Scientists have found that smoke from large -scale forest fires that occurred in Canada in 2023 caused premature death of 82 100 people around the world.
researchers from Canada, the USA and China, using satellite observations and various computer models, studied global and regional air pollution for human health caused by forest fires that occurred in Canada In the period from May to September 2023.
, according to the results of the study, scientists came to the conclusion that the smoke from Canadian fires, which reached the northeastern states of the United States and the western coast of Europe, led to premature death 82,100 people around the world. At the same time, 64 300 fatal outcome came to North America and Europe. And about 5,400 sudden deaths in the USA and Canada, which took place from June 26 to July 7, 2023, when the concentration of smoke reached the highest level, are directly related to these fires.
Scientists also found that Prolonged fires provided approximately 13 % of the global effects of the fine particles (PM2.5) that occur during fire, increasing their annual average content by about 0.17.
Scientists note that the resulting data demonstrates the fact that even in one year forest fires can have a serious effect on the global carbon cycle, ecosystem, the quality of air and health, the quality of air and health, the quality of air and health. people. According to scientists, the results of the study are a warning for regions that are not accustomed to long or repeated effects of smoke from fires.
researchers emphasized that Climate change can strengthen the negative impact of forest fires on health, and early warning systems, air quality predictions and international cooperation play a critical role in protecting people from smoke.
The study is published in the journal Nature. >
2023 forest fires in Canada became the largest in the history of the country and were among the most large -scale in the world over the past in the world in the world Decade.
