The severe effects on the environment are a little-known component of the war in Ukraine and a type of "collateral damage" that will stick with us for a very long time. It is undoubtedly less dramatic than the death and damage we are seeing, but it still has significant ramifications that must be acknowledged and dealt with, and every attempt should be taken to avoid it.
For instance, the amount of greenhouse gases produced has increased significantly since the start of the conflict (military armies emit as much carbon dioxide as entire nations), and the fighting that has taken place close to the largest nuclear power plants in Europe, Chornobyl, and Zaporizhian, is raising serious questions about the possibility of radioactive leaks. Our concern also pertains to the contaminated groundwater and the harm it causes to grazing plants and animals.
As a result of the current catastrophic deforestation brought on by bombings and fires, the ecosystem's capacity to maintain homeostasis and fight itself against climate change and air pollution will be compromised.
According to a recent assessment, one-third of Ukraine's agricultural system is already costly due to shortages of corn, wheat, sunflower oil, and fertilizer (and the situation has further deteriorated). According to the World Bank, Ukraine is home to one-third of the planet's most fertile land (Chernozem soil), which can be effectively plowed in 68 percent of cases.
This is the reason why many international experts believe that the ongoing conflict could result in the worst food crisis to hit the world since World War II.
.The use of conventional weaponry and the fires created by the fighting is leading to high levels of air pollution in the form of particulate matter (PM), poisonous gases, and heavy metals. An enormous increase in PMs is caused by explosions, building collapses, tunnel and trench drilling, and more.
It is commonly recognized that air pollution has a negative influence on health, particularly when exposure occurs suddenly. In a conflict zone, air pollution is more likely to cause fatalities than bombs. An elevated risk of hospitalization and mortality has been linked to transient air pollution exposure. According to a recent study on hospital admissions in Poland (which is geographically close to Ukraine and comparable), the relative risks of cardiovascular and respiratory hospitalizations due to an increase in PM10 concentration of 10 g/m3 (PM with a diameter of 10 m) are, respectively, 1.0077 (95% confidence interval [CI] 1.0062-1.0092) and 1.0218 (95% CI 1.0182-1.0253).
The risks of cardiovascular and respiratory hospitalizations are, respectively, 1.0088 (95% CI 1.0072-1.0103) and 1.0289 (95% CI 1.0244-1.033) for a 10 g/m3 rise in PM2.5 (PM of 2.5 m in diameter). At the population level, these estimates are concerning, but they probably understate the situation. Misclassification of the extent of exposure and the effects frequently leads to underestimation. According to estimates from the Copernicus program, PM2.5 concentrations during natural wildfires can reach 500 g/m3. Military operations are also associated with similarly increased levels.
As the exposure-response link exists, the relative risk of hospitalization and other health outcomes rises with increasing concentrations. These are extremely high concentrations (the WHO air quality 24-hour mean standard is 15 g/m3). This ignores the reality that during the conflict in Ukraine, the population is exposed to many air pollution sources, leading to multi pollution.
Pollution And Diseases:
All air pollution sources and any diseases that are connected to them must be taken into account to determine the overall risk more accurately. It's also important to take into account the psycho-social factors that affect how the body reacts to stress. Moreover, among Gulf War veterans, a connection between stress and immunological malfunction was found. Post-traumatic stress disorder patients have persistent systemic inflammation and have poor reactions to environmental disasters such as exposure to air pollutants.
The exposure-response correlations and risk estimations mentioned above should encourage Ukrainian authorities to enact public health protection measures to combat air pollution.
The environmental harm brought on by the Ukrainian conflict will last for many years. Even if the war ended today by a miracle, it would take years to reverse the effects of climate change, soil degradation, and biodiversity loss (Ukraine accounts for 35% of all European continent biodiversity), and it would take a lot of work to rebuild the ecosystem that had been put under so much stress.
Additionally, secondary air emissions of highly toxic substances (such as organic pollutants, polycyclic aromatic hydrocarbons, dioxin, carbon monoxide, and polychlorinated biphenyls), some of which are persistent organic pollutants, are brought on by explosions and the heavy traffic of military vehicles. The long-term impacts of air pollution are also predicted to increase the prevalence of inflammatory chronic illnesses. Attacks on gasoline and fuel storage facilities in Ukraine are expected to have resulted in high peaks in air pollution.
Additionally, the United Nations has noted how the energy crisis brought on by the war has led to a strong drive to use fossil fuels even though the European Commission's "REPowerEU" plan calls for a coordinated effort by EU countries to obtain affordable, safe, and sustainable energy to speed up the green transition. The effects of war on people's health, both directly and indirectly, are profound, especially for vulnerable groups like expectant mothers, young children, the elderly, the sick, individuals from lower socioeconomic strata, migrants, and refugees who are most vulnerable to environmental dangers.
These groups must all be safeguarded. Generally speaking, violent conflicts have a variety of short- and long-term effects on development, physical, economic, and social capital, and consequently, on human health.
In conclusion, well beyond our current capacity to foresee or avoid, the environmental destruction brought on by the war in Ukraine will have severe impacts on pollution levels in the air, water, and land, as well as on the overall ecosystem and biodiversity. To protect the future of Ukraine and the surrounding nations, careful European and international policies will need to be implemented to address the associated hazards to human health.
