Identification of pesticide mixtures and connection between combined exposure and diet

Camille Béchaux, Mélanie Zetlaoui, Jessica Tressou, Jean-Charles Leblanc, more

Food and Chemical Toxicology > 2013 > 59 > Complete > 191-198

The identification of the major associations of pesticides to which the population is exposed is the first step for the risk assessment of mixtures. Moreover, the interpretation of the mixtures through the individuals’ diet and the characterization of potentially high-risk populations constitute a useful tool for risk management. This paper proposes a method based on Non-Negative Matrix Factorization...
