sulfur dioxide @ chalmette

sulfur dioxide exceedances again @Ch_Vista monitor.
September 13, 2011 peak SO2 reading of 196 ppb.  EPA health standard for SO2 is 75 ppb.

In June 2011, Louisiana DEQ recommended a nonattainment status for St. Bernard Parish for sulfur dioxide.  By February 2012,  EPA will confirm and or modify the State's recommendations.  By February 2014, each State must submit a plan of action designed to reduce the concentration of sulfur dioxide in the community's air.  For more information on the new sulfur dioxide health standards click here

The Ch_Vista monitor data is accessible at the LDEQ website , right hand column menu, ON AIR icon, select site data,  select Ch_Vista 

St. Bernard Parish has two other ambient air monitors.  One at Joe Davis Elementary school, called the Meraux site, which is accessible at the LDEQ website, ON AIR menu, select site data, select Meraux. 

The other ambient air monitor in St. Bernard Parish is located in the Murphy Oil area on Ventura Drive.  The Ventura Drive air monitor data is accessible here:     Murphy Oil Monitor 

On September 13 2011, the Ventura monitor sulfur dioxide reading also peaked around the same time of day.  The peak SO2 reading at the Ventura site was 54 ppb.  These readings are averages.  One would need access to the actual SO2 readings to determine peak sulfur dioxide short term exposure.

Our air in St. Bernard Parish is so heavily concentrated with sulfur dioxide, that industries emissions in the aggregate are unhealthily for all community members, and even perhaps seemingly small increments of this chemical will cause adverse health effects  in the community.
