We are pleased to announce the publication of the following paper in
Sala, B., Giménez, J., de Stephanis, R., Barceló, D., & Eljarrat, E.
(2019). First determination of high levels of organophosphorus flame
retardants and plasticizers in dolphins from Southern European waters.
This study evaluates for the first time organophosphorus flame retardant
(OPFR) occurrence in the Alboran Sea delphinids (Spain). OPFRs were
detected in all the individuals with concentration levels up to 24.7 μg/g
lw. Twelve out of sixteen tested analytes were detected, being TBOEP which
presented the highest detection frequency, and IDPP which presented the
highest levels of concentration. OPFR distribution in different tissues
(blubber, brain, kidney, muscle and liver) was evaluated. The pattern
distribution showed the highest contribution for blubber (mean value of
68%) and the lowest contribution for liver (mean value of 2%). Seven OPFRs
were detected in brain samples showing their capacity to surpass the
blood-brain barrier and reach the brain. Moreover, high affinity for the
brain tissue was observed. This is extremely important due to the
neurotoxic effects of several compounds such as TCEP and TNBP. OPFR levels
were compared with previously published PBDE concentrations, and no
significant differences were observed. Taking into account the lower use
and lower bioaccumulation and biomagnification capacities of OPFRs, this
could indicate an additional OPFR source of pollution in addition to their
use as FRs.
