Abstract
Polarization properties are reported of the background fluorescence of natural water samples obtained from the Providence River and Narragansett Bay. These properties appear to be subject to the same spatial and temporal variability as the unpolarized background fluorescence. Consequently, it is unlikely that significant improvement in the sensitivity of detection of tracer dyes in polluted water can be achieved by using a dye whose polarization properties are complimentary to those of the background.
