This study investigates spectral characteristics of romaine lettuce at different uptake level of Zn. Also, spectral changes are analyzed to define spectral response of romaine lettuce to Zn uptake. The Zn concentration of control samples range from 0.009 to 0.030 %, whereas that of Zn contaminated samples shows a range of 0.014 to 0.119 %. The Zn concentration dramatically rises from 68th day of experiment...
This study investigated variations of spectral characteristics of Korean pine needles associated with heavy metal contamination at an abandoned Pb-Zn mine. XRF analysis revealed that the pine needles are mainly polluted by Zn and As. Among the contaminants, As content showed highest correlation with surface reflectance in visible and near infrared spectrum where positive relationship in visible and...
