Abstract: 

This investigation was carried out to determine the accumulation of the heavy metals in the cabbage grown in Industrial Estate (IE) effluent irrigated soil in the different villages of district Haridwar (Uttarakhand), India. The results revealed that wastewater discharged from IE was highly rich in plant nutrients and heavy metals. The wastewater irrigation significantly (P<0.05/P<0.01/P<0.001) increased the contents of heavy metals in the soil and cabbage grown in wastewater irrigated soil. Agronomical performance of Cabbage is increased due to irrigation with IE effluent. Among the all heavy metals the maximum accumulation of Fe, Cd and Cu were recorded in edible part of cabbage. The translocation of various metals were recorded in the order of Mn >Zn > Cr > Fe>Cu > Cd in the cabbage. Although, the contents of Cd and Cr cabbage were recorded above the prescribed limit of WHO/FAO standards and remaining metals are continuously increasing as per number of effluent irrigation. Therefore, regular monitoring of effluent irrigated cabbage must be required to prevent possible hazards caused due to the consumption of heavy metals contaminated vegetables.
