Observational StudyKinetic Time Courses of Bisphenol-S in Volunteers

Six female volunteers will be exposed orally acute at the reference dose level(0.1 mg / kg bw). For the administration, the product will be dissolved in ethanol (100 mg / ml equivalent to 10 mg / 100 μl) and the solution will be deposited on a cookie (deposit of about 70 μl of solution on a cookie for an individual of 70 kg) and the ethanol is allowed to evaporate before giving each volunteer, with the subsequent consumption of 100 ml of water.

volunteers will be exposed dermally acute at a dose of 1 mg / kg bw. The solution will be applied to an area of 40 cm2 of the forearm and delimited by the indelible marker. The BPS will be added in suspension in an aqueous solution containing 1% of carboxymethylcellulose and administered in the form of drops (70 .mu.l for an individual of 70 kg). The treated area will be left uncoated and unwashed for a period of 4 hours. After 4 hours, the application area will be washed with water and soap. This type of application is therefore similar to an exposure of the general population via the skin (manipulation of cash receipts).
