Emerging Chemicals and E-Waste
There. are. ive. chapters. in. Part. II.. In. Chapter. 7,. an. attempt. has. been. made.
to. review. the. removal. eficiencies. of. some. emerging. chemicals. in. publicly.
owned. sewage. treatment. works.. However,. these. sewage. treatment. works.
were.originally.designed.to.treat.organic.materials.(by.aerobic.and.anaerobic.
decomposition).contained.in.domestic.sewage,.and.are.not.adequate.for.treat-
ing.emerging.chemicals.of.concern,.such.as.antibiotics.and.PPCPS..There.is.
a.danger.of.these.pollutants.entering.into.food.chains.via.the.discharge.of.
sewage.outfalls..Chapter.8.outlines.the.sources,.trends,.and.adverse.health.
effects.of. lame.retardants. used. in.China.. The.stringent.ire.regulations.in.
North. America. and. European. Communities. resulted. in. the. use. of. a. large.
amount.of.lame.retardants.in.these.regions..It.is,.therefore,.timely.to.review.
the.situation.in.China,.which.has.witnessed.a.rapid.industrial.development.
in. the. past. 10. years.. Chapter. 9. demonstrates. the. adverse. health. problems.
of. children. residing. in. Guiyu. (Guangdong. Province),. the. mega. e-waste.
recycling.site.in.China,.based.on.their.manganese.levels.in.blood.and.renal.
tubular. dysfunction.. Chapter. 10. describes. the. health. risks. associated. with.
uncontrolled. recycling. of. e-waste. according. to. the. studies. conducted. in.
Guiyu.as.well.as.another.important.e-waste.recycling.location.(recycling.a.
large. number. of. obsolete. transformers),. Taizhou. (Zhejiang. Province),. and.
reviewed.the.effectiveness.of.existing.regulations.in.controlling.the.problem,.
that.is,.transboundary.movement.of.e-waste.and.toxic.substances.contained.
in.electronic.and.electrical.equipment..Chapter.11.provides.an.overview.on.
the.problems.faced.in.most.countries.and.possible.decision-making.support.
tools.for.managing.e-waste.
Ecological Restoration of Contaminated Sites
Part. III,. “Ecological. Restoration. of. Contaminated. Sites:. Bioremediation,”.
contains. ive. chapters.. Chapter. 12. illustrates. the. potential. of. As. biometh-
ylation. as. a. cost-effective. and. feasible. method. for. bioremediation. of. sites.
contaminated.by.As,.which.is.prevalent.in.several.Asian.countries/regions..
Future. research. on.ield.applications. along.this. line.should. be. encouraged.
as. most. studies. on. As. biomethylation. are. limited. to. laboratory. settings..
Chapter. 13. examines. the. mechanisms. of. homeostasis. of. copper. (Cu),. an.
important. trace. element,. which. is. essential. for. living. organisms,. but. can.
be. toxic. under. high. concentrations.. A. detailed. account. is. given. to. copper.
homeostasis. mechanisms,. which. includes. responses. to. deiciency. as. well.
as.toxic.excess..Similarly,.Chapter.14.focuses.on.another.important.element,.
selenium.(Se),.which.is.an.essential.nutrient.for.living.organisms,.but.is.toxic.
