chemicals that we can use in refrigeration.
Those chemicals were put in the firefighting equipment, for example.
They were very effective at that.
They were put in the aerosols, sprays.
And so they've been used for fumigation of the vegetables and the fruits.
So they were working really well.

Well, the atmosphere has these mixing properties.
You know, there are a lot of exchange between the troposphere and stratosphere and the tropics.
Oh.
And they can travel also with this flow of the air from the tropics into the middle latitudes in the polar region.
There is the so-called Brewer-Dobson circulation in the atmosphere.
