sorption on MPs exhibited a pronounced pH dependency due to the pH effect on the speciation of the compounds and the surface charge of the particle [98]. In contrast, Holmes et al exposed that higher sorption was observed as the pH of the solution increased for metals producing cationic species (e.g., Pb 2+ , Cd 2+ , Ni 2+ , Co 2+ ).…”

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

“…Increased use of DPGs have generated a significant amount of gloves waste in both landfills and random places. Plastics, poorly-degradable materials are not environmentally inert ( Elizalde-Velázquez et al, 2020 ). The components of DPGs such as heavy metals and organic chemicals may be easily released from gloves and may contaminate water and soil ( Garçon et al, 2017 , Hospital et al, 2007 , Kawamura et al, 2002 , Kawamura et al, 2000 , Reichel, 2012 , Sugiura et al, 2002 , Wakui et al, 2001 ).…”

“…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. 5 ).…”

“…The different anthropogenic organic contaminants, which are not constituents of plastics, are another group of substances, which may be adsorbed on plastics. The adsorption capacity of PE and PVC to PAHs ( Frias et al, 2010 , Hirai et al, 2011 , Karapanagioti et al, 2010 , Lei et al, 2020 , Rochman et al, 2013 ), polychlorinated biphenyls ( Camacho et al, 2019 , Frias et al, 2010 , Hirai et al, 2011 , Mizukawa et al, 2013 , Rochman et al, 2013 ), pharmaceuticals ( Elizalde-Velázquez et al, 2020 , Li et al, 2018 , Razanajatovo et al, 2018 , Wu et al, 2016 , Yu et al, 2020 ), organophosphate esters ( Chen et al, 2019a ), and others ( Dong et al, 2019 , Wang et al, 2020c , Wang et al, 2020e ) were investigated. PE has been characterized as a great sorbent of hydrophobic organic contaminants ( Karapanagioti et al, 2010 , Lei et al, 2020 ).…”
