Assessment of Lead and Cadmium Status in Feedstuffs, Milk and Water Samples in Haryana State of India
Vol 9(2), 129-137
A survey of feedstuffs, milk and water samples (n=742) from Haryana state of India was conducted by dividing the State in three zones on geographical and agro-climatic basis. Districts of Sirsa, Fatehabad and Hisar were in Zone 1, Rohtak, Bhiwani, Mahendra Garh, Rewari, Jhajjar, Faridabad and Gurgaon in Zone 2 and Ambala, Kurukshetra, Yamuna Nagar, Karnal, Kurukshetra, Panipat, Sonipat, Jind and Kaithal in Zone 3. A significantly higher content of Pb in cereals and green fodder in Zone 2 and green fodder in Zone 3 was observed. The mean Cd content was significantly higher (P < 0.05) in oil cakes and dry fodders in Zone 1 and 3, respectively. Milk Pb contents were in range of 0.14 to 0.39 mg kg-1. Per cent transfer factor of Pb from feed to milk ranged from 7.21 to 36.84 in the order of Zone 2>Zone 3>Zone 1. Cd contents of milk in Zone 1, 2 and 3 averaged 0.0127, 0.0140 and 0.0234 µg mL-1, respectively. Transfer factor of Cd from feed to milk was in range of 9.27 to 20.38 with maximum rate in Zone 2, followed by Zone 3 and Zone 1. Water samples analyzed for Pb and Cd content were within the maximum permissible limits for livestock.
