MeSH headings : Adsorption; Biological Availability; Fatty Acids / chemistry; Hazardous Waste; Plastics; Refuse Disposal; Solubility; Solvents / chemistry; Toluene / chemistry; Volatilization; Xylenes / chemistry
TL;DR: Results of this study showed that sorbent organic matter affinity for hydrophobic organic contaminants (HOCs) increases with increasing extent of MSW decomposition because of the recalcitrance of plastics and the preferential degradation of polar biopolymers. (via Semantic Scholar)
