Abstract
Ninety seven samples of nine different
fruits were collected from various agriculture farms of
Winder area, cultivated over igneous rocks of Bela
Ophiolite (Cretaceous) and sedimentary rocks of
Jurassic age (Ferozabad Group).In the present study
Principal Component Analysis(PCA) has been
employed to discriminate possible sources that
influence trace element distribution in different fruits.It
(PCA) revealed contribution of Mn and Ni from
different segments of Bela Ophiolite, while the source of
Zn and Cu is linked with MVT and Sedex-type
mineralization present in the area. Cluster Analysis
(CA) of different fruits organized sampling sites into
two or three statistically significant groups mainly on
the basis of Fe, Co, Cu and Zn concentration.
Trace elements content showed wide variation in
concentration with respect to sample sites and fruit type
in the study area. The fruits of M. zapota (Chikoo)
showed higher concentration of Fe (14mg/kg) among
the other trace elements. The trace element assemblage
of mango (M. indica) shows wide spread but at low
magnitude. Iron (3.3mg/kg), Cr (2.6mg/kg), Zn
(1.8mg/kg) and Cu (1.6mg/kg) are the main
contributors. Comparatively, fruits of some locations
have shown highest intake of trace elements relatively
daily recommended.
