ABSTRACT
Nanotechnologies.offer.broad.promise.to.use.raw.materials.and.energy.more.efficiently..Some.applications.offer.medical.hope.or.environmental.protection..These. rewards,.however,.must.be.balanced.against.the.potential.risks.from.manufacturing,. using,.and.disposing.of.products.containing.nanomaterials..This.chapter.discusses. tools.to.evaluate.the.balance.between.potential.risks.and.rewards,.beginning.with.the. concept.of.Life.Cycle.Analysis.(LCA).
