A continuous 2-year volumetric aerobiological survey was conducted in Berhampore town, a centrally located and representative part of West Bengal, India. The aim of the study was to assess the allergising potential of airborne pollen grains of West Bengal. A total of 31 pollen types were identified of which Poaceae (grasses) pollen showed maximum frequency, followed by Cyperaceae, Cassia sp., Acacia...
Pollen concentration in the atmosphere of Lublin (eastern Poland) was studied by means of volumetric method using Hirst sampler (VPPS 2000, Lanzoni) in 2001-2002. The pollen trap was mounted at the height of 15 m in the centre of Lublin. On the basis of analysis of mean daily values of pollen concentration, the pollen calendar was constructed for 16 taxa producing the allergenic pollen: Alnus, Corylus,...
Air sampling was performed during picking and sorting of hop (Humulus lupulus) cones on 19 hop farms located in eastern Poland. The concentration and composition of airborne microflora and the concentration of airborne dust and endotoxin were determined. Additionally, 7 samples of settled hop dust were collected and examined for the presence of microorganisms and endotoxin. Total concentrations of...
House dust is an important source of different toxic metabolites as well as allergens, including those of fungal origin, in the indoor environment. A bio-assay employing 1-day-old chick tracheas was used to characterize airway effects of 2-butanone and dimethylsulphoxide (Me2SO) extracts of 23 dust samples collected from water damaged (13) and control (10) Danish schools. Direct microscopical analysis...
The aim of this study was to determine the prevalence of spirochete Borrelia burgdorferi s.l. in ticks Ixodes ricinus and mosquitoes Aedes spp. within the Bukowa Forest, collected between 2000 and 2001. The study covered 215 ticks (193 nymphs and 22 adults) and 947 mosquitoes female of the genus Aedes. Spirochetes of em>Borrelia burgdorferi s.l. were detected in the arthropods studied with the...
This study tested the effectiveness of benzyl benzoate (BB) in killing Tyrophagus putrescentiae (Schrank) mites when using the method utilized by regular consumers. The efficacy of the BB sprays was determined in laboratory experiments and semi-field experiments with mattress and mattress pad pieces. The mites were counted and their living status determined at different time points microscopically...
Neighbours of intensive livestock production facilities frequently complain of odour annoyance. They are also concerned about potential negative health effects of environmental exposures to livestock emissions. Quality of life (QoL) was assessed in residents of a rural community neighbouring an area with high concentration of animal farms. A postal cross-sectional survey was carried out among the...
The clinical evaluation of newly developed asthma in an adult should always include consideration of his occupational environment, since an abundance of different exposures, which are known causes of asthma, occur in workplaces. Two types of occupational asthma (OA) are distinguished, by whether they appear after a latency period: 1) Immunological OA, characterised by a latency period, caused by high...
Aerosols generated in dental operations are a source of exposure to microorganisms proliferated within dental unit waterlines (DUWL) biofilm. It has been suggested that presence of Legionella species in these aerosols may contribute to potential health hazards for dental staff and patients. The article attempts to provide a brief overview of the current knowledge about Legionella, its prevalence in...
Sera of 500 inhabitants of north-eastern Poland, 450 suspected for Lyme borreliosis and 50 blood donors (control group), were analysed for the presence of IgG antibodies against Anaplasma phagocytophilum, the causative agent of human anaplasmosis (HA), known so far as human granulocytic ehrlichiosis (HGE). Forty one (9.1%) sera of the study group and one serum (2%) of the control group were positive...
We hypothesise that inhalant exposure to mycotoxins causes developmental outcomes and certain hormone-related cancers that are associated with grain farming in an epidemiological study. The aim of the present study was to identify and validate determinants of measured trichothecene mycotoxins in grain dust as work environmental trichothecene exposure indicators. Settled grain dust was collected in...
A group of 150 people occupationally exposed to dust from herbs were examined. The examined group consisted of 47 thyme farmers, 32 chamomile farmers, 31 sage farmers and 40 workers of herbs processing industry. As a reference group, 50 urban dwellers, not exposed to any kind of organic dust, were examined. Skin prick tests and precipitin tests were conducted with, respectively, 4 and 11 microbial...
The study was carried out from April 2000-March 2001. During this period 49 samples of dust, litter, debris and residues from cages and run-offs of mammals, birds and reptiles in the Silesian Zoo, were examined for the presence of mites, especially the allergenic taxa. Mites were extracted using the Berlese method and preserved in 70% ethanol. For identification, the mites were mounted in Hoyer's...
Alnus pollen is an early component of the annual atmospheric aerosol of the north-west regions of Spain, which causes the first occurrence of allergic symptoms. Seasonal and intra-daily variation of Alnus pollination, and the influence that main meteorological parameters exert, was studied in this paper. Monitoring was carried out from 1993-2002, by using two Lanzoni VPPS 2000 volumetric samplers...
The aim of our study was to estimate the prevalence of asthma and some respiratory symptoms and diseases in schoolchildren from rural regions of Poland in 2001 and to compare these data with previous estimations in 1995. Repeated cross-sectional epidemiological studies were performed among 594 primary schoolchildren in 1995 and 541 in 2001 using the same standardized questionnaire. Lifetime prevalence...
An explorative field study was conducted to assess residential exposure to pesticides, regularly applied in bulb farming. House dust floor samples were taken from homes of bulb farmers (n = 12) and from homes in close proximity to a bulb field (i.e. non-farmers) (n = 15). Samples were analysed for 7 pesticides used by bulb growers in the sampling period. Of these pesticides, chloropropham, flutolanil...
The presence of antibodies against Chlamydophila (Chlamydia) psittaci in small mammals (Insectivora, Rodentia) in the region of East Slovakia are presented. The hosts were caught in several areas of Slovakia in habitats with different levels of anthropogenic disturbance. Research was carried out during 2000-2002. The authors examined 1,947 sera coming from 4 insectivore and 10 rodent species. Each...
Investigations on airborne fungi in a poultry house, a swinery, a feed preparing and storing house, a grain mill, a wooden panel producing factory, and organic waste recycling facilities have been carried out in Lithuania. Low concentrations of fungal spores were detected in the wooden panel producing factory, the swinery, the feed preparing and storing house, and the poultry house; moderate concentrations...
The seroprevalence of human granulocytic anaplasmosis (former human granulocytic ehrlichiosis, HGE) has been documented in several studies, but little data exists on incidence rates in healthy individuals. In a prospective study, we tested 125 healthy adults (mean age 43 years) - workers of the Białowieża Primeval Forest National Park, north-eastern Poland - for Anaplasma phagocytophilum IgG antibodies...
