Fireworks on Independence Day is credited to Founding Father John Adams who wrote to his wife Abigail that this day “ought to be solemnized with pomp and parade…..and illuminations”.

The Southwest Ohio Air Quality Agency tends to see a spike in particulate matter (PM) at our monitors during July 4, however they are short-lived and often dissipate quickly. Fireworks create smoke and haze that is classified as a fine particle. These particles can be directly emitted from sources such as forest fires, or they can form when gases emitted from power plants, industries and automobiles react in the air.

The health-based standard for PM is for a 24-hour period and fireworks are not typically a concern for the general public because the occurrence is so quick. However, people with respiratory or cardiac issues are more sensitive and have potential to experience health effects from fireworks. These individuals should be aware that fireworks create fine particulates and consider staying indoors during and after fireworks displays.

Enjoy your local fireworks and if you’d like to see real-time PM readings, visit our website.

Bugs! 

Bugs!

The Southwest Ohio Air Quality Agency, as a public service, conducts pollen and mold counts during the work week. We post the results on our website to help residents track their reactions to local allergens. The Agency has a Rotorod sampler on the roof of our main office. Each morning, one of our Monitoring and Analysis team members collects the sample and literally counts and identifies the various pollen grains and mold spores in the sample. We make use of a high-powered microscope.

Well every once in a while, we find a surprise species! If certain insects flourish in wet, humid conditions, then our recent pollen and mold samples support the theory.

Several samples have revealed insect parts or nearly fully-intact bugs on our pollen and mold sampler in recent weeks. The first photo shows the wings of fruit flies. Can you identify the mystery insect in the second photo?
