A new Chinese study links prolonged exposure to air pollution with a high risk of developing autism in children.
A team from the Chinese University of Science, in collaboration with the University of Birmingham (UK) and McGill University (Canada), investigated the relationship between long- Air Pollution and Autism spectrum disorders (TSA) among children in developing countries.
The researchers studied 124 children with ASD and 1,240 children who had not undergone a control group at different periods over nine years.
The study focuses on three topics: PM1, PM2.5 and PM10, Fine particles Suspended in the air from factories, dimming, construction and roadside dust.
The finer the particles, the more they enter the lungs to enter the blood, where they cause many disorders.
PM1 is the best particle, followed by PM2.5 and PM10. Few studies have been done on these particles and have some safety standards.
Published in the journal International Environment, the results of the researchers show thatexposure Particles of matter (PM2.5) from birth to age three will result Risk Development of TSA plus 78%.
These findings are in line with previous findings linking prenatal exposure to air pollution with ASD in children.
"The causes of autism are complex He still did not understand enough Environmental factors Are increasingly taken into account. They are in addition to other factors, genetic"Explains Professor Guiding Guo, author of the study.Early childhood brain development is more exposed to toxic exposure to the environment. Several studies have shown that this may affect brain and immune function. This can explain the link detected between pollutants and ASDs. But further research is needed to further explore the relationship between Air Pollution and Mental health in general"He said.
Associate Professor Yuming Guo of Monash University in Australia commented on these observations: "The serious health effects of air pollution are known and there is no safe threshold for exposure. Even exposure to a small amount of small particles can lead to premature birth, school delays, and health problems, including heart failure"He said.
