Solid CFDNPs in air pollution are characterized by the abundant presence of strongly magnetic, iron-rich particles which condense and/or oxidize upon airborne release, often retaining a rounded or spherical shape as they cool. Erythrocytes were identified transferring ‘hitchhiking’ NPs to activated endothelium. Cross, Imad A.M.
Many countries regulate ozone because of the damage the pollutant does to plants and people. Since the 1990s, tighter controls on emissions of those ingredients have lessened ozone pollution in many European and US cities. The researchers think the harmful effects of surface ozone pollution are much less recognized.
