A Biogeochemical and Spectral Analysis of Vegetation Affected by External Abiotic Agents: Results of an Investigation from Kitsap County, Washington
Abstract
Biogeochemical and ground-based remote sensing techniques were used in an investigation designed to detect, assess, and monitor hazardous waste disposal activities at several Navy facilities. The investigation was designed to develop a timely and cost-effective strategy for the study of hazardous waste activities. Tissue samples from two tree species (Douglas fir and red alder) were collected from an ordnance burn site and from an electroplating acid waste disposal site near Bangor, Washington. The samples were measured with a spectroradiometer employing Landsat Thematic Mapper bands as well as narrow bandpasses (10 nm) along the red edge. The samples were also analyzed for their elemental content. Control sites were also chosen and sampled. Results showed that red edge reflectance values were significantly different among samples collected at the hazardous waste sites than in samples collected at the control sites. Landsat TM bands 1, 3, and 5 readings were also significantly different. Elemental differences among the plant tissues were less informative. Zinc concentrations, however, were significantly lower on both sites.
