These activities include refueling vehicles or topping off when refueling, using gasoline powered lawn equipment, and using charcoal lighter fluid. Positive activities include car pooling, biking to work, delaying or combining errands, and using water based paints. In addition, smoke originating from wildfires in Quebec and Ontario, Canada will continue to impact PM2.5 concentrations at the surface across much of northern lower Michigan through Saturday, July 1st.
