Exposure of Rhizopogon roseolus mycelia to 15 mmol·dm⁻³ cadmium for 24 h induces a different pattern of Mn-SOD on polyacrylamide gels, probably being a changed form of an originally existing one. The presence of cadmium affects the chromatographic properties of this enzyme and its mobility through the acrylamide gel. This new isoform was purified using DEAE Trisacryl chromatography. Cadmium induced isoform adsorbed stronger to the ligands and was eluated with a Tris-HCl buffer containing 0.1 mol·dm⁻³ NaCl. SOD from control samples (not treated with cadmium) was eluated with the same buffer without NaCl.

Cadmium was determined in the soil of six allotment gardens of Lodz, situated in areas with different traffic patters (the centre of the city and its suburbs). It was determined in the form of cadmium (II) dithizonate by the extraction-spectrophotometric method.

The toxic action of cadmium in the bone tissue is known, but its mechanisms are still unexplained. We examined whether Cd influences collagen content and its solubility in the femoral bone of three-week-old female rats exposed to 5 or 50 mg Cd/l in drinking water. Non-cross linked collagen was extracted with 0.5 M acetic acid, and two acid-insoluble collagen fractions were extracted with pepsin and 4.0 M guanidine hydrochloride, respectively. SDS/PAGE showed the presence of two collagen types, I and V, in all three extracted fractions. Exposure of rats to Cd for 6 months increased the amount of acid-soluble collagens type I and V and decreased the level of acid-insoluble collagens. The amount of total collagen extracted from the bones of rats exposed to 50 mg Cd/l was reduced by about 14% as compared to control and those intoxicated with 5 mg Cd/l. The solubility of type I bone collagen (determined as the percentage of acetic-soluble fraction of total collagen) was increased 2.9- and 3.0-fold in rats intoxicated with 5 and 50 mg Cd/l, respectively. Similarly, the solubility of type V collagen was increased 2.3- and 2.7-fold, respectively. Our results indicate that Cd treatment affects bone collagen by decreasing its content and increasing its solubility.

Cadmium is an environmental pollulant highly toxic to all forms of life. In this paper we studied by polarography the effect of the environment on cadmium speciation and also the effect of this speciation on 109Cd uptake and toxicity to living cells of cadmium-sensitive Staphylococcus aureus 17810S in different media. It was found that the magnitude of passive ,09Cd adsorption was proportional to the content of free Cd2+ in the medium (cadmium speciation). In contrast, the magnitude of energy-requiring l09Cd accumulation did not depend on cadmium speciation and was similar in all media. This could be due to the higher affinity of Cd2+ to the Mn2+ transport system than to the complexing ligands in the medium. Thus, cadmium uptake by S. aureus 17810S depends both on environmental and cellular factors and under all circumstances results in strong toxicity to living cells.

Cadmium levels in cord blood (CdB) of 40 neonates living in the town of Chorzów (Upper Silesia) have been determined. The mean CdB concentration was 0.439 μg/dl (SD=0.185). Smoking before and during pregnancy raised CdB levels in newborns. Mean Cd concentration in the neonates born to smoking mothers was 0.504 versus 0.353 μg/dl in those of woman who did not smoke during pregnancy.

Comparative tests on the sensitivity of actinomycetes to cadmium and copper ions were carried out on 19 wild strains of the genus Streptomyces. The strains were tested by placing solutions of cadmium chloride on filter paper disks in quantities of 20 and 40 μg Cd2+, and also 20, 40 and 80 μg Cu2+ converted to metal. Both conidial and vegetative forms of actinomycetes were used as inoculum. Differentiation was found in the reactions of the actinomycetes on the tested metals depending on the nutrient used, especially on nitrogen sources. Copper ions have a greater effect on the vegetative forms of these organisms than cadmium ions, while cadmium ions exert an inhibiting effect on the process of conidia germination.
