Chinese reasearch links ozone with increased cardiovascular risks

Beijing, Jun 21 (Prensa Latina) A research by Chinese scientifics found that a long exposure to ozone leads to an increase in the risk of suffering fatal heart disease, local press reported.

According to the CGTN channel, the research was carried out by professionals from Fudan University along with the National Center for Disease Control and Prevention and followed 100,000 adults over 18 years of age in this country for nine years.

Among the results, they found that the risks of heart diseases increased by 9,3% among those who were exposed to a 10 micrograms per cubic meter increase in the gas concentration.

These individuals were also more likely to have ischemia and heart attacks in this organ, while those over 65 years of age are the most vulnerable to atmospheric pollution caused by ozone.

Recently, China reported that since the beginning of 2022 there have been high gas concentrations in several cities and described the process to control it as complex due to it affects health, crops and infrastructure.

An official from the Ministry of Ecology and Environment told a press conference that between January and April last year, 339 major cities in the country reported an average density of this element of 127 micrograms per cubic meter, or an 8,5% increase compared to the same period in 2021.

The increase even exceeded 20% in places such as Chengdu, Chongqing and other major metropolises along the Yangtze River.

China has reduced air pollution levels in many cities by 40% over the past five years through measures such as the closure of coal-fired plants, restrictions on vehicle traffic and the use of natural gas.
