Compilación de datos para revisión de efectos y bioacumulación de PFAS en plantas acuáticas

Abstract

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a group of chemicals that have been manufactured globally since the 1950s but are considered contaminants of emerging concern. Due to their extreme persistence and high bioaccumulation potential, they are known as "forever chemicals". Their ubiquitous occurrence in the environment has led to study the toxicity in biota.

The aim of this chapter was to compile and review the available information about phytotoxicity (e.g. NOEC, IC50, and morphological, physiological, molecular and biochemical biomarkers) of individual PFAS and their mixtures in aquatic macrophytes of different growth status. Free-floating, submerged and wetland macrophytes, such as, Eichhornia crassipes and Lemna spp., Vallisneria natans and Hydrilla verticillate, Cyperus alternifolius and Phragmites communis, respectively, among others were analyzed. Data on uptake, remotion, tissue bioaccumulation, metabolism, biofilm-related effects, and phytotoxicity of mixtures of PFAS with other contaminants were discussed.
