Hazard identification of chemical mixtures - techniques of matematical statistics.

Project goals

The hazard identification of chemical mixtures is an objective of the project. The hazard calculated as a sum of hazards of individual chemicals in a mixture can significantly deviate from a real one. This may cause a bad risk assessment. An expresstestof acute toxicity using Tubifex worms, techniques of mathematical statistics (QSAR, ANN) and physicochemical properties of components of a mixture (partition coefficients) will be used to prove the (non) additivity.

    Určení nebezpečnosti směsí chemikálií - techniky matematicko - statistické analýzy.

  • Annotation in Czech

    Předmětem projektu je určení nebezpečnosti (hazardu) směsí chemikálií. Mezi nebezpečností chemických směsí a jeho výpočtem z nebezpečnosti jednotlivých složek za předpokladu aditivity může být významný rozdíl. To může vést ke špatnému stanovení rizika. Kprůkazu (ne)aditivity bude použito rychlého testu toxicity pomocí červů Tubifex , matematicko-statistických technik (QSAR, ANN) a fyzikálně chemických vlastností složek směsi (rozdělovací koeficienty).
