 en Characterization of Heavy Metals in Vegetables Using Inductive Coupled Plasma Analyzer (ICPA)
Nirmal Kumar, J.I.; Soni, Hiren & Kumar, Rita N.

Abstract

The heavy metals or trace elements play an important role in the metabolic pathways during the growth and development of plants, when available in required concentration. The heavy metal concentration of Cadmium (Cd), Cobalt (Co), Copper (Cu), Iron (Fe), Nickel (Ni), Lead (Pb) and Zinc (Zn) was analyzed using Inductive Coupled Plasma Analyzer (ICPA) (Perkin-Elmer ICP Optima 3300 RL, USA) in 21 vegetables collected from Vegetable Market of Anand town, Gujarat. The vegetables are Lady’s Finger ( Abelmoschus esculentus check for this species in other resources ), Onion ( Alium sepa check for this species in other resources ), Cauliflower ( Brassica oleracea var. botrytis check for this species in other resources ), Beat ( Brassica oleracea check for this species in other resources ), Chilli ( Capsicum annum check for this species in other resources ), Tindora ( Coccinia indica check for this species in other resources ), Pattarveli ( Colocasia check for this species in other resources sp.), Coriander ( Coriandrum sativum check for this species in other resources ), Cucumber ( Cucumis sativus check for this species in other resources ), Turmeric ( Curcuma longa check for this species in other resources ), Vetches/Gavar ( Cyamopsis soralioides check for this species in other resources ), Bean Pods ( Dolichos lablab check for this species in other resources ), Carrot ( Ductus carrotus check for this species in other resources ), Ginger ( Gingiber officinalis check for this species in other resources ), Sweet Potato ( Ipomoea batatas check for this species in other resources ), Bottle Gourd ( Lagernaria vulgaris check for this species in other resources ), Tomato ( Lycopersicum esculentum check for this species in other resources ), Bitter Gourd ( Momordica charantia check for this species in other resources ), Drumstick ( Moringa oleifera check for this species in other resources ), Brinjal ( Solanum melongena check for this species in other resources ) and Parwar ( Trichosanthes dioicea check for this species in other resources ). The high concentration of Cd was found in Onion, Coriander and Cauliflower, while Co and Cu content was recorded high in Cauliflower and Bottle Gourd. On the other hand, high content of Fe was observed in Cauliflower and Cucumber. Vetches and Lady’s Finger had shown high concentration of Ni. Cauliflower and Onion showed high amount of Pb. On the other hand, Cucumber and Cauliflower registered maximum content of Zn. The heavy metal concentration in vegetables was within the prescribed safety limits except Fe owing to iron-rich soil of the area. The distribution and characterization of heavy metals in vegetables was studied in detail and discussed in this paper.
