Exposure to Dishwashing Liquid Assessed in University Students from Brest City: A Preliminary Study—A First Approach to Household Products Exposure in France

ABSTRACTIn 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.
