原始语种摘要: Usually farmer irrigates crop by heavy metal polluted river water due to shortage of water in dry season in Dhaka. This polluted water mainly enters to rivers as an industrial waste. The aim of the study is to assess the extent of heavy metals accumulation in soil and crops due to irrigation with industry-fed polluted river water on agricultural land. Samples of water, river bed soil and crops have collected in dry season from Bongshi River in Dhaka, Bangladesh. The collected samples have been analyzed for seven heavy metals namely Cr, Cd, Pb, Ni, Cu, Fe, and Zn using Atomic Absorption Spectrophotometry (AAS) in the laboratory. The results showed that considerable amount of these heavy metals have been found in tomato, pumpkin and red amaranth indicating heavy metals exists in our food...
