A further study of air pollution in diesel bus garages
Concentrations of smoke, polycyclic aromatic hydrocarbons (PAHs) and some gaseous air pollutants (sulfur dioxide, carbon monoxide and oxides of nitrogen) were measured in diesel-bus garages in London (United Kingdom), and compared with observations in the same garages 23 years previously. Though the background concentrations of smoke and PAHs were significantly reduced compared to the earlier observations (mostly due to anti-pollution laws), the benzo(a)pyrene content of the air inside the garages (due to exhaust fumes from the buses) has remained basically the same.

Diseases caused by inhalation of microbial dust in farmwork - Medical, microbiological and technical aspects. Proposed countermeasures
Sjukdomar orsakade av inandat mikrobiellt damm i lantbruksmiljö - Medicinsk, mikrobiologisk och jordbruksteknisk inventering. Förslag till motĺtgärder [in Swedish]
Air inhaled during the handling of mouldy material may contain more than 109 microorganisms/m3 and cause alveolitis. Preventive measures include information about the hazards of inhaling mould dust and about correct preservation techniques. Simple supplementary preservation methods should be developed as well as better methods to store woodchips, sawdust and straw, to monitor moisture and temperature of stored material and to reduce exposure to dust. Research is needed on harmful components of microbial dust and on safe exposure levels. The significance of mycotoxins and endotoxins should be studied further. More technical experts are needed to co-operate with physicians in the rehabilitation of patients with alveolitis.

Determination of molybdenum aerosol in workplace air
Opredeljane na molibdenovi aerozoli văv văzducha na rabotnata sreda [in Bulgarian]
A rapid method of quantitative determination of molybdenum in workplace air was developed. The method is based on the reaction of hexavalent molybdenum cation with rhodanate anion in the presence of a reducing agent. The concentration of molybdenum is determined from the intensity of the colour of the resulting molybdenum pentarhodanate. A sensitivity of 0.1µg is obtained by this method. The studies carried out with this method during the process of welding with electrodes containing 2.5% molybdenum in their coating showed that the concentration of molybdenum aerosols in the air investigated was under the MAC.

Air contaminants in the processing of plastics. Polyolefins, polyvinyl chloride, styrene thermoplastics
Ilman epäpuhtaudet muovien työstössä. Polyolefiinit, polyvinyylikloridi, styreenikestomuovit [in Finnish]
The major plastics of commercial interest are polyethylene, polypropylene, polyvinyl chloride, and polystyrene with various modifications. The machining of plastics gives rise to impurities in the workplace air. The concentrations of the individual compounds usually stay well below their respective hygienic limit values. Nevertheless, the sum concentration of the contaminants can be substantial and may even exceed the limit values set for mixtures of compounds. The most important contaminants are aerosols (fumes). Higher machining temperatures effected higher levels of contaminants than did lower temperatures. Extensive hot surfaces (as in the machining of large items and films) emitted greater amounts of oxidised compounds (aldehydes and organic acids) than was the case during the production of small pieces. The additives in the plastics appeared to vapourise and decompose more readily than the polymers themselves.

Establishing maximum allowable emissions from low-lying industrial sources
Ustanovlenie predel'no dopustimyh vybrosov ot nizkih promyšlennyh istočnikov [in Russian]
Description of a mathematical approach to standard-setting developed by the research institute of the USSR trade union federation. The method takes account of background levels of pollutants. Specific treatment of low-lying sources of emissions (10-20m above the surface) is especially important, because 90% of the sources in industrial zones fall in this category, and the distribution pattern of the emitted pollutants is different from that of high sources.

Farmers' working environment
Viljelijän työympäristö [in Finnish]
Occupational health hazards were measured on 20 farms (cattle, hogs, poultry, grain) in 1980-1982. The ability of occupational health nurses and local agricultural advisers to evaluate health hazards in farm buildings was assessed. The physical factors measured were noise, whole-body vibration, lighting, temperature, humidity and ventilation. Nurses, agricultural advisers and occupational physicians generally made inspection trips without measuring equipment, which meant that they could make qualitative evaluations of dust and illumination levels, but had difficulty evaluating noise, temperature, relative humidity and air velocity; they could not measure atmospheric contaminants (ammonia, methane, formic acid, carbon dioxide) at all.

Bacterial and mycotic flora in the work environment of a foundry
Bakteriální a mykotická flóra v pracovním prostředí slévárny [in Czech]
In grey iron and steel foundries, an average of 93,950 microorganisms was found in 1m3 of air. Mesophilic bacteria predominated over micromycetes and actinomycetes. Microbial contamination ranged from 23,480 organisms/m3 on casting floors to 361,130 per m3 in cellars where moulding mixtures were prepared. 11 species of mesophilic bacteria and 40 species of fungi and yeasts were identified. Microbial contamination came from foundry raw materials and water, and was aggravated by insufficient ventilation. Dust (containing free Si02) that had settled on metal structures at breathing zone level contained the most varied species (8 types of mesophilic bacteria and 61 types of micromycetes). The microorganisms included saprophytic, facultatively pathogenic and toxigenic species.

CIS 84-1016 Possibility of biological indicators as measures of community exposure to organic air contaminants
Possibilités d'utilisation d'indicateurs biologiques pour mesurer l'exposition de la population aux contaminants atmosphériques organiques [in French]
Review of the literature published between 1960 and 1983 on the use of biological monitors (blood, urine, milk, adipose tissue, breath, saliva, nail clippings and hair) to measure body uptake of organic pollutants. Trace elements and organic residues detected, their concentrations and the analytical techniques employed are given for each matrix material. It appears that the use of biological indicators to assess community exposure to airborne contaminants is limited by the complexity of the absorption and metabolic paths followed by each contaminant and the difficulty of distinguishing the contaminant from its matrix.

An aerosol and gas aging line suitable for use in inhalation toxicology research
A gas/aerosol aging line has been designed, tested and successfully used for acute whole-body exposure of rats to atmospheres simulating urban-type mixed oxidant and sulfur plumes after 30min of aging. The line is a nearly-square stainless steel duct with periodic 100-mest stainless steel screens to promote plug flow. The line was tested for uniformity of aging, aerosol losses, and ease of atmosphere control. A close approximation to plug flow could be achieved with excellent atmosphere control. Aerosol losses in the particle size range 0.22-2.0µm were <30% except at aging times ≥ 96min, when significant sedimentation losses occurred for larger particles.

Antimicrobial agents for water-based metalworking fluids
After a review of the microbial problem (anaerobic sulphate-reducing and aerobic bacteria, fungi), in metalworking fluids, the toxicity of biocides (especially alkylamine-formaldehyde condensate biocides), added to control the microbial populations in the fluids, is discussed together with the selection and the use of biocides. Biocides are by definition poisons, the concentrated biocides tend to be highly alkaline and corrosive. But there is continuous exposure to the liquid and aerosol state only after dilution in the metalworking fluid. Approved biocides and their toxicological profiles are listed. Alternative methods for microbial control (heating, radiation) have shortcomings. Although there is no evidence suggesting that exposure to the microorganisms in the metalworking fluid is a hazard, continual exposure should be prevented.

La pollution par les gaz d'échappement automobiles en atmosphčre ouverte et ses effets sur la santé humaine. [in French]
MD thesis. Background information on the composition of motor vehicle exhaust gases (CO, NOx, hydrocarbons, oxidising agents, aldehydes, lead) and variations in their atmospheric concentrations due to various factors (traffic peaks, motor speeds, etc.) is followed by a study of their concentrations in open or semi-enclosed locations (highways, motorways, city streets, tunnels). Analysis of the effects of these gases on human health is based essentially on the results of laboratory experiments and epidemiological surveys, especially of persons occupationally exposed: traffic police, toll gate or tunnel employees, road repair workers, professional and taxi drivers. The results of the toxicological investigation are compared with the maximum tolerance concentrations proposed for each pollutant, and measures are suggested to reduce this pollution. This is followed by a review of French and foreign legislation and considerations on the possibility of having CO and lead poisoning in outdoor workplaces added to the list of occupational diseases giving entitlement to statutory compensation, ending with speculations on future trends in the improvement of existing internal combustion engines and the possible development of a new type of motor causing less pollution.

Occupational profiles of patients with lung cancer compared with those with chronic bronchial obstruction, bronchial asthma or sarcoidosis in the Bern region
Verteilung der Berufe (Berufsmuster) unter Kranken mit Lungenkrebs im Vergleich zu jenen mit chronischer bronchialer Obstruktion, Asthma bronchiale oder Sarkoidose in der Region Bern [in German]
Results of computer analysis of the histories of 4,802 subjects with respiratory disease examined in 1974-1977. Selection criteria were: arduousness of physical work and occupational exposure to respiratory hazards and climatic factors; chronic bronchial obstruction; asthma; histologically confirmed lung cancer; sarcoidosis. The part played by cigar and pipe smoking in lung cancer development was established in an earlier study. Results: in office workers, sarcoidosis and asthma above all were found, while lung cancer was rare; in metallurgical, chemical and plastics industry workers, there was no abnormal incidence of lung cancer related to air pollution levels; lung cancer was more frequent in workers in the open air (building industry, agriculture), probably as a result of air pollution due to mechanisation.

Study of microbial pollution of cutting fluids - Efficacy of a number of disinfectants on contaminating organisms
Etude de la pollution microbienne des fluides d'usinage - Efficacité d'une série de désinfectants sur les germes contaminants. [in French]
Oil emulsions used as cutting fluids are particularly liable to massive microbial contamination, undesirable for technical and health reasons (oil acne, dermatosis hazard). The authors identified the contaminating bacteria (pseudomonadaceae, enterobateriaceae, etc.) and evaluated the action of 13 commercial disinfectants on them (effects on growth rate of a mixed culture of micro-organisms). With tests of this kind, efficient bactericidal products compatible with the chemical properties of a cutting fluid can be selected. However, some disinfectants (phenols and their derivatives, etc.) may cause skin irritation or sensitisation; hence the importance of not exceeding the required amount of disinfectant.

Farmer's lung in a group of Scottish dairy farms.
The microbiology of the air of byres and bruising sheds and of hay, grain and dust from bruising machines was studied at 12 dairy farms, 7 of which had one known case of farmer's lung disease (FLD) and 5 farms no known cases. Concentrations of mesophilic organisms and of thermotolerant and thermophilic fungi were similar but concentrations of thermophilic actinomycetes and bacteria, especially M. faeni, were higher on FLD farms. Results of serological studies are given.

Carbon monoxide pollution inside a moving car
Pollution par le monoxyde de carbone ŕ l'intérieur d'une voiture en circulation. [in French]
Study of parameters which may influence CO levels to which professional drivers (taxi drivers, sales representatives, etc.) and commuters, who are obliged to drive in urban areas, may be exposed inside their vehicle, and of toxicological aspects of repeated exposure of this kind. At different times in a given 24h period (night, off-peak or peak traffic hours) overall CO exposure may vary in a ratio of 1:6 between off-peak and peak traffic times, and 1:60 between night hours and peak traffic period. Concentrations inside the vehicle were equal to or higher than those measured on the roadside. Driving during the peak period causes carboxyhaemoglobin levels of 1.7% (minimum) and 2.4% or over if the driver was previously exposed to CO pollution; at these levels sensorimotor imbalance may result if exposure is repetitive.

Dynamic lung function changes following long-term work in polluted environments.
Results of spirometric tests in 10 young and 10 middle-aged men exposed for 4h to a) filtered air; b) 50ppm of CO in filtered air; c) 0.24ppm peroxyacetylnitrate in filtered air; and d) 50ppm of CO and 0.24ppm of peroxyacetylnitrate in filtered air, at 2 temperature levels, while performing submaximal work: the FVC of the younger subjects was reduced by peroxyacetylnitrate in filtered air combined with thermal stress; older subjects showed no significant changes. Exercise alone changed the FEV1.0/FVC% in all subjects. Oxidant-type pollutants appear to act on the dependent regions of the lung, while exercise appeared to stimulate the lung during forceful expiration.

Decision and estimation procedures for air contaminants.
The problem is discussed of enforcing average exposure standards for air pollutants in industrial environments. A statistical test was devised to decide whether the average concentration of a contaminant exceeds a certain threshold. The test is based on a number of samples of the contaminant, assumed to be log-normally distributed. A simple graphic procedure makes the test practical for field use. The estimation of the average level of contaminant was also discussed.

Air pollution in the working environment and occupational disease
Pollution de l'air en milieu industriel et maladies professionnelles. [in French]
A great many occupational diseases are due to workplace air pollution. The absorption and localisation of gases and vapours depend on factors which are briefly described: deposition of particles is related to their physical properties, the shape of the respiratory airways, and lung ventilation parameters. Various defence mechanisms also play a role. Illustrative examples are given of occupational diseases caused by solvents, carbon monoxide, metals, dusts (silica, asbestos, hard metals), allergens and carcinogens. The importance of prevention is emphasised.

Attempt at a mathematical description of the relations between certain physical parameters characterising the atmosphere of production premises
Próba matematycznego opisania zależności pomiędzy niektórymi parametrami fizycznymi charakteryzującymi środowisko powietrzne w promieszczeniach produkcyjnych [in Polish]
Description of 2 mathematical models used to determine the distribution of air pollutants, an indispensable parameter for the design of an appropriate ventilation system. The first model, in the form of a complex polynomial based on spatial network theory, takes account of the interaction between the different emission sources. The second, a system of differential equations resulting in an algorithm, expresses the influence of the air movement due to the ventilation on the distribution of dust concentration in a closed space. The results obtained by applying these models confirm the possibility of a mathematical representation of the phenomena that are involved in the propagation of pollutants in the air of production workplaces.
