anglais. The content of Ag, Al, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Na, Ni, Pb, Rb, Sn, Sr, V and Zn in 60 wines from Trentino was determined by Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES). Red wines had significantly higher levels of B, Ba, Fe, K, Li, Mg, Ni, Pb, Rb and Sr than white wines. Calcium was higher in white wines. The low amounts of Ca, Mg, Fe, Pb and Zn testify to the improvement in winery equipment in the last decades. Copper was at times in excess of technological needs, probably due to residues from spray treatments of the grapes

I contenuti di Ag, Al, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Na, Ni, Pb, Rb, Sn, Sr, V e Zn di 60 vini del Trentino sono stati analizzati per ICP- OES (Inductively Coupled Plasma-Optical Emission Spectrometry). I vini rossi avevano contenuti significativamente piu' elevati di B, Ba, Fe, K, Li, Mg, Ni, Pb, Rb e Sr rispetto ai vini bianchi. Il calcio era piu' alto nei vini bianchi. I bassi contenuti di Ca, Mg, Fe, Pb e Zn testimoniano i miglioramenti delle attrezzature di cantina avvenuti negli ultimi decenni. Talvolta il rame, probabile residuo di trattamenti in vigneto, e' risultato in eccesso rispetto alle necessita' tecnologiche
