Dear All,

On behalf of the team, I am pleased to share our recent publication in Marine Pollution Bulletin - Microplastics, bisphenols, phthalates and pesticides in odontocete species in the Macaronesian Region (Eastern North Atlantic).

Abstract:
The gastrointestinal contents of twelve individuals from six odontocete species that stranded between 2018 and 2019 in the Macaronesian Region (Eastern North Atlantic) were examined for the presence of marine debris. In addition, concentrations of eleven organic persistent contaminants<https://www.sciencedirect.com/topics/earth-and-planetary-sciences/persistent-organic-contaminant> (nonylphenols, bisphenols<https://www.sciencedirect.com/topics/earth-and-planetary-sciences/bisphenols>, phthalates<https://www.sciencedirect.com/topics/earth-and-planetary-sciences/phthalates> and pesticides) were analysed in muscle samples by liquid chromatography<https://www.sciencedirect.com/topics/earth-and-planetary-sciences/liquid-chromatography>. No particles larger than 5 mm were found, except for two plastic labels that were found on the same dolphin. On the contrary, all animals contained microplastics of diverse sizes, most of them being fibres (98.06%, n = 708). The predominant detected pollutants were bisphenols (4–984 ng/g) and DEHP (102–1533 ng/g). Also, except for two individuals, all animals had pesticide levels in their tissues. This work has allowed the establishment of a protocol for the study of microplastic ingestion in cetaceans, and tests the potential of microRaman to improve the understanding of microplastic alteration processes.

The paper is open-access and available for free download here: https://www.sciencedirect.com/science/article/pii/S0025326X21011395?via%3Dihub

Best wishes,
