Stilling: Forskningsdirektør
Telefon: 41503043
Seksjon: Ledelse
Thorjørn Larssen er Forskningsdirektør i NIVA og leder Fagsenter for ferskvannsmiljø.
Thorjørn har bakgrunn som forsker innen miljøkjemi og tilknyttede fagfelt som biogeokjemi og økotoksikologi. Hans egen forskning er knyttet til hvordan ulike forbindelser transporterers, omdannes og lagres i miljøet, som er viktig kunnskap for å kunne forstå stoffenes effekter på natur og mennesker og for å vurdere og å prioritere tiltak. Viktigste miljøproblemer Thorjørn har jobbet med er sur nedbør, kvikksølv og organiske miljøgifter, samt hvordan klimaendringer kan påvirke mobilisering og transport av miljøgifter.

Thorjørn er også Professor 2 i miljøkjemi ved Universitetet i Oslo.
