ABSTRACT

A randomized poly house pot experiment was conducted in three replicates to examine the accumulation of heavy metals (Zn, Cu, Ni and Cr) with the application of different amendments of manure (cow dung) (0t/h, 26t/h, 52t/h and 104t/h) along with the effect on the essential oil composition and the growth of Coriandrum sativum in contaminated soil samples. The contaminated soil sample was collected from industrial area of city Moradabad (Karula nala). The treated plants were harvested 90 days after sowing. Growth parameters such as plant height, weight and seed weight were also recorded. Metal content in plant and soil samples was analyzed by AAS. The plant material was also hydrodistilled using Clevenger apparatus and analyzed by GC and GC-MS to evaluate the effect of manure addition on the different constituents of the essential oil. The growth of C. sativum was found to be the best in two manure amendments (52 and 104t/h). In manure-amended soil, the accumulation of all metals by this plant decreased regularly. Linalool content was observed to the highest in 52t/h manure amendment without accumulation of metal in oil. Therefore, C. sativum can be grown in manure-amended contaminated soil samples as an alternative crop, as the final product (essential oil) is free from metal.
