Determination of Some Metal Contents of Cow’s Milk in Akçabaat District of Trabzon through the ICP-MS Method

Abstract

In this study, amounts of chrome (Cr), cobalt (Co), nickel (Ni), copper (Cu), gallium (Ga), cadmium (Cd), lead (Pb), aluminium (Al), silver (Ag), iron (Fe), and zinc (Zn), are indicated in cow's milk provided from sixteen different villages (Aykut, Helvacı, Erikli, Düzköy, Akçakale, Demirkapı, Acısu, Yaylacık, Çiçeklidüz, Esentepe, Arpacılı, Işıklar, Adacık, Osmanbaba, Yeşiltepe, Mersin) in Akçaabat district of Trabzon. The study was done in two different terms of year. The first term is the winter season (November, December and, January named as Term I), during which animals are fed with dry fodder in the barn. The second term is the summer season (June, July, and August named as Term II), during which animals are fed with fresh feed. A total of 256 samples are analysed. Levels of metals in the samples are specified with the ICP-MS method. It is found that the amounts of gallium, lead, and aluminium in cow’s milk in winter and summer season are close to each other while the amounts of chrome, cobalt, zinc, nickel, copper, iron, and cadmium are a bit more in the winter season. The amounts of metal in the analysed kinds of milk are found between or under the specified rates given in literature except for nickel in milk from all villages, silver in four villages, and lead in one village. The amounts of mineral matter in milk in all villages are found under the rates given in the literature.
