And we know how nanoparticles, because they have a larger surface area, can be more problematic.

They also can probably go straight up into the brain.

And or across the pulmonary tissues.

And so those small particles we should be particularly worried about.

But it's been such a long journey to try to figure out how to get that out of aircraft.

It's a problem.

The EPA recognize it.

They said it's an endangerment, but the industry is still pushing back.

Yeah, that study, particularly this was by Alex Hollingsworth, was particularly looking at people over 65.

And we're working on a follow-up study that will look at

people below 65, but it was quite striking when NASCAR took lead out of their fuel, he compared the rates of coronary heart disease of people that live nearby compared to a control group populations that live further away.

And he did see a pretty striking reduction.

One of the things we also want to find or look at in our follow-up is how quickly does that risk begin to taper off?

That's going to be really important in terms of trying to develop a strategy around preventing lead poisoning.

How quickly do we expect to see it fall?

I think it's probably going to be within 12 to 24 months that we'll see benefits.

Oh, yeah, absolutely.

You can get those in any hospital, any clinic across the country.

We're still struggling with having those available where it's most needed in the industrializing countries, but certainly available here.

Now, we don't expect that for most people who have those symptoms, lead poisoning is going to be the cause.
