There's an analogous horizontal phenomenon. Just as the deep oceans are gravitational sinks, the poles are thermal sinks. Cold traps. And so concentrations of persistent atmospheric pollutants are substantially higher there. So it goes.
- darkerside 6y agoDo solar winds do anything to strip these pollutants away?
- at_a_remove 6y agoI would not think so. Most of these pollutants are "heavy" and solar winds are only appropriate for the less dense molecules, unfortunately.
- mirimir 6y agoSorry, I neglected to say that they get deposited through precipitation, and incorporated into ecosystems. As I recall, this is mostly about persistent lipophilic organics, some of which are endocrine disruptors. Concentrations are amazingly high in humans (north) and wildlife (north and south).
