Pesticide registration and risk assessment in Hungary

The author presents the main legal steps of the regulation of pesticide registration in Hungary in the past seven decades. The article contains the registration practice applied in the EU, which means also the revision of the active ingredients till 2008-2010. According to the Directive 91/414 EEC, the risk assessement should be performed in every case. This work means the determination of human health (e. g. ADI, ARfD, MRL, AOEL, MAC) and ecotoxicological values (e. g. TER, ETE, PEC, PNEC) furthermore the studying of the fate and behaviour of the active ingredient (e. g. distribution in soil, in surface and ground water, in sediment, in air).
