The Air Quality Health Index AQHI and Biomass Smoke in British Columbia

Description 

Biomass smoke is an important source of air pollution associated with a range of cardiopulmonary health conditions in British Columbia (BC) and elsewhere. The Air Quality Health Index (AQHI) is the most widely used tool in Canada to communicate with the public about air pollution. However, its 3-pollutant formulation may not adequately reflect health risks from fine particulate matter (PM2.5) sources such as wildfire, open burning, and residential wood heating. Two studies have been conducted to evaluate the ability of the AQHI and four alternate AQHI-Plus amendments to predict adverse population health effects associated with biomass smoke. Results suggest that a PM2.5-only AQHI-Plus may be better than the 3-pollutant AQHI for communicating about potential respiratory health effects during periods affected by biomass smoke, especially for those with chronic respiratory conditions such as asthma.
