Researchers have have found a link between autism and air pollution.
As if the smoggy haze that turns horizons brown is not proof
enough that air pollution is a problem, many cities issue air-quality
warnings that warn people to limit time outside, keep windows closed and
air conditioning on to filter out the pollutants.

Prenatal exposure to air pollution shows an increased risk for autism.

The respiratory dangers of air pollution have long been known, but is
has been unclear what other effects it really has, and specifically
what effects it has on unborn babies and infants.
A new study published on June 18, 2013 in the journal Environmental Health Perspectives links
air pollution to increased autism risk. The six chemicals that were
included in the study that had statistically significant correlations to
occurrence of Autism Spectrum Disorder (ASD) are known neurotoxins that
are also known to pass from mother to baby during pregnancy.

Combine the two studies, and it starts becoming apparent that air pollution from traffic has a much larger impact on our children than we previously thought. Factor in the increase in cars and traffic over the recent years, and it becomes alarming to think about what effects increases in traffic pollutants may produce.

The study looked at children born in all 50 states after 1987, the
first year air pollution data were available, and through 2002. While
researchers say that the study produced strong results showing a link
between an increased rate of ASD and air pollution, specifically
traffic-related pollutants, they cannot name a single factor as
responsible for the increase. The data are not specific enough to
pinpoint which of the pollutants is causing the link. Researchers
caution further study is needed.
As of right now, researchers have yet to find a specific cause of
ASD. Rather, they think it is a combination of factors that includes
maternal age, genetics and environmental factors. This study identifies
just one potential environmental factor, but doctors emphasize that this
study does not show a cause for autism, just an increased risk.According to the researchers, 11 percent of the US population lives
within 100m of a four-lane highway, and nearly 40 percent of children
attend school within 400m of a major highway. ****************************************************** |
The June 18 study is not the only one to raise questions about the
effects traffic-caused air pollution can have. A study published on May 31, 2013
in the same journal looked at elemental carbon attributed to traffic
(ECAT) exposure during infancy. The study took data from groups that
lived less than 400m from a highway, or more than 1500m away. It found
that those children with high ECAT exposure (i.e., those who lived
closer to highways) during the first year of life were 70 percent more
likely to be hyperactive by age seven.
