Hello, so today we're going to be talking about primary and secondary pollutants.
00:06
So what exactly is the difference between those two? well, primary pollutants are pollutants that are directly emitted.
00:32
So like an example of this, if you think about cars, would be nitrogen oxide and carbon monoxide, those kinds of pollutants.
00:47
And then there's something called secondary pollutants.
01:03
And so secondary pollutants are basically, they're indirectly admitted.
01:11
So they form from primary pollutants.
01:34
So they're formed from the primary pollutants, like say ozone.
01:40
Ozone isn't directly emitted by cars, but after the car is it really, release these pollutants, they react with each other's, volatile organocarpons bounds 2 for primary.
01:56
They react and they form ozone...
