Heavy metals pose risk to human health. The present study was carried out to
assess levels of different heavy metals like lead, Copper, Chromium, Nickel and
Iron, in celery irrigated with water from different sources. The results indicated a
substantial build-up of heavy metals in vegetable irrigated with wastewater. The
range of various metals in surface water mixed with wastewater-irrigated plants
was 0.0005, 0.0003, 0.0086, 0.0006, 0.2106 mg/L for Pb, Cu, Cr, Ni and Fe
respectively, in sarchnar location, and lowest value of these metals was determined
in well water used for irrigation in kalar location and values are (0.0002, 0.0014,
0.0171, 0.0004 and 0.0020 mg/L) for Pb, Cu, Cr , Ni and Fe respectively. The
highest levels of Fe detected in celery value 5.181and 3.983 mg/kg in Sarchnar and
Kalar location, respectively. The present study highlights that both adults and
children consuming vegetables grown in wastewater-irrigated soils ingest
significant amount of these metals. However, the values of these metals were below
the recommended maximum tolerable levels. The regular monitoring of levels of
these metals from effluents and sewage, in vegetables and in other food materials is
essential to prevent excessive build-up of these metals in the food chain.
