Zawartości Ca, Mg, Fe i Cd w dwóch rodzajach miodu, nektarowym i spadziowym, pochodzących z terenów niezurbanizowanych i zurbanizowanych były mało zróżnicowane. Jedynie ilości Cd w miodach z terenów miejskich wskazują na wpływ zanieczyszczenia środowiska.

Contents of Ca, Mg, and Fe in two types of honeys, nectarous and honeydew, collected from non- urbanized and urbanized areas were investigated. Also the Cd content, as a marker of the environmental contamination was determined. The Ca concentration of was higher in nectarous honeys than in honeydew, whereas a higher content of Mg was in honeydew honey. This difference concerned both kinds of honeys from non- urbanized areas as well as honeys from urbanized areas. The Fe content in honeys varied depending on the regions. In non-urbanized areas a higher content of Fe was in nectarous honeys, and from urbanized areas - in honeydew honeys. The level of Cd was significantly higher in honeydew honeys than in nectarous, and also significantly higher in both kinds of honeys from urbanized areas. Greater pollution of the environment in urbanized areas did not have significant influence on the Ca, Mg and Fe contents, but did affect the content of Cd.

Our study examined changes in the red blood system of rats under the influence of aluminium chloride administered in a physiological way with drinking water in the following doses : 0.5 g/l, 1 g/l and 2 g/l. The significant decrease of erythrocyte numbers, haemoglobin levels and haematocrit values which accompanied the highly significant statistical elevation in reticulocyte contents were observed in intoxicated animals. Also, the decrease of mean cell volume (MCV), average diameter of erythrocyte (D) and its surface area (S) were noted. Respiratory surface of blood volume unit (Sresp.) and coefficient F in group received AlCl3 at doses of 0.5 g/l were slightly higher then in control group. Groups that received 1 g/l and 2 g/l decreased in Sresp. and coeficcient F. Our data showed that aluminium intoxication impairs respiratory function of the blood.
