What are the human health concerns? posted on 12:50 PM, June 7, 2016
Particulate matter in the air is monitored because of negative impacts on human health. PM2.5 is of greatest concern because these are tiny particles that can travel deep into the lungs, become lodged and lead to chronic respiratory conditions such as cardiorespiratory disease, decreased lung function, increased respiratory stress, bronchitis, asthma and premature death. Young children, the elderly and people with pre-existing cardiac and respiratory conditions are most susceptible.
What are the sources? posted on 12:49 PM, June 7, 2016
Particulate matter comes from natural sources (such as dust, smoke and pollen) and human-caused sources (wood smoke, vehicle exhaust, combustion products, industry and road dust from sand or other traction material put down in winter).
What are the levels? posted on 9:30 AM, June 7, 2016
Levels of PM2.5 in Kamloops (2011-2013) were 8.2 micrograms (µg)/m3 as the annual average and 20 micrograms (µg)/m3 as the maximum in a 24-hour period. Short-term peaks are often seen during summers with high forest fire activity, notably in 2003 and 2015.
Guidelines for PM2.5 from the Canadian Ambient Air Quality Standards for the BC Southern Interior zone (2013) are a maximum of 10 micrograms (µg)/m3 as an annual average, and 28 micrograms (µg)/m3 as the maximum in a 24-hour period.
