Abstract

Nitrite and nitrate contents of 24 fresh vegetables and herbs available from retail markets in southern India were investigated. Samples tested included 9 leafy, 7 root/tuber and 8 other types of vegetable. Nitrate contents of leafy vegetables ranged from 528 ppm in mint to 3124 ppm in shepu (Peucedanum graveolens). In root/tuber vegetables, nitrate contents were lowest in carrot (138 ppm) and highest in beetroot (2915 ppm). Of the other vegetables tested, nitrate levels were in the range 68-1659 ppm, with min. and max. values being observed for pumpkin and knol-khol (Brassica oleraceae), respectively. Nitrites were either not detected or were present at much lower concn. than those of nitrates, with highest amounts being found in some samples of shepu (2.43 ppm).
