More than 1,000 Connecticut children under age 6 were reported poisoned by lead in 2020, according to a report released this week by the state Department of Public Health (DPH).
Of the children tested that year, 649 were new cases.
As has been the case for many years, nearly half of the 1,024 lead-poisoned children lived in the state’s cities. New Haven had the highest number of lead-poisoned children, with 171, followed by Bridgeport, 148; Waterbury, 81; Hartford, 71; and Meriden, 35. These five cities had 49% of all lead-poisoned children in Connecticut in 2020.
Following suit, health disparities also continued. Black and Hispanic children continued to have higher rates of lead poisoning than non-Hispanic white children. Non-Hispanic Black children were 2.6 times more likely to be poisoned than white children, according to a report on the 2020 lead poisoning numbers on the state’s Open Data website.
DPH Commissioner Manisha Juthani, M.D., said Tuesday, “Protecting the youngest residents of our state from lead poisoning is a priority for DPH. And even though the numbers show that we are heading in the right direction, our work — including linking families to vital resources and building awareness in our inner cities — is far from done.”
EDITOR’S NOTE: The legislature is currently considering the Lamont administration’s proposed budget adjustment, which includes HB 5045 An Act Reducing Lead Poisoning.
But these latest numbers are based on a calculation that the U.S. Centers for Disease Control and Prevention (CDC) and the state have used since 2012. That calculation defines lead poisoning as 5 micrograms of lead per deciliter of blood in a child’s body.
In October, the CDC lowered its definition of lead poisoning to 3.5 micrograms per deciliter.
If the state had used the CDC’s new measurement, or “reference value,” the number of Connecticut children considered lead poisoned would triple, to 3,000.
Even without the CDC’s adjustment, the pandemic complicates how to compare the numbers released to those from earlier years.
The DPH says in its report that “there was a sharp decline in screening” in April 2020, a month after the country started shutting down. A total of 61,700 children in Connecticut received lead blood tests in 2020, compared with 72,000 in 2019 and 73,000 in 2018. In addition, less than 60% of the state’s children under 3 years old were tested twice, as required by state law.
Although lead poisoning is notoriously linked to the water crisis in Flint, Mich., in 2014, lead poisoning in the Northeast and in other older parts of the country is usually the result of deteriorating interior and exterior house paint.
For close to a century, before the federal government finally banned its use in 1978, lead was added to paint to increase its durability. Although walls may be painted over, chips from the degrading paint can be leaded. Of particular concern is leaded paint dust, created as paint breaks down and is left behind when doors and windows of older homes are opened and shut.
Babies and toddlers are particularly vulnerable to deteriorating paint because they are close to the ground and their breathing rates are higher than that of adults. And, as any parent knows, young children typically explore their new worlds, quite literally, through hand-to-mouth activities, turning a floor with leaded paint chips and leaded dust into dangerous terrain.
Exposure to the heavy metal, particularly during these early years when children’s brains are developing, can cause permanent cognitive damage, including an irreversible loss in IQ points. The toxin is also linked to speech and developmental delays, hearing loss and hyperactivity.
In addition to the 2020 numbers, DPH this week issued the numbers of lead-poisoned children in 2019 – 1,188; and 2018 — 1,333.
