Air Pollution in Serbian Cities: Sources, Health Risks, and Ways to Improve Urban Air Quality

Air Pollution in Serbian Cities
This article examines air pollution in Serbian cities with a focus on changes in pollutant composition, dominant emission sources, and associated health risks. Using examples from major urban centers, it highlights how particulate matter, nitrogen dioxide, sulfur dioxide, and ground-level ozone interact to create complex urban air pollution patterns. The paper also outlines policy-relevant pathways for restoring urban air quality through energy transition, sustainable transport, and integrated environmental monitoring.

Sustainable Development and Climate Challenges: The Crucial Role of C:N:P Stoichiometric Ratios for Effective Ecosystem Management

Stoichiometric Ratios
Climate change threatens the balance of Earth’s biogeochemical cycles. The stoichiometric ratios of carbon, nitrogen, and phosphorus (C:N:P) shape ecosystem resilience, carbon sequestration, and nutrient flows. Human activities, such as intensive farming and the use of fossil fuels, distort these ratios, accelerating greenhouse gas emissions and soil degradation. Integrating stoichiometric principles into climate and land-use policies can strengthen ecosystem services, biodiversity, and long-term sustainability.
