No Evidence of Petroleum Hydrocarbons in 'Good Morning America' Samples

18.08.2010
After receiving a shipment of Louisiana seafood samples collected by a reporter with “Good Morning America,” researchers at Texas Tech University found no evidence of petroleum hydrocarbons.

Though these samples were clean, the sample size was small and more research is necessary before the full picture can be seen, said Ron Kendall, director of The Institute of Environmental and Human Health (TIEHH).

“Our detection limits would have detected selected polycyclic aromatic hydrocarbons (PAHs) had they been there, even at very low levels,” Kendall said. “Everyone should realize the sample size was extremely small and that these data represent just a snapshot of time and space. We believe sampling and analyses should continue, and that independent science-based research needs to continue.”

Scientists are concerned about PAHs because some of them are known carcinogens.

Producers with the morning news program asked TIEHH researchers to test the seafood samples prior to the federal government’s opening of waters to fishing on Monday. Reporter Matt Gutman sent the samples from Bastian Bay, La, where he is reporting.

“We collected the samples Monday in Bastian Bay,” Gutman said. “It is an area where we've found oil on the sediment. We filmed it all, including the bagging. The fishermen used a net, but found no evidence of oil directly on any of the samples.”

Gutman’s samples included shrimp, of which nine were tested from three separate locations, four oysters, two bait fish, a flounder and a speckled trout. They were shipped on ice overnight to the institute on Tuesday and Wednesday, where they were received in excellent condition and smelled fresh before processing.

Once tissues were extracted, scientists analyzed them using gas chromatography with mass spectrometry, said Todd Anderson, an environmental chemist at the institute. The process is used to determine substances within a specific test sample, and is widely regarded as the gold standard for forensic substance identification.

“We were particularly interested in polycyclic aromatic hydrocarbons, some of which can be carcinogenic,” Anderson said. “The analytical results revealed that the PAHs we analyzed for were below detection limits of our instrumentation, and far below any levels of concern as regulated by the U.S. Food and Drug Administration.”

Trace Analysis Inc. of Lubbock, Texas, a certified laboratory in Texas and Louisiana, assisted with the analysis.

This project took five days to complete and was done without support from BP or the United States Federal Government.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
