air quality alert issued for St Bernard Parish

This morning LDEQ issued an Air Quality Alert for St Bernard Parish because the level of Sulfur Dioxide concentration violated the health standard.  An SO2 alert was also issued yesterday evening.

Sensitive groups, like children, the elderly, people with COPD, respiratory issues, and asthma, should restrict outdoor activity.

""In terms of the recent exceedances, it appeared that whatever emissions overages had occurred, likely at parish refineries, had ceased by Friday afternoon.
The most recent sulfur dioxide spike above the 75 parts per billion sulfur dioxide standard at the DEQ's Chalmette Vista monitoring station was a 90 parts per billion reading, recorded at 10 a.m. Friday.
That marked the fourth exceedance since Thursday, with the highest overage being a 112 parts per billion reading at 9 p.m. Thursday.""
LDEQ has changed access to air monitor data.
