'We're using children's blood as detectors': how the US fails with lead exposure Poisoned by their homes: how the US is failing children exposed to lead

Antoinette Catholdi-Dow, a 30-year-old mother of two, first started noticing little bite marks on the window sills in 2015, when her son was about two and a half years old.Antoinette Catholdi-Dow, a 30-year-old mother of two, first started noticing little bite marks on the window sills in 2015, when her son was about two and a half years old.
The window sills were the perfect height to help her toddler pull himself up to stand and walk. Eventually, Catholdi-Dow would enter the room and catch her son nibbling along their edges.The window sills were the perfect height to help her toddler pull himself up to stand and walk.

By this point, her son had already been diagnosed with both autism and pica, which is an eating disorder that causes a person to crave and eat non-food items.By this point, her son had already been diagnosed with both autism and pica, which is an eating disorder that causes a person to crave and eat non-food items.
After a few months of this behavior, her mother-in-law suggested a call to the pediatrician’s office to check his blood for lead, just to be safe. Catholdi-Dow, of Attleboro, Massachusetts, initially dismissed her concerns, but began doing research on the internet about how lead, a neurotoxin, can cause behavioral and developmental problems even at low levels. She also read that old homes, like the one where they lived, could have lead-based paint that poses a hazard to young children when it starts to deteriorate.After a few months of this behavior, her mother-in-law suggested a call to the pediatrician’s office to check his blood for lead, just to be safe.

“They were worried that insurance wouldn’t cover it until his three-year [appointment],” Catholdi-Dow said. “But because I had a reason to believe that it could possibly be lead poisoned at the time, they ended up going ahead and doing it for me.”“They were worried that insurance wouldn’t cover it until his three-year [appointment],” Catholdi-Dow said. “But because I had a reason to believe that it could possibly be lead poisoned at the time, they ended up going ahead and doing it for me.”
When Catholdi-Dow’s son had his first blood lead test, the results came back at 24 micrograms per one tenth litre of blood – almost five times higher than the reference point the US Centers for Disease Control and Prevention (CDC) uses to recommend a lead intervention.

Catholdi-Dow, like many other Americans, likely assumed that lead was a hazard that endangered only previous generations. After all, the federal government had begun reducing lead in gasoline in 1972 and banned its use in paint for homes in 1978.Catholdi-Dow, like many other Americans, likely assumed that lead was a hazard that endangered only previous generations.

Making things more confusing is that the history of the rise of lead in American manufacturing, as well as its eventual phase out, is often framed as a public health victory already won.Making things more confusing is that the history of the rise of lead in American manufacturing, as well as its eventual phase out, is often framed as a public health victory already won.
But this national narrative obscures a horrifying truth about lead, which is that sudden mass exposure can happen anywhere, anytime – as it did in Flint, Michigan when improperly treated water began corroding lead pipes and releasing harmful chemicals into the tap water in 2014. And due to a complex mix of factors including the various competing pressures on physicians and weak regulations about how to report this data, there is no federal system that can quickly identify lead exposure emergencies as they happen.But this national narrative obscures a horrifying truth about lead, which is that sudden mass exposure can happen anywhere, anytime – as it did in Flint, Michigan when improperly treated water began corroding lead pipes and releasing harmful chemicals into the tap water in 2014.

When it comes to lead exposure in America, we still don’t have a clear picture of how many children are being exposed to the neurotoxin and where they are. This leaves hundreds of thousands of children vulnerable to the dangers of lead, and compounds inequality in the form of cognitive and behavioral deficits that can hamper communities for generations.When it comes to lead exposure in America, we still don’t have a clear picture of how many children are being exposed to the neurotoxin and where they are.

“We are currently doing things backwards [by] using children’s blood as detectors of environmental contamination,” said Dr Mona Hanna-Attisha, the pediatrician who famously uncovered elevated levels of lead in her pediatric patients and linked it to a new water source in Flint, Michigan. “The screening that needs to happen is in the environment before children are ever exposed.”“We are currently doing things backwards [by] using children’s blood as detectors of environmental contamination,” said Dr Mona Hanna-Attisha, the pediatrician who famously uncovered elevated levels of lead in her pediatric patients and linked it to a new water source in Flint, Michigan. “The screening that needs to happen is in the environment before children are ever exposed.”
Why lead is so dangerousWhy lead is so dangerous
Lead is a naturally-occuring heavy metal valued for both its affordability and malleability. People have used lead to make cosmetics, drinking and eating vessels, aqueducts and more since the days of Ancient Rome (the word “plumbing” comes from the Latin word for lead, plumbum).

People from the ancient world also knew that coming into direct contact with large amounts of lead was harmful, and linked to forgetfulness, melancholy and insanity. But this didn’t stop manufacturers in America and other countries from using lead compounds in pipes, paint, food cans and gasoline at the turn of the twentieth century.

All of these industrial uses put lead particles in the air, in homes and in food and water. In Europe, France, Belgium and Austria were among the first countries to ban it in interior paints in 1909.All of these industrial uses put lead particles in the air, in homes and in food and water.

By 1924, independent American scientists understood that lead in gasoline posed a lethal hazard to the workers making gas, as well as a more subtle but chronic danger for people breathing in car exhaust and factory emissions.By 1924, independent American scientists understood that lead in gasoline posed a lethal hazard to the workers making gas, as well as a more subtle but chronic danger for people breathing in car exhaust and factory emissions.
But it wasn’t until the early 1970s that Congress overcame intense industry opposition and began slowly banning the use of lead-based paint in federal housing, removing lead from gasoline and setting limits on the element in drinking water. It was a long process; lead wasn’t completely banned from gasoline until 1996.But it wasn’t until the early 1970s that Congress overcame intense industry opposition and began slowly banning the use of lead-based paint in federal housing, removing lead from gasoline and setting limits on the element in drinking water.

The US is still grappling with how to remove lingering lead from the environment. Last Friday, the Environmental Protection Agency finalized new regulations that would drastically cut the levels of acceptable lead in dust in public housing, hospitals and schools built before 1978.The US is still grappling with how to remove lingering lead from the environment.

Scientists would eventually discover that lead exposure during childhood can destroy brain cells, disrupt communication between neurons and shrink the prefrontal cortex, which is the part of the brain that helps with complex decision making, emotion and aggression regulation and impulse control.Scientists would eventually discover that lead exposure during childhood can destroy brain cells, disrupt communication between neurons and shrink the prefrontal cortex, which is the part of the brain that helps with complex decision making, emotion and aggression regulation and impulse control.
National, chronic lead exposure in the US has been linked to everything from a significant loss of IQ points to a rise in violent crime to billions of dollars lost in future earnings and tax revenue. There is no “safe” level of lead, and its effects are irreversible. The only treatment that doctors have at their disposal, chelation, is not used except in extreme poisoning cases.

Young American children nowadays have an average blood lead level of about one milligram per one-tenth liter of blood (1 µg/dL). We know this because every year, a small but representative sample of about 5,000 Americans are picked randomly to answer surveys and undergo physical exams that will give health officials an overall picture of the nation’s health – including how much lead is in people’s blood. This sample is known as the CDC’s National Health and Nutrition Examination Survey (NHANES).

The CDC estimates that there are more than half a million children in the US like Catholdi-Dow’s son who have blood lead levels at or above the CDC’s reference value for intervention. They’re concentrated mostly in low-income communities throughout the country because they are the ones who are most likely to live in substandard housing. An estimated 23m housing units in the US have at least one lead-based paint hazard – 3.6 million of which are homes for children under six years old.

Making matters even worse is that the US does not have a robust surveillance system that can find these at-risk children and track potential emergencies like the 2014 one in Flint, Michigan, said Eric Roberts, a research scientist specializing in lead exposure at Public Health Institute, a non-profit health research organization.

Indeed, the Flint, Michigan lead exposure crisis was uncovered by concerned citizens, local pediatricians like Hanna-Attisha and independent scientists.Indeed, the Flint, Michigan lead exposure crisis was uncovered by concerned citizens, local pediatricians like Hanna-Attisha and independent scientists.
This is because not all states require pediatricians to measure blood lead levels in children or report them to county or state health departments. These results, in turn, may or may not get reported to the CDC. That means that the CDC’s most up-to-date local data can’t be used to identify short-term trends or make generalizations about childhood lead exposure at the local, state or national level.This is because not all states require pediatricians to measure blood lead levels in children or report them to county or state health departments.

In fact, Roberts estimates that less than 20% of all young children are tested for lead, no matter what kind of insurance they have, and this screening only identifies about 60% of children with elevated blood lead levels in the US. This estimate, which is the only comprehensive analysis on the subject, is based on numbers from the previous decade.In fact, Roberts estimates that less than 20% of all young children are tested for lead, no matter what kind of insurance they have, and this screening only identifies about 60% of children with elevated blood lead levels in the US.

“I know that in the public health establishment we’re very pious about our belief that lead exposure is bad and protecting kids is good,” Roberts said. “But I don’t see us making an honest effort to make sure that all the kids are lead free.”“I know that in the public health establishment we’re very pious about our belief that lead exposure is bad and protecting kids is good,” Roberts said. “But I don’t see us making an honest effort to make sure that all the kids are lead free.”

But the investment is worth it. Removing leaded drinking water lines, remediating lead paint hazards, eliminating lead from plane fuel and other eradication efforts to protect just the children born in 2018 alone could result in as much as $84bn in future benefits, according to a 2017 analysis from the Pew Charitable Trusts. This money would be in the form of increased revenue and savings to the health care, education and criminal justice systems. While the report didn’t put a figure on the total cost of these repairs, it estimated that it would cost $2bn to replace lead service lines and $18.7bn to deal with lead paint hazards in homes for the 2018 babies.

The federal government is the obvious main funder for this kind of initiative, but Jacobs says that the money should also come from private sources – specifically, the paint and gasoline companies that put all the lead in the environment in the first place. “Companies who caused this problem have to be part of the solution,” Jacobs said. “Everyone else has paid for it except them.”The federal government is the obvious main funder for this kind of initiative, but Jacobs says that the money should also come from private sources – specifically, the paint and gasoline companies that put all the lead in the environment in the first place. “Companies who caused this problem have to be part of the solution,” Jacobs said. “Everyone else has paid for it except them.”

California is the first state to pursue and win this kind of judgement against former lead paint manufacturers. In 2017, the California court of appeals upheld the Santa Clara county superior court decision to hold Sherwin-Williams Company, NL Industries, Inc, and ConAgra Grocery Products responsible for finding and remediating homes with lead paint hazards built before 1951. The US supreme court declined to hear the paint manufacturers’ appeal, and the lead abatement fund is now set at $409m, according to the county of Santa Clara.

While this may seem like a lot of money, it’s nothing compared to what paint companies might have to pay if more jurisdictions begin allowing people with documented lead poisoning to pursue these lawsuits individually.While this may seem like a lot of money, it’s nothing compared to what paint companies might have to pay if more jurisdictions begin allowing people with documented lead poisoning to pursue these lawsuits individually.
In May, a federal jury awarded three Milwaukee men $2m each for lead paint poisoning they suffered as toddlers, to be paid by the paint companies Sherwin-Williams, Armstrong Container Corp and DuPont. The verdict is the first of its kind, and the plaintiffs’ lawyer told the Milwaukee Journal Sentinel that he hopes that the decision “is just the beginning” of a wave of lawsuits.In May, a federal jury awarded three Milwaukee men $2m each for lead paint poisoning they suffered as toddlers, to be paid by the paint companies Sherwin-Williams, Armstrong Container Corp and DuPont.

Catholdi-Dow knows that the effects of acute lead exposure will become more obvious as he gets older, when school becomes more demanding. Currently, her son is mostly non-verbal unless he’s repeating songs or TV shows that he likes. And while it’s difficult to disentangle the effects of lead poisoning from his autism diagnosis, she and his doctors feel that his hyperactivity may be one consequence of the exposure.Catholdi-Dow knows that the effects of acute lead exposure will become more obvious as he gets older, when school becomes more demanding.

Catholdi-Dow thinks one thing that could prevent lead exposure in future children would be to make lead testing and education a standard part of prenatal care and preparation for a new baby. “And if you’re buying a home, definitely get it checked for lead before purchasing it, especially if it’s a home built before 1978,” she said.Catholdi-Dow thinks one thing that could prevent lead exposure in future children would be to make lead testing and education a standard part of prenatal care and preparation for a new baby. “And if you’re buying a home, definitely get it checked for lead before purchasing it, especially if it’s a home built before 1978,” she said.
