Sažetak

A modern and intensive cattle breeding involves the use of good quality food, which has to be in accordance with the basic nutritional requirements and health standards to protect human health. Corn is one of the most important components of fodder mixtures and it is subjected to drying in kilns of different designs. The kilns use various energy sources and it is possible to contaminate corn grain with carcinogenic PAHs generated by fuel combustion. The aim of this study is to determine the presence of carcinogenic PAHs on the grain after drying in a direct-fired kiln plant in case when light oil and ground gas were used. The research results point to a regular presence of carcinogenic PAHs in case when both types of fuel were used, but their values are not significant in terms of the adsorbed amount and therefore they cause no significant risk. Ground gas has a considerably more favourable energy efficiency level compared to light oil.
