    Opis:
    Objectives. The objectives of this cross-sectional study were to investigate dust exposure and respiratory health of workers in duck hatcheries in western France. Method. Ninety volunteer workers, who work in sorting rooms and/or incubation rooms, participated in exposure assessments and medical examinations. Medical examinations were performed by occupational health practitioners. They filled-in a questionnaire with the workers, followed by a lung function test on each worker. General characteristics and prevalence of chronic respiratory symptoms were described in each type of working rooms. Associations between symptoms and exposure (working room or dust level) were studied in GEE multivariate models. Results. Overall prevalence of chronic respiratory symptoms (cough, phlegm) and chronic bronchitis were similar or lower than in the reference population. However, prevalence of these symptoms was higher for those working in sorting rooms, that were associated with an increased risk of respiratory symptoms and decreased lung function. Respirable dust was also significantly associated with an increased risk of respiratory symptoms. The prevalence of asthma and rhinitis were well above those in the reference population, but did not vary among working rooms. Descriptive data suggested an occupational origin for some cases. Conclusion. Hatchery workers were at increased risk of compromised respiratory health due to dust exposure, particularly those who work in sorting rooms. Asthma and rhinitis were in excess in this population of workers. Thorough clinical examination of these workers should be performed and all exposures assessed.

    Opis:
    The present research assessed the treatment effi ciency of odorogenous pollutants in air from a hatchery hall vented on organic and organic-mineral beds of an enclosed-container biofi lter. In this study, the following media were used: organic medium containing compost and peat (OM); organic-mineral medium containing bentonite, compost and peat (BM); organic-mineral medium containing halloysite, compost and peat (HM). The concentration of odorogenous gaseous pollutants (sulfur compounds and amines) in the hatching room air and in the air after biotreatment were determined by gas chromatography. In the hatchery hall among the typical odorogenous pollutants, there were determined 2 amines: 2-butanamine and 2-pentanamine, hydrogen sulfi de, sulfur dioxide, carbon disulfi de, sulfi des and mercaptans. Ethyl mercaptan showed the highest levels as its mean concentration in the hatchery hall air exceeded 60 μg/m3 and in single samples even 800 μg/m3. A mean concentration of 2-butanamine and sulfur dioxide in the examined air also appeared to be relatively high – 21.405 μg/m3 and 15.279 μg/m3, respectively. In each fi lter material, the air treatment process ran in a different mode. As the comparison reveals, the mean reduction of odorogenous contaminants recorded in the hall and subjected to biotreatment was satisfying as it surpassed 60% for most established pollutants. These high removal values were confi rmed statistically only for single compounds. However, a low removal level was reported for hydrogen sulfi de and sulfur dioxide. No reduction was recorded in the bentonite supplemented medium (BM) for sulfur dioxide and methyl mercaptan. In the organic medium (OM) no concentration fall was noted for dipropyl sulfi de either. In all the media investigated, the highest removal rate (100%), not confi rmed statistically, was observed for carbon disulfi de. Very good results were obtained in the medium with a bentonite additive (BM) for both identifi ed amines, whose mean elimination rate exceeded 60% (p≤0.05). The present research proved that diethyl sulfi de is most susceptible to biofi ltration (over 80%) in the bed supplemented with halloysite (HM) and bentonite (BM) (p≤0.05).

    Opis:
    W publikacji przestawiono wyniki badań jakości wody odprowadzanej z wylęgarni ryb oraz wyniki badań procesu ultrafiltracji w systemie dwustopniowym z zastosowaniem membran ceramicznych o cut-off \ kDa oraz modułów 3-rurowcgo (stopień 1) i 1-rurowego (stopień II). Wykazano, że w wodzie opuszczającej wylęgarnię ryb przekroczone są wskaźniki jakości wód, tj. zawiesina ogólna, biochemiczne i chemiczne zapotrzebowanie tlenu oraz fosfor ogólny. Zastosowany proces ultrafiltracji umożliwia zmniejszenie wartości przekroczonych wskaźników, w największym stopniu w przypadku zawiesiny (100%), a w mniejszym, ale zapewniającym spełnienie wymogów środowiskowych w przypadku ChZTCr (91%) i BZT5 (73%). Stopień odzysku permeatu uzyskany w procesie dwustopniowej ultrafiltracji w czasie ok. 5 h pracy membran wynosi 87,5%.
    Research results dealing with quality of water discharged from a fish hatchery and investigation results of two-stage ultrafiltration process with the use of ceramic membranes of 1 kDa cut-off and 3-tubes module (stage 1) as well as 1-tube module (stage II) are presented in the paper. The obtained results showed that water quality indicators such as total suspended solids (TSS), biological oxygen demand (BOD), chemical oxygen demand (COD) and total phosphorus (TP) were cxceedcd in fish hatchery effluent. The proposed ultrafiltration enables one to decrease values of exceeded indicators to the highest degree in case of suspension (100%) and to the lesser degree (but still ensuring compliance with environmental requirements) in case of CODCr (91%) and BOD5 (73%). The permeate recovery ratio obtained in two-stage ultrafiltration during membrane operating time of about 5 hr was equal to 87.5%.

    Opis:
    W pracy przedstawiono wyniki badań zmian jakości wody ujściowego odcinka rzeki Wiśniówka w latach 2005-2009 w dwóch punktach - woda dopływająca do wylęgarni ryb i woda poniżej obiektu. Oznaczano wskaźniki ważne w aspekcie życia ryb w warunkach naturalnych, tj. temperaturę, pH, zawiesiny ogólne, zawartość tlenu, BZT5, ChZT, azot amonowy, azotany (III), fosfor ogólny, żelazo ogólne, a następnie porównywano ich wartości z wymaganiami określonymi w Rozporządzeniu MŚ… [2002] i Rozporządzeniu MŚ ...[2008]. Uzyskane wyniki zmian jakości wody rzeki Wiśniówka umożliwiły ocenę oddziaływania ośrodka zarybieniowego na stan czystości tego cieku w okresie 5 lat i mogą stanowić niezbędną bazę danych do zaplanowania zintegrowanej technologii uzdatniania i recyklingu wody, wykorzystywanej w wylęgarni ryb.
    Water quality at the mouth of the Wiśniówka River was analysed between 2005 and 2009 at two sampling sites: at the inlet to (I) and at the outlet from (II) fish hatchery. Water quality indicators important for fish in natural conditions, i.e.: temperature, pH, suspended solids, dissolved oxygen, BOD5, CODMn,Cr, total phosphorous, ammonium nitrogen, nitrate nitrogen, and total iron were determined. Obtained results were compared with standards given in the Decrees of the Polish Ministry of Environment of 4.10.2002 and 20.08.2008. The aim of the study was: evaluation of 5-year changes of water quality and building a database for the development of integrated technology for water treatment and recycling at a fish hatchery.

    Opis:
    The aim of the presented study was to determine the health status of workers occupationally exposed to moderate amounts of organic dust, employed in a modern hatchery with an effi cient ventilation system. A group of 32 hatchery workers was examined. As a reference group, 50 urban dwellers not exposed to any kind of organic dust were examined. All people were interviewed for the presence of work-related symptoms and subjected to physical and spirometric examinations. Blood sera were examined for the presence of precipitins against 13 antigens associated with organic dust, and for the presence of total and chicken-specifi c No signifi cant differences were found between the spirometric values in the group of hatchery workers and the reference group. Positive precipitin reactions were noted mostly with the antigens of Gram-negative bacteria associated with organic dust. The frequencies of positive reactions to antigens of Escherichia coli and Acinetobacter baumannii in hatchery workers were signifi cantly greater compared to the reference group (p<0.05). Precipitin reactions to Gram-positive non-branching bacteria, actinomycetes, fungi and bird protein, were rare or absent. The mean concentration of total IgE in sera of hatchery workers was nearly 3 times greater compared to the reference group, and the difference proved to be statistically signifi cant (p<0.05). No specifi c IgE antibodies against chicken feathers were detected in the blood of hatchery workers and referents. In conclusion, the examined hatchery workers showed a moderate frequency of work-related symptoms, no decline in lung function and low reactivity to most microbial and bird protein allergens. These results suggest that the effects of exposure to organic dust in workers of modern hatcheries with an effi cient ventilation system are less compared to the workers of poultry farms, such as broiler or egg laying houses.

    Wody zasilające i opuszczające wylęgarnie ryb muszą być poddawane efektywnemu oczyszczaniu ze względu na konieczność optymalizacji procesu inkubacji ikry i ochrony środowiska wodnego. Celem badań jest przetestowanie procesu ultrafiltracji i membran ceramicznych l kDa, jako metody usuwania zawiesiny, fosforu i żelaza oraz redukcji poziomu BZT-, i ChZT z wód krążących w obiegu zamkniętym malej wylęgarni. Uzyskane wyniki wskazują, że badana technika membranowa może być wykorzystana w gospodarce wodno-ściekowej wylęgarni do recyklingu wody.
    Feed and wastewator from aquaculture facilities must be effectively treated for environmental and embryological reasons. The objective of this study was to evaluate ultrafiltration process using a ceramic 1 kDa membrane asa treatment option for removal of total suspended solids, total phosphorous and iron, and reducing BOD and COD level in closed loop of cyclic water in fish hatchery. The obtained results indicate that the tested membrane and technique employed can be used in full-scale treatment technology for culture water recycling.

    Opis:
    A novel biofi lter containing organic, bentonite and halloysite media was applied for elimination of microbial pollutants from the air of an industrial hatchery. The concentrations of total mesophilic bacteria, Gram-negative bacteria, thermophilic actinomycetes, dust and bacterial endotoxin were determined in the air of hatchery during 2 months before installation of the biofi lter, and during 6 months after installation of the biofi lter, at the inlet and outlet ducts from each medium. Before installation of the biofi lter, the concentrations of total mesophilic bacteria, Gram-negative bacteria, thermophilic actinomycetes, dust and endotoxin in the air were within the ranges of 0.97- 131.2 × 103 cfu/m3, 0.0-34.4 × 103 cfu/m3, 0.0-0.02 × 103 cfu/m3, 0.37-4.53 mg/m3, and 50.9-520,450.4 ng/m3, respectively. Enterococcus faecalis and Gram-negative bacteria (Acinetobacter spp., Escherichia coli, Enterobacter cloacae, and other species) prevailed among bacterial species recovered from the air of the hatchery. A total of 56 species or genera of bacteria were identifi ed in the air samples taken in the examined hatchery; of these, 11, 11 and 6 species or genera respectively were reported as having allergenic, immunotoxic and/or infectious properties The concentrations of total mesophilic bacteria, Gram-negative bacteria, Enterococcus faecalis and endotoxin found at the inlet duct of the biofi lter after its installation were signifi cantly smaller compared to those recorded before its installation (p<0.05). The concentrations of Gram-negative bacteria, Enterococcus faecalis and dust found at the outlet ducts of biofi lter after its installation were signifi cantly smaller compared to those recorded at the inlet duct of the biofi lter (p<0.01). The concentrations of total meso-philic bacteria were also smaller at the outlet ducts of the biofi lter compared to that at the inlet duct; however, the difference was not signifi cant because of the massive growth of Streptomyces species in the biofi lter’s media which contaminated the outcoming air. In conclusion, the applied biofi lter proved to be effective in the elimination of potentially pathogenic bacteria, dust and endotoxin from the air of the hatchery. The effi cacy of the biofi lter could be improved by the inhibition of the Streptomyces growth in the media of the biofi lter.

    Opis:
    The effect of conditioned waste from poultry hatchery on selected parameters of light soil was examined. Basing on the obtained results it was found that after applying the conditioned waste, the contents of organie matter increased, which was manifested in the increase in both mean content of organie carbon and total nitrogen in soil. Furthermore, a mean significant increase in the contents of available forms of phosphorus and magnesium was also found. As the effect of applying both the organie waste from poultry hatchery and the postcellulose lime, a significant increase in exchangeable acidity and a decrease in contents of available forms of potassium were observed with reference to the control. The use of postcellulose lime reduced the contents of available forms of magnesium in soil.
    Badano wpływ kondycjonowanego odpadu z wylęgarni drobiu oraz wapna pocelulozowego na wybrane parametry gleby lekkiej. Na podstawie uzyskanych wyników badań stwierdzono, że po zastosowaniu kondycjonera glebowego wzrosła zawartość materii organicznej, co przejawiało się wzrostem średniej zawartości węgla organicznego oraz azotu ogółem w glebie. Ponadto stwierdzono w tych warunkach znaczny wzrost średniej zawartości przyswajalnych form fosforu i magnezu w glebie. W wyniku zastosowania zarówno odpadu organicznego z wylęgarni drobiu, jak i wapna pocelulozowego, stwierdzono znaczny wzrost wartości kwasowości wymiennej oraz zmniejszenie zawartości przyswajalnych form potasu w porównaniu z obserwowanymi w obiekcie kontrolnym. Zastosowanie wapna pocelulozowego powodowało zmniejszenie i przyswajalnych form magnezu w glebie.
