How pollution migrates across borders: ozone, dust and smoke
Original: The migration routes of pollution: How ozone, Saharan dust and wildfire smoke cross borders
Air pollution does not stay where it is produced. Ozone, Saharan dust and wildfire smoke travel long distances across national borders, following what can be described as migration routes of pollution. This means that air quality in one country is often shaped by emissions and natural particles originating far away, complicating efforts to monitor and control pollution regionally.
Why now: Saharan dust events and wildfire smoke affecting multiple countries at once have drawn attention to how airborne pollution ignores borders.
