Air monitoring and assessment of occupational exposure to peracetic acid in a hospital environment
A new automated method based upon solid phase micro-extraction (SPME)/fast gas chromatography-mass spectrometry (GC-MS) was used in the regional hospital of Florence for the quantitative determination of airborne peracetic acid (PAA). The method is suitable for the quick assessment of brief acute exposure as well as for long-term environmental monitoring of PAA and can assist in improving safety and environmental quality in workplaces where disinfectants are used. During a monitoring campaign in Italy, the 8h average air concentration of PAA was 1/10 of the threshold limit value of time weighted average in 87% of the clinical units tested. However, the application of the new SPME method showed that short-term exposure to PAA could be relatively elevated in some hospital units with poor ventilation, allowing prompt intervention in order to reduce worker exposure to this potentially toxic compound.

Organic acids and bases: review of toxicological studies
Organic acids and bases are among the most frequently used chemicals in the manufacturing industries. However, only a few have had a full toxicological evaluation and even fewer have had occupational exposure limits established. The paper reviews the acute and chronic toxicity data of organic acids and bases, and considers the mechanism by which these chemicals produce their effects. A methodology for establishing preliminary occupational exposure limits based on the physicochemical properties of these chemicals is presented. Workplace exposure limits for 20 organic acids and bases which currently have no exposure guidelines are suggested. Advice regarding appropriate medical treatment of exposure to these substances is discussed.

Massagers and skin diseases
Masseurberuf und Hautgefährdung [in German]
The number of dermatoses among masseurs has increased rapidly in recent years. Patch tests have revealed allergies towards natural plant substances, such as cinnamaldehyde, used in massage lotions. Nine allergens were identified which are listed in a table. They are all substances occurring naturally in plants and trees.

Hygienic significance of air pollution with tobacco dust
Gigieničeskoe značenie zagrjaznenija vozdušnoj sredy tabačnoj pyl'ju [in Russian]
This literature survey presents in concise form data on tobacco production at home and abroad, chemical composition of tobacco and health effects of tobacco dust on experimental animals and tobacco industry workers. Nicotine, pesticide residues and flavourants seem to be the main health hazards in the industry. Experimental data on animals are consistent with field observations on humans. Female tobacco workers often suffer late toxaemia of pregnancy, abnormal pregnancy interruptions and weakness in labour. Infants born to exposed mothers more frequently show signs of asphyxia and congenital anomalies at birth than those of control women. Tobacco workers suffer allergic disorders in the form of allergic rhinitis, sinusitis, tonsillitis, bronchitis, hepatitis and asthma. Occupational exposure to tobacco dust also affects the cardiovascular system (strong palpitation, heartache, dyspnoea). Arterial hypertension, hypotension, S-A bradycardia, tachycardia and arrhythmia have also been observed. The data call for further probing of the biological effects of tobacco dust, hygienic evaluations of tobacco manufacturing undertakings' environmental conditions and working out of measures for controlling atmospheric pollution by these undertakings.

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.

Interactions of m-xylene and aspirin metabolism in man
The interaction between m-xylene and aspirin was studied on five male volunteers who were exposed to m-xylene by inhalation (100ppm), aspirin (1,500mg) by mouth, and m-xylene and aspirin together under controlled conditions in an exposure chamber. Urine and blood samples were collected and analysed for m-xylene, aspirin, and their metabolites. The amounts of the major glycine conjugates produced from m-xylene (m-methylhippuric acid) and aspirin (salicyluric acid) were significantly reduced by about 50% when m-xylene and aspirin were coadministered. There appears to be a mutual inhibition on the formation of the respective glycine conjugates due to competition for either the enzymes, acyl-CoA synthetase, or glycine N-acylase. These findings have implications in the biological monitoring of workers exposed to m-xylene.

Occupational dental disease due to acids
Berufsbedingte Säureschäden der Zähne [in German]
Statistical analysis, by industrial sector, sex and length of exposure of 1,016 cases notified between 1971 and 1973 in the Fed.Rep. of Germany. 90% of the dental decay was due to organic acids (bakers' caries), most of the cases being found among workers in bakeries, pastry and confectionery establishments, and flour mills. The other 10% of dental decay cases was due to inorganic acids used in various industries. The article examines the aetiology of dental decay due to organic acids, dietary habits being considered the prime cause of caries. Description of the causes and signs of dental damage due to inorganic acids. Because microbial action is involved in bakers' caries, whereas dental disease due to mineral acid is caused by a decalcification process, the signs and location of dental decay are different in the 2 cases.
