In this study, 144 raw milk samples were analysed for heavy metal contamination derived from emissions from industrial operations in Tekkekoy, Samsun, Turkey. Cu, Fe, Zn, Cr, Ni, Cd, As and Pb levels in samples were determined by inductively coupled plasma mass spectrometry (ICP‐MS). The average amounts of copper, chromium, iron, zinc, nickel, cadmium, arsenic and lead were determined as 1.130, 0.441, 12.920, 0.032, 0.483, 0.006, 0.003 and 0.004 mg/kg, respectively. It was determined that the summer period has the highest levels for copper, lead and cadmium. The highest contents of arsenic and copper were found at the two industrial regions that were close to Black Sea, described as ‘1st’ and ‘2nd’ region. Whereas the 3rd and 4th regions that were far from an industrial zone and also from the Black Sea, nickel, lead and chromium had the highest levels.
