has done extensive research into autism
In a recently published study in the journal Biological
Trace Element Research, Arizona State University researchers report that
children with autism had higher levels of several toxic metals in their blood
and urine compared to typical children. The study involved 55 children with
autism ages five to 16 years old compared to 44 controls of similar age and
gender.
The autism group had significantly higher levels of lead in
their red blood cells (+41 percent) and significantly higher urinary levels of
lead (+74 percent), thallium (+77 percent), tin (+115 percent), and tungsten
(+44 percent). Lead, thallium, tin, and tungsten are toxic metals that can
impair brain development and function, and also interfere with the normal
functioning of other body organs and systems.
