Vegetables provide the human body with the essential bioavailable trace elements, and a constant supply of these various elements is necessary and highly recommended for daily life. Minor elements such as Fe as well as trace elements such as Cd, Co, Cr, Cu, Mn, Ni, and Zn were determined using an atomic absorption spectrophotometer in 8 different species of vegetables from the local markets in and around the city of Shillong, Meghalaya, India. The different vegetables were Diplazium esculentum (Fern), Curcuma longa (Tumeric), Beta Vulgaris (Beet), Zingiber officinale (Ginger), Oenanthe javanica, Houttuynia cordata, Mentha asiatica (asian mint), Coriandrum sativum (Coriandar), Spinacia oleracea (Spinach) and Lactuca sativa (Lettuce). The results reveal that the different element concentrations of each vegetable depend upon the selective uptake of the elements by the plant. The element concentrations of these vegetables were within safety baseline levels for human consumption.
