Kinetics of selected substances in dermal exposure (polycyclic aromatic hydrocarbons) Skin is one of the largest human body organs and its proper functioning is vital for human body. Dermal exposure represents one of the most important pathways of exogenous substances into the body. Data on kinetics of transdermal absorption of polycyclic aromatic hydrocarbons (PAH) have been yet so far insufficient. Present estimates of health risks level connected to dermal exposure to PAHs, are loaded with great deal of uncertainty. The aim of the dissertation thesis was employment and validation of appropriate testing method of transdermal absorption of substances in vitro and the use of this method to obtain new findings on the influence of concentration, dissolvent and form of application, on the measure of dermal absorption of selected PAH representatives. For the testing of transdermal absorption of substances in vitro, the method using static Franz vertical diffusion cell was chosen. As an absorption membrane, full leather of rear surface of the auricle of a domestic pig was used. Content of analytes in samples of receptor fluid was analyzed by gas chromatography with mass spectrometry (GC-MS) and by high performance liquid chromatography with fluorescence detection (HPLC), for which a new methods was developed and...
