Abstract:

Plastic debris has become an environmental problem during
recent years. Among the plastic debris, microplastics (<5 mm; MPLs)
imply an extra problem due to their capacity to enter into the fauna
through ingestion. In this work, we study the capacity of three MPLs,
that include high-density polyethylene (HDPE), polystyrene (PS) and
polystyrene carboxylate (PS-COOH), to sorb 18 perfluoroalkyl substances
(PFASs; including carboxylic acids, sulphonates and one sulphonamide)
from the surrounding waters (freshwater and seawater). Conclusions drawn
from the results are that perfluoro sulphonates and sulphonamides have
more tendency to be sorbed onto MPLs. In addition, PS and PS-COOH have
more affinity for PFASs than HDPE. Finally, the increment of
conductivity and pH of the water decreases the exposure time that is
necessary to reach equilibrium. However, the presence of salts decreases
the tendency of PFASs to be sorbed onto plastic surfaces. These results
highlight the problem associated with the presence of MPLs in inland and
marine waters since toxic compounds can be sorbed onto surrounding
plastics that could be ingested by aquatic fauna.
