Seite ii - Protection of the environment requires effective regulatory actions that are based on sound technical and scientific information. This information must include the quantitative description and linking of pollutant sources, transport mechanisms, interactions, and resulting effects on man and his environment. Because of the complexities involved, assessment of specific pollutants in the environment requires a total systems approach that transcends the media of air, water, and land.
Seite ii - Because of the complexities involved, assessment of specific pollutants in the environment requires a total systems approach that transcends the media of air, water, and land. The Environmental Monitoring and Support Laboratory-Las Vegas contributes to the formation and enhancement of a sound monitoring data base for exposure assessment through programs designed to: • develop and optimize systems and strategies for monitoring pollutants and their impact on the environment...

Seite 8 - ... This will be true regardless of whether the in vivo measurements are made with a field fluorometer or an airborne laser fluorosensor. Attempts to circumvent this problem have been made by employing an airborne laser-f luorosensor which sequentially operates at several excitation wavelengths (4,7). The number of laser wavelengths required is dictated by the number of algal color groups anticipated to be present in the surface water sample, with the wavelength of each laser tuned to lie close to...
