Determination of polycyclic aromatic hydrocarbons in drinking and surface waters from Galicia (N.W. Spain) by constant-wavelength synchronous spectrofluorimetry.
We describe a fast, new method for determination of the joint concentration of the six polycyclic aromatic hydrocarbons (PAHs), designated by current legislation as indicators of the quality of drinking waters and surface waters intended for the abstraction of drinking waters. The limit of detection of the new method was 6 ng l(-1), its limit of quantification 20 ng l(-1), its precision (CV%) 2.48 and its recovery 94.05%. Its speed allowed rapid PAH screening of 404 samples of surface and drinking water from Galicia (N.W. Spain).
