Cancer. patients:. Kidney. (72,964)*. Indicated. the. highest. concentrations. of. BDE-209. at.
72,964.ng/g.lipid.in.1.kidney.tissue.among.55.patients..Liver.(61,625)*.and.lung.(38,888)*.also.
showed.the.highest.concentrations.of.BDE-209.in.the.liver.and.lung,.respectively,.among.the.
55.patients.studied.
data. of. ΣPBDEs. in. blood. and. serum. samples. between. 1977. and. 2007,. from.
10. countries. (Wang. and. Jiang. 2008).. Results. showed. that. ΣPBDEs. were. the.
highest. in. blood. serum. from. the. United. States,. about. 7-35. times. higher.
than. those. from. Europe. (Table. 7.9),. followed. by. samples. from. Europe. and.
Asia.(Japan.and.South.Korea)..In.general,.ΣPBDEs.from.the.blood.serum.of.
pregnant. mothers. and. their. newborn. babies. from. South. China. were. rela-
tively.lower.when.compared.with.data.from.other.countries.(Luo.et.al..2009,.
Wang.and.Jiang.2008);.for.example,.milk.samples.of.Japanese.women.reached.
291.ng/g.lipid,.which.was.the.highest.among.Asian.countries.(Huang.et.al..
2005).. However,. milk. samples. of. e-waste. workers. in. China. had. extremely.
high. ΣPBDEs. (192.ng/g. lipid),. especially. BDE-209. (270.ng/g. lipid),. with. one.
individual.reaching.72,964.ng/g.lipid.(Zhao.et.al..2009)..The.data.show.that.
the.levels.of.ΣPBDEs.were.much.higher.than.those.of.computer.workers.in.
Spain.(Takumi.et.al..2004).
ImpactsonHumanHealth
Because. PBDEs. are. structurally. similar. to. PCBs,. concerns. have. been. raised.
on.their.possible.adverse.health.effects,.particularly.neurotoxic.effects.in.new-
borns.and.children.(Chao.et.al..2007)..In.fact,.PBDEs.have.been.associated.with.
endocrine.disruption,.reproductive-developmental.toxicity,.including.neuro-
toxicity.and.even.cancer,.due.to.their.common.presence.in.abiotic.and.biotic.
environments. and. in. human. tissues.. A. study. that. used. animals. tested. the.
effects.of.Deca-BDE.exposure.on.maternal.rats.indicated.that.Deca-BDE.and.
its.metabolites.were.passed.onto.their.offspring.through.milk,.which.affected.
their.learning.and.memorizing.ability.(Chen.et.al..2006b,.Jiang.et.al..2009).
Emerging. studies. on. long-term. neurological. effects. of. acute. administra-
tion.of.PBDEs.during.development.suggests.that.these.compounds.can.act.as.
