Investigation of seawater pollution on the Black Sea Romanian coast

摘要

The paper presents preliminary laboratory results in an investigation by laser induce fluorescence of the environmental effects on the seawater. The aim of the paper was to analyze the fluorescence of the polluted water in the south area of the Romanian Black Sea coast. The characteristics of the spectral fluorescence of water (intensity, shape, bands) were analysed in connection with the extraction area and pollutants type. The fluorescence spectra are compared with those of natural seawater samples measured at different laser excitation wavelengths (266 nm, 355 nm and 532 nm). Fluorescence spectra of DOM (Dissolved Organic Matter), oil products (OP) and phytoplankton were characterized in correlation with the band of the water Raman scattering and by their specific fluorescence decay. Seawater physico-chemical parameters and chlorophyll concentration were taking into account in seawater pollution analysis.
