Environmental Pollution (2016)

The coastal preferences of harbour porpoise (Phocoena phocoena) intensify their exposure to human activities. The harbour porpoise Iberian population is presently very small and information about the threats it endures…

Harbor porpoise (Phocoena phocoena) recovery in the inland waters of Washington: Estimates of density and abundance from aerial surveys, 2013–2015

Jefferson, Thomas A.; Smultea, Mari A.; Courbis, Sarah S.; Campbell, Gregory S.
Canadian Journal of Zoology (2016)

The harbor porpoise (Phocoena phocoena (L., 1758)) used to be common in Puget Sound, Washington, but virtually disappeared from these waters by the 1970s. We conducted systematic aerial line-transect surveys…

Polybrominated diphenyl ethers (PBDEs) and their hydroxylated and methoxylated analogues in the blood of harbor, Dall’s and finless porpoises from the Japanese coastal waters

Marine Environmental Research (2016)

This study investigated the accumulation of polybrominated diphenyl ethers (PBDEs) and their hydroxylated and methoxylated analogues (OH-PBDEs and MeO-PBDEs) in the blood of harbor porpoises, Dall's porpoises, and finless porpoises…

Trace element concentrations, risks and their correlation with metallothionein genes polymorphism: A case study of narrow-ridged finless porpoises (Neophocaena asiaeorientalis) in the East China Sea

Liu, Jun; Chen, Bingyao; Jefferson, Thomas Allen; Wang, Hui; Yang, Guang
Science of the Total Environment (2016)

The concentration of trace elements (TEs) and their risk to narrow-ridged finless porpoises (Neophocaena asiaeorientalis) are still unclear. The present study determined the concentration of typical TEs in liver, kidney,…

Organophosphorus flame retardants (PFRs) and plasticisers in harbour porpoises (Phocoena phocoena) stranded or bycaught in the UK during 2012

Papachlimitzou, Alexandra; Barber, Jonathan L.; Losada, Sara; Bersuder, Philippe; Deaville, Rob; Brownlow, Andrew; Penrose, Rod; Jepson, Paul D.; Law, Robin J.
Marine Pollution Bulletin (2015)

A suite of twenty organophosphorus flame retardant compounds have been determined in blubber and liver tissue of twenty harbour porpoises stranded or bycaught in the UK during 2012 in order…

Cetacean distribution in the southern Black Sea: An acoustic approach

Saydam, Gülce
Master's Thesis - Middle East Technical University (2015)

Large numbers of small cetaceans (common dolphin, harbor porpoises and bottlenose dolphins) were hunted in the Black Sea until the hunting of cetaceans was banned in Turkey in 1983. Even…

PLOS ONE (2015)

Reproductive failure in mammals due to exposure to polychlorinated biphenyls (PCBs) can occur either through endocrine disrupting effects or via immunosuppression and increased disease risk. To investigate further, full necropsies…

Accumulation of hydroxylated polychlorinated biphenyls (OH-PCBs) and implications for PCBs metabolic capacities in three porpoise species

Ochiai, Mari; Nomiyama, Kei; Isobe, Tomohiko; Mizukawa, Hazuki; Yamada, Tadasu K.; Tajima, Yuko; Matsuishi, Takashi; Amano, Masao; Tanabe, Shinsuke
Chemosphere (2013)

The present study investigated polychlorinated biphenyls (PCBs) and hydroxylated metabolites of PCBs (OH-PCBs) in blood from three porpoise species: finless porpoises (Neophocaena phocaenoides), harbor porpoises (Phocoena phocoena), and Dall’s porpoises…

Investigations of thyroid and stress hormones in free-ranging and captive harbor porpoises (Phocoena phocoena): A pilot study

Siebert, Ursula; Pozniak, Blazej; Anderson Hansen, Kirstin; Nordstrom, Gwyneth; Teilmann, Jonas; van Elk, Niels; Vossen, Arndt; Dietz, Rune;
Aquatic Mammals (2011)

Increasing anthropogenic activities in the marine environment are potential threats to the health of harbor porpoises by causing unnatural continuous stress to the animals. The present study was a first…
