Breathe now, soot season on its way

People are getting a breather between dirty-air seasons right now in the San Joaquin Valley — ozone season is almost gone and soot season hasn’t quite started.

Which is worse, ozone or soot? It’s definitely soot, which is my shorthand term for specks of soot, chemicals and other microscopic debris.

These specks account for the vast majority of early mortality related to dirty air.  In the air-quality community, the specks are known as PM-2.5.

About 670 premature deaths will be eliminated by 2019 when the region is supposed to achieve the PM-2.5 standard, according to the San Joaquin Valley Air Pollution Control District.

Where are the deaths occurring? Kern County has nearly a third of them with 207 a year, according to the research. Fresno County has 172. Tulare County has 86.

There’s a lot of other folks suffering, too.

Research shows there will be reductions hospital admissions related to heart attacks and asthma. More than 125,000 days of lost work will be eliminated.

When you add up all costs for those non-fatal health problems, you get $102 million total, the air district says.
