Abstract
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.
