St. Bernard Parish residents are exposed to a higher than normal level of hydrogen sulfide than most urban areas. http://www.epa.gov/bpspill/h2s.html EPA reports ..."concentrations in urban areas are generally below 1 part per billion (ppb)..." Residents in St. Bernard Parish tend to be exposured to a range of 2ppb to 4 ppb on a daily basis.
Louisiana DEQ reports levels of Sulfur Dioxide around 12 ppb SO2 trigger headaches and other adverse quality of life issues. EPA's sulfur health standard is 75 ppb SO2 for a one-hour reading. There have been studies "to test whether prior exposure to a low concentration of ozone would condition airways in asthmatic subjects to respond to a subthreshold concentration of sulfur dioxide."
We are the science for what happens to healthy airways and lungs exposed to higher levels of sulfur dioxide mixed with this level of hydrogen sulfide and particulate matter.
