New Delhi: Dangerous level of metals have been found in vegetables grown in fields along the River Yamuna which could cause life threatening diseases like cancer, a study has found. According to the study conducted by the National Environmental Engineering Research Institute (NEERI), samples from three east Delhi locations were collected to check status of metal concentration in seven vegetables -cabbage, cauliflower, radish, brinjal, coriander, fenugreek and spinach.

The report found the maximum lead contamination in coriander collected from Geeta Colony. The safe limit for lead in vegetables is 2.5mg/kg as per the Food Safety and Standards Authority of India (FSSAI). The level of the metal detected in samples collected from the floodplain ranges from 2.8mg/kg to 13.8mg/kg, it said, adding heavy metal toxicity can damage organs. “Prolonged human consumption of unsafe concentrations of heavy metals in foodstuffs may lead to disruption of numerous biological and biochemical processes in the human body.

They can also damage the blood composition and other important organs. Long term exposure of metals may even cause cancer,” the study, conducted by NEERI on the directions of NGT, said. The report said that other metals –cadmium, mercury and nickel were found below the FSSAI standards. “In the present study, only levels of lead were found exceeding the FSSAI limits in most of vegetable samples, therefore, there is need for further investigation on the sources, from where Pb is getting accumulated in the vegetables, though corresponding soil samples also exhibited high levels of lead.
