Here are some Air Quality Action Day tips you can follow to help reduce pollution:

The Lehigh Valley/Berks County Air Quality Partnership encourages residents to consider using public transit or other forms of alternative transportation on all Air Quality Action Days.

Days when ozone levels are expected to be high:

* Conserve electricity and set your air conditioner at a higher temperature.
* Choose a cleaner commute—share a ride to work or use public transportation. Bicycle or walk to errands when possible.
* Refuel cars and trucks after dusk.
* Combine errands and reduce trips.
* Limit engine idling.
* Use household, workshop, and garden chemicals in ways that keep evaporation to a minimum, or try to delay using them when poor air quality is forecast.

Days when particle pollution levels are expected to be high:

* Reduce or eliminate fireplace and wood stove use.
* Avoid using gas-powered lawn and garden equipment.
* Avoid burning leaves, trash and other materials.

This forecast is brought to you by the Pennsylvania Department of Environmental Protection (PA DEP) and the Air Quality Partnership of the Lehigh Valley - Berks Area.

Particle pollution (otherwise known as fine particulates or PM 2.5) is forecasted year round. Being of the photochemical nature, ozone is only forecasted during the summer months (generally from late April to mid September).
