The Ministry of Environment in collaboration with Northern Health has issued an Air Quality Advisory for Kitimat.
Environment Canada says it’s because of high concentrations of fine particulate matter that are expected to persist.
They say people with chronic underlying medical conditions shouldn’t do strenuous exercise until the advisory is lifted.
They say staying indoors and in air conditioned spaces helps to reduce fine particulate exposure.
Exposure is particularly a concern for infants, the elderly and those who have diabetes, and lung or heart disease.
Restrictions on open burning are also in effect for parts of the Kalum Timber Supply Area.
