Introduction
The results of the study carried out in recent years in many countries ^ indicate that about 87% of the time people spend ^ in public buildings? What big Coiled falls on time spçdzony in the workplace. One? ^ smokers factors may pose a threat dia health at workplaces s office ^ ^ ^ ce equipment secrete contaminated water spray into the air. Microorganisms which naturally occurs ^ s ^ in the air in wiçkszosci dia harmless man. In the event of the occurrence of an additional source of contamination, resulting ^ dual? the presence of pathogenic microorganisms in the process water at the workplace, the risk of occurrence ^ sleep and respiratory infection but becomes greater (1.2).Accordingly high air humidity and prolonged exposure time employee of industrial plants for this type of threat is wi sic ^ Zac? many dysfunctions of respiratory conditions such as asthma, allergic rhinitis, bronchitis, respiratory failure, diseases of the cardiovascular system, inflammation of the gastrointestinal tract, tuberculosis, allergic reactions, as well as sinusitis, conjunctivitis and acute viral infections of the upper respiratory tract (3). The threat to human health dia ^ can create not only the microorganisms but also their metabolites - endotoxins and mycotoxins, which bioaerozolach importance ^ ^ play a role, causing inflammatory reactions ^ c ^ c and contribute ourselves to the deterioration of lung function (3-6).
One? microorganisms, which can wystçpowac in bioaerosol and can pose serious risks to human health dia, p ^ bacteria? Legionella (7-9). Infection with these bacteria, the CPU via inhalation aerosol containing the micro-organisms of water, whose source p ^ colonized by aquatic plants of various types and destination (9,10). Susceptible s ^ ^ especially for non-transmission systems warmer water with a temperature of 20-40 ° C, the construction of which is conducive to stagnation of water and creating sic obrostów microbiological Internal outputs office space ^ Dzen and water systems (1,2,8,10-12). Image khniczny diseases in developing sic nastçpstwie tract infections, inhaled ^ ^ can take formç Legionnaires' disease pulmonary extend in the form of pneumonia, usually of ciçzkim mileage? The predominant symptoms from respiratory or so. Pontiac fever, which runs? ^ ^ elevated body temperature and diffuse miçsniowymi and articular pain (1,2).
? Due to the prevalence of colonization, water systems risk of infection relates to a large rectilinear population, including people exposed to inhalation of contaminated spray of water during the performance of work. Cases of infection with bacteria? Legionella among others in workers health care facilities and offices stornatolo - cal (13-16), handling and cooling systems kJimatyzacyjnych ^ smokers (17), employees waste water treatment (18) and engaged in the handling of all types of cleaning devices ^ smokers and cleaning in industry and food processing machinery (19-22). Used in factories mechanical processing device slides wash ^ ^ ce causing the formation of aerosol of water, which exposed s ^ workers in their operation and in the immediate vicinity, but there is no data on registered cases of Legionnaires' disease among them.
The aim of the present study was to analyze the type and czçstosci occurrence of ailments of the respiratory system. It was carried out on the basis of a survey, which objçto employees chosen bets mechanical processing of glass exposed to water spray. Wstçpnie rated ^ also the microbiological quality of air in workplaces and water taken? Water spray generating devices (a pilot study).
MATERIAL AND METHODS:
A survey study Overall I'd objçto 131 employees in 9 factories mechanical processing of glass belonging to the enterprise of which has oddziaîy in different czçsciach Polish. The survey was carried out at the workplace. Responses were received from all the staff of the change in working on the study directly in the production, who expressed zgodç on wziçcie participate in the study. The survey included five groups of data:
1. Demographic data: age, sex, place of residence (urban / rural).
2. 2. Data on work and leisure:
- time working in the plant and in a certain position,
- the type of operations performed,
- the distance jobs from the source of water spray,
- interviews of your previous experience? uwzglçdnieniem exposure to:
- potentially harmful biological agents, chemical and physical
- use? Spray at work (at least 3 times a week)
- use? water recreation (at least 1 time per year: a swimming pool, a pool? hydromassage and others).
3. Data relating to those found in the past respiratory diseases, hospitalization? their reason and long lasting ailments, which included:
- sic cough lasting for at least 3 months of the sequence in the last 2 years
- permanent or recurrent ^ ^ ^ exertional dyspnoea, wystçpujaca. ^ systematically and felt no less frequently than every 4 weeks
- recurrent or prolonged pain in the chest
- wheezing.
4. The data relating to the acute symptoms of the respiratory system? accompanied by systemic symptoms or without them, which wystçpowaly of the sequence in the last year preceding the survey;Occurrence of symptoms LIABLE team legionelozie embolism and a fever of Pontiac, which was composed sic simultaneous Occurrence of fever, chills, aches miçsniowych and / or joint pain, headache,? accompanied by dyspnea, coughing and tightness in the chest.
5. Data on smoking relate ourselves to the age at commencement smoking, przeciçtnej number of cigarettes smoked per day, attempts to quit smoking and cigarette smoking breaks longer than one year. In the case of former smokers were also asked about the age at which smoking zaprzestaU.
In the course of the survey were measured distances job of aerosol sources of water. It constituted the base of varying the exposure of workers and allowed the wyodrçbnienie 2 treatment groups:
* persons employed in the direct bUskosci devices ^ Dzen produce ^ smokers water spray, which for becomes greater ^ Coiled working time remained at a distance of 20 m from that point,
* persons, whose post was sic at a distance of more than 20 meters from the source of aerosol.
Distance TC selected? ^ occurs due to sun off first? the above groups direct exposure to inhalation of water spray immediately after his release? ^ Dzen technological devices that do not wystçpowalo of employees across the group. He then assesses the demographic differences ^ ce occurs between the above groups associated ^ length and course of employment, differences relating to smoking and behaviors that may influence the risk of infection by bacteria? kind of Legionella, verifying their statistical significance ^ chi-square test.
In a further step czçstosci study compared the occurrence of acute and chronic dolegUwosci from the respiratory tract of workers of both the above groups? uwzglçdnieniem age, drinking, smoking cigarettes using logistic regression analizç and obUczaj ^ c adjusted odds ratios with 95 percent confidence interval.
Microbiological testing of air and water technology Water samples were collected simultaneously and entrusts points at workplaces, which was generated water spray. Samples of process water (1000 m) indicates the presence of bacteria? type of Legionella according to PN-EN ISO 11731-2: 2008 (23) and overall ^ for the number of microorganisms according to BS EN ISO 6222: 2004 (24).
Investigation of the microbiological contamination of air samples was carried out metodi ^ collision with cameras Micro Bio ( Air Sampler MB 1 plus, prod. De Ville, United Kingdom) and MAS- 100 (prod. Merck, Germany). The determination towards the total number of bacteria and the total number of molds and fungi. Objçtosc collected air samples ranged 100-300 1 día total number of bacteria, mold and fungi.
RESULTS
The survey objçto Overall an 131 workers aged 18-57 years (mean age: 32.1 years) employed directly in the production, including 113 mçzczyzn (86.3%) and 18kobiet (13.7%). Time employment of the respondents ranged from 3 miesiçcy to 15 years (average 4.4 years). In the group of cigarettes smoked a total of 68 patients (51.9%). Former smokers accounted for 25.2% of the respondents, while non-smokers - 22.9%. Altogether a group of people ever smokers smoke ^ I counted 101 people (71.1%). The number of cigarettes smoked was przeciçtnie 7.3 pack-years. ? showers sic located in work benefited at least 3 times a week 58 respondents (44.2%), and kajrielowy pool or water park was visited at least once a year for 69 patients (52.7%). Distance job of aerosol sources amounted to 1-200 m (average: 40.1).
Acute dolegUwosci on the part of the respiratory system in a body ^ in the year preceding the survey reported by 37 subjects (28.2%). Przewazaîy symptoms of rhinitis, upper respiratory tract - runny nose? ^ nasal obstruction, sore throat, cough, sometimes?accompanied by a heightened body temperature. None? These symptoms studied trwaîy no longer than 3 weeks. ? above a group of 7 people wystajrienie team reported symptoms that may be suspected Legionnaires' disease, including pulmonary form of the disease. At the same time the band suger sic Occurrence a heightened fever, cough, dyspnea, pain or tightness in the chest and spilled miçsniowych and joint pain. It should however be podkresUc that the above non-specific syndrome can not be the basis for the diagnosis of legionellosis, but at most indicate a possibility of such ^.None? the workers interviewed in the course of employment in these factories did not require hospital treatment? Because of dolegUwosci or respiratory diseases.
Occurrence dolegUwosci chronic respiratory had volunteered by 38 respondents (29%). Most often wystçpujaca ^ ^ dolegUwosci was a long-lasting cough, which reported 16% of respondents, of which 62.3% were cigarette smokers. It was reported less frequently recurrent exertional dyspnea (12.9%), wheezing (12
