Persistent pollution - there is a whole class of pesticides: herbicides, fungicides, insecticides, etc. That use complex chlorinated hydrocarbons, that stay in the environment, in various forms, and which often degrade into more toxic, and more persistent (survive longer) versions.
For example there is more DDT in glacier runoff water now, than there was in the 70s and 80s, even though it hasn't been used since then.
The story is complex, and goes on, and on.
- sp332 5y agoThe ones listed in the actual article aren't that, though. NOx is down dramatically. Remember acid rain?
- pomian 5y agoYes indeed. I think the whole air pollution question is a distraction to the bug problem. (Rather an addition to?) There are serious issues with modern gasoline, and it's byproducts of combustion, though. All together there are a lot of pollutants which we need to clean up, still ongoing. It's a huge problem.
