Free-radical scavenging capacity evaluated by ABTS and DPPH assays and expressed as EC50 (mg/L, with 95% confidence limits in brackets) of tomato extracts of Pomodoro Giallo grown in uncontaminated (NC) and contaminated (Cd, Cr, Pb) soils. A significant difference from NC was determined with Unpaired t-test*p<0.05, **p<0.01.
