Biotestien luotettavuutta tarkasteltiin niiden toistettavuutta vertailemalla: koesarjoja ja pitoisuuksia mitattiin useita rinnakkaisia.

Part of the substances are harmful to environment. Risk assessment and monitoring of synergetic effects is not possible by conducting physical and chemical analysis alone. Therefore toxicological tests and other biological tests have been developed to assess the harmfulness of complex mixtures. Whole effluent assessment have been widely used over the world since the 1980\u2019s but only occasionally in Finland.\n\nAim of the study was to determine the suitability of whole effluent assessment to monitor-ing Finnish treated municipal wastewaters. The reliability of bioassays were studied by comparing test repeatability using comprehensive test sets with many repetitions. The bio-assays chosen to be explored were standardized and commonly used in toxicity testing. Acute toxicity tests conducted were the test of inhibition of bioluminescence of luminescent bacteria and short-term toxicity test to water fleas. Chronic toxicity was studied with algal growth inhibition test. Samples tested were collected from municipal wastewater treatment plants of Klaukkala, Suomenoja and Viikki. Threshold values for harmful responses were tried to determine in order to show if more sensitive test methods should be used. Effects of freezing on toxicity of treated wastewater samples were studied as well.\n\nAs a result of the studies it was indicated that using whole effluent assessment is suitable for monitoring Finnish treated municipal wastewaters. Observations from parallel test series had similar trends almost every time. Variations of response in algal growth inhibition tests were the largest observed. Freezing had no observed effects on the sample when using luminescent bacteria or water fleas as test species. Threshold values for acceptable harmful responses couldn\u2019t be determined because almost zero harmful effects were observed.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Pauli K\u00e4rkk\u00e4inen (pamikark) on 2016-12-13 18:05:12.492421.
