Dietary intake of contaminated crops with
heavy metals causes serious human health risks. The
current study focused on the atomic absorption analysis
of Zn, Cu, Co, Pb, Mn, Fe, Cd, and Cr in the
wheat grains and soil using pot experiment conducted
in Sargodha, Pakistan. Results showed that
the Zn concentration in wheat grains increased with
continuous wastewater utilization. Except cadmium,
mean concentration of other heavy metals was
within permissible limits in the soil. A significant
and positive correlation was also observed for Cu,
Pb, and Cr between soil and crop. The application of
wastewater for longer period of time caused enrichment
factor and health risk index to be increased considerably
suggesting that proper management is required
for treating domestic wastewater to prevent
potential health risks via dietary intake of crops contaminated
with heavy metals.
