In-Depth Information
(Beijing,. Hubei,. Hunan,. Shaanxi,. Sichuan,. Jiangxi). for. comparing. heavy.
metal.loadings.in.children.with.autism..A.general.trend.was.observed.show-
ing. that. samples. (hair,. blood,. and. urine). from. coastal. districts. tended. to.
contain.higher.mercury.and.cadmium.whereas.those.from.inland.districts.
higher.lead.and.arsenic.(although.no.statistical.differences.were.observed.
due.to.small.size.of.some.samples).
Gender Difference
Among. the. 111. children. with. autism. from. Mainland. China,. 101. (90.99%).
were. male. and. 10. (9.01%). were. female,. and. among. the. 71. children. with.
autism.from.Hong.Kong,.64.(90.14%).were.male.and.10.(14.08%).were.female..
In.general,.male.children.with.autism.made.up.90%.of.all.the.children.with.
autism.from.both.Mainland.China.and.Hong.Kong.
Food Allergy
The. patients'. blood. IgG. (from. The. Great. Plains. Laboratory,. Inc.,. Lenexa,.
Kansas).was.tested.to.analyze.the.food.allergy.of.these.children.with.autism..
It.was.observed.that.these.children.were.sensitive.to.grains.(e.g.,.wheat,.rye,.
oats,. barley,. gluten),. dairy. products. (e.g.,. milk,. cheese,. whey,. yogurt),. and.
other.food.items,.such.as.egg.white,.egg.yolk,.sugar.cane,.asparagus,.carrot,.
and.citrus.fruit.
Discussion
Body Loadings of Heavy Metals
The. children. with. autism,. both. from. Mainland. China. and. Hong. Kong,.
accumulated. extremely.high.concentrations.of.heavy. metals.in.their.bod-
ies..In.Mainland.China,.heavy.metal.pollution.caused.by.both.metal.min-
ing.and.smelting.and.other.industrial.activities.is.very.serious..In.addition,.
the. use. of. gasoline. and. paints. containing. lead. and. pesticides. containing.
arsenic. explains. why. higher. levels. of. these. two. elements. were. detected.
in. children. from. Mainland. China.. A. survey. conducted. by. WHO. in. 2004.
indicated.lead.poisoning.of.children.in.many.parts.of.China..Among.17,141.
children.examined,.it.was.revealed.that.1,791.children.had.blood.lead.con-
tent.that.exceeded.100.μg/L,.with.lead.poisoning.rate.reaching.10.45%.(Sina.
News.Centre.2005)..On.the.other.hand,.the.high.concentrations.of.mercury.
and.cadmium.observed.in.children.with.autism.from.Hong.Kong.and,.to.
certain.extent,.from.other.coastal. districts,.may. relect.the.intake.of.these.
two.heavy.metals.through.consumption.of.ish.and.shellish.as.these.two.
