The results indicated that the closer children resided to this particular airport, the greater the probability their blood lead level would exceed the California Department of Public Health (CDPH) threshold– which is 4.5 micrograms per deciliter.
The researchers also noted that the children who lived east– or downwind– of the airport had much higher blood lead levels and that children’s lead levels increased when there was higher piston-engine aircraft traffic. Likewise, when the airport sold greater quantities of leaded aviation gasoline.
Among children who lived at least one mile or further away from the airport, the probability of blood lead levels exceeding the CDPH threshold was over 21% lower than the children who resided within half a mile.
Finally, in regards to geographic location, the children who lived east of the airport were over two times more likely to have blood lead levels about the threshold.
So now, the researchers are confident that their study results represent a dire need for policy change that specifically targets the aviation industry.
“Across an ensemble of tests, we find consistent evidence that the blood lead levels of children residing near the airport are pushed upward by the deposition of leaded aviation gasoline,” said Sammy Zahran, the study’s lead author.
“This indicates we should support policy efforts to limit aviation lead emissions to safeguard the welfare of at-risk children.”
