Health hazards of fire fighters: Exposure assessment
To assess the types and levels of exposure encountered by firefighters, members of the Buffalo Fire Department (USA) were monitored during firefighting activities with personal, portable, ambient environmental sampling devices. The results indicate that firefighters are frequently exposed to significant concentrations of hazardous materials including carbon monoxide, benzene, sulfur dioxide, hydrogen cyanide, aldehydes, hydrogen chloride, dichlorofluoromethane, and particulates. In many cases of the worst exposure to these materials, respiratory protective equipment was not used owing to the visual impression of low smoke intensity. Many of these materials have been implicated in cardiovascular, respiratory, or neoplastic diseases. This may provide an explanation for the alleged increased risk of developing such diseases among firefighters.

Descent into manholes - The air in manholes may be deadly
Einsteigen in Schächte - Die Luft im Schacht kann tödlich sein [en alemán]
Carbon dioxide, methane and hydrogen sulfide are the most hazardous gases that may occur in manholes. Two examples are used to illustrate that natural ventilation may not suffice to remove all toxic concentrations. Manholes must be supplied with fresh air forced all the way to the bottom. In addition, measurements of the CO₂, CH₄ and O₂ concentrations are necessary prior to entry.

Incidence of laryngeal cancer and exposure to acid mists
To determine the relation between exposure to acid mist and laryngeal cancer, the smoking habits, drinking habits, and incidence of laryngeal cancer among 879 male steelworkers exposed to acid mists during pickling operations were ascertained. These men had an average duration of exposure of 9.5 years. Exposures to sulfuric acid in the 1970s averaged about 0.2mg/m³, and earlier exposures were probably similar. Nine workers with laryngeal cancer were identified. Using data from national surveys of cancer incidence as referent rates, 3.44 laryngeal cancers would have been expected. Excess smoking by the exposed cohort compared with the United States population resulted in an upward adjustment of the expected number of cases of laryngeal cancer to 3.92. The standardised incidence rate ratio for laryngeal cancer was 2.30 (9/3.92). The finding of excess laryngeal cancer in this cohort is consistent with four other studies published since 1981.

Occupational asthma in a mineral analysis laboratory
An epidemic of symptoms suggestive of occupational asthma in workers in a mineral analysis laboratory necessitating exposure to vapours of hydrochloric, hydrofluoric, nitric, perchloric, and sulfuric acid solutions was investigated. Variable airflow obstruction was confirmed by serial measurement of FEV₁ in 2 subjects who showed 18% and 22% falls in FEV₁ during a workshift. Of a workforce of 21 laboratory staff, 20 took part in a study of ventilatory capacity and bronchial reactivity. All but one subject had normal ventilatory capacity but 5 had bronchial hyperreactivity. Four of the 5 with hyperreactivity had a history of chest tightness at work. In 2 of 4 subjects with hyperreactivity, bronchial reactivity has returned to normal after 205 and 376 days away from work, suggesting that bronchial inflammation resulted from occupational exposure to acid vapours.

Mortality in the US rayon industry
A retrospective cohort study was undertaken of the mortality of men exposed to carbon disulfide in the US rayon industry. The cohort consisted of 10,418 men employed between 1957 and 1979. Total mortality in the group was slightly lower than that of the comparable US population. There was no significant difference in overall mortality between the 4,448 employees who had held jobs with the greatest potential for exposure to carbon disulfide and the 3,311 workers who had no exposure. However, there was an excess of deaths from arteriosclerotic heart disease among the potentially most heavily exposed (242 deaths observed, 195.6 expected). An excess of deaths from suicide (29 observed, 18.8 expected) was seen in only 1 of the 4 plants.

Disturbed iron metabolism among workers exposed to organic sulfides in a pulp plant
Eighteen workers exposed to sulfides at a pulp and paper plant were examined and compared with individually matched non-exposed referents. The exposure levels of methylmercaptan, dimethylsulfide, and dimethyldisulfide were low. However, 5 subjects were exposed to high levels of short duration, and their data were analysed separately. The activity of the enzymes delta-aminolevulinic acid synthase and heme synthase in reticulocytes, characteristics of the erythrocytes, and the iron status were analysed. A minor decrease, not statistically significant, was observed for the enzymes among the 5 highly exposed subjects. However, the concentrations of iron and transferrin were elevated and the concentration of ferritin was low in comparison with the corresponding levels of the referents. This combination will not occur spontaneously. A previous study indicated that sulfides may inhibit heme synthesis, and the present study suggests that they may also disturb iron metabolism.

Using a modified water-glass binder to improve working conditions of casting knockout workers
Primenenie modificirovannogo židkostekol'nogo svjazujuščego v celjah ulučšenija uslovij truda vybivščikov [en ruso]
The working environment in a casting knockout operation was studied in order to improve the safety and health of workers. The results were computer processed and a mathematical model was developed. By way of improvement it was suggested that the additives ammonium sulfate and sodium sulfite be used, which improve the strength of water-glass (sodium silicate) mixtures and facilitate knocking out. This measure decreases the physical work load of the operation and helps to bring down dust levels in the workplace air.

The relative sensitivity of the human eye and lung to irritant gases
Various concentrations of irritant gases were applied to the eyes of subjects through close-fitting goggles and, in separate experiments, to the lungs via a mouthpiece. Eye response was detected subjectively, lung response was measured objectively by plethysmograph and the threshold concentrations for no-response were determined. For a number of gases tested (sulphur dioxide, ammonia, butan-2-one, pentan-2-one, pentan-3-one, 3 methyl butan-2-one, formaldehyde and acrolein), the threshold concentrations for the eyes was about 1.5 times that for the lungs. Other irritants, however, can be specific for certain organs.

Several absorber solutions were tested for their suitability for air sampling. A 0.01N solution of sulfuric acid performed best. As the solution also traps methanol and ammonia, it is especially useful for monitoring air quality in carbamide resin plants or in fibreboard plants, where formaldehyde, methanol and ammonia are all liberated simultaneously.

Possible toxic metal exposure of prehistoric bronze workers
An attempt was made to assess the possible occupational exposure to arsenic, lead, and mercury during the Bronze Age. Archaeological, metallurgical, and historical evidence is combined to form a picture of the potential toxic hazards. In the case of arsenic, a definite picture emerges of the effect of toxicity as a useful material is abandoned for health reasons on discovery of an acceptable alternative.

A non-toxic diffusional dosimeter for sulfur dioxide
The method combined the use of a diffusional dosimeter and a relatively non-toxic buffered formaldehyde absorbing solution. The dosimeter gave reproducible results using two lots of single-backed dimethylsilicone membranes; sampling times from 1 to 7hr; sampling temperatures from 25°C to 38°C; and at face velocities from 0-600ft/min (0-3m/s). Concentrations as low as 0.05ppm were determined over a maximum sampling time of 7hr, yielding a sensitivity better than 0.35ppm.hr. Fluctuating concentrations from 0.5, 1.0 or 2.0ppm background to 10.0ppm for 1/2hr resulted in no significant error.

Baritosis - A case report
Bariumu-hai (Baritosis) ni tsuite - Jikenrei o chūshin ni [en japonés]
The patient had worked for 5 years in a factory producing purified barium sulfate powder for medical use. His chest X-ray film was characterised by diffuse fine nodulation of a peculiar density, but he was free from any symptom. His lung function remained within the normal range. Transbronchial lung biopsy was performed. On light microscopy, the specimen consisted of pulmonary alveolar structures with a number of macrophages which contained pale yellow or brown pigments and birefringent particles in the cytoplasm. There was minimal fibrosis without fibrotic nodules. Electron microscopy showed the presence of barium and sulfur in the lung tissue.

Basis for a particle size-selective TLV for sulfuric acid aerosols
The occupational exposure limit for sulfuric acid (H₂SO₄) aerosol in the US is 1mg/m³, with no restrictions as to droplet size. A review of the literature shows that there are two different responses to inhaled H₂SO₄ which need to be considered in the selection of a threshold limit value (TLV) or other occupational exposure limit. One is a reflex bronchoconstriction caused by the deposition of droplets in the larger lung airways. The other is the development and progression of chronic bronchitis caused by repeated daily exposures to droplets depositing in the central and more distal conductive airways of the lung. Since the target region for both effects is the tracheobronchial tree, a particle size-selective TLV (PSS-TLV) should be expressed in terms of thoracic particulate mass (TPM). The mass concentration limit for H₂SO₄ TPM should be much lower than the current TLV. A TPM-TLV of 100µg/m³ should protect nearly all workers from adverse effects.

Some effects of cigarette smoking, arsenic, and SO₂ on mortality among US copper smelter workers
This is a report on the 1949-1980 mortality experience of 6,078 white male workers who worked for at least 3yrs between 1 January 1946 and 31 December 1976 at 1 or more of 8 copper smelters. The completeness of the cohort was verified statistically, and worker exposures to arsenic, SO₂, dust, nickel, cadmium, and lead were estimated from retrospective surveys. By using internal controls, a dose-response relationship for lung cancer was observed with exposure to arsenic and SO₂. When cigarette smoking data were included with arsenic and SO₂ exposure data in a nested case-control analysis, only smoking and arsenic were statistically significant factors. The arsenic-lung cancer relationship was confined to a single smelter where the raw materials had a high arsenic content. In the remaining smelters, mortality for all causes of death and for all cancer was not high based on comparisons with national, state, and local rates.

Exposure to carbon disulphide and ischaemic heart disease in a viscose rayon factory
The cohort of viscose rayon workers previously followed from 1950-1964 has been reconstructed and followed up to the end of 1982. The pattern of mortality at ages 45-64 for the extended period 1950-1982 is similar to that described for 1950-1964. Spinners, the workers most heavily exposed to carbon disulfide (CS₂), have a significantly higher mortality from all causes than the least exposed group. The excess mortality is largely accounted for by ischaemic heart disease (IHD) for which spinners have an SMR of 172. When mortality is related to an exposure score in the same group, both all-cause and IHD mortality increase with increasing exposure level. When this analysis is repeated covering all ages, these trends become much less pronounced and only that for IHD remains significant. Over the age of 65 there is a tendency for mortality to decline with increasing exposure. This is contrary to expectation under the usual hypothesis that CS₂ promotes atherosclerosis. Instead it suggests that CS₂ has some type of reversible, direct cardiotoxic or thrombotic effect. IHD and total mortality show highly significant trends with exposure among current workers but no such trends among workers who have left the industry.

Respiratory cancer among soap production workers
Employment in the soap production industry in Italy has entailed some exposure to sulfuric acid vapours and nickel dusts, both agents under suspicion of being carcinogenic for the respiratory tract. A mortality study, together with an incidence study for laryngeal cancer, has been conducted among 361 men with a minimum employment of one year in soap production. Mortality from all causes was lower than expected, but lung cancer and laryngeal cancer deaths were increased, although without statistical significance. 5 new laryngeal cancer cases were detected during the study period, while about one was expected. All the men with respiratory cancer had been working for several years, and the latency time was greater than 10 years. Even though the mechanism of a causal link is difficult to assess, the possibility of a carcinogenic effect of sulfuric acid is suggested.

Combined effect of ozone and sulfuric acid on pulmonary function in man
Nine young men were exposed to 0.25ppm ozone (O₃), 1200-1600µg/m³ sulfuric acid aerosol (H₂SO₄), and a combination of O₃ and H₂SO₄. During the 2-hour exposures, the subjects exercised (ventilation = 30L/min) 3 times for 20min each. Air temperature was 35°C and relative humidity 83%. If a reaction between the combination of O₃ and H₂SO₄ and pulmonary function occurred, pulmonary function responses may have been anticipated following the combination exposure, but no significant changes were seen. The combination of ozone and sulfuric acid aerosol at levels in excess of TLV levels do not cause pulmonary dysfunction.

Sodium sulfide is a local irritant, is gonadotoxic, and it disturbs central nervous system function and protein and lipid metabolism on chronic inhalation exposure. Workers exposed to sodium sulfide and some reagents used in flotation enrichment of copper-molybdenic ores developed disorders of the upper respiratory tract, gastrointestinal tract and skin. Mechanisation of certain operations and use of respirators is recommended. MAC for sodium sulfide in workplace air of 0.2mg/m³ has been established.
