Case background

Case background

  • DDT – Dichloro–Diphenyl-Trichloroethane

  • DDT as a way of preventing malaria

  • Malaria facts:

    • 2-3 million deaths annualy

    • 350 – 500 million people affected

    • Economic loss (1/2 billion dollars per year)

    • Threat of 40% world population

    • Mostly affect poor, developing countries

  • Since 1939 DDT is commonly used for fighting against malaria


The problem

The problem

  • Long half-life length (up to 15 years),

  • Bio-accumulates in human body and environment,

  • Passedfrommotherto infants during breast feeding

  • No one ever died from sprayed DDT

  • No proofs that it cannot lead to death nor environment pollution (asbestosexample).

  • UNO considers banning usage of DDT -> less polluted environment but higher amount of malariainfections.
