Air Quality in Jelgava: Impacts of Industrial Operations

Air pollution in urban areas remains a critical challenge, particularly in densely populated cities. Industrial activities contribute significantly to air quality deterioration through the emission of heavy metals and trace elements that pose risks to human health and the environment. This study investigates the spatial variability of air pollution in Jelgava, Latvia, with a focus on areas impacted by industrial emissions. Snow samples were collected across the city to monitor air pollution, with analyses targeting metals such as lead, arsenic, nickel, copper, zinc, and cadmium. Using cluster analysis, regions were categorized by pollution intensity, uncovering distinct spatial patterns. Results indicate that industrial zones and areas near major roadways exhibit significantly elevated concentrations of toxic metals, often exceeding regulatory thresholds. Seasonal variations, particularly increased emissions from winter heating, were found to exacerbate pollution levels. These findings underscore the importance of continuous monitoring, stricter regulations, and targeted pollution control measures to mitigate health risks and environmental impacts. The study emphasizes the need to integrate pollution management into urban planning and public health policies, providing a foundation for informed decision-making and sustainable urban development. By identifying pollution hotspots, this research provides a foundation for informed decision-making to minimize health risks and promote sustainable urban development in Jelgava. Additionally, the use of snow sampling as a cost-effective and practical method for monitoring airborne pollutants offers valuable insights for other cities facing similar challenges.
