The field-based video spectral survey of the visible-near infrared range 0.4–0.9 μm makes it possible to confidently record “spectral anomalies” of plants exposed to a single adverse effect of contamination with heavy metals (copper, lead, nickel, cadmium) using a video spectrometer mounted on a rotating platform. Anomalies for different plant species and different pollution levels are fixed mainly in the near-IR range of 0.7–0.9 μm in the early stages of exposure (from several days) long before the appearance of apparent morphological changes in plants. Field video spectral survey is a fast and effective method of studying the patterns of formation of these anomalies, their detection and mapping due to the possibility of obtaining in real time spectral information (series of monochrome images and outgoing radiation spectra) of large areas with background and test objects. The values of “spectral anomalies” and the duration of their existence make it possible to conclude that they can be registered and monitored by aerospace video spectral systems of high spectral and spatial resolution.
