In this study, amounts of chromium (Cr), cobalt (Co), nickel (Ni), copper (Cu), cadmium (Cd), lead (Pb), aluminum (Al), 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 the 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 analyzed. Levels of metals in the samples are determined with the ICP-MS method. It is found that the
amounts of lead and aluminum in cow’s milk in winter and summer season are close to each other while the amounts of chromium, cobalt, zinc,
nickel, copper, iron, and cadmium are a bit more in the winter season. The amounts of metal in the analyzed kinds of milk are found to be between
or under the specified rates given in literature except for nickel in milk from all 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.
