Введение. Загрязнение атмосферного воздуха по данным Всемирной Организации Здравоохранения наносит огромный ущерб здоровью населения по всему миру. Твердые взвешенные частицы атмосферного воздуха представляют собой гетерогенную смесь веществ с различными размерными, качественными и количественными характеристиками и являются ключевым индикатором загрязнения воздуха, способствуя формированию бронхолегочной патологии. На данный момент не существует единого рекомендованного ранжирования содержания твердых взвешенных частиц в атмосферном воздухе.

Цель

Цель. Определение фракционного содержания твердых взвешенных частиц в приземном слое воздуха районов г. Владивостока с высокой и относительно невысокой техногенной нагрузкой.

Материалы и методы

Материалы и методы. Пробы атмосферного воздуха отбирались «в зоне дыхания» при помощи электрического аспиратора. При гранулометрическом анализе твердых взвешенных частиц устанавливалось распределение частиц по размерам, выраженное в процентах, и массовая концентрация фракций (мкг/м3). Выделены диапазоны размерности частиц с учетом возможного происхождения и предполагаемых патофизиологических особенностей их воздействия на организм.

Результаты

Результаты. Для территории с высокой техногенной нагрузкой г. Владивостока характерно превалирование наиболее патогенных для организма частиц диаметром до 10 мкм. В районе с относительно невысокой техногенной нагрузкой преобладают частицы более крупных фракций (10- 25, 1000-2000 мкм).

Заключение

Заключение. Изучение параметров твердых взвешенных частиц конкретных территорий и установление клеточных механизмов их влияния на организм могут помочь в разработке новых стратегий профилактики экологозависимых патологий.

Introduction

Introduction. According to the World Health Organization ambient air pollution causes enormous harm to public health around the world. Atmospheric solid suspended particles are a heterogeneous mixture of substances with various dimensional, qualitative and quantitative parameters. They are a key indicator of air pollution, contributing to the bronchopulmonary pathology formation. At the moment, there is no general recommended ranking of the solid suspended particles amount in the atmospheric air.

Aim

Aim. Determination of the SSP fractional content in the air ground layer in high and relatively low technogenic load areas of Vladivostok.

Materials and methods

Materials and methods. Atmospheric air samples were taken «in the breathing zone» using an electric aspirator. In the granulometric analysis of SSP, the particle size distribution, expressed as a percentage, and the mass concentration of fractions (μg/m3 ) were determined. The ranges of dimensions have been identified, taking into account the solid suspended particles possible origin and the expected pathophysiological features of their effect on the organism.

Results

Results. An area with a high technogenic load is characterized by the prevalence of particles with a diameter of up to 10 microns, which have the most pathogenic effect on the organism. In an area with a relatively low technogenic load, particles of larger fractions (10-25, 1000-2000 microns) predominate.

Conclusion

Conclusion. Studying the solid suspended particles parameters in specific areas and establishing their influence cellular mechanisms can help in the development of new strategies for the prevention of environmentally-related pathologies.
