Abstract
This study aimed to determine the concentrations of lead (Pb), cadmium
(Cd), and chromium (Cr) in commercial pet foods available in Raipur,
Chhattisgarh, using Atomic Absorption Spectroscopy (AAS) after a wet digestion
method. The analytical data revealed that all three investigated heavy metals
were detected in each commercial dry pet food sample. Lead concentrations
ranged from 0.12-0.17 mg/kg, cadmium 0.010-0.016 mg/kg, and chromium
0.593-0.679 mg/kg. Among the analyzed samples, dog food contained the highest
concentrations of lead (0.17 mg/kg) and cadmium (0.016 mg/kg), whereas cat food
exhibited the highest chromium concentration (0.679 mg/kg). Fish food contained
intermediate concentrations of lead and chromium but the lowest cadmium
concentration. Levels of lead and cadmium measured in pet food were well below
international safety limits. Lead was less than 2% of the maximum limit, and
cadmium was just 1.6% of the limit. There is no set limit for chromium, but the
levels found in this study were within the range of typical scientific reports
and did not indicate any serious contamination.
