“…Однако существует целый ряд публикаций, свидетельствующих о связи воздействия искусственных минеральных волокон с мезотелиомой плевры и раком легкого [8][9][10][11][12][13][14], а также обнаруживающих наличие цитотоксического и генотоксического эффектов воздействия каменной ваты [15,16]. С воздействием искусственных минеральных волокон также связывают высокий риск развития пневмокониоза [17], патологии сердечно-сосудистой системы [3], гиперкератозов с высокой вероятностью малигнизации [18].…”

Объектом настоящего исследования явилось состояние здоровья работников, имеющих контакт с аэрозолями искусственных минеральных волокон. Цель исследования-определение особенностей динамики и структуры заболеваемости с временной утратой трудоспособности (заболеваемость с ВУТ) и оценка профессионального риска здоровью работников, имеющих контакт с аэрозолями искусственных минеральных волокон. Представлены результаты углубленного интерпретационного анализа заболеваемости с ВУТ круглогодовых работников производства теплоизоляционных плит из минеральной ваты (основная группа) за пятилетний период с учетом пола, возраста и стажа работы. Оценка производственной обусловленности заболеваемости проведена при сравнительном анализе с группой условного контроля (цех производства блоков из ячеистого бетона), республиканскими показателями и показателями отрасли производства строительных материалов. Оценка риска проведена с использованием индекса профессионального риска, рассчитанного на основе показателя относительного риска и суммарного коэффициента условий труда. Установлено, что уровни заболеваемости с ВУТ работников основной группы достоверно выше таковых группы сравнения как в целом по всем классам болезней, так и по классу болезней органов дыхания в частности. Относительный риск и этиологическая доля заболеваемости, обусловленной условиями труда, свидетельствует о непосредственном их влиянии на заболеваемость болезнями органов дыхания в основной группе. Индекс профессионального риска характеризует профессиональный риск в основной группе как умеренный, требующий специальных мер по его снижению, но без необходимости их немедленного проведения. В основной группе также установлен более низкий «индекс здоровья» по сравнению с группой условного контроля. Уровни заболеваемости с ВУТ работников основной группы достоверно ниже среднемноголетних уровней в целом по Республике Беларусь, а также нормирующих показателей в отрасли производства строительных материалов, но статистически значимо выше республиканских и отраслевых по классам болезней органов дыхания и болезней костно-мышечной системы и соединительной ткани, а также статистически значимо выше республиканских по классам болезней органов пищеварения и болезней кожи и подкожной клетчатки. Ключевые слова: производство минеральной ваты, искусственные минеральные волокна, промышленные аэрозоли, условия труда, заболеваемость, профессиональный риск, профессионально обусловленные заболевания, динамика заболеваемости.

Early diagnostic and prognostic criteria for health disorders in chemical workers

et al. 2020

View full text Add to dashboard Cite

The production of synthetic materials - fiberglass and rubber-technical products, as well as products derived from oil refining wastes continues to grow. A characteristic feature of the working conditions of these enterprises is the content of chemicals of hazard class 1-4, which may be potentially hazardous to workers. It imperative to justify prenosological laboratory criteria for health problems of manufacturing workers. The results of the hematological, biochemical, immunological and cytochemical parameters among manufacturing workers are presented. Significant changes in the processes of oxidative metabolism, lipid metabolism, impaired immune status, and intracellular enzyme activity were found in a significant proportion of the workers. Changes were detected in workers even with a short work experience (5 years) and of young age (20-30 years). With an increase in the occupational length of service, the frequency of these disorders increased. Based on the results obtained, early diagnostic and prognostic criteria for health disorders in workers of diverse chemical industries are substantiated. Based on the results obtained, early diagnostic and prognostic criteria for health disorders in workers of diverse chemical industries are substantiated. For rubber manufacturing workers: increased malonic dialdehyde, reduced catalase activity, the activity of catalase is lowering; increased enzymes activity (AST, ALT, GGT), protein abnormalities, erythropenia, decreased hemoglobin levels, increased reticulocyte. For fiber glass manufacturing workers: indicators of the oxidative antioxidant system, hemograms - increased lymphocytes, erythrocytosis, leukocytosis, increased CD3 +, increased CD4 +, CD 16+, CD 20 +, FAL, IgG, increased total protein, hyperfermentemia (GGT, ALT), changes in the intracellular enzymes activity - acid phosphatase of neutrophils and lymphocytes, decreased myeloperoxidase, increased glycogen levels. For olefin oxides manufacturing workers - this is hyperfermentemia (ALT, alkaline phosphatase), protein metabolism changes, increased red blood cells, reticulocytes, neutrophils, lymphocytes, eosinophils, platelets, leucopenia, decreased FAL, increased IgM, decreased IgA, IgG, changes in the intracellular enzymes activity - decrease myeloperoxidase, increase acid phosphatase of neutrophils and lymphocytes.

Introduction. Air pollution with aerosols of mineral fibers in the manufacturing heat-insulating building products is the primary harmful production factor that can increase the risks of developing several diseases of various organs and systems. It determines the relevance of conducting comprehensive studies of the dust factor in such industries, assessing the relationship between mass measurements and fibre counts, the development of targeted preventive measures, considering the features of the technological process. The study aims to conduct comprehensive hygienic studies of the dust factor in the manufacturing heat-insulating building products from basalt fiber and determine the morphological features of dust at different stages of the technological process, the presence of a relationship between mass measurements and fibre counts. Materials and methods. The studies were carried out based on manufacturing heat-insulating building products from basalt fiber. To assess the dust factor, the authors carried out the analysis of mass measurements of dust and fibre counts using phase-contrast light microscopy. The authors used linear regression analysis to study the dependence of the mass measurements and fibre counts. Results. The mass measurements of dust in the working area don't exceed hygienic standards and ranges from 0.51 mg/m3 to 1.19 mg/m3, and the fibre counts are from 0.45 f/cm3 to 1.23 f/cm3. The morphological analysis of the dust samples' preparations collected on filters from the air of the working area made it possible to reveal the characteristic features of the composition of the dust at various stages of the technological process. The study confirmed a positive correlation of weak strength between fibre counts and the mass measurements. The resulting dependence model is statistically significant, but the coefficient of determination of this model (R2) is 0.043. Fibre counts in the first phase of the production cycle are significantly higher than in the second. Simultaneously, the mass measurements do not have significant differences in different phases of the production cycle. Conclusions. There is a positive correlation of weak strength between fibre counts and mass measurements, but the resulting linear regression model can explain only 4.3% of the variation of fibre counts based on the mass measurements, which does not allow using this model for converting of the results of measurements of several particles. Microscopy of dust preparations makes it possible to determine the morphological picture characteristic of various stages of the technological process. Fibre counts depend on the phase of the production cycle. The data obtained can be used to design air purification systems and operating modes at various stages of the technological process.
