Resum
The “Gauss Peak Spectrum” mathematical method was studied and optimized in our laboratory.This work shows the protocol followed for the operation of a method we consider importantin assesssing the effect of heavy metals in vascular herbaceous species.Results are shown for four pasture grasses, which grow on the site of abandoned silver minein Toledo province. In this enclave grasses are the species with most pastoral value for livestocknutrition as well as for the abundant wildlife (the site is a hunting ground). The topsoil layer hasvery high levels of Pb and Zn, and Cd and Cu are above acceptable reference levels for soil inseveral places. The method allows quantification of chlorophylls affected by Cu, Zn and Cd in theanalyzed species (Agrostis castellana, Arrhenatherum bulbosum, Dactylis glomerata, Micropyrumgenellum). Chlorophyll-a is mostly affected by Cu, even though Zn is the metal most accumulatedin these species.
