low levels of air pollution effects can increase risk of cardiac arrest/air pollution effects and causes
According to a study published on Monday, short-term exposure of air pollution effects is related to a better risk of sudden heart problems, especially among older people.
Studies published in the journal The Lancet indicate that low levels of air pollution may also increase the likelihood of cardiac arrest. Study researchers at the University of Sydney say there is an “urgent need” for international guidelines on air quality.
According to the study’s authors, the research is considered to be the largest of its kind ever. He noted data on emergency medical responses in Japan over a two-year period, as well as the country’s record on air pollution that included Particulate Matter.
According to the Environmental Protection Agency, solids and particulate pollution is a mixture of particulate and liquid airborne droplets. Particles made of dust, dirt, soot or smoke, are generated from construction sites, unpaved roads, fields, smokestacks or fires and may contain various chemicals. But most particles are a mixture of pollutants from power plants, industrial and vehicle emissions.
The study focuses on PM2.5, or small particulate matter, which can go deep into the lungs and from there into the bloodstream.
Researchers identified 249,372 cases of out-of-the-home cardiac arrest between January 2014 and December 2015. Cardiac arrest is that the results of electrical disturbances that cause the guts to suddenly stop beating. Heart attack is a cause of sudden cardiac arrest.
About 98.5% of asystole cases were studied while concentrations of PM2.5 were less than the japanese and US standard of 35 micrograms per kiloliter . Approximately 92% occurred, while PM2.5 concentrations were less than the quality of 25 micrograms per kiloliter established by the planet Health Organization.
Researchers found that with a ten microgram per kiloliter increase in PM2.5, there’s a 1–4% increased risk of asystole .
For patients older than 65 years, researchers found a significant relationship between the risk of PM2.5 and increased incidence of cardiac arrest.
Researchers also analyzed data along gender lines but found how PM2.5 affects men and women.
Professor Kazuki Negishi, professor at the Sydney School of Medicine and senior author of the study, supported the findings, stating that “there is recent evidence that there is no safe level of air pollution”.
Nigishi said that “the tendency for air pollution to deteriorate – from the increasing number of cars as well as disasters such as bushfires – effects on cardiovascular events in addition to respiratory diseases and lung cancer – should be noted in health care. Reactions.”
air pollution effects and causes
Researchers have hinted at an increase in air pollution in Australian cities when the country was largely devastated by bushes. In the city of Richmond, west of Sydney, the PM2.5 level has reached quite 500 micrograms per kiloliter – a high level considered safe for humans to breathe. Earlier this month, NASA said that smoke rises from historic blazes affecting air quality in other countries, going “halfway to Earth”.
The study concluded that “to date, no intensity of PM is safe for the overall population,” noting that “assuring current air quality standards considerately for efficient strategies to reduce air pollution Requires as low a level as possible. ”
Several studies published last year also point to threats that harm health from air pollution effects.
Research published by BMJ found a link between particle pollution and hospitalization due to respiratory and cardiac problems. The study also found that air pollution is related to hospitals due to unexpected diseases such as septicemia, kidney failure, skin infection and urinary tract infection.
A 30-year analysis of more than 600 cities in 24 countries found that an increase in air pollution was associated with an increase in related deaths.
In the United States, a study published in the Proceedings of the National Academy of Sciences estimated that more than 100,000 premature deaths in 2011 were related to the risk of air pollution.
