Abstract The knowledge about pesticide residue in private wells is not well documented in Sweden.Previous studies have detected pesticide residue in private wells, this issue is what made themunicipality of Laholm commission the study. The purpose was to collect water samples from50 private wells in Laholm and have them analyzed for traces of pesticides. The wells in thestudy are spread geographical over the entire municipality. The analysis of the water sampleswas carried out by the accredited laboratory Eurofins. Nine of the 50 wells in this studycontained residue of pesticides and two of these exceeded the allowed concentration of 0,1 μg/l.Nine different pesticides were detected, among these were BAM, Atrazin and breakdownproducts from Metribuzin. These pesticides were mostly found in older dug wells. The result alsoindicates that occurrence of pesticide residue is more frequent in areas of agricultural activity.These areas should therefore be investigated further. Not all substances that were found are usedfor agriculture. Substances that have been banned for a long time were found in the samples.This highlights the importance of adequate control of new pesticides considered for commercialuse.

Cancer är ett folkhälsoproblem som har ökar världen över med många olika riskfaktorer. De vanligaste cancerformerna är bröstcancer, för kvinnor, respektive prostatacancer, för män. En av de många faktorer som på senare tid belysts är utsattheten för bekämpningsmedel, genom indirekt exponering för dessa via födan. Syftet var att beskriva kopplingen mellan bekämpningsmedelsrester i livsmedel och förekomsten av de vanligaste cancerformerna, prostata- och bröstcancer. Metoden var litteraturstudie då den besvarade syftet. Databaserna som användes var Pubmed och Science Direct, där sökorden som användes utformades genom syftet. 11 resultatartiklar var funna, genom vilka två teman uppkom; Pesticider i animalisk föda och koppling till cancer (1) och Pesticider i odlad föda och koppling till cancer (2). Resultatet visade motsägelser inom området och kunskapsluckor, så som att prostatacancer inte undersökts i samma utsträckning som bröstcancer rörande indirekt exponering. Genom resultatartiklarna visade sig att bioaccumulation, långtidsexponering och indirekt exponering i ”känsliga åldrar” samt närliggande ålder till klimakteriet är nyckelfaktorer för cancerutveckling. Möjlig högriskgrupp är högutbildade medelålders kvinnor. Konklusion: Kunskapsluckor har identifierats och nyckelfaktorer har utvunnits, däribland betydelsen av matvanor. Implikation: Framtida studier skall sträva att vara progressiva och studera skillnaden mellan ekologiskt och oekologiskt odlad föda kring indirekt exponering. / Cancer is an increasing public health problem worldwide, with many risk factors. Themost common cancers are breast cancer, for women, and prostate cancer, for men.Exposure to pesticides through indirect exposure, via food consumption hasrecently emerged as a possible risk factor. Aim of this study is to describe the link between pesticideresidues in food and the presence of the most common cancers. Method was a literature overview. Thedatabases used were Pubmed and Science Direct, in which the keywords derivedfrom the study’s aim. The result was 11 articles through which themes wereformulated; Pesticides in animalistic foods and connection with cancer (1) and Pesticidesin cultivated foods and connection with cancer (2). Results showed inconsistencies in the field and knowledge gaps, asin breast cancer have been studied more than prostate cancer on indirectexposure. Long-term exposure, bioaccumulation, indirect exposure during"sensitive ages" and the adjacent age to menopause are possible keyfactors for cancer development. Possible high-risk group is high educatedmiddle-aged women. Conclusion:Knowledge gaps were identified and key factors discovered, in which eatinghabit was one. Implication: Futurestudies ought to be progressive and possibly study the differences betweenecologically and non-ecologically cultivated foods on indirect exposure.
