Ragweed pollen can remain airborne for days and travel great distances, and can even be carried 300–400 miles (500–600 km) out to sea. [12] Ragweeds native to the Americas have been introduced to Europe starting in the nineteenth century and especially during World War I , and have spread rapidly since the 1950s. [ 15 ]
