Wildfire smoke has long been known to be bad for the health, but now researchers at the University of B.C. say it can cause almost immediate harm to the respiratory and cardiovascular systems. A study from UBC’s school of population and public health, published recently in Environmental Health Perspectives, found that exposure to elevated levels of fine particulate matter during wildfire seasons in B.C. was associated with an increased number of ambulance trips for respiratory and cardiovascular problems only one hour after exposure.
