The Portuguese Environmental Protection Agency (APA) clarified on Tuesday that particle levels in the Portuguese mainland and the Azores “do not yet show” the impact on the surface of a cloud of smoke generated from fires in Canada.
In the clarification, the APA refers to the fact that particle levels measured by air quality index classes remain at Good and Very Good levels in mainland Portugal and the Azores.
On Monday, the Portuguese Institute of the Sea and Atmosphere (IPMA) said that a cloud of smoke particles from fires in Canada had affected the Azores from Sunday and should then spread to the mainland.
According to the IPMA, the concentrations of these pollutants are below legal limits and therefore should not pose a threat to human health.
On Tuesday, the APA explains that through the QualAr system, it continuously monitors data measured at all stations in the country, in near real time.
“According to data measured at various stations in the Portuguese mainland and the Azores, there are particle levels to date that do not yet show the effect on the surface of the cloud of smoke from fires in Canada, maintaining an order of magnitude of the levels measured in air quality index classes” Good” and “Very good,” the agency said in a statement.
The APA also mentions that the Madeira archipelago has been experiencing an episode of particle and natural dust transport from Monday, originating from the arid desert regions of North Africa, and continuing through this Tuesday, however “the measured levels did not exceed the limit value for protecting human health and do not pose a problem for public health”.
The wildfires that have plagued Canada for weeks have released significant amounts of gases and particles into the atmosphere that are carried and dispersed by the winds.
“The cyclonic circulation associated with the depression centered northwest of the Azores will contribute to the large-scale transport of these pollutants, mainly carbon monoxide, along the North Atlantic, which reached the Azores region last Tuesday, June 13,” it said. message. IPMA.
Thousands of firefighters from several countries around the world, including Portugal, are fighting active fires in Canada, with the province of Quebec being the most affected region.
