Acknowledgements Det har varit en rolig tid, om än rätt intensiv på slutet, och det är många jag har att tacka för att denna avhandling har blivit till! Tack Malin Brändén Åkerblom som väckte mitt intresse för kemi och som handledde mitt examensarbete: ”Gaskromatografisk restbestämning av ogräsmedlet bromofenoxim” långt före (som det känns) datorernas tid (det fanns dock telefon). Tack mina handledare Göran Odham och Michael McLachlan. Ett speciellt tack till Michael för ditt starka stöd på sluttampen. Tack till Zoofysiologerna i Göteborg för det inspirerande tvärvetenskapliga samarbetet. Tack Lars Förlin för att du alltid ställer upp och tar dig tid med mina frågor, Jari Parkkonen för att du räddade fiskarna undan kvävningsdöden, Joachim Sturve för att du aldrig är främmande för nya projekt, Eirikur Stephensen likaså för värdefullt samarbete. Tack Joakim Larsson för ditt stöd, alla spännande projekt och din okuvliga energi. Tack Erik Lindesjöö som till slut rodde det otursförföljda försöket i hamn. Tack alla övriga medförfattare. Tack Lillemor, min biträdande handledare för att du alltid ställer upp som stöd och bollplank och dessutom fixar hemtransport efter festerna. Tack min mångåriga labkompis Maria för allt vårt samarbete, dina kreativa alster och att du älskar att dansa lika mycket som jag. Tack för stöd och hjälp med allehanda ting till övriga kära arbetskamrater på Mo. Tack Uffe för ditt stöd och din kreativa händighet. Tack Carina, Malin, Ulrika, Mats och Kattis. Tack Tomas som tålmodigt ställer upp med kloka råd, Micke som förgäves försökt lära mig datorernas hemligheter, Ulla E, Kerstin, Ulla S, Anna-Lena, Cindy, Bosse, Lotta, Ann-Sofie, Lisbeth och Anna-Karin. Tack alla övriga ITM:are och miljökemister för trevlig samvaro och fruktbart samarbete. Tack Cajsa för allt trevligt samarbete genom åren. Ett speciellt tack till Amelie, som aldrig ger upp, för all hjälp och stöd, för alla intressanta och givande vetenskapliga diskussioner för att inte tala om alla andra kreativa stunder och dina fantastiska kreativa skapelser. Vi kommer garanterat att bli rätt gamla, du och jag. Slutligen ett tack till min stora underbara familj som sett till att jag inte bara ägnat mig åt gallanalyser. Jag önskar bara att pappa hade levat! 20 References Aas,E., Baussant,T., Balk,L., Liewenborg,B. and Andersen,O.K. (2000).
