Background. Organochlorine pesticides (OCPs), which act in a similar way to natural hormones, lead to disorders of the endocrine system in animals and humans (endocrine disruptors). Among food products, fish are considered to be the main source of these compounds in the human diet, posing a health risk to consumers. The aim of this study was to determine concentrations in fish and their environment of certain organochlorine pesticides in fish and their environment and to estimate daily intakes (EDI) of individual pesticides from the fish examined. Materials and Methods. Analyses aimed at detecting the pesticides (OCPs: α-, β-, γ-HCH, heptachlor, heptachlor epoxide, aldrin, dieldrin, and endrin) included samples of water taken from the lower stretch of the Oder River and three fish species, which are commonly harvested in that area. Quantitative analyses were carried out using the Capillary Gas Chromatography/Mass Spectrometry method in a GC MSD HP 6890/5973 apparatus. Results. The study found that concentrations of OCPs in fish gonads were significantly higher than in the muscle tissue. The dominant pesticide compound in gonads of roach and bream was γ-HCH, whilst β-HCH predominated in the muscle tissues of those fishes. Endrin, on the other hand was the major pesticide in the muscle tissue of ide. Mean concentrations of OCPs in the gonads ranged from 0.385 to 0.544 ng∙g–1 wet weight (w.w.) for α-HCH, 0.745 to 0.832 ng∙g–1 w.w. for γ-HCH, 0.479 to 0.576 ng∙g–1 w.w. for dieldrin, and 0.381 to 0.684 ng∙g–1 w.w. for endrin. Concentrations of the studied compounds in the water taken from the Oder River followed the order: endrin > γ-HCH > α-HCH > dieldrin > β-HCH > heptachlor ≈ aldrin > heptachlor epoxide. The highest log BCF was obtained for fish gonads and ranged from 1.5 (endrin) to 3.4 (heptachlor epoxide). Estimated daily intakes (EDI) varied from 0.0014% to 0.097% of the acceptable daily intake (ADI). Conclusion. This study revealed no direct risk linked to the consumption of fish captured from the study area. However, from the ecological aspect, the accumulation of organochlorine residues in fish gonads has been considered a dangerous phenomenon, as this may result in decreased reproduction of fish and other aquatic organisms, potentially leading to their extinction.

The aim of this study was to estimate the degree of DDT and its metabolite bioaccumulation (biotasediment accumulation factor, BSAF and biota-water accumulation factor, BCF) in certain aquatic biota collected from the lower Oder River. The study comprised surface water and sediments, as well as soft tissue of compressed river mussel (Anodonta complanata) and certain organs of roach (Rutilus rutilus) and spinycheek crayfish (Orconectes limosus). Regarding a 30-year-old ban on DDT use in Poland, relatively low concentrations of the compound were expected. DDT and its metabolites were detected in all the examined samples. ΣDDT levels in water and sediments averaged 0.157 ± 0.068 µg/dm³ and 11.478 ± 2.292 µg/kg d.w., respectively. Roach organs contained higher levels of these compounds than crayfish and bivalves. DDT was accumulated mainly in the liver and gonads (45.823 ± 9.845 and 19.815 ± 4.854 µg ΣDDT/kg w.w., respectively). In roach organs p,p’ DDE predominated. BSAF values for p,p’ DDE and p,p’ DDD in the liver and p,p’ DDE in the gonads exceeded the predicted theoretical value (2.4). In water and sediment samples from several sites, the DDT/DDE ratio was higher than 1, which indicated fresh input of DDT in the studied area or inhibition of its breakdown.

The aim of this study was the toxicological risk assessment for consumers on the basis of toxic equivalents (TEQs) from fish netted from Miêdzyodrze waters. The quantitative analysis of dioxin-like compounds (non- and mono-orto PCBs) were conducted using the capillary gas chromatography method (GC MSD HP 6890/5973). Toxic equivalents values were dependent of the most toxic congeners concentration, e.g. PCB 126 and PCB 169. Mean TEQ ranged from 0.03 ± 0.02 ng-TEQ/kg w.w. to 0.09 ± 0.01 ng-TEQ/kg w.w. The highest equivalents were received for ide’s meat and the lowest - for roach’s meat. Consideration of the mean consumption of fish in Poland and the highest TEQs of examined fish ascertained that their meat is safe for consumers from the hygienic and toxicological perspective.

The aim of the study was to determine the species composition, prevalence and intensity of parasitic enteric infections in cows in relation to farm management system. Prevalence of gastrointestinal nematodes and Eimeria protozoans was determined from coproscopic examinations using Willis-Schlaf flotation. The species composition of coccidia was determined from morphological characters and the time of oocyst sporulation. Fluke liver eggs were detected by decantation. The average rates of parasitic infections were 67.42%, in the biodynamic farm, 62.14%, in the organic farms, and 63.26%, in the conventional cattle farm. Cows managed in the biodynamic farm suffered from infections by Eimeria protozoans and gastrointestinal nematodes, whereas Eimeria, gastrointestinal nematodes and Moniezia sp. were found in the organic farms. In cows of the conventional farm, we found Eimeria, gastrointestinal nematodes, Moniezia sp. and trematodes: Fasciola hepatica and Paramphistomum sp. The average intensity of Eimeria sp. infection in cows by farming system was as follows: 71 OPG (oocysts per gram of feces) in the biodynamic farm, 57 OPG in the organic farm and 71 OPG in the conventional farm. The mean intensity of gastrointestinal parasites was 290 EPG (eggs per gram feces) in the biodynamic farm, 455 EPG in the organic farm, and 228 EPG in the conventional farm. The average Moniezia infection intensity in cows was 125 EPG, in the organic farm, and 50 EPG (eggs per gram feces), in the conventional farm. It is noteworthy that the intensity of gastrointestinal nematode infection of cows in the biodynamic farm was very low (290 EPG) despite a high prevalence of infection (67.42%). A similar situation though was found in the cows managed in the conventional way.

The presence of invasive forms of parasites in the soil represents a potential threat to public health, especially for children. The aim of the study was to determine the degree of contamination with geohelminth eggs of soil samples collected from sandpits and playgrounds in the Szczecin area. The findings showed overall prevalence of soil samples contaminated with geohelminth eggs in the soil and sand of play areas in Szczecin at 41.4%. Four species of parasites have been identified: Toxocara spp., Toxascaris leonina, Dipylidium caninum and Trichuris spp. The greatest proportion of infected samples from sandpits contained Toxocara spp. eggs, comprising 22.7% of samples; however, the dominant parasite found in the samples from the play areas was Toxascaris leonina (28.6%). As contamination of the soil with parasite eggs constitutes a risk of infection with parasitic diseases in humans, it is necessary to monitor the presence of geohelminth eggs in soil and to implement activities aimed at prevention of their occurrence.

The emergence of drug resistance among parasites is a side effect of the common use of chemotherapeutic agents in horses. Combating parasites typically involves routine deworming treatments twice a year (before and after the grazing season). However, in grazing farming this treatment may be insufficient. The aim of the study was to evaluate the effectiveness of programs to combat the invasion of strongyles (Strongylidae) in horses in the selected stables of Western Pomerania. Coprological examination was conducted in 85 horses from three stables located in Western Pomerania. Horses from all three stables remained in the pastures in the period from spring to late autumn, and deworming treatment was performed twice. The examination of horses has found nematodes of the family Strongylidae. The average prevalence of infection in horses in the studs tested was 36.16% for Strongylinae, and 58.49% for Cyathostominae. Administration of the medication twice did not eradicate the invasion of strongyles in the horses investigated. A significant reduction of strongyle invasion was observed directly after treatment, followed by rapid reinvasion. It appears necessary to monitor the effectiveness of deworming treatments by performing parasitological examination of feces. The participating stables should develop and implement new strategies to combat parasitic invasions in horses that will be adapted to the environmental conditions (the life cycle of parasites).

The aim of the study was to determine the prevalence and intensity of parasitic gastrointestinal infections in free-range chickens from the West Pomerania province. Experimental material for the study was taken from 10 farms. Breeds raised in farms participating in the study included miniature chickens called Polish Lilliputians and Greenlegged Partridge. A total of 104 samples of faeces were examined. The Willis-Schlaff flotation method was used to assess the prevalence of infection, and McMaster’s method to evaluate the intensity. The presence of gastrointestinal parasites was found in 9 of the 10 farms. Oocysts of the genus Eimeria and eggs of gastrointestinal nematodes Ascaridia galli, Heterakis gallinarum and Trichostrongylus tenuis were isolated from the chicken faeces. Coccidiosis was found to be dominant parasitosis. The prevalence of infections on these farms with protozoa of Eimeria spp. was on average 32.7%, while for nematode species they amounted to 9.6% for Ascaridia galli, 5.7% for Heterakis gallinarum and 12.5% for Trichostrongylus tenuis. The results indicate the need to take preventive measures, designed to eliminate/reduce the risk of parasitoses in poultry from free-range systems. Focus should be placed on the hygiene of the farming conditions.

The aim of this study was to determine the effect of exploitation of recreation horses horse in the summer season on the selenium concentration in serum and the values of chosen haematological parameters. Blood to analyse was sampled from horses used in recreation in two horse riding centres located in the Western Pomeranian Province. Stable 1 (8 horses), situated in a seaside resort, with rides being led mostly in a riding arena, less often in the field. Large rotation of riders with different level of riding advancement has been observed, with prevalence of novice riders and horses working on the lunge. Stable 2 (18 horses), situated in a rural area, far away from large cities; in the holiday season, horses work maximum 4 hours a day, with prevalence of rides of weak and moderate intensity, being led in the field, with riders with average and high level of riding advancement and small rotation of riders. Blood samples were drawn twice: in the first days of July (start of the holiday season) and in the last days of August (end of the holiday season). Average selenium concentration in the blood serum of horses in Stable 1 decreased significantly during the holiday season. Mean values of chosen analysed haematological parameters of the horses in both riding centres did not undergo any significant changes during their use in the holiday season. Significant increase in the leukocyte and platelet counts after the holiday season was observed in the blood of horses in Stable 1. The horses of Stable 2 were characterised by significantly higher mean haematocrit value (39.14%) when compared to those in Stable 1. No significant correlations were found between the Se concentrations and chosen haematological parameters. The observations being carried out confirm the occurrence of Se deficiencies in horses in the Western Pomerania. As it appears from the performed study, intensive recreational horse use (5-6 hours of work per day) affects the significant decrease in serum selenium concentration, which suggests that application of appropriate supplementation in the nutrition of intensively working horses is necessary. Insufficient number of studies and ambiguous results concerning the effect of horse use on the WBC and the platelet counts prompt to undertake more broader observations in this respect.

The objective of the study was to determine selenium status and its distribution in the organs of free living foxes from selenium deficient areas of north-western Poland. Samples of organs harvested from 40 foxes shot during the 2008-2009 hunting seasons served as experimental material. Selenium concentration in the organs was determined spectrofluorometrically. Selenium distribution in tissues depends largely on its dietary content. Our study indicated that concentrations of selenium in the examined organs followed the order: kidney>liver>spleen>lung>heart and kidneys were the organ with the highest retention of this element. Mean selenium concentration in fox kidneys was 0.60 ± 0.15 μg/g wet weight. Several times less selenium on average was found in the liver (0.27 ± 0.09 μg/g w.w.), lungs (0.17 ± 0.06 μg/g w.w.), spleen (0.19 ± 0.06 μg/g w.w.) and heart (0.13 ± 0.05 μg/g w.w.). All the animals studied were deficient in selenium.

The objective of the present study was to determine the prevalence of infection with Eimeria and Cryptosporidium sp. among Polish cows (n=60) and those imported as in-calf heifers from the Netherlands (n=75) to Poland. In addition, faecal samples of 12 farm workers were tested for Cryptosporidium sp. The prevalence of infection with Eimeria was evaluated based on coproscopic examination using the Willis and Schlaf flotation technique. The presence of Cryptosporidium sp. in faecal samples was tested using the modified Ziehl-Neelsen staining method, as well as aN enzyme immunoassay. The coproscopic examination showed that 30.7% of the cows imported as in-calf heifers from the Netherlands to Poland were infected with Cryptosporidium sp. These animals also showed 30% higher, in comparison to Polish cows, the prevalence of infection with Eimeria bovis, which is regarded as one of the most pathogenic species. None of the Polish cows was infected with Cryptosporidium sp. Farm workers were found to be negative for Cryptosporidium coproantigen. The annual rate of infection with Eimeria in the cows imported as in-calf heifers from the Netherlands averaged 10.7% and was much lower than for Polish cows (18.3%). When importing cows from the Netherlands to Poland, attention must be given to Cryptosporidium sp.

Migratory smelt (Osmerus eperlanus eperlanus L.) may be perceived as a valuable indicative organism in monitoring the current environmental status and in assessment of a potential risk caused by selenium pollution. The aim of the study was to compare the selenium content in the European smelt from the Bay of Pomerania, Gdansk, and the Curonian Lagoon. The experimental material consisted of smelt samples (muscle) caught in the bays of Gdansk and Pomerania and the Curonian Lagoon (estuaries of the three largest rivers in the Baltic Sea basin: the Oder, the Vistula and the Neman). A total of 133 smelt were examined (Pomerania Bay n = 67; Gdansk Bay n = 35; Curonian Lagoon n = 31). Selenium concentrations were determined spectrofluorometrically. The data were analyzed statistically using one-way analysis of variance, calculated in Statistica PL software. The region of fish collection significantly affected the content of selenium in the examined smelts. The highest content of selenium was observed in smelt caught in the Bay of Gdansk (0.236 μg g-1 w.w.), then in smelt from the Pomeranian Bay (0.165 μg g-1 w.w.), and the lowest in smelt obtained in the Curonian Lagoon (Lithuania) (0.104 μg g-1 w.w.). The low concentrations of selenium recorded in the smelt show that there is a deficiency of this element, especially in the Curonian Lagoon (Lithuania). Geochemically, Poland and Lithuania are selenium deficient areas. Migratory smelt may serve as indicative organisms of environmental levels of selenium.
