Hematological parameters in workers of water supply facilities of petrochemical enterprises

Introduction. One of the major petrochemical complexes of the Republic of Bashkortostan is Limited liability company (LLC) «Gazprom Neftekhim Salavat». The normal operation of industrial enterprises requires the use of large volumes of water. Its water supply, water disposal, waste disposal, reclamation of sludge reservoirs, equipment repair, cleaning of oil sludge reservoirs is provided by LLC «PromVodoKanal». The main technological personnel are wastewater treatment operators, process plant operators, pumping plant operators, chemical analysis laboratory assistants, commodity operators. Their work is associated with exposure to harmful and / or dangerous production factors.

Objective. Search and substantiation of laboratory markers of early health disorders in workers of water supply facilities of petrochemical enterprises.

Materials and methods. Hygienic and clinical laboratory studies were carried out among workers of the main occupations of the «PromVodoKanal» station who have contact with various harmful derivative factors. A complex of hematological and biochemical research methods was used in the work.

Results. A comparative analysis of the frequency of occurrence of deviations of hematological parameters from the norm in all examined (occupational) groups was carried out. A laboratory study showed that hematological parameters are characterized by an increased content of hemoglobin, erythrocytes, and hematocrit. Changes in the mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC), and thrombocytes count, were detected in every fifth worker. Over the years of work, the share of workers with high levels of glucose and cholesterol increases markedly, the correlation of which reaches from 0.90 to 0.97.

Limitations. The article has limitations on the scientific study of working conditions, as periodic medical examinations are carried out by occupational pathologists.

Conclusions. Red blood values are specific markers of workers’ health problems and require special attention during periodic medical examinations.

Compliance with ethical standards. The research was conducted in accordance with the ethical standards of the Declaration of Helsinki 2000. Minutes of the meeting of the BEC dated March 10, 2022, No. 01-03.
