Air pollution impacts can be heart-stopping: study

There is an increased risk of out-of-hospital cardiac arrest (OHCA) even from short-term exposure to low concentrations of fine particulate matter PM2.5, an international study has found, noting an association with gaseous pollutants such as those from coal burning/mining, bushfires and motor vehicles. The nationwide study of data from Japan, chosen for its superior monitoring, population density and relative air quality, is believed to be by far the largest of its kind. It provides comprehensive evidence of the relationship between PM2.5 and cardiac arrests, using a sample three times larger than all previous research combined and demonstrating the impacts on groups such as the elderly. The study led by the University of Sydney concludes that worldwide, standards should be tightened; the implications also point to the need for cleaner energy sources. Read more......
