Introduction
Persistent. organic. pollutants. (POPs). are. organic. compounds. that. are. resis-
tant.to.environmental.degradation.through.chemical,.biological,.and.sunlight.
degradation.processes..POPs.are.known.to.persist.in.the.environment.for.long.
periods.due.to.such.properties.and.can.thus.be.capable.of.long-range.transpor-
tation.between.lands,.rivers,.and.oceans..Such.compounds.will.bioaccumu-
late.in.seafood.and.animal.tissues.and.subsequently.become.biomagniied.in.
food.chains.and.ultimately.impact.human.health.and.the.environment..Many.
POPs. are. pesticides. such. as. DDT,. whereas. other. compounds. such. as. PCBs.
