Lead poisoning information and resources for parents

How can lead affect my child?

Very small amounts of lead can have a serious and permanent effect on a child's growth and development. The amount of lead dust that can poison a child is so tiny, you can’t see it on your hands, toys, floors, or other surfaces. Even small amounts of lead in their body can harm your child's ability to think, learn, and focus.  Lead poisoning can cause:

  • Delays in speech, learning, growth and development
  • Hyperactivity and behavior challenges
  • Lower IQ and lower achievement in school
  • Damage to a child’s body, including brain, kidney and nervous system
  • Hearing loss
  • Death
     

Why is it important to test my child for lead?

All children in New Hampshire should have their lead levels tested at age 1 year, and a second test at age two years.  Don’t be fooled -- children who look happy and healthy can have dangerous levels of lead in their bodies. The only way to know if your child has lead in their body is to have them tested. These lead level tests are routinely done during a child's well-child doctor’s appointment, and the cost is covered by insurance. 
 

How are children becoming poisoned?

In the US, most kids are poisoned from lead paint in older homes. This old lead paint makes lead dust that is almost invisible to the naked eye. Lead paint and dust in buildings built before 1978 make up to 70% of children with lead poisoning in the US. Children can also be poisoned by lead in their food, or water, in the soil where they play, from use of cultural products, consumer products, or by adult family members bringing lead home from the workplace

Testing for Lead at one and two is what we do!

Lead in older housing

Even though 52% of the homes in New Hampshire were built before 1978 and may contain lead, lead poisoning is entirely preventable.  Understanding where you can find lead in your home is the first step to keeping your family safe. Lead paint is a hazard when: 

  • It is on windows, door frames, and floors and other areas around the house that are bumped or rubbed. 
  • It is peeling or chipping. 
  • It is on a chewable surface that a child can reach like a windowsill. 
  • It is in the soil in a child’s play area or in the 3-foot area around the outside of the home.
     

Easy steps to reduce lead found in your home   

  • Read the DHHS factsheet on Lead in Your Home
  • Find out what year your home was built. If it was built before 1978 it may contain lead paint.
  • Use disposable wipes or a HEPA vacuum to clean up dust and paint chips.
  • Hire RRP certified contractors trained in lead safe work practices for renovations and repairs. 
  • Learn how to work ‘lead-safe’ before starting do-it-yourself home repair or renovation projects. 
  • Hire a licensed NH lead professional to do a lead inspection risk assessment of your home. 
     

Lead can be in your drinking water  

Though drinking water is not the number one way a child can get lead into their bodies, it is important that a child never drinks water with lead in it.  Lead can get into your drinking water from:

  • Worn out pipes that bring the water into the home from the water line under the road.  
  • Water faucets that are brass and chrome-plated can contain lead. 
  • Water that sits in pipes for more than 6 hours when you are away from home or overnight. 
  • Old claw-foot bathtubs. 
     

 Easy steps to reduce any lead found in your drinking water

  • Before drinking, cooking, or making baby formula, if the water has been sitting in the pipes for more than six hours, run it a minute or until the water feels cold. 
  • Use cold water for drinking, cooking, and making baby formula. 
  • Don’t let your child drink water from the garden hoses. 
  • Clean your faucet’s screen regularly.
  • Use a water filter certified to remove lead and replace the filter regularly. 
  • Call the NH State Water Lab to get a water test.  
  • Talk to your children’s school or childcare facility to see if they have tested their water or check out View Results | NH Department of Environmental Services.
  • Find out if you have lead pipes in your home by using the Protect Your Tap Tool.
  • Read the Drinking Water Factsheet.
Frequently Asked Questions

What is Lead?

Lead can be found in older homes, drinking water, food, and consumer products. If your home was built before 1978, it may contain lead paint. As lead paint ages, it peels, cracks, and chips releasing nearly invisible dust that get into the soil and throughout the home.  This lead dust is very dangerous to young children and pregnant women.  In older homes there may be lead in the drinking water that comes from pipes and faucets that contain lead. Lead dust can be brought into the home or the car from family members that work in jobs with lead.  These jobs include construction, remodeling, painting, battery production and car repairs. Hobbies can also be a source of lead, such as making bullets, fishing sinkers, and stained glass or decorating with antiques. Consumer products such as spices, pottery, antique dishes, make-up, toys and many other items can be the source of lead. To get more information on lead sources go to the Sources of Lead webpage.

What is Childhood Lead Poisoning?

No child should have any lead in their body.  Young children, especially those under six years old, are especially vulnerable to the dangers of lead.  Children can easily ingest lead dust from simply living in an older home. In most cases, this lead dust is nearly invisible and can enter their bodies through their mouth from contaminated hands, snacks, and toys. Lead can also get into their bodies from drinking water, food sources, or consumer products like toys. 

Children under the age of six are at the greatest risk for lead poisoning due to their normal hand-to-mouth activity. These young children explore their world with their hands and mouths, putting them at high risk for lead poisoning. The good news is that lead poisoning is entirely preventable. 

How can lead affect my child?

Beginning in the womb and up until a child is around six years old, the development of a child’s brain lays the foundation for their future growth and learning.  Very small amounts of lead can have a serious and permanent effect on a child's brain and their physical development.  

We now know that even low levels of lead in children can cause:

  • Damage to a child’s body, including brain, kidney and nervous system
  • Delays in speech, learning, growth and development
  • ADHD and other behavior challenges
  • Lower IQ
  • Decreased ability to pay attention
  • Underperformance in school
  • Hearing loss
  • Death

How do I know if my child has lead in his or her blood?

Most children do not look or act sick when they have been exposed to lead. A simple finger stick blood test is the only way to find out if your child has been exposed to lead. Talk to your child’s doctor about having your child tested at one and again at two years old. Children who were not tested at those ages should have a test between 3-6 years of age. A small amount of blood will be taken from the finger, toe or arm and the good news is that this test is covered by insurance.

What do my child’s test results mean?

There is no safe lead level in children. The Centers for Disease Control and Prevention (CDC) and American Academy of Pediatricians (AAP) have set a reference value of 5 micrograms per deciliter (mcg/dL) which means that 97.5% of all children in the U.S. ages 1-5 have blood lead test results below this level. If your child has an elevated blood lead level of 5 mcg/dL or above, this means your child has had more contact with lead than most child of his or her age.

My child had a capillary blood lead done and it was below 3.5 mcg/dL. Do I need to have him or her tested again? 

If your child's blood lead level was 0 -3.4 mcg/dL, no confirmation test is needed until their 1st or 2nd birthday.  If you are undergoing renovations in a home built before 1978, they attend a new child care center built before 1978, someone in the home has a job or hobby that works with lead, or there is a place they spend time at that was built before 1978, mention this to your medical provider. 

My doctor told me my child has an elevated blood lead level. Can I get medicine for this?

Most children who have lead poisoning do not look or act sick and usually do not have symptoms. There is no medical treatment for blood lead levels below 45 mcg/dL. The only treatment is to prevent and decrease exposure to lead through diet, good hygiene and removing the source of lead hazards.

What changes can I make to my child’s diet?

Provide three meals a day and in between meal snacks that are rich in calcium, iron and vitamin C. Good nutrition and hygiene can help reduce the amount of lead a child absorbs in their body. Prevent lead from mixing with food. Give your child healthy snacks. Bake or broil foods, don’t fry. Children with poor diets in calcium, iron and vitamin C are adversely affected by lead.

How can improving hygiene make a difference?

Wash toys, hands and play spaces often. Clean child’s hands, toys, stuffed animals, bottles and pacifiers often. Keep your child’s play area free of dust and dirt. Place a rug at each entry door to stop dirt from tacking into the house. Take shoes off at the door. Wash hands and fingernails after playing outside. Wash yard toys before bringing them inside or just leave the yard toys outside. Wipe pet’s paws off when they come inside.

How do I protect my child from lead?

Remove the lead source and look out for lead hazards. Lead poisoning occurs when children ingest or inhale lead. This means keeping children away from lead paint, the dust that comes from lead based paint breaking down and not taking lead home with you from jobs and hobbies. 

  • Frequently clean with a HEPA vacuum and disposable rags areas where dust and paint chips settle 
  • Wash hands, toys & pacifiers frequently 
  • Keep children away from lead paint & dust 
  • Have your home tested for lead and renovate safely 
  • Test for potential lead contamination in soil or water 
  • Avoid imported foods & candies (i.e. Mexican candies) 
  • Don’t allow children to mouth metal charms, keys, trinkets & jewelry 
  • Don’t use recalled products & toys 
  • Only use cold tap water for drinking and cooking, and mixing formula. 
  • If you have a hobby that involves lead, be sure to change your clothing and wash hands thoroughly before touching your child. 
  • If you work with lead, follows your company’s lead hazard program and practice personal before going into your car and home.

My doctor says my child has been exposed to lead. How often will they check my child to see if the lead is going away?

Most children will be checked in 3 months. Sometimes a doctor will decide to check a child again in 1 month. It is very important that you as the parent keep this follow-up appointment. Lead can take up to 1 year or longer to decrease. That is why repeat blood tests are so important. There is no safe level of lead.

Should other people in my home be tested?

Siblings, playmates and other children who may spend time with you and your family, should be tested if they are younger than 6 years of age. If you are pregnant ask your ob-gyn doctor to test you. If you work with lead or have a hobby with lead components talk to your doctor and ask to be tested.

I am breastfeeding. Should I stop so I can make sure my child is getting enough calcium from other sources?

No, do not stop. Continue to breastfeed. Lead does not concentrate in breast milk because it does not bind to nor dissolve in fat; thus, levels of lead are generally higher in a mother’s blood than in her milk. The benefits of breastfeeding outweigh the negatives. Talk to your doctor and have a lead level done. Some experts believe if the lactating woman has an elevated blood lead level, they need to take twice as much calcium. Please ask your doctor about this.

Could I have given my child lead when I was carrying them?

Only if you worked with lead, were around home renovations or have a hobby that exposed you to lead at the time you were pregnant. If you are pregnant and are exposed to lead, the unborn fetus will be exposed because lead can cross through the placenta. If your child is exploring his or her environment now, the chances are they are being exposed from inside their home.

I have heard children who have been exposed to lead may have developmental problems. Is this true?

Experts have shown some children who have been lead exposed go on to have difficulties in speech, education, show inattention and distractibility, do not grow as fast compared to children who were not lead exposed. If you have concerns about your child’s development, talk to your child’s doctor.

Is it true some child who had elevated blood lead levels may not have any problems until they enter school?

Yes. Pre-kindergarten, kindergarten, first, fourth, sixth and seventh grade are called critical transition points. Children face physical, emotional, social and academic challenges at these times. If you notice inattention, distractibility, aggression, irritability and hyperactivity talk to your child’s doctor and teachers.
