Results and discussion
Applicant's summary and conclusion
- Executive summary:
Loggerhead turtles (Caretta caretta) voluntarily ingest floating plastic debris and hence are chronically exposed to plastic additives, but very little is known about the levels of these compounds in their tissues. This work studied the presence of organophosphate esters (OPEs) on sea turtles collected from two different areas in the western Mediterranean, some of their prey and some floating plastic debris.
Currently, there is not enough information to assess whether the OPE concentration levels detected in urtles may represent a risk for them. There is insufficient knowledge related to OPEs toxicity, and there are no data regarding potential effects on turtles. Samples corresponding to the main turtle prey (jellyfish, squid and sardine), as well as different types of marine plastic debris were analysed.
Tributylphosphate (TNBP) was present in plastic debris (mean: 1.76 ng/g), turtle muscle (catalan coastline mean: 0.23 ng/g; balearic islands mean: 0.15 ng/g) and prey (mean: 0.83 ng/g) and for that reason turtles might acquire TNBP from plastic debris, diet or both. TNBP has a log Kow value lower than 4.5 as well as a bioconcentration factors (BCFs) below 2000, and hence a lack of bioaccumulative properties (EU REACH) and is thus more likely to be derived from plastic debris.
