In recent years, more attention has been paid to exposure of the general population to household products. In order to assess exposure, it is necessary to generate exposure data. For this reason, a preliminary study of dishwashing liquid contact on Brest university students was performed. Dishwashing liquid is frequently used and when it is improperly mixed it can liberate harmful molecules. As for university students, they may have a repetitive contact with dishwashing liquid during their academic studies. Relevant parameters as frequency of dishwashing, duration, and amount of dishwashing liquid were assessed from questionnaires and laboratory tests. Tests revealed that overall no difference between the sexes and the type of residential household on dishwashing was present on this population. Amount of washed items and duration was significantly correlated, which could seem logical but remarkable considering the lack of correlation between other parameters. Values of 1.39 and 58.8 μg/kg bw/day for the 95th percentile of dermal and inhalation probabilistic exposure were found, respectively. Dermal exposure coincides with deterministic published data. In the case of inhalation exposure no published data are available. Higher inhalation exposure value may show that dermal exposure is diminished by high dilution of dishwashing liquid in water.
