Heavy metals analysis (Cd, Pb, Zn, Cu, Cr) and calcium in Padang and Padang Panjang fresh cow’s milk

Abstract Cow’s milk is important in a healthy food intake because of its high calcium content. However, the contamination can be harmful to health. The acidity cow’s decreases with increase heavy metals concentration that poisonous body. This research aims investigate content (Cd, Pb, Zn, Cu, Cr) and minerals Ca contained fresh samples from two different locations, which are Padang city Panjang city. metal these places has never been tested. quantitative method used this Atomic Absorption Spectroscopy (SSA). average Lubuk Minturun area are: cadmium (Cd) not detected, lead (Pb) 13.58±1.01 ppm, zinc (Zn) 28.83±1.81 copper (Cu) 1.17±0.38 chromium (Cr) (Ca) 674.00±2.46 ppm. Meanwhile, area: Pb 20.58±2.02 Zn 53.08±2.40 Cu 2.17±0.38 504.25±2.63 All both regions showed exceeded maximum limit set by Environmental Protection Agency (EPA), consequently it could cause negative impacts on health when consumed. assumed caused cattle garbage pesticides requires further research.
