gt;85 %). Concentrations varied significantly across groups, with the highest levels often observed in FC. We identified pesticide use and having pets as important predictors of personal non-dietary exposure. Mixture analysis revealed one major combination (in 72 % of all samples) of three insecticides, namely permethrin, chlorpyrifos, DDE p,p', and the synergist piperonyl butoxide. This study highlights that farm workers using a conventional farming system are a highly exposed group. It is unclear what the identified prevalent mixtures mean for cumulative exposure and resulting health risks.
