Disaster continues: BP oil spill killing dolphins at an alarming rate



By NewsGram Staff Writer

After the 2010 BP oil spill, Dolphins swimming in the oil-contaminated waters of the Gulf of Mexico have suffered from lung lesions and are dying at high rates because of petroleum pollution, as per a recent study.

More than 1,300 bottlenose dolphins have stranded themselves in the northern Gulf of Mexico since early 2010. The recent research links this unusual mortality event to the massive Deepwater Horizon oil spill.

The rise in the death toll of dolphin began shortly before the spill in April 2010, when 4.9 million barrels of oil was spilled into the ocean, and the scientists have struggled to understand whether the two events are related. According to a report of PLOS ONE, all the underwater animals found dead had lung and adrenal-gland lesions that are consistent with exposure to petroleum compounds.

Stephanie Venn-Watson, a veterinary epidemiologist at the National Marine Mammal Foundation said, “Dolphins take big, deep breaths right at the surface of the water, where oil sheens are most concentrated, and where there is a good chance of inhaling oil itself.”

According to the research which compared autopsies of 46 dolphins that were found dead in the spill area had lesions in the lungs and adrenal glands, which regulate hormones and stress response. That’s when researchers came to know that something is wrong with the dolphins.

Kathleen Colegrove, pathologist at the University of Illinois said, “We found that dolphins that died after the oil spill had distinct adrenal gland and lung lesions that were not present in the stranded dolphins from other areas.”

One out of three stranded dolphins in the spill area had a thinned adrenal gland cortex, a rate that was significantly higher than the reference population of stranded dolphins in Sarasota Bay, Florida, in which one in 10 had such a condition.

Colegrove told reporters during a conference call to discuss the findings, “The thinning of the adrenal gland cortex was a very unusual abnormality for us that has not been previously reported in dolphins in the literature. This is something which is latest in a series of research papers on dolphin health in the region after the spill.”

Other differences were also apparent. More than one in five dolphins from the mass-death group had bacterial pneumonia, a serious lung disease that was severe enough to cause or contribute to the animals’ deaths.

Venn-Watson described that inhaling oil can cause adrenal dysfunction, lung disease and bacterial pneumonia, which is one of the most common outcomes of chemical inhalation injury in other animals. Whereas other diseases like brucellosis and morbillivirus are also responsible for increase in the number of deaths.

A 2013 study on cetaceans in Louisiana’s Barataria Bay, found that dolphins were losing their teeth, had lung lesions and high pervasiveness of disease after the worst oil spill in US history.

Venn-Watson added, “Combination of live and dead dolphin analyses, including the latest study, have provided a strong body of evidence. We feel that this study is a critical link in the chain.”

According to figures from the National Oceanic and Atmospheric Administration (NOAA), minimum 1.300 dolphins have washed up in the area of the Gulf of Mexico since the spill. An additional 114 were stranded from February, two months prior to the spill, until April 20.

Geoff Morell, BP senior vice president for US communications and external affairs said, “This new paper fails to show that the illnesses observed in some dolphins were caused by exposure to Macondo oil.” After BP took the issue to the scientific findings.

Trump meets Florida school shooting survivors, suggests arming teachers

US President Donald Trump met survivors and families of the victims that were killed in the Florida school shooting and suggested that teachers and staff members should be provided with arms to avert such massacres, the media reported.

Trump’s comment came during a White House “listening session” on Wednesday which was attended by families and students including six survivors from Marjory Stoneman Douglas High School in Parkland, Florida, where a 19-year-old man Nikolas Cruz armed with an assault rifle killed 17 people on February 14, reports CNN.

The event brought Trump face-to-face with students and parents who have demanded action on gun violence.

“If you had a teacher who was adept with the firearm, they could end the attack very quickly,” he said, stating that schools could arm up to 20 per cent of their teachers to stop “maniacs” who may try and attack them.

“This would be obviously only for people who were very adept at handling a gun, and it would be, it’s called concealed carry, where a teacher would have a concealed gun on them. They’d go for special training and they would be there and you would no longer have a gun-free zone,” Trump said. “Gun-free zone to a maniac — because they’re all cowards — a gun-free zone is ‘let’s go in and let’s attack because bullets aren’t coming back at us’.”

Acknowledging that the idea was controversial, Trump said that his administration would give it serious study.

The President also called for more mental institutions and hospitals in addition to the idea of arming teachers.

Trump’s idea of arming teachers and school staff was met with support from many of the attendees, CNN reported.

Fred Abt, the father of Parkland shooting survivor Carson Abt, said he had discussed with Education Secretary Betsy DeVos that rather than waiting for first responders to arrive, it would be more efficient to have firearms locked on school campuses.

“One possible solution, which may not be very popular, would be to have people in the school, teachers, administrators who have volunteered to have a firearm safely locked in the classroom who are given training throughout the year,” he said.

“There are plenty of teachers who are already licensed to carry firearms, have them raise their hands to volunteer for the training, and when something like this starts, the first responders are already on campus.

Andrew Pollack, a father of one of the 17 victims who died in the Florida shooting, said he was speaking because his daughter couldn’t.

“We as a country failed our children…

This shouldn’t happen.”

The President, flanked by the students, went around the room and shook hands before commencing the session.

Trump also later tweeted he would “always remember” the event, adding “we must keep our children safe”.

“I will always remember the time I spent today with courageous students, teachers and families,” he tweeted, along with a link to the full event.

“So much love in the midst of so much pain. We must not let them down. We must keep our children safe!!” (IANS)
