Trajectory of air quality in Ukraine.

In the course of Russia's war on Ukraine, fierce forest fires, burning of oil and ammunition depots and destruction of urban and industrial areas have spread hazardous combustion products far and wide and are accelerating global heating. Measures to stabilise the national environmental situation, and to prevent a larger-scale ecological disaster, should combine the efforts of managerial, regulatory and practical efforts, with priority given to preventive measures. There is need for improved methodology for assessing environmental loss and damage, as well as the procedures to bring the perpetrators to justice. In the absence of a unified national system of monitoring air quality, we consider the opportunities for adopting an effective monitoring system. [ABSTRACT FROM AUTHOR]
