The new EQS are based on\nbioavailable concentrations. The problem is that some properties of the waters,\nsuch as dissolved organic carbon (DOC), affect the bioavailability of the heavy\nmetals in different fresh waters. The solution is to estimate EQS-values by using\nbioligand models that can predict acceptable values for different water systems.\nHowever, there are some validation problems when using models to estimate\nvalues for Nordic freshwaters. The first aim of this study was to produce nickel\ntoxicity data for three different freshwaters by implementing chronic toxicity test\nusing the pond snail Lymnaea stagnalis. The data was used to estimate how well the\nthree bioligand models could predict the toxicity values. The second aim was to\ndevelop a L. stagnalis toxicity test method. In two of the three freshwater areas the\nobserved and predicted toxicity values were very similar, in the third however,\nthe observed value was more than double what was predicted. However, all\npredicted values were lower than observed, and it could protect nature in a better\nway. The method developed along with test even though the differences of dry\nweights between concentrations were too small. The method has potential, but it\nneeds more development, especially to optimize the feeding of the test animals.\nThe bioligand models are suitable for estimating the EQS values in Nordic\nfreshwaters. Nevertheless, it is essential to ensure that the background data of the\nmodel is comprehensive and well extensive for the freshwaters being studied.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Maj Rasilainen (manarasi) on 2018-04-20 11:57:43.295494.
