Abstract:

DEBtox is a user-friendly software package designed to analyze the results of the standard set of aquatic toxicity tests on the basis of the Dynamic Energy Budget theory: acute and chronic tests on survival, the (37d) fish growth test, the (21d) reproduction test with Daphnia and the (4d) alga growth inhibition test.
