The Air Quality Index Explained: What It Means and How to Stay Safe

By Adeel Hassan NY Times, Aug. 6, 2021

The Air Quality Index measures the density of five pollutants: ground-level ozoneparticulatescarbon monoxidenitrogen dioxide, and sulfur dioxide. It was established by the Environmental Protection Agency as a way to communicate to Americans the cleanliness of the air they are breathing each day. Read more

DEP declares air quality action day for July 20

Harrisburg, PA – The Pennsylvania Department of Environmental Protection (DEP) has issued a Code Orange Air Quality Action Day for fine particulate matter for Tuesday, July 20, 2021, in the following areas of Pennsylvania:

• The southeastern counties of Bucks, Chester, Delaware, Montgomery, and Philadelphia;
• The Lehigh Valley-Berks Area which includes the counties of Berks, Lehigh, and Northampton;
• The southcentral counties of Cumberland, Dauphin, Lancaster, Lebanon, and York; and

*** Sunday’s forecast: Conditions will be favorable for ozone concentrations on Sunday to climb into the code ORANGE range. Light southwesterly flow around a strong area of high pressure combined with sunny skies will allow for the rise in concentrations. Fine particulate will also go into the lower moderate range as well.

Residents and businesses within the ozone Air Quality Action Day area are strongly encouraged to voluntarily help reduce air pollution by:

• Conserving electricity by setting air conditioning to a higher temperature;
• Combining errands to reduce vehicle trips;
• Limiting engine idling; and
• Refueling cars and trucks after dusk.

This forecast is brought to you by the Pennsylvania Department of Environmental Protection (PA DEP).

Wildfires can affect air hundreds of miles away

Wildfires can cause temporary large increases in outdoor airborne particles, and substantial increases in gaseous air pollutants such as carbon monoxide, nitrogen dioxide, formaldehyde, and acetaldehyde.  Large wildfires can increase air pollution over thousands of square kilometers [or thousands of square miles].

NASA Satellite Data Show 30 Percent Drop In Air Pollution Over Northeast U.S.

Over the past several weeks, NASA satellite measurements have revealed significant reductions in air pollution over the major metropolitan areas of the Northeast United States. Similar reductions have been observed in other regions of the world. These recent improvements in air quality have come at a high cost, as communities grapple with widespread lockdowns and shelter-in-place orders as a result of the spread of COVID-19. Read more …
