[The effect of occupational factors on immunologic indices in workers in the petroleum-refining industry].

Examinations of 518 refinery workers have helped define the dermatologic morbidity structure. Immunologic examinations have been carried out in 82 workers. 70 of these have developed skin abnormalities (toxicoderma, eczema, itching, hyperkeratosis, vascular spots, abnormal pigmentation, etc.). The studies have revealed reduced levels of the cell-mediated immunity parameters: T-lymphocytes, T-theophylline-sensitive lymphocytes, and decreased functional activities thereof); this has been parallelled by activation of the humoral immunity.

[The characteristics of photodermatoses in workers of the Apsheron petroleum industry].

Examinations of 518 refinery workers have revealed photodermatoses in 106. The disease ran a benign course: chronic or subacute one, eventuating in hyperpigmentation and vascular maculae in the workers exposed to oil and oil products. The patients suffering from occupational photodermatoses develop immunologic shifts, i.e. reduced levels of T-cells, T-suppressors, elevated counts of B-cells and of serum immunoglobulins G and M.

[Corneal sensitivity in workers in contact with petroleum products].

Evaluation of the corneal sensitivity was carried out in 251 workers who have had a direct contact with petrol and its derivates and in 45 persons of a control group. It was established that the corneal sensitivity--especially in its central region--was distinctly lowered in persons employed in the department of asphalt oxidation and cleaning of sewages. This concerned particularly the workers with a long-lasting, many years service.

[Changes in the liver function of workers exposed to petroleum products].

The function of the liver is examined in 120 workers (at 52 controls) in biological purification of the waters in a petrochemical plant, exposed to above the norm concentrations of strong hepatotropic chemical substances: benzene, toluene, styrene, aldehydes, ketones, mercaptans, acrylonitrile, octanole, butanol. etc. The established hyperenzymia, hyperlipaemia and significant reduction of glutathione in certain per cent of the workers (from 7 to 31% at different indices) points out an effect of the above mentioned toxic substances on the enzymic, lipidic and detoxic function of the liver. This proves the presence of certain potential risk for those working in this production and especially workers engaged in repair and technology process.

[Vanadium level in the urine of workers on a shift-work schedule during drilling of oil wells for high-vanadium petroleum].

The study was designed to analyze vanadium content in urine samples of 87 workers engaged in the production of high-vanadium oil and 50 persons of the control group. Statistical data verified an elevated vanadium content in the urine of oil miners and especially of operators of the shop of oil and gas production. Urine concentration of vanadium grew along with the increase in the length of service.

Health implications of petroleum distillate ingestion.

The authors discuss the clinical approach to the management of hydrocarbon ingestions, including the role, implementation, and type of gastric decontamination utilized; the extent of medical evaluation, observation or hospitalization required; and the appropriate therapy for hydrocarbon pneumonitis. An appendix covers myocardial sensitization following inhalation abuse of hydrocarbons.

[Biodegradation of petroleum hydrocarbons in soil inoculated with yeasts].

Yeast species belonging to the Candida genus were added to the greyish-brown soil of the Apsheron Peninsula under laboratory conditions. The rate of CO2 production was used to estimate the degradation of crude oil, paraffin, cycloparaffin and aromatic hydrocarbons as well as their oxidized products. The rate of hydrocarbon degradation in the soil inoculated with yeast cells was shown to drop down gradually. The effective action on the process of hydrocarbon degradation depended on the special properties of an inoculated population and on the structure of a hydrocarbon. Some yeast species stimulated the degradation of various aromatic hydrocarbons and their oxidized products. Aromatic hydrocarbons were decomposed at a lower rate comparing to their oxidized products. When the soil was inoculated with C. guilliermondii populations, n-hexadecane added to the soil at a concentration of 1% was decomposed within 250-300 days. Field experiments confirmed that crude oil biodegradation was more intensive in the soil inoculated with yeast cells.

Health-related research at the American Petroleum Institute.

On behalf of its oil-company members, API has studied the effects of the materials to which people may be exposed and aspects of the effects of the total work environment on employees' health. This chapter sets out the mechanisms by which the research is conducted, illustrates the type of research performed, and describes the availability of the results to those interested in the scientific community.
