A toxic smoke plume generated by the large fire that broke out on Saturday, July 4, in Oraiokastro, near Thessaloniki, has spread over a vast area, raising concerns among scientists and public health experts.
Researchers warn that the plume could pose significant health risks, particularly for vulnerable groups such as children, older adults and people with pre-existing respiratory conditions. They are advising residents in affected areas to wear protective masks and minimize exposure to outdoor air where smoke is present.
Aristotle University of Thessaloniki is expected to publish detailed analyses of the plume’s chemical composition in the coming days. Meanwhile, authorities have instructed residents to keep windows closed and refrain from using high-pressure water hoses to clean outdoor surfaces, warning that the practice could resuspend hazardous particles and increase airborne exposure.
Although the fire in Oraiokastro has been brought under control and no active fire front remains, the burning of industrial and recyclable materials generated the toxic smoke cloud. Preliminary assessments indicate that the plume has traveled hundreds of kilometers and may have reached as far south as the Attica region and the Peloponnese.
