Recent optoelectronic developments have helped scientists and dermatologists to design and improve equipments for the diagnosis of skin lesions. Among the numerous techniques which can be used in dermatology, optical coherence tomography (OCT) represents one of the best options, in terms of skin penetration depth and resolution, for retrieving morphological data of the skin. However, OCT has its own limitations and cannot offer the biochemical information

The present paper aims to evidence the characteristics of drinking water from the point of view of fluorescence spectroscopy. Fluorescence spectra of tap water, both in fresh and old state (i.e. water stored in pipes and in laboratory conditions, for a few days) are compared. The results obtained in this study recommend fluorescence spectroscopy as a first step tool for rapid evaluation of drinking water, with regard to organic contaminants.
