Efficacy of Transfer of Heavy Metals in Wheat Grown in Municipal Solid Waste Amended Soil

Document Type : Original Article

Abstract

Municipal solid waste was considered to contain a variety of toxic metals. The heavy metals accumulate in plants due to extensive use of municipal wastes in crops. The current study was conducted to demonstrate the influence of municipal solid waste treatments on the metal content of soil and wheat crop. In this direction, the seeds of wheat variety (Galaxy-13) were sown and four heavy metals Cd, Fe, Zn, and Co in grown plants were analysed by using Atomic Absorption Spectrophotometer. The level of metals (mg/kg) in wheat grains varied from 1.36 to 1.76, 9.7 to 21.2, 0.6 to 0.9 and 0.58 to 0.72 for Cd, Fe, Zn and Co, respectively. Pollution indices were used to determine pollution and accumulation levels. It was observed that bio concentration factor; pollution load index and enrichment factor values of Cd were high. Finally, it can be said that municipal solid waste must be treated properly before its application on agricultural land to avoid the excessive build-up of heavy metals in the food chain.
