Gulf oil spill: Fouling air as well as water?
The EPA says some communities in Louisiana face a 'moderate health risk' due to hydrocarbon fumes from the Gulf oil spill. Researchers will report air quality findings this week.

New Orleans resident Amzie Adams said he first noticed an unusual gas smell in the French Quarter and surrounding neighborhoods a week after the oil spill disaster started. An artist who’s been diagnosed with liver disease, Adams gave up using oil paints decades ago because the fumes affected his health.Skip to next paragraph
“I’m one of those people who’re particularly sensitive to chemical fumes, and for the past two months I’ve really noticed something in the air, and I think it has to come from the spill,” says Mr. Adams. He reported his experience to a regional Poison Control office and has since received dozens of follow-up calls monitoring his health.
“Sometimes it’s smelled like methane gas, sometimes like a gas station," Adams said. "My eyes have been burning for two months now.”
Kura, of the University of New Orleans, is heading an interdisciplinary research effort examining air quality issues related to the spill, which will include scientists from several universities. Their research will rely in part on inverse modeling, a reverse methodology that will use air quality samples to estimate the actual size of the spill, he said.
“You have a vast area with unknown millions of gallons of crude, so it’s not as easy as measuring emissions from a smokestack,” said Kura. “The measurements you get at one point on a given day are dependent on the wind direction, so you have to measure over time to get a good idea of what the exposures are.”
The multi-pronged study will also look at water quality issues, including whether soot and other pollutants created by burn-offs of oil in the Gulf have created acid rains and so-called “black rains,” which may affect groundwater and soil compositions.
“Air pollution is by far the most important factor in terms of human health, but the particulates created by burning oil on the surface are particularly toxic, and when they go up in the clouds they will come down with the rain,” Kura said.
Anna Hrybyk, of the Louisiana Bucket Brigade, said her organization is distributing air sample self-collection kits to residents of the Gulf region. The samples are sent to an independent lab for testing. The non-profit’s website includes an interactive map, which is relying on “crowd sourcing” to collect data about the spill.
Using e-mail, text messages, or by visiting the group's website, users can make their own reports regarding odors, ill health, oil on beaches, oiled wildlife, and a host of other impacts from the spill. The site has recorded 1,300 oil impacts since May 1, including 200 reports of vapor odors, she said. [Editor's note: The original paragraph has been changed to give the correct number of reports of vapor odors.]
“Regarding people as far away from the spill as New Orleans saying they can smell the hydrocarbons, I believe that is quite possible,” said Kura. “Some people are very sensitive to exposure, and it all depends on whether a plume of these vapors is over their area. On one day it could be yes and on another no.”
