Gulf animals suffer from lung lesions, other ill effects related to oil exposure
Louisiana Department of Wildlife and Fisheries
The April 2010 Deepwater Horizon oil spill helped spark a massive, ongoing die-off of dolphins in the Gulf of Mexico, a new study suggests.
Dead common bottlenose dolphins (Tursiops truncatus) examined in the region had lung lesions and adrenal gland damage, injuries previously linked to oil exposure, researchers report May 20 in PLOS ONE. Following the blow out at BP’s Macondo well five years ago, researchers have tracked a rising number of unusual deaths and health issues in Gulf dolphins, but have struggled to definitively pin the problems on the spill (SN: 4/18/15, p. 22).
