ABSTRACT
Fugitive metals in the environment are an inevitable consequence of anthropogenic activity. Commercial, industrial, agricultural and other processes result in the release of metals into the soil and water that inevitably affect vegetation. Although there is some variability, excessive metals in the soil and water generally have a negative effect on plant growth and vitality. The effect of metals on plants is often expressed in terms of hyperspectral reflectance characteristics of the plant and there is a long history of monitoring metal stress in plants through spectroscopy and imaging spectroscopy. This chapter presents a review of previous work on the hyperspectral reflectance of the effect of metals on plants.
