Pesticides in foods : bachelor thesis

Preokret u uporabi pesticida dogodio se otkrićem diklordifeniltrikloretana (DDT-a) kad je počela i prva komercijalna proizvodnja istih.Danas je njihov broj izrazito velik, a uporaba raširena. Sve to dovelo je do velike zabrinutosti obzirom na njihovu dokazanu toksičnost, potencijalni kancerogeni učinak, štetan učinak na okoliš, ali i na ljudsko zdravlje.
