What to do at moderate levels
Outdoor activity
Fine for most people. If you are planning a long or intense session outdoors, the early morning is usually cleaner.
Sensitive groups
Unusually sensitive people may notice mild irritation. Keep reliever medication to hand if you use it.
Indoor air
Ventilating is still worthwhile. Consider closing up during traffic peaks if you live on a busy road.
