Assessment of metals in vegetables irrigated with biomethnated textile effluent at Haridwar (Uttarakhand), India

The present study showed that irrigation of soil with biomethnated textile effluent (BMTE) resulted in significant (P<0.01) changes in chlorides (Cl-), organic carbon (OC), sodium (Na+), potassium (K+), calcium (Ca2+), magnesium (Mg2+), total Kjeldahl nitrogen (TKN), phosphate (PO4 3-), sulphate (SO4 2-), iron (Fe), zinc (Zn), cadmium (Cd), copper (Cu), chromium (Cr), nickel (Ni) and cobalt (Co) of the soil. The significant (P<0.05) accumulation of metals viz. Fe, Zn, Cd, Cu, Cr, Co, and Ni were also recorded in the different parts (shoot, root, leaves, and fruit) of P. vulgaris, V. radiata, V. faba and L. usitatissimum crops after irrigation with BMTE in comparison to bore well water (BWW). The maximum content of metals was observed in the root of P. vulgaris, shoot of V. radiata, fruit of V. faba and leaves of L. usitatissimum after irrigation with BMTE. The contamination factor was observed to be crop specific. The maximum contamination factor was found of Ni for P. vulgaris, Co for V. radiata and L. usitatissimum and Cr for V. faba after irrigation with BMTE.
