Podawanie królikom codziennie domięśniowo farmakologicznego preparatu żelaza w ilości 6 mg/kg m.c./dobę doprowadziło po 90 dniach do jego kumulacji w wątrobie, skórze i mięśniach. Stwierdzono, iż wątroba i skóra najintensywniej kumulują żelazo między 3 a 10 dniem, zaś mięśnie w pierwszych trzech dniach eksperymentu.

The experiment was carried out on chinchilla rabbits. The rabbits were given (in the form of injection) "Jectofer" - an iron specimen; the amount of the injected specimen was 6 mg/kg of body mass per day for 3, 10 and 90 days. The amount of iron was determined in mineralised skin samples, in thigh muscle and liver by means of atomic absorption spectroscopy (AAS). It was observed that the time of exposition on iron ions influenced its amounts in the examined organs Conscquently, after 90 days of the experiment it was noted that the amount of iron grew 5 times in liver of the examined animals, 4 times in their skin and less than 2 times in their muscles. It was also noted that the muscles and liver accumulated iron the most intensively between the 3rd and the 10th day of the experiment, and that the skin accumulated iron the most intensively during the first three days. These results prove that excessive supply of iron leads to its accumulation in the organism with different intensity and dynamics for different organs.

We observed, both in the leaves and roots of the vegetables examined, that the concentration of fluoride was in each case higher in vegetable samples in Łosień, 6 km from the “Katowice” Steel Works (fluorine emitters), than in the vegetable samples grown in Nowy Sącz, 200 km from the “Katowice” Steel Works (in the area of relatively low fluorine pollution). The highest F content was characteristic of beet (Beta vulgaris) leaves and root samples, the lower one was found in celery (Apium graveolens) leaves and root samples and the lowest one in savoy (Brassica oleracea) leaf samples. The highest and lowest F- concentrations in the leaf samples examined was c.a. 33 mg/kg D.W. (beet leaves from Łosień of 1995) and c.a. 11 mg/kg D.W. (savoy leaves from Nowy Sącz of 1996). Moreover, it was found that the observed growth of F- concentration in the savoy leaf samples, both from Łosień and Nowy Sącz, correlated with an increase of nitrogen concentration in them.

Bee pollen belongs to bee products that are characterized by high nutritional value and biotic activity. These characteristics result from the wide variety of compounds that bee pollen contains. Our study determined the effects of storage conditions of bee pollen extracts on polyphenol content. The study was conducted with the use of three types of bee pollen extracts, namely ethanol extracts, enzymatic hydrolysates from pollen, and ethanol extract of pepsin-digested bee pollen. Polyphenol content in the studied extracts was determined immediately after extraction and after 12-month storage. We have concluded that 12- month storage of bee pollen extracts decreases polyphenol concentration in all three types of extracts, and the changes depend on the storage conditions.
