Evaluation of heavy metal concentration in the poultry feeds
Abstract
The study was conducted in order to determine the heavy metals contamination in poultry feed. Twenty-one samples of poultry feed were collected from three feed companies and five poultry farms. The samples were analyzed via Inductively Coupled Plasma- Spectrophotometer for heavy metals; arsenic, cadmium, copper, chromium, mercury, iron, lead, manganese, nickel and zinc. All the samples were collected from Kasur as it is the hub of tanning operations in Punjab and environmental pollution being generated from the tanneries is quite rampant. The effluent from the tanneries is discharged into the drains without any treatment. Results showed the presence of heavy metals in all the analysed samples. However, none of the metals, except for mercury, were present at alarming levels. Mercury exceeded the tolerable limits set by both European Union and National Research Council in all the samples.
