Chemical analyzes of the rings of Valtellina larches have reported information on the absorption of metallic elements by the plants.

Abstract
Chemical analyzes of the rings of Valtellina larches have reported information on the absorption of metallic elements by the plants. In part these enrichments could be linked to the absorption of nutrient elements in the sapwood part (approximately the last 50 years), but for some elements such as Pb the enrichment begins in rings of over a hundred years and does not seem linked to physiological aspects, but is rather due to anthropogenic pollution.File | Dimensione | Formato | |
