The environmental fate of phthalate esters: A literature review
TL;DR: A comprehensive and critical review of the environmental fate of eighteen commercial phthalate esters with alkyl chains ranging from 1 to 13 carbons was performed by as discussed by the authors, which revealed that most published values exceed true water solubilities due to experimental difficulties associated with solubility determinations for these hydrophobic organic liquids.
