Validation of a simpler method for determination of atmospheric sulfur dioxide
The determination of atmospheric sulfur dioxide as aqueous bisulfite using 5,5'-dithiobis(2-nitrobenzoic acid) (DTBN) was validated as a simple, rapid and reliable procedure. Standard sulfur dioxide concentrations in air (0-2.6ppm) were generated by means of a permeation device. Sulfur dioxide from air samples was absorbed in pH7 phosphate buffer and determined as bisulfite. The mean percentage recovery of sulfur dioxide is 101.4; the slope of the validation line determined by linear regression analysis is 1.014 found/calculated (1.4% absolute error; 0.9976 correlation coefficient).

A new look at physiologic respiratory response to H2S poisoning
Ever since the role of the carotid bodies in controlling ventilation was elucidated by Heymans in 1932, researchers have puzzled over the seeming paradox presented by the action of hydrogen sulfide gas on the nervous system. The dominant effect is depression of function, but the neural receptors of the carotids appear to be stimulated, resulting in hyperpnoea at sublethal exposures. This effect is examined in the light of the known cellular mechanisms of poisoning by H2S, which inhibits the enzyme cytochrome oxidase, stopping oxidative metabolism. The argument is made that H2S affects the carotid sensors in the same manner as reduced oxygen tension, thus resulting in increased rate and depth of ventilation.

Laboratory validation of a passive length-of-stain dosimeter for hydrogen sulfide
The dosimeter consists of a sealed glass tube containing a length of impregnated paper. To use the dosimeter, one end is broken off and the tube is inserted in a transparent plastic holder which can be attached by a clip to the wearer's clothing, near the breathing zone. The dosimeter covers the concentration range from about 0.5 to 150ppm. Accuracy of the device is well within the NIOSH guideline of ±25%.

Occupational hygiene in the production of chlorine-free potash fertilisers
Gigiena truda v proizvodstve beshlornyh kalijnyh udobrenij [in Russian]
The principal occupational hazards in chlorine-free potash production are potassium sulfate and potassium magnesium sulfate dusts, which are present in workplace air at concentrations from a few to hundreds of milligrams per cubic meter. The dust affects the respiratory systems of workers and lowers their resistance to other negative factors. Animal experiments showed that the compounds are somewhat toxic and mildly irritating to the skin and mucous membranes. The biochemical, physiological and morphological effects of the compounds suggest that the threshold of chronic effects of chlorine-free potash is around 15mg/m3.

Ammonium persulphate sensitivity in hairdressers
Ammonium persulfate is a component of hairdressing bleaches. 12 of 49 professional hairdressers patch tested with ammonium persulfate gave positive reactions, in contrast to 1 of 118 patients who were not hairdressers. 7 out of 10 of these 12 patients have since given up hairdressing. The stability of ammonium persulfate preparations in petrolatum or water was tested; about 24% of the initial amount of the compound degraded in 6 months. This suggests that preparations this old or older should not be used.

Poisoning due to carbon disulfide - a powerful disinfectant
Un désinfectant radical ou une intoxication par le sulfure de carbone [in French]
Case study of carbon disulfide poisoning due to the use of a disinfectant in the cleaning of incubators. The subject was suffering from chronic carbon disulfide poisoning followed by treatment and, after a 1-year interruption of exposure, by an episode of acute poisoning brought on by renewed exposure. Chronic poisoning can result in psychological disturbances, anorexia, weight loss, diarrhea, and ultimately in sensomotor polyneuritis and in retrobulbar optic neuritis. The symptoms of acute poisoning are psychological, neurological and digestive problems. The disease is recognised as an occupational disease in France. This product (Lomasept) is still used in the silk industry and in agriculture as an insecticide.

Health implication of occupational exposures to hydrogen sulfide
Retrospective study of 250 Canadian workers who submitted compensation claims in Alberta between 1979-1983, following exposure to hydrogen sulfide (H2S). 54% of these workers became unconscious after exposure. Symptoms with a neurological component accounted for the largest group of clinical findings. Other major symptoms were respiratory and ophthalmologic disorders. The overall fatality rate was 2.8%, significantly lower than that reported (6%) a decade earlier. This is attributed to improved first-aid and increased awareness of the dangers of H2S. Traumatic injury as a result of a fall after exposure was noted in 31 cases.

Filter method for active and passive sampling of sulfur dioxide in air
En metod för aktiv och passiv provtagning av svaveldioxid i luft med impregnerade filter [in Swedish]
Sulfur dioxide is collected on filters impregnated with glycerol/potassium hydroxide solution. Sampling can be carried out with a pump or by using either of 2 different passive monitors available on the market. Analysis is performed by ion chromatography. These methods were evaluated and compared to a colorimetric air monitoring badge system (ProTek). Laboratory tests showed that the accuracy of the filter methods is good and that samples can be stored. Water vapour does not interfere, but hydrogen sulfide does cause a minor decrease in recovery. ProTek displays high accuracy, but storage tends to decrease recovery. Field tests in a steel rolling mill and a sulfite pulp mill showed fairly good correspondence between the methods.

State of the upper respiratory tract in industrial workers exposed to vapours of nickel sulfate
Sostojanie verhnih dyhatel'nyh putej u rabočih promyšlennyh predprijatij pri vozdejstvii parov sernokislogo nikelja [in Russian]
Study of 38 workers engaged in electrochemical nickel plating. Although nickel sulfate vapour in the air of the shop was well below the maximum allowable concentration, 25 of the workers had complaints of nasal discharge, sneezing, dryness and obstructions in the throat. Tissue abnormalities were found in the noses and larynxes of 34 workers, with allergic reactions being most common. All types of pathology observed, except chronic tonsillitis, were more frequent than in a control group. Whereas the frequency of chronic rhinitis was about the same at all age and seniority levels, allergic changes in the upper respiratory mucosae increased in frequency with length of service.

Electrical conductometric gas analyser
Ėlektrokonduktometričeskij gazoanalizator [in Russian]
A new gas analyser for continuous automatic monitoring of water-soluble toxic contaminants (ammonia, hydrogen sulfide, etc.) in the range of their maximum allowable concentrations was devised. The apparatus consists of 3 parts: electrochemical and electrometric units and an aspiration device. Gas concentrations are measured by comparison of the electrical resistance of absorption liquid in conductometric cells before and after absorption of the gas. The absorption liquid is 0.01% hydrochloric acid. Concentrations of ammonia from 0 to 100mg/m3 can be measured with 0.5% precision and at the sensivity limit of 0.1%. Determination of ammonia requires that 0.1-0.15L/min of air be passed through the electrometric chamber of the apparatus. A diagram of the apparatus is given.

A filter method for the active and passive monitoring of sulfur dioxide in workplace air
Sulfur dioxide is collected on impregnated filters and passive dosimeters (Abcor Gasbadge and 3M) using a glycerol/potassium hydroxide solution as collection medium. Analysis is made by ion chromatography. The methods were evaluated by comparison against the Pro-Tek (Du Pont) colorimetric badge system. All three methods gave acceptable results. Water vapour did not interfere but H2S caused a minor decrease in recovery. A collection efficiency of >98% was achieved for all the samples. For the Pro-Tek dosimeters, recovery after 4 weeks storage (refrigerated) was only 84%. This confirms the 3-week storage limit recommended by the manufacturer.

Spirometric tests and electrocardiograms were performed on 200 present and past employees of a sulfur mine (length of employment: 5-30 years). Significant reductions in vital capacity (average 30%), in FEV1 (25-30%), increases in relative residual volume (29% in miners 39-45 years old, 57% in miners over 66 years old) and in residual volume/total lung capacity relation (by 36-43%, depending on age) were found. Significant changes in heart function occurred in 20% of the subjects (disturbances of atrial-ventricular conduction and of conduction in blood vessels on the right side of the body). Hypotheses for the aetiology of these changes are given.

Historical and present-day trends in biological monitoring of industrial exposure to carbon disulfide
Historiek en hedendaagse trends in de biologische monitoring bij industriële expositie aan koolstofdisulfide [in Dutch]
So far the iodine-azide urine monitoring test is the only carbon disulfide (CS2) exposure test recognized by the World Health Organization. However, one of the drawbacks of this test is that it cannot be used for low exposure levels corresponding to the TLV proposed by NIOSH for CS2. The discovery of the urinary CS2 metabolite 2-thiothiazolidine-4-carboxylic acid (TTCA) opens new prospects for the evaluation of CS2 exposure, because this metabolite can be detected in the urine of workers exposed to very low atmospheric concentrations of CS2.

Cancer mortality among carbon disulfide-exposed workers
In a 15-year prospective follow-up of 2 industrial cohorts consisting of 343 viscose rayon plant workers exposed to carbon disulfide (CS2) and a similar number of paper mill workers, mortality from lung cancer was lower in the viscose rayon workers. The mortality rate ratio of 0.46 was not statistically significant. Deaths from other neoplasms numbered 10 in both cohorts. When the Finnish national death rates for 1975 were taken as a standard, the rayon plant workers still showed a favourable mortality experience for lung cancer, but neither of the relative rates differed statistically significantly from the general standard. Competing causes of death, mainly cardiovascular diseases, were statistically accounted for by life-table techniques. 55% of the rayon plant workers were smokers compared to 49% of the paper mill workers. Under moderate conditions of exposure it appears that CS2 is not carcinogenic.

Nordic Expert Group for Documentation of Exposure Limits - 48. Sulfur dioxide
Nordiska expertgruppen för gränsvärdesdokumentation - 48. Svaveldioxid [in Swedish]
Criteria document for establishment of an exposure limit for sulfur dioxide. Exposure to low concentrations (>3mg SO2/m3) produces bronchoconstriction and elevated airway resistance; bronchoconstriction disappears quickly after cessation of exposure. Exposure to higher concentrations irritates the nose and throat; the irritation becomes intolerable at concentrations of 130-160mg/m3. Such concentrations produce serious lesions in the bronchial mucosa. High concentrations, such as those resulting from accidents, produce pulmonary oedema and toxic pneumonia. Exposure of monkeys and dogs to 3-13mg/m3 for 2 years gave no detectable lesions in their respiratory organs. The available data suggest that a concentration of 13mg/m3 will not accelerate the decline in spirometric parameters that occurs with age. In an annex: SO2 exposure limits in 21 countries; method of sampling and analysis.

Relation between the iodine azide test and the TTCA test for exposure to carbon disulphide
Description of a method of carbon disulfide exposure evaluation that uses quantification of 2-thiothiazolidine-4-carboxylic acid (TTCA) in urine. This method is to be preferred to the method using the iodine azide test, which can give false positive results and whose readings have a strong subjective component. TTCA concentration increases in urine during workshift hours in a viscose plant were found to correlate well with carbon disulfide exposure levels. This correlation was especially good if urine samples with creatinine concentrations below 1mg/mL and above 3mg/mL were disregarded.

Chest pain in rubber chemical workers exposed to carbon disulphide and methaemoglobin formers
This study of chest pain and/or coronary heart disease (CHD) was carried out on 94 rubber-chemical workers exposed to carbon disulfide (CS2) and methaemoglobin-forming aromatic amines, and on 87 controls. Matching the workers and controls for known CHD risk factors, the association between the chemicals and diseases studied could be measured. Chest pain and angina pectoris were significantly related to exposure. Abnormal ECGs were more numerous in the exposed group, but the difference was not significant. An acute effect of exposure on the heart cannot be demonstrated.

Sulfur dioxide and ammonium sulfate effects on pulmonary function and bronchial reactivity in human subjects
The effect of exposures to 1ppm sulfur dioxide and 500µg/m3 respirable ammonium sulfate particles was studied in 20 non-smoking subjects while performing 15min exercises during 4h exposure periods in an environmental chamber. Response to exposure was measured by pulmonary function tests and bronchial reactivity to methacholine. No significant changes were observed after separate or combined exposures to the 2 contaminants.

Laboratory validation and field verification of a new passive colorimetric air monitoring badge for sampling hydrogen sulfide in air
This dosimeter has been validated over the range of 1.8 to 164ppm-h (0.23-21 ppm H2S for 8h). Analysis is based on the Texas Air Control Board's molybdenum blue colorimetric method; colour-activated exposed badge solutions are read out on a spectrophotometer set at 580nm and using 10mm cells. The overall accuracy is ±16%; variations in temperature (10-40°C), relative humidity and face velocity (0.6-76m/s) do not affect badge performance. Unexposed badges are stable for 12 months refrigerated or 2 months at room temperature. Exposed badges can be stored for 1 week at room temperature or 1 month refrigerated. There are no significant interferences from other contaminants.
