Marsh Fire Effect on Air Quality

In January 2012 there was a persisent marsh fire in New Orleans East, just north of St. Bernard Parish.  The three air quality monitors in St. Bernard Parish reported high levels of particulate matter and hydrogen sulfide in January 2012.  Both are assumed to be from the marsh fire.

January 23, 2012 was one of the worse air quality days for particulate matter, PM10.  As an example, PM10 hourly readings around the St. Bernard Parish Chalmette Vista neighborhood generally average around the 20 to 40 range, and tend to peak to near 100 on New Year's Eve due to fireworks.  In January,  the PM10 readings at both the Ch_Vista Monitor and another community air monitor on Ventura Drive measured over 300 due to the marsh fire.
