FAKE NEWS for the Zionist agenda WEDNESDAY, April 25 (HealthDay News) — Urban areas contaminated
decades ago by airborne lead dust now face an increased incidence of
aggravated assault, according to a new study.
The surge in violence is linked to exposure to the lead dust emitted
from older vehicles that ran on leaded gasoline, according to the
researchers, who say improper handling of lead-based paint could have
played a role as well.
“Children are extremely sensitive to lead dust, and lead exposure has
latent neuroanatomical effects that severely impact future societal
behavior and welfare,” said study co-author Howard Mielke, a research
professor in the pharmacology department at the Tulane University School
of Medicine, in a Tulane news release.
The researchers compared the amount of lead released from 1950 to 1985
in Atlanta, Chicago, Indianapolis, Minneapolis, New Orleans and San Diego.
Exposure to lead dust in the air surged during that time period because
of the use of leaded gasoline, the study found. Two decades later, rates
of aggravated assault in those cities increased as well. Exposure to lead
dust had negative effects on children’s behavior as adults, according to
the researchers, who said the association held true even after they took
other factors into consideration, such as household income and
education.
The current rate of aggravated assault rose by almost one-half of a
percentage point for every 1 percent increase in tonnages of environmental
lead that was released more than two decades earlier, the study found.
“Up to 90 percent of the variation in aggravated assault across the
cities is explained by the amount of lead dust released 22 years earlier,”
Mielke said in the release.
The study is published online, ahead of print publication in the August
issue of the journal Environment International.
While the study found an association between lead contamination and
future violence, it did not prove a cause-and-effect relationship.
