It looks to me people should be more concerned about what they put in their cars than burning cathedrals...



Leaded petrol has been banned for over 20 years.

The story of tetraethyl lead is quite a fascinating one actually.

Do you have any evidence for that slander?

“Who Will Invade Brazil to Save the Amazon?”, Asks U.S. Magazine Foreign Policy
For Harvard professor Stephen M. Walt, "it's only a matter of time" before the international community intervenes in the largest tropical forest in the world. And since Brazil isn’t a true great power, threatening it with either economic sanctions or even the use of force might be feasible.

I think the world should do it . Stop selling them chainsaws and have the military destroy all the bridges the logging trucks use.

"Petrol" Ah, looks like you're in the UK where leaded gas has been banned for 20 years as you say :)
Some countries still uses leaded gasoline though as do some aviation engines. Tetraethyl lead seems to be the main contributor to lead pollution in the air.

Anyway, it is quite amazing the amount of lead that was released with just a tankfull.

Piston aircraft fuel and resulting car fuel contamination ...

"Despite the widespread belief that the federal government banned lead from automotive gasoline two decades ago, a little known federal regulation allows unleaded gasoline to contain trace amounts of the toxic metal. Experts say it contributes to environmental contamination and harms children, particularly those living in traffic-congested urban areas."

"The regulation doesn’t allow lead to be added intentionally to gasoline, but does permit unleaded gasoline for motor vehicles to contain up to .05 grams of lead per gallon. This is to account for accidental cross-contamination with lead in the gasoline distribution system, which may carry leaded aviation gasoline via the same pipeline, according to a spokeswoman for the Environmental Protection Agency [EPA]."

“If you’re talking about .05 grams per gallon, that’s one heck of a lot of lead when you pay attention to the number of gallons being consumed,” said Mielke, an urban geochemistry and health expert who teaches in the department of pharmacology at Tulane University’s School of Medicine.

Well, they found some of the lead.
But not enough to worry about.
