MeSH headings : Adsorption; Cities; Diffusion; Environmental Pollutants / chemistry; Hydrophobic and Hydrophilic Interactions; Motion; Organic Chemicals / chemistry; Plastics / chemistry; Refuse Disposal; Toluene / chemistry
TL;DR:
Plastics in landfills are potential sinks of hydrophobic organic contaminants (HOCs) because of their higher affinity for HOCs compared to lignocellulosic materials and the slow desorption of H OCs from glassy plastics.
