Large increases in concentrations were observed for all compounds between 1980 and 2014, especially for BDE-209 (representative usage of Deca-BDE commercial mixture), which was found in surficial sediment at an average concentration of 42ng/g dry wt (21-65ng/g dry wt).

PBDE concentrations in surficial sediments were relatively high when compared with those presented in the available literature.
