TUESDAY, February 11, 2020 (HealthDay News) – Daily exposure to the ozone layer increases the risk of premature death among city dwellers, the researchers warned.
Ground-level ozone – commonly found in cities and suburbs – forms when pollutants react in sunlight.
According to research by co-author Ana Viceso-Cabrera and her colleagues, the new research findings show that thousands of ozone-related deaths "can be minimized according to strict air quality standards." tighter ". She works with the Institute of Social and Preventive Medicine in Bern, Switzerland.
For the study, the researchers analyzed data collected between 1985 and 2015 from 406 cities in 20 countries. They conclude that thousands of deaths could be avoided each year in those cities if their nation had stronger air pollution laws.
The investigators determined the average daily ozone level (above the maximum substrate level of 70 Phases / m3), particulate matter, temperature and relative humidity at each location to estimate the daily number of deaths due to ozone.
More than 45 million deaths have been analyzed. According to the researchers, on average, an increase of 10 10g / m3 in current and previous ozone is associated with an increased risk of death by 0.18%, showing evidence of a potential direct link. , according to the researchers.
The current air quality threshold (in micrograms per cubic meter of ambient air) is: 100 12g / m3 – World Health Organization (WHO); 120 Binh / m3 –…
