Ozone exposure could trigger heart attacks
Pollutants from vehicles, power plants, industry, chemical solvents and
consumer products create ground level ozone by reacting in the presence
of sunlight. Recent studies have linked acute exposure to ozone and death but little is known about the underlying pathways responsible, the
journal Circulation reports on June 26, 2012.
Young, healthy adult volunteers exposed for two hours to
ozone developed physiological changes tied to cardiovascular damage.
They showed evidence of vascular inflammation, a potential reduced ability to dissolve
artery- blocking blood clots, and changes in the autonomic nervous system that controls the heart`s rhythm. The changes
were temporary and reversible in these participants.
"This study provides a plausible explanation for the link between acute
ozone exposure and death," said Robert B. Devlin, senior scientist at
the US Environmental Protection Agency`s (EPA) National Health and Environmental Effects Research Lab, who led the study, according to an
EPA statement. Study participants underwent two controlled exposures - one to clean air
and one to ozone-polluted air - at least two weeks apart. During each
exposure, participants alternated 15-minute periods of stationary cycling and rest.
None of the participants reported complaints or physical symptoms after
inhaling clean air or ozone. However, immediately following and the morning after ozone
inhalation, tests showed significant ozone-induced vascular changes compared to clear-air exposure.
The World Health Organization estimates two million people worldwide,
mostly elderly people with cardiovascular disease, die because of acute
exposure to air pollution. The EPA puts the yearly U.S. toll at 40,000-50,000 deaths.
International Ozone Day 2011
The global theme for Ozone Day 2011
is ‘HCFC Phase-out: a Unique Opportunity’. With the Montreal Protocol, the entire globe agreed to
accelerate the phase-out of production and consumption of hydro chlorofluorocarbons
(HCFCs), but still countries like India has failed to take serious step towards its implementation, says noted
environmentalist Yellapa Reddy.
International Ozone Day 2010
In International Ozone Day 2010 in India a number of competitions were organized for school children to mark this
occasion. These include poster Competition, painting Competition, quiz
on Ozone Science, skit competition, Model Making Competition and slogan writing competition.` Prizes to the winners of these competitions were presented today.Posters, stickers and the 12th edition of the
"The Montreal Protocol: India's Success Story" which contains relevant aspects of India's
commitment to the Protocol were also released on this occasion.
