Environment Canada has issued a special air quality statement for Newmarket and York Region.
High levels of air pollution are possible today, with hot and humid weather conditions creating elevated pollution levels.
The air quality statement notes the possibility of deteriorating air quality.
Moderate risk AQHI values are expected throughout the day, with the potential of short-term high risk AQHI values in the afternoon and early this evening, the agency advises.
Individuals may experience symptoms such as increased coughing, throat irritation, headaches or shortness of breath. Children, seniors, and those with cardiovascular or lung disease, such as asthma, are especially at risk.
Exposure to air pollution is particularly a concern for children, the elderly, and those with underlying medical conditions such as lung or heart disease. If you are experiencing symptoms, such as coughing or throat irritation, consider reducing or rescheduling strenuous outdoor activities until the special air quality statement is lifted.
Exposure to air pollution is particularly a health concern for people with heart or breathing problems, those with diabetes, children and the elderly. Stay inside if you have breathing difficulties. Find an indoor place that’s cool and ventilated. Using an air conditioner that cools and filters air may help. If you open the windows you may let in more polluted air.
If your home isn’t air-conditioned, consider going to a public place (library, shopping mall, recreation centre) that is air-conditioned, the agency said.
