Prediction of Acute Toxicity of Emerging Contaminants on the Water Flea Daphnia magna by Ant Colony Optimization - Support Vector Machine QSTR models

21-Feb-2017 | Reza Aalizadeh; Peter Carsten von der Ohe; Nikolaos S. Thomaidis, Journal of Environmental Monitoring, 2017

According to the European REACH Directive, the acute toxicity towards Daphnia magna should be assessed for any industrial chemical with a market volume of more than 1 t/a. Therefore, it is highly recommended to determine the toxicity at a certain confidence level, either experimentally or by ...

Energies, Vol. 10, Pages 247: Environmental Assessment of Possible Future Waste Management Scenarios

19-Feb-2017 | Arushanyan, Yevgeniya ; Björklund, Anna ; Eriksson, Ola ; Finnveden, Göran ; Ljunggren Söderman, Maria ; Sundqvist, ..., Energies, 2017

Waste management has developed in many countries and will continue to do so. Changes towards increased recovery of resources in order to meet climate targets and for society to transition to a circular economy are important driving forces. Scenarios are important tools for planning and assessing ...
