Environmental illness
Six letters to the editor commenting on an article by Black D.W. and al. (Environmental illness: a controlled study of 26 subjects with '20th century disease', see CIS 92-347). The letter by McCampbell A. describes an outbreak of recurrent upper respiratory tract infections and fatigue reported among staff at a high school in California. In this case, ventilation was found to be inadequate and the hazy and foul smelling air was due in part to poorly maintained air filters and gasoline engine exhaust near the fresh-air intake. Symptoms and clinical characteristics of this outbreak were consistent with a diagnosis of sinusitis. Since sinusitis is well recognised as occurring after exposure to inhaled irritants and causes sypmtoms of environmental illness, the writer considers such exposure a possible cause of the syndrome. The other letters and the reply by Black D.W. discuss the role of psychiatric disease in the occurrence of 'environmental illness'.

The environment and the lung: Changing perspectives
This paper discusses the changing focus across the century of public health concern and research in regard to environmental lung diseases. Broad groups of environmental agents that produce lung disease are considered along with the currently available evidence for several air pollutants selected to be illustrative of the changing emphasis of concern. These include asbestos, radon, environmental tobacco smoke, acidic aerosols, sulfur dioxide and oxidant pollutants, including ozone and nitrogen dioxide. In the persistent concerns about adverse effects of polluted air on the lung, the focus has shifted from avoiding clinical disease among highly exposed individuals to protecting the population from an unacceptable burden of risk.

Pollution at coke works
Pollution dans les cokeries [in French]
Report of investigations into the measurement of polycyclic aromatic hydrocarbons (PAH) and bezene, toluene and xylene (BTX) in and around coke workers. PAH emission from 7 sources on a coking plant were documented and on old coke oven batteries the 2 major sources were shown to be the coke oven door and the charge hole lids; the level of emissions from modern plants with self-sealing doors was significantly lower than from older plants. The highest concentrations of BTX were found on the by-product plant, although the highest yields in terms of weight per tonne of coke produced were associated with the battery. Details are given of the sampling and analysis methods used.

Estimation and control measures of indoor air pollution by smoking
Kitsuen ni yoru shitsunai kūki osen to sono taisaku [in Japanese]
The quantity of air pollutants generated by smoking in office rooms was estimated and measures to control air pollution were examined. Experimentally, a cigarette generated 15mg of particulate matter, 50mL of CO and 1mL of NO. The concentration of particulate matter generated varied depending on smoking situations and ventilation in the room concerned. In a series of rooms served by the same ventilation system, tobacco smoke generated in a smoking office invaded non-smoking offices through the ventilation system. Tobacco smoke accounted for 4-74% of the particulate matter in the air supplied by the ventilation system. The relative effectiveness of three methods of controlling air pollution due to smoking was demonstrated: complete banning of smoking; separation of smoking sites or time; and limitation on the number of persons smoking at any one time.

Respiratory symptoms and lung function of aluminium potroom workers
The association of occupational exposure with respiratory disease and lung function was examined in a cross-sectional study of 1805 aluminium potroom workers. Work-related asthmatic symptoms occurred in 15% of the workers with an exposure of 10 years or more and in 8% of the workers who had been employed less than 5 years. In a multiple logistic regression analysis an odds ratio (OR) of 3.4 (95% confidence interval (95% CI 2.1-5.8) for work-related asthmatic symptoms was estimated for long versus short duration of employment. Airflow limitation was also significantly related to years of exposure (OR 2.6, 95% CI 1.7-3.9). Current occupational exposure and the occurrence of respiratory symptoms were not significantly associated. The results suggest that exposure to air pollutants in the primary aluminium industry may lead to the development of asthmatic symptoms, as well as to reduced respiratory function.

Laser printers and air contaminants - A review
Laserskrivare och luftföroreningar - En översikt [in Swedish]
Laser printers generate ozone and other contaminants; they also emit heat capable of affecting the temperature in a room. The amount of ozone generated varies with printer size and frequency of use. Concentrations around the TLV could arise when a printer is heavily used in a room with inadequate ventilation. Corona discharges, toner particles, vapours from toner particles and dust from paper are other sources of air contaminants. Health risks could develop in a room with poor ventilation. A large printer might even pose a health hazard in rooms with good ventilation. A laser printer subjected to heavy use should be placed in a separate room and preferably be equipped with a local exhaust.

Reentrainment of air pollutants in rotary heat exchangers
Återföring av luftföroreningar i roterande värmeväxlare [in Swedish]
Six exchangers, installed in office buildings in the northern part of Sweden, were included in this study. Formaldehyde in the indoor air was used as a monitor pollutant and was sampled at 4 positions around the rotor, before and after passage of the rotor, in both the exhaust and supply air streams. Sampling of homogeneous air in the ducts was performed simultaneously with 2,4-dinitrophenylhydrazine-coated glass fibre filters. The analysis of formaldehyde was made by high performance liquid chromatography. The reentrainment of formaldehyde was 1-9%.

The effect of air cleaners on tobacco smoke - Part II. Long-term test and complementary measurements
Luftrenares effekt på tobaksrök - Del II. Långtidsprov och kompletterande mätningar [in Swedish]
A long-term test was conducted by loading 3 different room air cleaners with smoke from 20, 200, 400, 600 and 800 cigarettes and measuring their ability to remove gases and particles from the contaminated air. The measurements covered particles from 0.01 to 7.5 microns and gases: carbon monoxide, ammonia, formaldehyde, nitric oxide, nitrogen dioxide, hydrocarbons and hydrogen cyanide. The cleaning efficiencies for particles were approximately constant, while the cleaning efficiencies for the gases decreased considerably with increasing smoke load. The report also describes measurements of the ability of the air cleaners to remove acrolein, the pH of the activated charcoal in the air cleaners, the emission of gases and particles from room air cleaners contaminated by cigarette smoke, and from smoke deposition on room surfaces. The first part of this study was published as Arbete och hälsa 1987:28 (CIS 89-1962).

Combined effects of sound, climate and air pollutants on noise induced hearing loss
In a laboratory experiment, 10 subjects were exposed to various sound loads at air temperatures of 24°C and 35°C. As expected, the greatest threshold shifts occurred at maximum sound and climate loads. A field study was also carried out to investigate permanent hearing loss in groups of welders and machinery and plant assembly workers exposed to a combination of noise and carbon monoxide. Welders suffered hearing damage when the noise limit for hearing impairment was scarcely exceeded, while the risk was relatively lower for the assembly workers with comparatively higher noise levels and lower carbon monoxide exposure. Results therefore indicate a relationship between combined noise and carbon monoxide exposure and risk of hearing damage.

Ocular infections and the industrial use of microscopes
A cluster of ocular infections occurred in one area of a computer fabrication facility that relied on the use of industrial microscopes. A questionnaire was administered to all employees in this area. Microscope oculars were cultured and compared with control microscopes from a nonindustrial setting. Risk of infection was correlated with the number of hours of microscope use per day and subjective indicators of cleanliness. Bacterial cultures confirmed increased colony counts in industrial oculars compared with control oculars. Hygienic practices were instituted similar to those employed in medical settings. No further outbreaks of conjunctivities have been reported in a 1-year follow-up.

An outbreak of infectious conjunctivitis spread by microscopes
Among the potential occupational hazards of microscope use is the transmission of infectious agents among employees. A large (145 cases) and costly ($647 000) epidemic of viral conjunctivitis in a microelectronics factory is reported. Spread of the illness appeared to be through sharing of microscopes among employees. Routine handwashing instructions and safety glasses failed to prevent spread of the epidemic. Mandatory screening prior to work and temporary plant shut-down were finally successful. Efforts to control this outbreak and recommendations to prevent similar epidemics in other workplaces are discussed.

Characterization of exposure to molds and actinomycetes in agricultural dust by scanning electron microscopy, fluorescence microscopy and the culture method
Air samples from 79 farms with 105 to 1011 microorganisms/m3 were analysed by scanning electron microscopy (SEM), fluorescence microscopy (FM) and the culture method. The total concentration of microorganisms (particularly actinomycetes) was underestimated when assessed as colony-forming units (cfu). The average cfu count was one-sixth of the total count according to SEM or FM, and there was considerable individual variability. This finding can be partly explained by the aggregation of spores. Single spores accounted for 2-65% of all spores in 35 samples. There was an average of three spores/particle, and 93 (range 67-100) % of the spores were single or in aggregates of respirable size. Aggregation was more pronounced for actinomycetes and at high spore counts. Actinomycetes and bacteria could not be distinguished by FM. Bacteria (other than actinomycetes) were not detected by SEM, yet the total count of microorganisms was similar for FM and SEM. Most particles were spores from actinomycetes and fungi of the genera Aspergillus or Pencillium.

Association between acid fumes in the work environment and dental erosion
A sample of 186 workers was drawn from four factories. Among the 157 dentulous (having natural teeth) participants, 76 were working in departments containing acid fumes, and 81 had never worked under such conditions and were used as referents. Of the acid workers 18.4% had one or more teeth with erosion, and the corresponding figure for the referents was 8.6%. With a longer duration of exposure the proportion of subjects with erosion increased. The acid workers had more teeth with erosion than the referents, especially upper anterior teeth. The findings suggest that even today exposure to inorganic acid fumes from the work environment may increase the erosion of teeth, especialy of the upper anterior teeth, which are not continuously protected by saliva and the lips.

Specific rates of emission of harmful substances into the atmosphere during the production of rubber shoe soles
Udel'nye vybrosy vrednyh veščestv v atmosferu pri proizvodstve reziny dlja niza obuvi [in Russian]
Specific emission rates were calculated on the basis of material balances for each of the 6 operations in sole manufacture; the results are presented in a table. The largest quantity of gaseous pollutants are emitted during vulcanisation (85-95% of the total emissions for the process). Of the 4 types of sole produced, coloured porous rubber gave the largest amounts of gas, black solid rubber the smallest. The average composition of the gaseous emissions was: 1.2% aldehydes, 28% aromatic hydrocarbons (of which 2% styrene), 1.5% amines, 7% naphthenes, 8% normal and iso-paraffins (3-7 carbons), 7.5% normal and iso-olefins, 16% for 8-14-carbon paraffins, 12% for 8-14-carbon olefins, and 20.3% unidentified. An equation was derived for predicting the quantity of emissions from the amounts of natural rubber, blowing agent, regenerated rubber and mineral filler used in the process.

Occupation and death due to pulmonary emphysema
Dödlighet i emfysem bland yrkesarbetande män [in Swedish]
This study is a linkage of the 1960 National Census of Sweden and the Causes of Death Register from 1961-1970 in order to investigate the correlation between occupation and death due to pulmonary emphysema. The study only comprised men born 1901-1920, and smoking habits in different occupational groups were taken into account. Self-employed persons and supervisors in farming, forestry and market gardening had the highest incidence of deaths due to pulmonary emphysema. This excess risk is significant, even after the performed number of comparisons is taken into account. A significant correlation was found between estimated exposure to air pollutants and mortality due to emphysema in men born 1911-1920.

Hygiene and psycho-social characteristics of the work of laboratory workers at research institutes
Higiena i psiho-socialna harakteristika na truda na laboratorni rabotnici v naučni instituti [in Bulgarian]
The study covered toxicological, chemical, clinical, histomorphological, phytochemical, microbiological, and other laboratories. Microbial pollution of air and the concentrations of chemical compounds were measured. Microbiological data showed a seasonal dependence. Alcohols were found in the air, as well as nitrogen oxides and organic solvents at concentrations considerably above their MACs. The psycho-social study, carried out by a questionnaire method, showed that mental fatigue was more common than physical fatigue. Complaints of all kinds of fatigue were more common among the technicians (all women) than among the more highly trained specialists (men and women). Specialist women reported fatigue more often than specialist men. Better control of airborne contaminants and better organisation of work are recommended.

Industrial fluoride pollution in the metallurgical industry in China
The hazard of airborne fluoride pollution in 63 plants in the metallurgical industry in China was studied. Fluoride injuries in plant workers were more severe in the electrolysis works in aluminium plants and iron smelters. The incidence of fluorosis among workers was 3.2%, and the symptoms were systemic. For diagnosis, both the effects of airborne fluoride pollution and fluoride content in water must be considered, because some workers come from areas where fluoride content in water is high and fluorosis is endemic. Anti-air-pollution devices are needed to reduce the hazard of industrial fluoride pollution.

A study of the relationship between airborne contaminants and environmental factors in Dutch swine confinement buildings
A total of 171 swine confinement buildings were studied to determine the concentrations of airborne total dust and dust with an average diameter ≤8.5µm, total and gram-negative bacteria, bacterial endotoxin and ammonia. The concentrations of these airborne contaminants then were correlated statistically to environmental factors such as feeding practices, number of animals and ventilation parameters. Airborne dust, endotoxin, bacteria and ammonia are commonly at levels where health effects have been observed in other studies. Correlation of these airborne contaminants with environmental factors showed that while ventilation is an important criterion there are farming practices that significantly contribute to the levels of airborne contaminants currently found. Pearson correlations indicate a number of important criteria that the industrial hygienist should measure when faced with problems in agricultural confinement buildings.

Microscopes and ocular infections
Microbial assays of industrial microscope eyepieces were conducted and pathogenic staphylococcus aureus was identified among the microorganisms. It appears that direct contact with microscope eyepieces provides a potentially significant route of transmission of bacterial and viral infections. A questionnaire was distributed to a first and second shift manufacturing operation to assess the incidence of ocular infections. There was a statistically significant incidence of sites and conjunctivitis that was 8.3 times that of a control group. An ultraviolet disinfection process was evaluated; it was rapid and emission-free and there were no residual chemical biocides.

Concentrations of 20 volatile organic compounds in the air and drinking water of 350 residents of New Jersey compared with concentrations in their exhaled breath
Twenty volatile organic compounds were measured in the personal air and drinking water of 350 New Jersey (USA) residents in the fall of 1981. Two consecutive 12-hour integrated personal air samples and 2 tap water samples were collected from each participant. At the end of the 24-hour monitoring period, each participant supplied a sample of exhaled breath. Simultaneous outdoor samples were collected in 100 residential locations in 2 cities. Eleven compounds were present much of the time in air, but only 4 (the trihalomethanes) in water; wide ranges of exposures (3-4 orders of magnitude) were noted for most compounds. Ten of 11 compounds displayed significant correlations between air exposures and breath concentrations; the 11th (chloroform) was correlated with drinking water exposures. It was concluded that breath measurements are a feasible, cost-effective, and highly sensitive way to determine environmental and occupational exposures to volatile organic compounds.

Study of the toxic substances formed in the oxo process
Izučenie toksičnyh veščestv, obrazujuščihsja v processe oksosinteza [in Russian]
In the oxo process, olefins are reacted with carbon monoxide and hydrogen to yield alcohols; aldehydes are intermediate reaction products. Various volatile by-products may also be formed, so that workplace air can be contaminated by a wide range of substances. To identify and quantitate these contaminants, air was sampled by being drawn through a glass tube packed with Tenax sorbent. The material collected was desorbed onto a glass capillary gas-chromatography column coated with SE30. The gas chromatograph was coupled to a mass spectrometer. 165 organic compounds were identified. They included saturated, unsaturated and aromatic hydrocarbons, terpenes, halogenated hydrocarbons, nitriles, thiocyanates, sulfides, alcohols, ethers, aldehydes and ketones.
