Uptake and photoinduced degradation of phthalic acid esters (PAEs) in Ulva lactuca highlight its potential application in environmental bioremediation.

ABSTRACT: The bioaccumulation of phthalates was studied in fragments of Ulva lactuca exposed for a maximum of 31 days at different concentrations of a solution of six phthalic acid esters (PAEs). The algal matrix showed rapid uptake since the first sampling, which increased over the time of the experimental period, at the end of which seaweed's bioaccumulation potential was also evaluated. After the uptake, the algal matrix was subjected to UV irradiation in order to verify the removal of the phthalates. PAEs with higher octanol-water partition coefficients (logK_ow) and molecular weights were preferentially uptaken by U. lactuca in all the exposure experiments. It was observed that both accumulation (biota-sediment accumulation factor (log₁₀BSAF) ranging from 3.75 to 4.02) and
