Industrial chemical paint strippers
Les décapants chimiques industriels [in French]
Paint strippers consist of concentrated formulations of varying complexity containing one or the other of the following substances: dichloromethane (50% of paint strippers); sodium or potassium hydroxide (25% of paint strippers are alkaline with a pH>13); phosphoric, hydrochloric, hydrofluoric, nitric or sulfuric acid (90% of pickling liquors and 70% of strippers for ovens). Being mostly caustic and corrosive, these substances can give rise to possibly severe irritation of the skin, and the respiratory and ocular mucous membranes. There is also a risk of inflammation from hydrocarbons and oxygenated compounds, together with the harmful and suspected carcinogenic effects of dichloromethane (classified R40).

Mortality and cancer incidence in chloralkali workers exposed to inorganic mercury
Mortality and cancer incidence were studied in men exposed to inorganic mercury at eight Swedish chloralkali plants where individual biological monitoring data were available. Urinary mercury excretion has declined from about 200µg/L during the 1950s to less than 50µg/L today. These workers had also been exposed to chlorine and static magnetic fields. At some of the plants there had been a low degree of exposure to asbestos. In total, 1190 men had been monitored for at least one year between 1946 and 1984. Their mortality and cancer incidence were compared with those of the general male population. Mortality from all causes was not significantly increased. Cardiovascular mortality was slightly increased for no known reason. An excess of lung tumours was seen possibly caused by previous exposure to asbestos. Mortality from non-malignant diseases of the brain and the kidneys, the main target organs in mercury poisoning, was not increased, nor was the incidence of brain tumours (3 observed v 1.1 expected) or kidney tumours (3 observed v 1.9 expected).

EEG findings in chlor-alkali workers subjected to low long term exposure to mercury vapour
The cerebral effect of long term (mean 15.6, SD 8.9 years) and low (about 25µg/m3 air) exposure to mercury vapour was studied in a group of 41 workers in a chlor-alkali plant and in a group of matched controls by electroencephalography (EEG). In the visually interpreted EEGs only a tendency for an increased number of EEG abnormalities, especially focal ones, could be seen in the exposed subjects. In the computerised EEG (cEEG), however, the exposed workers had significantly slower and more attenuated EEGs than the controls. This difference was most prominent in the occipital region, became milder parietally, and was almost absent frontally. Our results suggest that cEEG may show early effects on the brain of exposure to mercury vapour.

Subjective symptoms and psychological performance of chlorine-alkali workers
Subjective symptoms and psychological performances on a computer-administered test battery were studied among a group of 60 chlorine-alkali workers and their matched referents. The exposure time of the group exposed to inorganic mercury vapour had been about 14 years, and the estimated long-term average exposure had been about 25µg/m3 of air. The exposed workers had an actual mercury concentration of 51.9 (SD 25.0, range 15-150) nmol/L in blood and 84.1 (SD 56.6, range 15-260) nmol/L in urine. Neither perceptual motor nor memory or learning abilities of the mercury-exposed workers showed any disturbances in a comparison with the referents. However, the exposed group reported statistically significantly more memory disturbances than the referents. Strain caused by three-shift work was a possible cofactor for other increased subjective symptoms, namely, for sleep disorders, fatigue, and confusion.

Setting occupational exposure limits for irritant organic acids and bases based on their equilibrium dissociation constants
The most common adverse effect of exposure to chemicals in the workplace is irritation. Although there is a great diversity among irritants, a large number of them are organic acids and bases. This study showed that there is an association between the equilibrium proton dissociation constant and the occupational exposure limits (OELs) of organic acids and bases that produce irritation as the primary adverse effect. On the basis of this relationship, preliminary occupational exposure limits for other similar compounds with no existing Threshold Limit Values or workplace Environmental Exposure Limits can be estimated.

Eye irritation testing
This report discusses the Draize rabbit eye test and alternatives. The test may overestimate the ocular hazard to man in some cases, but appears to be effective in demonstrating the absence of ocular hazards. More data on human eye irritation must be collected if the correlation is to be improved. Alternative tests are insufficiently validated to replace the rabbit model, but some may be useful for initial screening. The various present systems for classifying ocular hazards are so different that a given chemical can be classified in several different ways on the basis of the same experimental data. Recommendations: modification of the test to minimise the number of animals used and the discomfort to which they are subjected; harmonisation of classification systems.

Nordic Expert Group on the Documentation of Threshold Limit Values - 56. Hydrazine and hydrazine salts
Hydrazin og hydrazinsalte [in Danish]
Nordiska expertgruppen för gränsvärdesdokumentation - 56. Hydrazin och hydrazinsalter [in Swedish]
Hydrazine and its salts are readily absorbed into the body through the skin, the lungs and the gastro-intestinal tract. Absorbed hydrazine is distributed to most organs, but the highest concentrations are found in the kidneys. Hydrazine is metabolically degraded by mixed-function oxidases, mainly to nitrogen and water. Other important metabolites are N-acetylhydrazine and 1,2-diacetylhydrazine. Hydrazine and its metabolites are mainly excreted via the urine or via exhalation. The oral LD50 of hydrazine in rodents is about 60mg/kg body weight. The toxicological mechanism is probably inhibition of enzymes in the gamma-aminobutyrate system. Pure hydrazine is highly corrosive, and dilute solutions of hydrazine and salts are irritating to the skin and to the mucous membranes. Hydrazine and its salts are also potent sensitisers. In long-term exposure experiments, the liver is the most sensitive organ: fatty liver has been produced in mice (but not in rats). In rodent studies, hydrazine is carcinogenic, teratogenic and embryotoxic, and its effects the morphology of sperm. Hydrazine and its salts damage DNA and produce mutations in bacterial and mammalian cell cultures. Occupational exposure limits should be based on the carcinogenic and reproductive effects of hydrazine and its salts.

A new material: Bristar
"Bristar" - ein neuer Arbeitsstoff [in German]
Presentation of a new material which increases greatly in volume when dissolved in water. This substance can be substituted for explosives in certain cases. Inserted into rick, or into a concrete wall, for instance, it cracks open and disintigrates the rock or concrete after about 10 hours. It is non-toxic, noiseless, and does not cause vibration or flying particles. Its use, however, involves the hazard of caustic burns, due to its principal constituent: caustic lime. This necessitates the wearing of protective goggles and clothing. An off-limits hazard area should be fenced or marked off around the object to be disintegrated, until the operation is completed and checked. Final demolition work on buildings treated in this manner requires special safety precautions.

Reports on 4 men who sustained severe burns on the legs after contact with premixed concrete. In 2 cases contact occurred when the concrete spilled over the top of their boots as they were using their feet and lower legs to spread it in a trench. As such "treading" is a common method of spreading cement in the construction industry, and such injuries are rare, the liquid in the wet cement must have had an unusually high alkalinity.
