Abstract


Introduction: Iodine concentration was studied in Polish consumer milk.
Material and methods: The milk originated from 13 provincial cities and 65 dairy cooperatives located in Poland.
Results: Milk iodine concentration in the winter season of 2007-2008 was 146.8 mg/L, with a standard deviation for the provinces of 27.9 mg/L and variation coefficient of 19.0% (n = 66 samples). Iodine concentration for provincial cities ranged from 76.3 to 192.0 mg/L. It was highest in the milk samples from the Lubelskie province (191.9 mg/L) and lowest in the milk samples from Podlasie (113.8 mg/L). In the summer season, milk iodine concentration averaged 100.4 mg/L, with a standard deviation of 38.9 ìg/L and variation coefficient of 38.8% (n = 27 samples).
Conclusions: Iodine concentration for provincial cities ranged from 63.8 to 173.7 mg/L. Compared to the winter season, milk iodine concentration in the summer season was lower by an average of 25.2%, with a standard deviation of 4.3% (Kielce) to 52.2% (Wrocław).
