"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
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.
Testing data also shows levels of volatile organic chemicals that far exceed Louisiana's own ambient air standards. VOCs cause acute physical health
symptoms including eye, skin and respiratory irritation as well as headaches, dizziness, weakness, nausea and confusion.
Louisiana's ambient air standard for the VOC benzene, for example, is 3.76 ppb, while its standard for methylene chloride is 61.25 ppb. Long-term
exposure to airborne benzene has been linked to cancer, while the EPA considers methylene chloride a probable carcinogen."
