Ozone air quality alerts plague the Philadelphia Region. One of the leading causes of bad air quality is Ground Level Ozone.

Low level ozone (tropospheric ozone) is highly volatile and is created in large part due to vehicle emissions. “Ground level ozone is a serious problem in cities with lots of traffic, such as Los Angeles, Philadelphia, Houston and New York City. In 2013, according to the American Lung Association, nearly four in 10 people in the United States (38 percent) lived in areas with unhealthful levels of ozone.” The use of ethanol in gasoline is causing a dramatic increase in low level ozone.

The harmful ozone is created when partially combusted fuel reacts with the temperature and ultraviolet light. May 2 is early in the season for an ozone alert.

Asthma is a chronic lung disease that affects an estimated 16.4 million adults and 7.0 million children in the United States, regardless of age, sex, race, or ethnicity.(1) Although the exact cause of asthma is unknown and it cannot be cured, bad air quality is believed to be the main cause. In particular, low level ozone is causing an increase in asthma-like symptoms.(2) What many people believe are food allergies are just symptoms of respiratory and immune system damage caused by ozone.

PHILADELPHIA — It is rare to have an air quality alert in the winter; however, Philly has experienced four hazardous air days in a row. Normally air quality alert days are caused by ozone. These air quality alert days are caused by “particle concentrations”.

Forecast Discussion: Tuesday is an Air Quality Action day for the Philadelphia metropolitan area for Unhealthy for Sensitive Groups (USG) or Code Orange particles. An unprecedented air quality event unfolded across the Delaware Valley beginning Saturday night and has continued into Monday. A very strong area of high pressure has created strong surface inversions that have trapped pollutants, allowing particle concentrations to reach the USG range on Sunday and continue into Monday. Typically these types of strong inversions do not develop until later in the winter, when there is snow on the ground. For Tuesday, another strong morning inversion is expected, and very light winds will become calm in the afternoon, which will continue to limit atmospheric mixing. This stagnation will allow USG particle concentrations to extend into Tuesday. **Extended Forecast: By Wednesday afternoon, surface winds will pick up, which should return particles to the upper Moderate range. But on Thursday, a warming trend combined with another episode of stagnating winds may push particles back into the USG range.
