Heavy Traffic And Air Pollution Linked To Dementia
A recent study in the Ontario environment has raised general health
worries about the effect of air pollution and traffic. The study also found out that individuals who lived within 50 meters of a heavy traffic environment had
a 7% higher risk of dementia when compared with individuals who lived more
than 300 meters far from such
environment.
The result
of this research discovered 243,611 instances of
dementia, 31,577 instances of Parkinson's disease, and 9,247 instances of multiple sclerosis within the Ontario environment between 2001 and 2012 when they
mapped each individual’s
closeness to major roadways, utilizing the postal code of their living arrangement. The
discoveries show that living near major roads with heavy traffic increases the risk of dementia, however not
Parkinson's disease or multiple
sclerosis, two other major neurological health issue.
According
to one of the lead researcher, Dr. Hong Chen, environmental and occupational health
researcher at PHO and an adjunct
scientist at ICES, Little
is known in current studies about
how to lessen the danger of dementia. The discoveries made
in this study demonstrate the nearer you are to environments with heavy everyday traffic, the greater the danger of developing dementia. With our increasing exposure to traffic
activities and the more inclination for individuals to live in urban areas, this has serious public health implications.
This study
is the first in Canada to recommend that pollutants from heavy
everyday traffic are
connected to dementia. Although
it has been well documented that air pollutants can get into the circulation
system and prompt inflammation,
which is connected with cardiovascular diseases and perhaps different conditions, such as diabetes, study proposes that air pollutants can get
into the brain by means
of the blood stream and can
lead to neurological issues.
As urban environments
turn out to be all the more populated and more congested with vehicles
on major roads, this study could be utilized to
help advise municipal land use
decisions and building
designs to consider air pollution factors and the effect on public health.
