The phasing-out of lead paint and leaded gasoline is _one_ of the suspected reasons for the US's big drop in violent crime, after the peak of the early 1990s. The US finally banned lead paint in the 1970s.* That same decade, stricter air pollution laws practically required catalytic converters in car exhaust systems -- which began the end of leaded gasoline, since lead in the exhaust would quickly "poison" the platinum catalyst and keep it from doing its job.** By the mid 1990s, children growing up after this change were reaching their teens and 20s -- and had a lot less lead in their bodies than their parents had at that age. * About 50 years after most of Europe already had. Alternatives had already been in use for that entire gap, and new ones (like latex paint) came up in the meantime. ** The job of reacting carbon monoxide, nitrogen oxides, and unburned fuel into less-immediately-harmful things. Lead gets in the way of this.

Interesting, but many details have been left out. It wasn't so much the oil industry that fought for lead, but the Ethyl Corporation, a division of GM. The danger of lead was well know. Back in the 20s NY & NJ were trying to get production banned in those states, but GM appealed to the president, who commissioned a panel of experts (auto industry experts) and they determined that with a few safeguards for workers it was completely safe.Patterson's research had actually been funded in part by GM, but once the results were out GM pressured him to do other research, When he refused GM tried to discredit him and even get him fired. GM started a campaign of science denial,. You know the "not enough is known", "conflicting data", "we need more research", etc, that also was later used by the tobacco industry and even later by the oil industry. Possibly GM started all of the anti-science crap that we deal with every day. BTW, Henry Ford had argued against the use of TEL in gas, and pushed for an alcohol solution for the octane problem with early gas.

Just to correct a detail or two. Ethyl wasn’t a division of GM, it was a company created by GM and Exxon in which they held equal shares. The decision to allow lead in gasoline in the 1920s was made in a process under the Surgeon General (since there wasn’t yet an EPA) in 1925-26, not by the president. Patterson’s confrontation with industry was with Exxon. Yes, there is a tobacco connection. The company b that ended up buying Ethyl in the 1960s from its founders was Albemarle, which produced paper for cigarettes.

Point of order: Lead is not banned in *all* gasoline in the US. Though we are also working that way. Most small planes like the Cessna 172 run on Avgas, usually 100LL. In this case 100 means 100 Octane, and LL mean "Low Lead" (it's about the same amount of lead as car gas in 1973, but lower than historical aviation fuels). It's used for the same reason as Leaded gas was in cars: anti-knock and anti-detonation, which is arguably quite important when in a plane that you want to keep in the air. Piston airplane engines also tend to have much higher compression ratios than car engines because they're working in much thinner air, which is why avoiding pre-detonation is REALLY important. Various ULL (ultra-low lead) and UL (unleaded) aviation fuels are in development some even being certified for widespread use, but it's a slow process because again, can't have planes just falling out of the sky. The end is in sight, but it also isn't here just quite yet. Piston aircraft are generally not allowed to use car gas because the additives may work against the performance of the plane, as well as things like ethanol just completely separating out with the changes in pressure and temperature. Jet planes and turboprops don't have to worry about this because they don't use the four-stroke cycle, and don't have to worry about pre-detonation, they use kerosene based jet fuels (typically Jet A or Jet A1) which are completely lead free.

I think it's important to preface radiometric dating stories with a brief bit about how when crystals form they tend to be pure elements; this is the "reset" that starts the clock, when it crystalized from some melt. Like, finding an atom of argon inside a crystal containing potassium is a giveaway that that argon was not there to begin with. Of course other isotopes might still be present in the original crystal but certain decays are pretty clear. Most of the argon in the atmosphere comes from potassium isotope decay (think bananas)

I just went into a deepdive on leaded gas. Turns out it wasn't completely removed until 1995! (!!!) And it's still used in fuel for aircraft like commercial planes. They also still allow older cars that need some sort of lubrication to add lead to the gas. I always thought it was phased out in the 80's.. So that dang old 50's car that was frequently idling outside my apartment, waking me up with exhaust fumes coming in my window was in fact poisoning me in my sleep. Thanks a lot. I also learned that Algeria phased out leaded gas only in 2021. Honestly so tired of cars.

Most commercial plane run on Jet-A or a similar fuel, which does not have lead in it. Though you are right that most general aviation aircraft (Cessna 150's, 172's, Piper Cubs, etc) have lead in their fuel. This has been an annoyance in general aviation for years now, with a few companies trying to produce a fuel with enough octane to avoid engine damage at higher altitudes. These alternatives have been promising, but the FAA certification process has been quite the challenge.

Anyone else think initially based on the voice this was Keegan Michael Key? Key & Peele going in a whole new direction.

whenever you start talking about fission, you really start being meaningful.

Clair Patterson deserves a Nobel and more recognition. Thank you Clair for making a better tomorrow.

I thought leaded gas went away in the 70s. I didn't realize it was around through to the 90s.

That's some seriously hardcore science to reach that outcome!

WOW! Mind blown. I am really good at science and I'm gobsmacked. Unbelievably good video! I'm hoping you can do a video for my global warming denier friends about the ratio of Carbon-14 in the atmosphere as a result of burning fossil fuels versus Carbon-14 from modern sources, which removes all doubt as to where the hell our greenhouse gases are coming from and the rate in which we are emitting them since the dawn of the industrial age. You just got a new subscriber and I will tell my friends about you. Good job and thank you.

It will be interesting to see the correlation curve with lead and technology advancement in the distant future.

Clair Patterson is the most unsung hero of the 20th Century. He improved the health of millions of people (and billions of animals, probably). And almost no-one knows about him.

I’ve only ever known of Unleaded gas. It’s crazy to me to think that we were still using leaded gas up until I was 3. For some reason it seemed like learning and getting rid of lead in everything happened years before I was even born.

Must have been nice to be an adult in an age (the 1990s...?) where science could force the government to force the petroleum industry to change their practices. How far this country has fallen in such a short span of time
