Description/Abstract | Leaves of Lycium andersonii A. Gray from 20 different shrubs from the northern Mojave Desert were collected.^ Half of each sample was washed in 1/10 N HCl followed with deionized water before analysis in triplicate by optical emission spectrometry, and the other half was analyzed unwashed.^ Washed samples contained 12, 35, 33, 40, 55, 47, 57, 8, 8, 9, and 20 percent, respectivey, less calcium, zinc, copper, iron, aluminum, silicon, titanium, strontium, barium, lithium, and lead than did unwashed leaves.^ The losses probably exceed contamination for some elements, because the results differed in some respects from those obtained for citrus.^ Statisticaly significant differences were not obtained for other elements analyzed.^ Even though 40 to 57 percent of the iron, aluminum, silicon, and titanium was washed from the leaves, cluster analyses grouped the four elements into a common cluster whether or not the leaves had been washed.^ Washing resulted in a lower coefficient of variation for some of the elements compared with unwashed leaves. |
