    Project Details


    Chemical analysis have been developed to detect and measure organic compounds in soil and water. Though, if transformation by biological or chemical processes has occurred, an analysis often fails to detect the metabolites/end-products formed during the transformation. Biotests are supplements to the normal analytical program and should be used in addition to chemical analysis. Biotests can also be used as screening-tests where many samples are analyzed biologically. Samples showing toxicity in the tests are then selected for further chemical and biological investigations.
    In the project, focus is on components from creosote and oil products. The degradation of compounds are followed by chemical analysis but concomitantly biotests are conducted to reveal if any metabolites are formed The toxicity is determined as the inhibition of nitrification measured by MINNTOX, by the Biotox-test, and by the toxicity to Daphnia and algae.
