Assessment of biological polluttion of soil in the Arkhangelsk Region

Self Cite

Our research goal was to comparatively analyze soils contamination with chemicals in cities located in the Arctic zone of Arkhangelsk region and to assess population health risk caused by soils in settlements contaminated with chemicals. The research has practical significance due to Arkhangelsk region being among the RF regions with the highest share of soils samples taken in settlements that deviate from hygienic standards as per sanitary-chemical and microbiological parameters. The assessment was based on monitoring data on chemical contamination of soils in cities located in the Arctic zone of Arkhangelsk region (Severodvinsk, Arkhangelsk, and Novodvinsk) collected in 2007-2017. We assessed population exposure to contaminants in soils at their oral and subcutaneous introduction and determined risk levels for children's and adults' health. To examine non-carcinogenic effects, we applied reference doses and calculated hazard coefficients and indexes. We revealed that soils were contaminated with metals substantially greater in Severodvinsk than in two other cities. Aggregated hazard indexes calculated for combined introduction of contaminants from soils didn't exceed 1.0. Contaminants from soils primarily enter a body via oral introduction. A contribution made by oral introduction into a total dose for examined toxicants amounted to 68-79 % at the median level among children and adults. Overall individual carcinogenic risk in Severodvinsk was higher than in two other cities and amounted to 9.1•10-4 and 2.3•10-3 at the median level and 90%-percentile one accordingly. Non-carcinogenic and carcinogenic risks caused by exposure to contaminants in soils are acceptable when taken in their median concentrations.

“…Soil is a most significant component in the environment; it accumulates chemicals and causes secondary contamination of ambient air and water [1,2]. Chemicals occur in soil mostly due to discharges and emissions from industrial enterprises, motor transport, communal and industrial wastes [3][4][5][6][7].…”

“…PAHs absorption from soils through roots of agricultural plants makes for their penetration into food chains with agricultural products and the process has an apparent biomagnification effect. Besides, soils act as the secondary contamination source for ambient air and water by accumulating these pollutants quite actively [27]. Therefore, results produced by monitoring of 3,4-ben(a)pyrene concentrations in urban soils are highly informative integral indicators for creating an objective hygienic and environmental profile of a territory within social and hygienic monitoring activities and environmental analytics [28].…”

Assessment of carcinogenic risk caused by elevated 3,4-benz(a)pyrene concentration in soils in an industrial city

Apparent destructive changes in soils typically occur in residential areas within urbanized ecological systems formed in large industrial cities. Elevated concentrations of super-toxicants and xenobiotics in soils, polycyclic aromatic hydrocarbons included, create high potential health risks for city population. Our research goal was to assess the carcinogenic risk caused by elevated 3,4-benz(a)pyrene concentrations in soils in Taganrog, an industrial city with its population being about 250 thousand people located in Rostov region. The assessment included individual and population risks. There are two basic reasons which make the research vital. First of all, 3,4-benz(a)pyrene contents in soils in residential areas exceed hygienic standards. Secondly, the incidence of malignant neoplasms has been stably high in the city. We analyzed the results of determining 3,4-benz(a)pyrene concentrations in 384 soil samples taken in 2013–2020 at 19 monitoring posts (located within residential areas close to crossroads with intense traffic, recreational zones, and areas around preschool children facilities). 3,4-benz(a)pyrene was established to be the priority pollutant in soils in the city with its share contribution to the complex pollution index (Csoil) being 55.25 %. 3,4-benz(a)pyrene concentrations were higher than maximum permissible ones in 65.63 % of all the examined soil samples; its average and maximum concentrations were equal to 2.298 and 45.525 MPC accordingly. We assessed the individual multi-route carcinogenic risk (CR) caused by elevated 3,4-benz(a)pyrene concentrations in soils. The risk turned out to be high (2.4606•10–3) and inhalation introduction was established as the priority one (94.84 %).

“…Являясь важнейшим компонентом окружающей среды, почва аккумулирует химические вещества и выступает источником вторичного загрязнения атмосферного воздуха и воды [1,2]. Основными источниками поступления химических веществ в почву являются выбросы и сбросы промышленных предприятий, автотранспорт, бытовые и производственные отходы [3][4][5][6][7].…”

Проведен сравнительный анализ загрязнения почвы химическими веществами в городах Арктической зоны Архангельской области и оценка риска здоровью населения при воздействии контаминантов почвы в условиях селитебного сценария. Актуальность исследования определена тем, что Архангельская область входит в число субъектов Российской Федерации с наибольшей долей проб почв селитебных территорий с превышением гигиенических нормативов по санитарно-химическим и микробиологическим показателям. В основе оценки-данные мониторинга химического загрязнения почв селитебных территорий в городах Арктической зоны Архангельской области (Северодвинске, Архангельске и Новодвинске) за 2007 2017 гг. Оценена экспозиция населения контаминантами почвы при их поступлении пероральным и накожным путем. Определены уровни риска для здоровья детского и взрослого населения. Для изучения неканцерогенных эффектов использован подход референтных доз, рассчитаны коэффициенты и индексы опасности. Установлено, что загрязнение почвы металлами в Северодвинске значительно выше, чем в других городах. Значения суммарных индексов опасности при комплексном поступлении химических веществ, загрязняющих почву, не превышали 1,0. Пероральный путь является основным путем воздействия загрязняющих почву веществ. На уровне медианы вклад перорального пути в суммарную дозу для исследуемых токсикантов среди взрослого и детского населения составил 68-79 %. Суммарный индивидуальный канцерогенный риск в Северодвинске выше, чем в других городах, и составил на уровне медианы и 90-го процентиля 9,1•10-4 и 2,3•10-3 соответственно. Неканцерогенный и канцерогенный риски при воздействии контаминантов почвы на уровне медианных концентраций являются допустимыми. Ключевые слова: загрязнение почвы, химические вещества, почва селитебных территорий, превышение гигиенических нормативов, оценка риска, уровень риска.
