The study was aimed at determining the impact of the milk production period and selected dairy products on the level of external chemical compound residues in milk. For this reason the experimental material was sampled in the summer and in winter season. A total of 120 dairy products were assayed for the concentrations of lead, cadmium, Σ DDT (as a total sum of DDT+DDE+DDD), γ HCH, total PCB, nitrates...
The preferences and frequency of consumption of milk and its products were evaluated among school children together with determining the significance of factors affecting the choice of the products. The studies were carried out among 1498 school children (820 girls and 678 boys aged 15 to 19 years) from selected regions of northern, central and eastern Poland. The preferences were determined for 13...
