Abstract

A greenhouse pot experiment was conducted to evaluate the phytotoxic effect of heavy metals (Zn, Cu, Ni, and Cr) on the growth (plant height, plant and seed weight) of Coriandrum sativum and uptake of metals. For this purpose, the polluted soil and sludge samples were collected from three sites of Moradabad: Karula nala (KS), Dhauri nala (DS), and Karula nala sludge (KSL). Metal content in the plant and soil was determined by AAS technique. The plants were also hydrodistilled using Clevenger apparatus and the extracted oil was analyzed by GC and GC/MS. The content of copper in KS and KSL, Zn in KS, Ni in DS and KSL, and Cr in KS was above the permissible limits according to Indian standards. Plant weight was significantly affected in the different soil samples. Among all the collected polluted soil and sludge samples, DS sample showed the highest metal accumulation, while in the KSL sample, the plant could not survive. The study revealed that coriander can be used to remediate the contaminated soil with economic return and metal free final product, essential oil.
