![]() “Extreme temperature events are becoming more frequent, longer and more intense, and their adverse health effects have drawn growing concern,” said senior author Yuewei Liu, an association professor of epidemiology in the School of Public Health at Sun Yat-sen University in Guangzhou, China. Ultimately, researchers estimate up to 2.8% of heart attack deaths may be attributed to the combination of extreme temperatures and high levels of fine particulate matter pollution. It was 74% higher during a four-day heat wave when the temperatures ranged from 94.8 to 109.4 degrees Fahrenheit.ĭuring cold days, when the temperatures ranged from 33.3 to 40.5 degrees Fahrenheit for two days, the risk was 4% higher. At that temperature, during a two-day heat wave, the risk of dying from a heart attack was 18% higher. Rather, extreme high temperatures were considered a range between 82.6 to 97.9 degrees Fahrenheit. ‘It comes up on you fast:’ Scorching heat is crushing American businessesĮxtreme temperatures did not mean that the thermometer had to hit 100 degrees Fahrenheit. Kyle Ledeboer/Arizona Wilderness Brewing Co. Cold snaps and high pollution days didn’t seem to have the same increase.Īrizona Wilderness Brewing's downtown area location's patio on July 20 in the afternoon. On days when the pollution was above 37.5 micrograms per cubic meter and a heat wave lasted four days, the risk someone would die from a heart attack was twice as high than usual. ![]() Long-term exposure can cause cancer, stroke and heart attack. The particles cause irritation and inflammation and can lead to respiratory problems. ![]() Instead of being breathed out, it can get stuck in the lungs or go into the bloodstream. It’s so tiny - 1/20th of a width of a human hair - that people can’t see it, and it can travel past the body’s usual defenses. This study focused on the harm caused by the tiniest particulate matter: PM2.5. Cars, agriculture, unpaved roads, construction sites and wildfires can also create it. Particulate pollution comes from coal- and natural gas-fired plants. Particulate matter, or particle pollution, is the mix of solid and liquid droplets floating in the air, according to the Environmental Protection Agency. It can come in the form of dirt, dust, soot or smoke. ![]() Older people and women seemed to be most at risk. When there was extreme heat combined with high pollution levels, people faced the greatest risk that they would die from a heart attack. It includes risk identification, assessment. Risk analysis is an essential component of project risk management, which is the overall process employed by project managers to lessen the impacts and deal with risk. It’s so hot in Arizona, doctors are treating a spike of patients who were burned by falling on the ground Risk analysis is about understanding what could go wrong with a project and then evaluating the probability of each risk occurring.
