Combined effect of hydrogen fluoride and sulfur dioxide on the white rat
Kombinirovannoe dejstvie ftoristogo vodoroda i sernistogo angidrida na organizm belyh krys [in Russian]
Rats were exposed to hydrogen fluoride (HF), sulfur dioxide (SO2) or a mixture of the two at concentrations equivalent to 1/10, 1/4, 1/2 or 1 time the USSR MACs (0.5 and 10mg/m3, respectively). The albumin and globulin content of their blood was analysed by electrophoresis after 4 months of exposure for each working day. At 1/10 of the MAC, mixtures produced effects similar to those of HF alone; at higher concentrations, the effect of SO2 became more prominent. Changes in the relative proportions of the classes of serum proteins were more significant than changes in total protein concentration.

Experimental study on the atherogenic effect of carbon disulfide
Eksperimentalno proučvane na aterogennija efekt na serovăgleroda [in Bulgarian]
Carbon disulfide (CS2) administration at 10 and 50mg/m3 was followed by electrophoresis of serum proteins and qualitative and quantitative analysis of fibre structure in the myocardium and aorta of albino rats on a 30-day atherogenic diet. The combination of CS2 with the atherogenic factor intensified the changes in the cardiovascular system and serum proteins observed with the individual effect of both factors. Intoxication and decreased animal survival as well as alterations in serum, myocardium and aorta occurred at a concentration of 10mg/m3. Thus, CS2 has an atherogenic effect.

Mortality from heart disease among workers exposed to solvents
A survivorship analysis was used to compare the cardiovascular disease mortality in a cohort of 1,282 white male workers exposed and non-exposed to solvents in a rubber and tyre manufacturing plant during a 15-year follow-up period. Detailed exposure estimates for 25 solvents were available. The known association between carbon disulfide exposure and ischaemic heart disease (IHD) was apparent among these workers, and 2 other solvents, ethanol and phenol, were also significant predictors of IHD. Solvents other than carbon disulfide may cause atherosclerotic disease.

Disulfiram test application to workers exposed to carbon disulfide
Prilagane na disulfiramov test pri rabotnici, exponirani na serovăglerod [in Bulgarian]
The disulfiram test was applied to 50 workers from a chemical plant for the production of artificial fibres, 30 of them exposed to carbon disulfide (CS2) at concentrations close to or over the MAC and 20 without contact with toxic substances. After the oral intake of 0.5g disulfiram (Antabuse, Anticol), the circadian fluctuation in the excretion of thiourea and diethyldithiocarbamates was determined. In parallel, an iodine-azide exposure test was performed. There was a decreased excretion of thiourea and a smaller number of positive iodine-azide reactions in the exposed workers. No significant discrepancies were found in the excreted quantities of diethyldithiocarbamate in the urine of control and exposed workers. The disulfiram test may be useful for the determination of individual sensitivity to CS2.

Cross-sectional study of respiratory symptoms and pulmonary functions in rayon textile workers with special reference to H2S exposure
The study was conducted in 18 viscose rayon plants in Japan. Hydrogen sulfide (H2S) exposure was determined by personal passive dosimetry and FEV was measured before and after an 8-hour shift in 30 matched pairs of exposed and non-exposed workers. Exposure averaged 3ppm (0.3-7.8ppm) for the exposed workers and 0.1ppm for the controls. No significant difference in 8-hour pulmonary function test was observed, and no significant correlation between individual pulmonary function changes and individual H2S exposure was obtained. FEV indices in one group of 324 workers were better in exposed non-smokers than in non-exposed non-smokers. A questionnaire survey of 2379 exposed workers and 2968 non-exposed workers revealed a correlation of respiratory symptoms with smoking habits, but not with work history in rayon plants.

A fluorescein angiographic study on carbon disulfide retinopathy among workers in viscose rayon factories
Fluorescein fundus angiograms were analysed in 143 workers exposed to CS2 and 40 control subjects. The incidene of retinal abnormalities (saccular microaneurysms, ellipsoidal micro-aneurysms and loop formations of small vessels, and atrophic/degenerative changes in the pigmentary epithelium) was significantly higher in the workers exposed to CS2. The effects were correlated with exposure. Chronic CS2 exposure affects not only the retinal vasculature but also the retina itself.

Carbon disulfide absorption by inhalation as a function of physical workload
Zur inhalativen Aufnahme von Schwefelkohlenstoff - Untersuchungen zur CS2-Aufnahme bei dosierter dynamischer Belastung [in German]
Research methods and results are described for CS2 absorption at different levels of physical effort and exposure. Physical work stimulates CS2 absorption, while the respiratory flow determines the absorbed dose relative to the concentration. Therefore physical workload is of prime importance for the rate of absorption. It should be considered during the establishment of permissible concentration levels in the workplace.

Serum gonadotropins and testosterone in men occupationally exposed to carbon disulfide
69 men exposed to CS2 in viscose rayon production and 22 non-exposed controls were studied. Duration of exposure was 1-36 years. Follicle-stimulating hormone (FSH) levels were significantly higher in the exposed men, that of sex-hormone binding globulin (SHBG) significantly lower. Luteinising hormone (LH) values were significantly higher in 24-31 year-old exposed men than similar-aged controls. SHBG, FSH, LH and free testosterone index were significantly different from controls in men aged <39 years exposed to CS2 for 1-9 years, whereas when exposure was ≥10 years, only FSH levels were significantly different in this age group from controls. In men aged ≥40 years after 10 years of exposure, only FSH and LH were significantly higher. Levels of CS2 well below the TLV of 30mg/m3 may affect the hormonal balance in the pituitary-gonadal axis, suggesting an increased risk of latent primary gonadal insufficiency.

A tube diffusion dosimeter for sulfur dioxide
The design of this dosimeter incorporates a tube diffusion element, liquid absorption reservoir (0.08M tetrachloromercurate) and a porous plastic mass transfer element. Laboratory and field tests confirmed that the dosimeter was reliable for SO2 concentrations between 2.5 and 15ppm. Exposed dosimeters require refrigeration and analysis within 24h. A colorimetric method (NIOSH method 160) is used for analysis. Estimated overall accuracy for the method is approximately ±10%.

CIS 84-1315 Hydrogen sulfide
Dihydrogensulfid [in Swedish]
Criteria document in the form of a review of the world literature on hydrogen sulfide. The toxic effects of the gas on the central nervous system are due to inhibition of the terminal oxidase of the mitochondrial electron transport system. The gas is also an irritant, producing pulmonary oedema and conjunctival damage at concentrations below those affecting the central nervous system. As the irritation is a warning of the presence of hydrogen sulfide, threshold concentrations for irritation should be taken into consideration in establishing an occupational exposure limit.

Blood electrolysis levels in long-term occupational exposure to carbon disulphide
The effects of ≤25 years exposure to low air concentrations of carbon disulfide (CS2) were examined in a group of 95 workers in a viscose rayon plant. Workers exposed for ≤5 years had increases in plasma sodium and chlorine levels and decreases in erythrocyte potassium and calcium levels as well as decreases in the calcium transmembrane gradient, the calcium/magnesium ratio in both blood compartments and in the calcium/phosphorus ratio in erythrocytes. Exposure for >10 years caused a slight increase in plasma potassium and a decrease in plasma calcium and in the sodium transmembrane gradient and an increase in the potassium/calcium plasma ratio. Workers with 6-10 years exposure showed effects falling between these two. Because of excessive individual variability in blood electrolyte values they cannot be recommended as laboratory signs of chronic CS2 effects.

Exposure to sulfur compounds in pulp mills
Rikkiyhdisteet selluloosatehtaiden työilmassa [in Finnish]
Sulfur compound concentrations were measured in the air of 4 pulp mills using the sulfite digestion process, and in 6 using the sulfite process. The compounds measured were hydrogen sulfide, methyl mercaptan, dimethyl sulfide and dimethyl disulfide. In sulfite mills the concentration of sulfur dioxide was also measured. Between 100 and 160 air samples were taken in each mill. Analysis was by a gas chromatograph equipped with a flame photometer. The highest concentrations of sulfur compounds were those of sulfur dioxide in sulfite process mills, and those of methyl mercaptan and dimethyl sulfide in sulfite process mills. They often exceeded the TLVs. Sulfur compound concentration by location in the mills is analysed. Maintenance, cleaning and laboratory workers are most exposed to sulfur compounds, since production workers work in well-ventilated control rooms.

Volumetric method for the determination of carbon disulphide in air using personal sampling and adsorption by active charcoal
The CS2 is desorbed from the charcoal directly in the sampling tube by discontinuous chromatographic elution with 8ml water-alcohol solution of potassium hydroxide. A concentrated acetate buffer and a mixture of sodium azide and iodine are added to the eluate. The amount of free iodine reacting with azide is proportional to the CS2 concentration in the reaction mixture. Unreacted free iodine was retitrated with arsenite solution. The CS2 content is estimated from calibration curves. Mercaptans, hydrogen sulfide, xanthogenates and sulfides had no effect on the determination. Advantages of the method are minimal need for instrumentation, and stability of stock reagents.

Cutaneous absorption of trivalent chromium: tissue levels and treatment by exchange transfusion
Description of a case in which a man was accidently immersed in hot acidic trivalent chromium sulfate solution but none was swallowed. The clinical course was dominated by burns, intravascular haemolysis and acute renal failure. Blood concentrations of chromium were measured during treatment, and tissue concentrations were measured at death. Exchange transfusion reduced blood chromium concentration by two-thirds. The total quantities of chromium absorbed and removed by various routes were calculated. In-vitro studies showed that the chromium solution did not directly cause haemolysis.

Tear production was measured in the eyes of 6 subjects exposed to sulfur dioxide at 50ppm for 5min when the eyes was unshielded and when it was shielded with a contact lens. In the unshielded eye tear production increased an average of 83%. In the shielded eye no increase in tear production occurred. No subjects reported any subjective sensation of eye irritation with exposure of the shielded or unshielded eye. The absence of tear production in the shielded eye resulted from physical shielding of the chemically sensitive areas of the cornea and was not the result of the lens interfering with the mechanism of tear production.

Acute toxic exposure to gases from liquid manure
Report on 6 cases of poisoning following acute exposure to gases from liquid manure in industrial livestock production facilities. In the storage of liquid manure, the activity of anaerobic and facultative microbes results in the production of various gases as metabolic by-products, including CH4, NH3, CO2 and H2S. In the cases in question, H2S appears to have been the main toxic substance involved, and agitation of the liquid manure was important in creating an acute, highly toxic environment. Preventive measures include worker education about the danger of gaseous emanation from liquid manure and limitation of exposure (covers or lids on manure pits, adequate ventilation, etc.).

A morbidity study of viscose rayon workers exposed to carbon disulphide
Report on a comparative historical cohort study of morbidity in workers exposed to CS2 in a viscose rayon factory and in controls in a cotton mill in Japan between 1966 and 1970, using records of medical tratment. Period prevalence rates of cerebral vascular disease, ischaemic heart disease, hypertensive disease, diabetes mellitus, nephritis and nephrosis, mental disorders and neurological diseases were calculated. Renal disease and hypertension disease were significantly more prevalent in the rayon spinners and cutters with exposure histories of 10 years or more (i.e. the most highly exposed group) than in the workers with no exposure to CS2. When the group of workers with no CS2 was combined with that having negligible exposure and taken as a reference group, ischaemic heart disease was significantly more prevalent in the most highly exposed group than in the reference group. Ratios of period prevalence rates between these groups were 7.6 for nephritis and nephrosis, 2.3 for ischaemic heart disease, and 1.9 for hypertensive disease.

Early evaluation of potential worker exposure problems associated with the Claus-type sulfur recovery process
The design plans for a Claus-type sulfur recovery unit were reviewed for potential worker exposures to sulfur gases (hydrogen sulfide, sulfur dioxide), ammonia, dusts and noise. Controls for these potential exposures include double mechanical seals for centrifugal pumps carrying sour water, flushing and drain connections for each piece of equipment, closed loop systems for sample collection and other engineering design items. Engineering controls implemented at plant design stage minimise the risks of worker exposure and reduce the cost for retrofit engineering controls.

Cerebral damage following a single high exposure to carbon disulphide
A healthy 48-year old man was exposed for 20min to carbon disulfide (CS2) in the concentration range 400-470,000ppm as a result of a laboratory fire. He was unconscious for 10min after the exposure. Serious persistent cerebral deterioration developed. Computerised tomography scanning showed cerebral atrophy, neuro-psychological examination established dementia, and measurement of cerebral flow showed reduced cortical flow in the right hemisphere. Symptoms were still present 21 months after the exposure. The observed encephalopathy may be due to the direct toxic effects of CS2, or its metabolites, on the brain or to sequelae after anoxia during unconsciousness.
