The researchers analyzed & eacute; exposure to fine particles m & egrave ; res of 1767 children before, during and after & egrave ; s pregnancy.
R & eacute; result, women who & eacute; t & eacute; expos & eacute; es & agrave ; a high concentration of fine particles during pregnancy and particularly during the last quarter saw the risks of having a child with autism double.
The link between atmospheric pollution & eacute ; America and autism is more dé emptied during pregnancy before and after & egrave ; s.
& quot; Our r & eacute; results dé show that exposure of pregnant women & agrave ; polluted air & eacute; can have an effect on the occurrence of autism in her child.
The atmosphere & eacute pollution, but America is a factor on which we can act, rel & egrave ; wind authors of dé study.
In dé avoiding exposing pregnant women & agrave ; a polluted air & eacute ;, we r & eacute; would reduce this risk and thereby co & ucirc ; t crescent represents dé feel autism for families and soci & eacute; t & eacute; & quot ;, the researchers.
The fine particles contain toxic substances that p & eacute; n & egrave ; trent in cells and cause oxidative stress.
This can hinder the normal process of d & eacute; development of f & oelig ; tus, including training of the system & egrave ; nervous, the proliferating & eacute; ration and diff & eacute; cell ferentiation can cause cell death programm & eacute; e.
Other dé studies r & eacute; alis & eacute; es in rodents dé also set & eacute; HIGHLIGHTING that fine particles could cause lib & eacute; ration in the blood and brain mol dé particles that stimulate inflammation and alt & egrave ; & egrave rent the system, immune me n & eacute; onatal, recognized processes as causes of autism.
The link could not & ecirc ; be & eacute; ESTABLISHED between inhalation of particles of larger sizes and autism.
