Consumers may be simultaneously exposed to several pesticide residues in their diet. A previous study identified the seven most common pesticide mixtures to which the French population was exposed through food consumption in 2006. The aim of this study was to investigate if the seven mixtures are potentially cytotoxic and genotoxic and if so, whether(More)
Nivalenol (NIV) and deoxynivalenol (DON) are structurally related mycotoxins produced by Fusarium fungi. These fungi typically infest cereal crops such as wheat, maize, barley, oats and rye, and NIV and DON are regularly found in cereal grains, food and feed. Recent risk assessments identified possible data gaps for both DON and NIV in particular with(More)
Due to the broad spectrum of pesticide usages, consumers are exposed to mixtures of residues, which may have combined effects on human health. The PERICLES research program aims to test the potential combined effects of pesticide mixtures, which are likely to occur through dietary exposure. The co-exposure of the French general population to 79 pesticide(More)
Although human populations may be constantly exposed to complex pesticide mixtures through their diet, the human health risk of pesticide exposure is currently assessed on the basis of toxicity data on individual compounds. To investigate the combined toxic effects of pesticide cocktails previously identified in the French diet, we first studied the(More)
Deoxynivalenol (DON) is the major mycotoxin detected in cereal foods and a risk for human health following DON ingestion could not be excluded due to high level exposure. In this light, the hazard of DON must be carefully evaluated. Therefore, the aim of this study is to perform in vitro genotoxicity tests with DON using the Salmonella typhimurium reverse(More)
