Webwhere hydrophobic substances, in this case POPs and microplastics, tend to come together in an aqueous environment. This is demonstrated by the linear isotherm between POPs and microplastics in a few studies [13-16]. For polar POPs, their interactions with microplastics could be partially affected electrostatic force. WebMay 31, 2024 · Microplastics are then a vector of numerous chemicals to the aquatic environment. From all the substances, persistent organic pollutants (POPs) are of particular concern because of their long-term durability and their harmful properties for most of the living organisms. POPs are regulated since 2001 under the Stockholm Convention.
