Lead Dust Is Linked to Violence, Study Suggests

Science Daily -- Childhood exposure to lead dust has been linked to lasting physical and behavioral effects, and now lead dust from vehicles using leaded gasoline has been linked to instances of aggravated assault two decades after exposure, says Tulane toxicologist Howard W. Mielke.

Vehicles using leaded gasoline that contaminated cities' air decades ago have increased aggravated assault in urban areas, researchers say.

The new findings are published in the journal Environment International by Mielke, a research professor in the Department of Pharmacology at the Tulane University School of Medicine, and demographer Sammy Zahran at the Center for Disaster and Risk Analysis at Colorado State University.

The researchers compared the amount of lead released in six cities: Atlanta, Chicago, Indianapolis,

apiergallini Veteran Author North Carolina Posts:389 Points:244,255 Joined:Mar 2011	Message Posted: Apr 28, 2012 4:03:33 PM Ignore apiergallini Report Abuse @johntxx At one point, we didn't know that radiation was dangerous. We didn't know that thalidomide caused birth defects. We didn't know that mercury caused brain damage. Someone, somewhere, performed studies and figured those things out, and now we know, and we're better off for it. Even if you don't believe that lead dust causes problems with people's levels of violence (though who are you to question these doctors and scientists and say their findings are wrong?), it's pretty much universally accepted that lead is dangerous if ingested or absorbed. How do you think we figured THAT out? Probably another one of those "worthless" studies, funded by a "research grant."

They used to say it was the cartoons we watched, also a load. Who pays for this junk? Oh yeah, I do as a tax payer funding completely useless "research" grants like this one. Now there's something to get your blood pressure up. Maybe we need a study on that--not.

Look to see the political agenda of the researcher. Check for other contributing factors. There are more variables than can be listed in a thesis. Coincidental events like 'eating carrots' can be used by stupid so-called researchers looking through their political agenda glasses to make a case for any demon. I know I'm right and I'll beat the living dung out of anyone who disagrees with me.

aquarinut Champion Author British Columbia Posts:1,628 Points:436,005 Joined:Jul 2011	Message Posted: Apr 27, 2012 11:02:39 PM Ignore aquarinut Report Abuse Yeah right... have a tough time with this one.... Absolutely nothing to do with the: 1. Korean conflict 2. Vietnam conflict 3. Rise in population 4. Increase in drug use 5. Increase in alcohol use 6. Increase in gangs and gang associations 7. Television access to media hype and taking as gospel truth 8. Hollywood becoming the real life and real life becoming "history" 9. Exponential growth of graphic and violent video games/movies 10. Unemployment... 7% in 1950 is nothing compared to 7% in 1985!! 11. "Inner" city population growth with little to no chance of getting out. 12. Lighter sentences due to a "legal" rather than a "justice" system 13. Heavy swing from "I should do something" to "I saw nothing" 14. police/security resources lagging behind population growth 15. General public knowledge of police/security response is limited etc, etc, etc... the list goes on and on!!! Wonder what Mielke is going find and publish in this day and age where rapes, beatings, riots and murder are now shown through the exponentially expanding internet and "smart" cell phone social networking? Must be due to the lead exposed to the developers of this new cyber means of communications and all those who follow it! Guess I must have been effected as well. Posting this reply electronically...

So eat a diet that helps flush them out if you live in urban areas that were effected by this stuff. But be real careful you don't use this as an excuse for bad behavior.
