Ambient air quality assessment in the Kremenchuk Territorial Community based on the environmental risk concept

Tеtiana Ryhas, Volodymyr Shmandii
Abstract

Under conditions of urban transformation and increasing anthropogenic pressure, the assessment of ambient air quality and associated environmental risks is becoming increasingly important. A significant role in the formation of environmental hazards is played by short-term peaks in pollutant concentrations, which are often not taken into account by conventional monitoring methods. The aim of this study was to substantiate an approach to the operational assessment of environmental hazard states of ambient air at the territorial community level, taking into account natural and anthropogenic factors. The study employed methods of logical analysis of scientific research findings, system analysis of factors influencing air quality formation, elements of mathematical modelling of pollutant dispersion processes, and a risk-oriented approach to assessing the impact of pollution on the population. The concept of natural-anthropogenic fluctuations in ambient air quality within a territorial community was substantiated, taking into account natural factors, emergency and war-related events, and anthropogenic hazard sources. An Increased Environmental Risk Index (IER) was introduced as an analytical indicator for assessing the short-term effects of air pollution on public health. An integrated model for environmental assessment was proposed, combining mathematical modelling (Gaussian, jet, and energy models) with instrumental measurements. Regularities in the formation of local zones of ingredient and acoustic pollution under conditions of intensive use of individual power generators were identified. The proposed approach makes it possible to promptly identify periods of increased risk and assess the spatial heterogeneity of environmental hazards. The obtained results may be used by local authorities to improve ambient air monitoring systems, develop measures for managing anthropogenic pressure, and implement early warning mechanisms for informing the population about increased levels of environmental hazard
