Lead Astray (Parents)
Parents, Jeannette Moninger
It's not just old paint that's poisonous — this toxic metal can
be in water and soil, as well as in a scary number of children's products.
The Lowdown on Lead
When 4-year-old Riley Jackson started having behavior
problems in preschool, his teacher suggested he get checked for lead poisoning.
His mother, Maija, was stunned when the blood test showed that Riley's lead
level was indeed very high — and she frantically tried to pinpoint the cause.
The Jacksons' Baltimore home, built in 1980, showed no
traces of the poison, and Riley's older brother was lead-free too. But Riley
loved to put jewelry and small toys in his mouth — and his parents finally
discovered that there was lead in one of his favorite beaded chain necklaces.
Lead is one of the biggest environmental hazards for kids. More than 310,000
American children ages 6 and under have been diagnosed with lead poisoning,
which can cause lasting learning and behavior problems. And as the Jacksons learned, your
child could be at risk even if there's no lead paint in your home. In the past
few years, the Consumer Product Safety Commission (CPSC) has increased its
testing of kids' jewelry, toys, and even products like sidewalk chalk — and
recalls have skyrocketed. The dangerous products were almost all manufactured
in China and India, where
safety oversight is lax. This year alone, the CPSC has issued 27 different
lead-related recalls for kids' products, including 1.5 million Thomas &
Friends Wooden Railway toys in June, and 17 jewelry recalls. Leaded jewelry is
particularly dangerous because kids tend to put it in their mouth. In fact, a
4-year-old boy in Minnesota
died of lead poisoning last year after swallowing a charm, which Reebok gave
away with some of its sneakers.
Most children with lead poisoning get sick from ingesting
paint dust that lingers in homes built before 1978 — the year that lead was
banned from household paint. The American
Academy of Pediatrics
(AAP) estimates that one out of four homes with young children still has lead.
Blaine Baker, of St. Louis,
was diagnosed by a routine blood test at his 1-year checkup. His parents had
recently renovated their 100-year-old home and, in the course of sanding and
scraping away old paint from the original windows and doors, had unwittingly
released minuscule lead-paint particles into the air. Every time they opened a
window, the friction caused more lead dust to fall, and whenever Blaine crawled or played
nearby, his hands and toys became coated with the nearly invisible poison.
Lead can invade a young child's body surprisingly quickly. Once ingested, it
seeps into the bloodstream, damages the central nervous system, and disrupts
brain circuits that are critical for learning. "Kids exposed to lead tend
to have lower intelligence, learning disabilities, hearing problems, and
behavioral issues like aggression," says Marcel Casavant, MD, chief of
pharmacology and toxicology at Columbus Children's Hospital, in Ohio. Lead can also harm
the heart, liver, and kidneys. "A child with lead poisoning might have
headaches or stomach pains, or become easily tired," says Dr. Casavant.
Since the symptoms of exposure aren't obvious, parents and doctors often assume
they're caused by something else. Even more commonly, though, a child won't
have any symptoms at all.
Babies and toddlers are the most vulnerable because their brains are still
developing and they absorb up to 50 percent of ingested lead (adults absorb
only about 10 percent). Of course, they also spend lots of time crawling on the
floor and putting their hands in their mouth, and because lead tastes sweet,
leaded items can be irresistible.
Even unborn babies are at risk. A pregnant woman who has lead in her system
is at increased risk of miscarriage, stillbirth, and preterm labor. But unless
the exposure was recent, blood tests won't detect the toxin because lead
eventually leaves the bloodstream and settles in bones. "If a woman with
prior lead exposure doesn't get enough calcium in her diet, her body will pull
the mineral from her bones to help her baby grow — but lead comes with the
calcium," says Michael Shannon, MD, chair of the AAP Committee on
Environmental Health. Ask your obstetrician to give you the Centers for Disease
Control and Prevention (CDC) lead risk-assessment questionnaire; if you're
found to be at high risk, eating a diet high in calcium can help protect you
and your baby.
Lead in Surprising Places
But the toxic metal isn't found only indoors: Lead dust and chips from a
home's painted exterior can leach into the ground. "Kids get it on their
hands and toys while playing in the dirt, and family members track it inside on
their shoes," says Dr. Casavant. Drinking water can be contaminated by
lead pipes and solder in old homes and city water systems.
Lead in children's products, however, is a rapidly growing problem; nearly
every week, the CPSC recalls a toy or necklace. Cheap jewelry, particularly
items made in China or India with dull
metallic components, fake painted pearls, and plastic cords, poses the most
risk. According to the CPSC, jewelry sold in recent years by Claire's, Disney,
and American Girl stores, to name just a few, has also tested high for lead.
Over the years, researchers have discovered that lead can be harmful at
lower levels than they'd realized. In fact, the CDC has lowered the
"acceptable blood-lead level" four times. In 1970, a child would have
been diagnosed with lead poisoning if the amount in his blood was 60 micrograms
per deciliter (mcg/dL), but now a child gets the diagnosis if his level is 10
mcg/dL or higher. However, studies have found that IQ levels drop significantly
even when blood-lead levels are lower than 10 mcg/dL. "The more we learn about
lead's effects, the clearer it becomes that there's no such thing as a safe
amount," says Omer G. Berger, MD, director of the Lead Clinic at
Cincinnati Children's Hospital
Now 7, Riley Jackson has a blood-lead level of 6 mcg/dL, down from a high of
28 mcg/dL. However, Riley has been diagnosed with ADHD, and his exposure to
lead could be partly to blame. Research has found that children with levels
higher than 2 mcg/dL are four times more likely to have ADHD, and experts
believe that lead interferes with the body's production of the
neurotransmitters in the brain that are essential for impulse control.
"Kids who are already genetically predisposed to ADHD are at the greatest
risk," says Parents advisor Judith Owens, MD, director of the Learning,
Attention, and Behavior Clinic at Rhode Island
Hospital, in Providence. "Lead probably acts as a
trigger in these children."
Keeping Your Family Safe
It's crucial to reduce a child's lead level in order to prevent further
neurological damage, but sadly, there's no good treatment for the damage that
has already been done. Eating a low-fat diet that's high in vitamin C, calcium,
and iron can slow lead absorption and possibly reduce the effects of exposure.
If a child's blood-lead level exceeds 45 mcg/dL, he'll need a drug that strips
lead from the body (a process known as chelation). "Without treatment,
kids with lead levels of 100 mcg/dL or higher have a serious risk of seizure,
coma, anemia, high blood pressure, organ failure, and even death," says
Dr. Casavant. However, intelligence and behavior problems don't improve
dramatically after chelation, and the drug's side effects can range from
annoying (nausea and sulfur-smelling gas) to life-threatening (decreased
white-blood-cell counts and severe allergic reactions).
The most effective way to lower your child's blood-lead level is to get rid
of the contaminated paint or products in your home. It's not easy to remove
lead paint; using dry sanders and scrapers creates lead dust and fumes, so you
need to use wet-sanding methods along with high-efficiency particulate air
(HEPA) filters. "Since you can make the problem even worse, it's important
to know how to remove lead paint safely," says Ruth Ann Norton, executive
director of the Coalition to End Childhood Lead Poisoning. "Be sure to use
a certified contractor or attend a lead-safety training course in your
If you live in an old home that has lead paint hidden under coats of
unleaded paint, experts say you should leave it alone unless it's blistering,
cracking, or can be easily dislodged. But covered lead paint can still break
down and create toxic dust because of age, friction, or repairs. "Parents
should inspect surfaces regularly for signs of deterioration and clean them
well every week," says Norton. To remove any lingering particles after
renovating, you must use a vacuum with a HEPA filter and wet-clean all
horizontal surfaces (including mini blinds) often. Six months after the Bakers
started using these proper cleaning techniques, Blaine's blood-lead level dropped
With all the recent reports about dangerous chemicals in products made in China,
protecting your kids from lead in metal jewelry and other items is crucial. To
be safe, it's best to check recent product recalls frequently and avoid buying
any cheap jewelry. "Parents assume that products marketed to kids have
been tested for harmful materials like lead," says Norton.
"Unfortunately, that's not always the case." According to the CPSC,
its field investigators purchase a variety of kids' products and test them for
lead — but they can't test every item on the market. Manufacturers are also
responsible for making sure their products don't have high levels.
However, pressure is mounting to improve the system. The CPSC is considering
a stricter policy, which would ban (rather than simply recall) all metal
jewelry and toys containing more than the allowed amount of lead (.06 percent
by weight), and, the Environmental Protection Agency (EPA) recently sent
letters to 120 importing and manufacturing companies with past lead-related
recalls warning them to test their products for lead. Last year, California passed a law
requiring retailers to meet the federal standards for lead content in jewelry;
companies that break the law will pay a fine. "Retailers have until March
2008 to notify metal suppliers, manufacturers, and distributors about the new
standards, and to ensure that products are legal," says Caroline Cox,
research director for the Center for Environmental Health, a nonprofit
organization in California.
Although the law is binding only in that state, companies will probably sell
the lead-safe jewelry nationwide.
To help address the problem of lead contamination during renovations, the
EPA is considering regulations that would require all contractors who work in
child-occupied facilities to be trained in proper lead-paint-removal
techniques. Although in 2000 the President's Task Force on Environmental Health
Risks and Safety Risks to Children established a goal to remove lead paint from
more than 20 million homes by 2010, so far, fewer than half a million of these
homes are lead-safe. "We're still working backward," says Dr.
Shannon. "We identify a lead-poisoned kid, and then we clean up his home.
These homes should be made safe before we allow children to live in them."
Blaine Baker's mother, Cristina, certainly agrees, and she's on a crusade to
prevent other kids from getting sick the way Blaine did. "There are a lot of couples
in our neighborhood who are renovating houses and starting families, and they
don't know that their dream home could cause a nightmare," she says.
"We've got to educate parents and protect children."
