In 2002, assays were performed on 24 immature (imm) and 66 adult (ad) individuals. In 2003, 15 immature birds could be assayed, while the 2004 sample consisted of a total of 71 individuals (12 imm and 59 ad). Pigeons were caught near the villages of Skarbimierzyce and Dołuje situated west of Szczecin. Fluorine and calcium content in ash and dry mass of the wood pigeon's tarsometatarsus bones was determined. Fluorine content in ash and dry mass increased with age of the bird. It was only in 2002 samples that significant differences between immature and adult pigeons in calcium ash content were detected. Analysis of variance (ANOVA) failed to reveal significant differences between 2002 and 2004 samples in calcium content of adult bone ash. The remaining parameters in this group of birds differed significantly. The immature group showed no significant differences between 2002 and 2004 samples in fluorine content of bone ash and dry mass. Significant differences (p < 0.01) in fluorine content were revealed between 2002 and 2003 as well as between 2003 and 2004 samples. Ash calcium content showed no differences for immature birds of 2002 and 2003; however, significant differences (p < 0.001) were revealed between 2002 and 2004 as well as between 2003 and 2004. No significant differences were revealed between the immature bone dry mass calcium contents in 2002 and 2003 as well as in 2002 and 2004; on the other hand, the difference between the 2003 and 2004 data proved significant (p < 0.05). The present study demonstrated a number of differences in fluorine and calcium content in bones of the plant-eating wood pigeon. In addition, fluorine was found to undergo an intense age-related accumulation in bones. Fluorine content showed marked year-to-year variability. It is highly probable that fluorine content in wood pigeon bone reflects environmental fluorine contamination from industrial plants in Szczecin and its environs which are the major source of fluorine emissions.

The gender-specific analysis of chemical element levels in the bone samples revealed that there were statistically significant differences in the concentration of Pb and Se/Pb ratio. The contents of elements in the tibial plateau in the patients with osteoarthritis (OA) can be arranged in the following descending order: F(-) > K > Zn > Fe > Sr > Pb > Mn > Se > Cd > THg. We observed statistical significant effects of environmental factors including smoking, seafood diet, and geographical distribution on the levels of the elements in tibial bone. Significant positive correlation coefficients were found for the relationships K-Cd, Zn-Sr, Zn-F(-), THg-Pb, Pb-Cd, Se-Se/Pb, Se-Se/Cd, Se/Pb-Se/Cd, Pb-Cd/Ca, Cd-Cd/Ca, and F(-)-F(-)/Ca·1000. Significant negative correlations were found for the relationships THg-Se/Pb, Pb-Se/Pb, Cd-Se/Pb, K-Se/Cd, Pb-Se/Cd, Cd-Se/Cd, THg-Se/THg, Pb-Se/THg, Se-Pb/Cd, Zn-Cd/Ca, and Se/Cd-Cd/Ca. The results reported here may provide a basis for establishing reference values for the tibial plateau in patients with OA who had undergone knee replacement surgery. The concentrations of elements in the bone with OA were determined by age, presence of implants, smoking, fish and seafood diet, and sport activity.

Concentrations of Pb and Cd were determined in selected parts of the femur head of 30 patients after total hip arthroplasty, using ICP-AES (atomic absorption spectrophotometry). Pb contained the highest concentration in cortical bone, while Cd did so in cancellous bone. There were statistically significant differences in the concentrations of both elements between the cartilage and cortical bone, and also differences in the concentration of Pb between the cartilage and cancellous bone. There were no significant differences in the concentrations of Pb or Cd between cortical and cancellous bone. Comparative studies on toxic metals should take into account both analogous bones and their fragments, as even if they come from the same kind of bones (e.g. femur head), clear differences...

The analysis also included the relationship between Hg concentration and the fox size, and the suitability of individual organs as bioindicators in indirect evaluation of environmental mercury contamination. Determination of Hg concentration was performed by atomic absorption spectroscopy. In the analysed samples, the Hg concentration was low and the maximum value did not exceed 0.85 mgHg/kg dry weight (dw). There were no significant differences in Hg concentrations in the analysed material between males and females or between immature and adult groups. The median concentrations of Hg in the liver, kidney and skeletal muscle were 0.22, 0.11 and 0.05 mgHg/kg dw, respectively. The correlation coefficients were significant between...

It eats fish and small invertebrates. The purpose of this study was a preliminary parasitological examination of the digestive tract of the goosander wintering on the Szczecin Lagoon. The research material were the parasites recovered from digestive tracts of 6 birds (two males and four females), which died during feeding in fishing nets in winter 2001. The birds were subject to standard parasitological examinations using commonly adopted methods. The trematodes and the cestodes found were preserved in 70% ethyl alcohol and subsequently stained using iron carmine (Cestoda) and borax alcohol carmine (Digenea) and then they were closed in Canada balsam. Nematodes were kept in 70% alcohol and cleared with 80% lactic acid or lactophenol. The parasite assemblages were analysed through calculating prevalence, intensity of infection, relative density and domination index. Also, the topic structure of t...

Pigeons were caught near the villages of Skarbimierzyce and Dołuje situated west of Szczecin. Fluorine and calcium content in ash and dry mass of the wood pigeon's tarsometatarsus bones was determined. Fluorine content in ash and dry mass increased with age of the bird. It was only in 2002 samples that significant differences between immature and adult pigeons in calcium ash content were detected. Analysis of variance (ANOVA) failed to reveal significant differences between 2002 and 2004 samples in calcium content of adult bone ash. The remaining parameters in this group of birds differed significantly. The immature group showed no significant differences between 2002 and 2004 samples in fluorine content of bone ash and dry mass. Significant differences (p < 0.01) in fluorine content were revealed between 2002 and 2003 as well as between 2003 and 2004 samples. Ash calcium content showed no differences for immature birds of 2002 and 2003; however, significant differences (p < 0.001) were revealed between 2002 and 2004 as well as between 2003 and 2004. No significant differences were revealed between the immature bone dry mass calcium contents in 2002 and 2003 as well as in 2002 and 2004; on the other hand, the difference between the 2003 and 2004 data proved significant (p < 0.05). The present study demonstrated a number of differences in fluorine and calcium content in bones of the plant-eating wood pigeon. In addition, fluorine was found to undergo an intense age-related accumulation in bones. Fluorine content showed marked year-to-year variability. It is highly probable that fluorine content in wood pigeon bone reflects environmental fluorine contamination from industrial plants in Szczecin and its environs which are the major source of fluorine emissions.

The contents of elements in the tibial plateau in the patients with osteoarthritis (OA) can be arranged in the following descending order: F(-) > K > Zn > Fe > Sr > Pb > Mn > Se > Cd > THg. We observed statistical significant effects of environmental factors including smoking, seafood diet, and geographical distribution on the levels of the elements in tibial bone. Significant positive correlation coefficients were found for the relationships K-Cd, Zn-Sr, Zn-F(-), THg-Pb, Pb-Cd, Se-Se/Pb, Se-Se/Cd, Se/Pb-Se/Cd, Pb-Cd/Ca, Cd-Cd/Ca, and F(-)-F(-)/Ca·1000. Significant negative correlations were found for the relationships THg-Se/Pb, Pb-Se/Pb, Cd-Se/Pb, K-Se/Cd, Pb-Se/Cd, Cd-Se/Cd, THg-Se/THg, Pb-Se/THg, Se-Pb/Cd, Zn-Cd/Ca, and Se/Cd-Cd/Ca. The results reported here may provide a basis for establishing reference values for the tibial plateau in patients with OA who had undergone knee replacement surgery. The concentrations of elements in the bone with OA were determined by age, presence of implants, smoking, fish and seafood diet, and sport activity.

The analysis also included the relationship between Hg concentration and the fox size, and the suitability of individual organs as bioindicators in indirect evaluation of environmental mercury contamination. Determination of Hg concentration was performed by atomic absorption spectroscopy. In the analysed samples, the Hg concentration was low and the maximum value did not exceed 0.85 mgHg/kg dry weight (dw). There were no significant differences in Hg concentrations in the analysed material between males and females or between immature and adult groups. The median concentrations of Hg in the liver, kidney and skeletal muscle were 0.22, 0.11 and 0.05 mgHg/kg dw, respectively. The correlation coefficients were significant between...

The aim of this study was to examine the seasonal dynamics of allergenic mite populations in dust samples collected from sleeping places in apartments in north-western Poland. The mites were isolated from the dust using a saturated saline floating method. In 132 dust samples we determined: Dermatophagoides farinae, Dermatophagoides pteronyssinus, Euroglyphus maynei, Hirstia sp., Chortoglyphus arcuatus, Lepidoglyphus destructor, Gohieria fusca and Cheyletus sp. The greatest frequency was observed for D. farinae, D. pteronyssinus, Ch. arcuatus and Cheyletus sp., in the fourth quarter and D. farinae in the third quarter. Smaller coefficients of dominance were found for D. pteronyssinus, Ch. arcuatus and Cheyletus sp., and their greatest mean concentrations were found in the first and fourth quarters. Given the division...

They were determinated as Microsomacanthus tuvensis (Spasskaya et Spasskii, 1961) on the basis of the cirrus's and cirrus sac's size and vagina's shape. This is the first record of this species in Poland.

One of them is Microsomacanthus oidemiae Spassky et Jurpalova, 1964 (Hymenolepididae). This parasite (two not fully developed individuals, including one without a scolex) was found in the common scoter, Melanitta nigra L., (Mergini) wintering on Lake Dabie near Szczecin.

It eats fish and small invertebrates. The purpose of this study was a preliminary parasitological examination of the digestive tract of the goosander wintering on the Szczecin Lagoon. The research material were the parasites recovered from digestive tracts of 6 birds (two males and four females), which died during feeding in fishing nets in winter 2001. The birds were subject to standard parasitological examinations using commonly adopted methods. The trematodes and the cestodes found were preserved in 70% ethyl alcohol and subsequently stained using iron carmine (Cestoda) and borax alcohol carmine (Digenea) and then they were closed in Canada balsam. Nematodes were kept in 70% alcohol and cleared with 80% lactic acid or lactophenol. The parasite assemblages were analysed through calculating prevalence, intensity of infection, relative density and domination index. Also, the topic structure of t...
