Dear Marmam Community,

My co-authors and I are pleased to share our new paper:

Mihova, S., Doncheva, V., Stefanova, K., Stefanova, E., Popov, D., 
Panayotova, M. Plastic ingestion by /Phocoena phocoena/ and /Tursiops 
truncatus/ from the Black Sea in the book: Environmental Protection and 
Disaster Risks

DOI: 10.1007/978-3-031-26754-3_26 


Abstract: Stomach contents and intestines of two species of cetaceans 
from the superfamily toothed whales (Odontoceti), collected in the 
western part of the Black Sea during the period 2020–2021 were inspected 
for the presence of plastic particles. Microplastics (<5 mm) were found 
in all 2 bottlenose dolphins (/Tursiops truncatus/ ssp. /ponticus / 
Barabash-Nikiforov, 1940) from the dolphin family (Delphinidae) and 
micro- and mesoplastics (5–25 mm) were found in 24 of 29 harbour 
porpoises (/Phocoena phocoena/ ssp./relicta/ Abel, 1905) from the 
porpoise family (Phocoenidae). A total of 197 plastic particles were 
recorded in 26 individuals (84% of all individuals examined, 21 of 25 
female and 5 of 6 male animals). The average number of plastic particles 
per cetacean was 6.35 ± 6.92 par.ind., ranged 0 to 25 per individual. 
The most common type of plastic identified were fibres (43%) and 
fragments (36%). The most frequent plastic colour recognized was grey, 
blue and black.

Keywords: Microplastics, Black Sea, Cetaceans, Harbour porpoise, 
Bottlenose dolphin
