Research Links Lead Exposure, Criminal Activity

Rudy Giuliani never misses an opportunity to remind people about his track record in fighting crime as mayor of New York City from 1994 to 2001.

"I began with the city that was the crime capital of America," Giuliani, now a candidate for president, recently told Fox's Chris Wallace. "When I left, it was the safest large city in America. I reduced homicides by 67 percent. I reduced overall crime by 57 percent."

Fairfax economist Rick Nevin has spent more than a decade researching and writing about the relationship between early childhood lead exposure and criminal behavior later in life.

A recently released study concludes that there is a strong association between preschoolers' blood lead levels and crime rates 19 years later, when the preschoolers grow up. Declines in lead levels in several industrialized countries corresponded with later drops in crime rates, the study says.

Although crime did fall dramatically in New York during Giuliani's tenure, a broad range of scientific research has emerged in recent years to show that the mayor deserves only a fraction of the credit that he claims. The most compelling information has come from an economist in Fairfax who has argued in a series of little-noticed papers that the "New York miracle" was caused by local and federal efforts decades earlier to reduce lead poisoning.

The theory offered by the economist, Rick Nevin, is that lead poisoning accounts for much of the variation in violent crime in the United States. It offers a unifying new neurochemical theory for fluctuations in the crime rate, and it is based on studies linking children's exposure to lead with violent behavior later in their lives.

Lead sucks!

But at least now all children are required to be screened for lead level (at least in my state) upon enrollement to school and all houses sold need to have a disclosure about lead based substances. If your renting and you have kids, check that stuff out and clean your window sills regularly!

Lead sucks!

Strange... There was a program on yesterday about lead poisoning in roman times. It went into how the romans loved to make things out of lead and how it affected them. Guess it made them into some of the fiercest warriors the planet has seen. Anyway.. blah blah..

Here is an interesting read. Apparently the first law banning lead was to do with economic reasons!!! why does that not surprise me.

The long-term effects of exposure to low doses of lead in childhood. An 11-year follow-up report

HL Needleman, A Schell, D Bellinger, A Leviton, and EN Allred


Abstract

To determine whether the effects of low-level lead exposure persist, we reexamined 132 of 270 young adults who had initially been studied as primary school-children in 1975 through 1978. In the earlier study, neurobehavioral functioning was found to be inversely related to dentin lead levels. As compared with those we restudied, the other 138 subjects had had somewhat higher lead levels on earlier analysis, as well as significantly lower IQ scores and poorer teachers' ratings of classroom behavior. When the 132 subjects were reexamined in 1988, impairment in neurobehavioral function was still found to be related to the lead content of teeth shed at the ages of six and seven. The young people with dentin lead levels greater than 20 ppm had a markedly higher risk of dropping out of high school (adjusted odds ratio, 7.4; 95 percent confidence interval, 1.4 to 40.7) and of having a reading disability (odds ratio, 5.8; 95 percent confidence interval, 1.7 to 19.7) as compared with those with dentin lead levels less than 10 ppm. Higher lead levels in childhood were also significantly associated with lower class standing in high school, increased absenteeism, lower vocabulary and grammatical-reasoning scores, poorer hand-eye coordination, longer reaction times, and slower finger tapping. No significant associations were found with the results of 10 other tests of neurobehavioral functioning. Lead levels were inversely related to self-reports of minor delinquent activity. We conclude that exposure to lead in childhood is associated with deficits in central nervous system functioning that persist into young adulthood.
