Determination of some minerals and heavy metal levels in Urfa cheese and cow's milk

Abstract

This research was carried out to determine the levels of some minerals and heavy metals in Urfa cheeses and cow's milk offered for sale in Şanlıurfa. Mineral and heavy metal levels were determined by analysing 18 Urfa cheese and 21 cow milk samples collected from retail outlets with ICP-MS. Mean mineral and heavy metal contents in Urfa cheese samples were; magnesium (Mg) 129.8 ±31.14 mg/kg, calcium (Ca) 2712.66 ±1002.4 mg/kg, potassium (K) 272.06 ±127.21 mg/kg, titanium (Ti) 7.48 ±2.63 mg/kg, zinc (Zn) 40.4 ±16.33 mg/kg, selenium (Se) 10.6 ±3.51 mg/kg. In cow milk samples, average selenium (Se) 0.22 ±0.04 mg/kg, titanium (Ti) 0.07 ±0.009, mg/kg, copper (Cu) 0.0068 ±0.01 mg/kg and chromium (Cr) was detected at the level of 0.019 ±0.001 mg/kg. Arsenic (As), cadmium (Cd), lead (Pb) and thallium (Tl) levels were below the detectable levels in Urfa cheese and cow's milk samples. As a result, it was concluded that the samples do not pose a significant danger to public health in terms of heavy metal pollution and can contribute significantly to nutrition with the mineral substances it contains.

“…For this reason, the determination of the heavy metal level in cheeses is very important [ 24 ]. As for the heavy metal concentration in this study, their content was very low, comparable to values reported in the literature [ 24 , 25 , 26 , 27 ]. Lead was below the permissible levels.…”

“…In the present study, low levels of cadmium, below 0.008 ppm, were detected. This is, nevertheless, important due to the high toxicity presented by cadmium [ 26 ]. Our study demonstrated a concentration of cadmium similar to the level obtained by Al Sidawi et al The most often indicated source of cheese contamination with toxic metals by these authors is residues of these metals in animal fodder and in water [ 24 ].…”

“…Generally, heavy metal contamination is infected from environmental sources such as soil and water or feed consumed by animals. In addition, metals in the composition of machinery and equipment used during milk storage and processing may leach into the product during milking [6].…”
