Air tests from the Louisiana coast reveal human health threats from the oil disaster
Today the Louisiana Environmental Action Network released its analysis of air monitoring test results by the Environmental Protection Agency. The EPA's air testing data comes from Venice, a coastal community 75 miles south of New Orleans in Louisiana's Plaquemines Parish.
The findings show that levels of airborne chemicals have far exceeded state standards and what's considered safe for human exposure.
For instance, hydrogen sulfide has been detected at concentrations more than 100 times greater than the level known to cause physical reactions in people. Among the health effects of hydrogen sulfide exposure are eye and respiratory irritation as well as nausea, dizziness, confusion and headache.
The concentration threshold for people to experience physical symptoms from hydrogen sulfide is about 5 to 10 parts per billion. But as recently as last Thursday, the EPA measured levels at 1,000 ppb. The highest levels of airborne hydrogen sulfide measured so far were on May 3, at 1,192 ppb.
