More than likely, you know about the dangers of lead poisoning. You might even know that lead is dangerous because of how it affects so many various aspects of the human body. But you might not know about National Lead Poisoning Prevention Week (NLPPW) or what lead poisoning has to do with air quality.

The Centers for Disease Control, Environmental Protection Agency and Department of Housing and Urban Development established NLPPW in order to raise awareness and reduce childhood lead exposure. This year, the prevention week is being celebrated Oct. 24-30. The theme is “Get the Facts. Get Your Home Tested. Get Your Child Tested.” According to the World Health Organization, “children absorb 4 to 5 times as much ingested lead as adults from a given source.” This explains the results of a report by UNICEF and Pure Earth that determined 1 in 3 children have lead poisoning. And, it explains why so many children are robbed of their healthy youth due to an entirely preventable cause. 

What Is Lead?

Lead is an element found in the earth’s crust in small quantities. It is a highly durable metal that is toxic to humans and animals. Lead is found in the air, soil and water. When in the air, lead is able to travel long distances before settling. In other words, you never know where you might find lead!

Common Sources of Lead Pollution

In previous years, the automotive sector produced the majority of lead pollution. Leaded gasoline-fueled cars emitted awful exhaust emissions. Today, lead pollution mainly comes from soils, incinerators, lead-acid batteries, recycling, mining, smelting, leaded aviation fuel and various other industrial sources. 

Efforts To Eliminate Lead Pollution 

Over the years, Congress has passed numerous laws administered by the EPA to protect the nation from lead poisoning. As a result of these regulations and various others, lead pollution decreased by 98% between 1980 and 2014. The following is a timeline of notable acts from the 1970s to the 1990s. 

  • Residential Lead-Based Paint Hazard Reduction Act (1992)
  • Comprehensive Environmental Response, Compensation and Liability Act (1980)
  • Toxic Substances Control Act (1976)
  • Resource Conservation and Recovery Act (1976)
  • Safe Drinking Water Act (1974)
  • Clean Water Act (1972)

What Are the Health Effects of Lead Poisoning?

Lead poisoning occurs through inhalation or ingestion. Once lead enters the body, it travels through the bloodstream and accumulates in the bones. Lead adversely affects the nervous system, reproductive system, cardiovascular system and various other bodily functions. It also impacts the bloodstream’s ability to carry oxygen throughout the body. 

Because you can inhale lead particles, lead poisoning is an air quality issue.

Lead Poisoning in Children

Unfortunately, the health effects children experience due to lead poisoning are often irreversible. Children may experience learning and behavioral issues, difficulty speaking and hearing, anemia as well as liver, kidney and brain damage. An already vulnerable population group, children are extremely susceptible to adverse health effects from lead poisoning.

Lead Poisoning in Pregnant Women 

A pregnant woman that is exposed to lead may unintentionally poison the baby when her blood travels through the placenta and enters the baby’s bloodstream. Pregnant women have an increased risk of miscarriage and premature birth. And, the baby may experience developmental effects.        

Lead Poisoning in Adults

Adults with lead poisoning may experience reproductive, digestive and neurological issues. Other effects include muscle and joint pain, renal disease and failure, hypertension and cancer. 

Acute vs. Chronic Lead Poisoning

The symptoms of acute lead poisoning and chronic lead poisoning are not similar, but both must be monitored carefully.

Acute symptoms include:

  • Coma
  • Fatigue
  • Nausea
  • Vomiting
  • Seizures
  • Headache

Chronic symptoms include:

  • Irritability
  • Loss of appetite
  • Poor coordination
  • Shortened attention span 
  • Heart rate variability

Lead Posioning and Air Quality

How does lead pollution impact air quality? Lead saturated air, whether indoors or outdoors, is toxic to the humans and animals that breathe it in. The effect of lead on air quality and human health is comparable to that of particulate matter and ground-level ozone. Lead pollution worsens air pollution and decreases the Air Quality Index rating. Lead pollution spreads with the wind, endangering nearby communities. That is why it’s important to do your part to prevent lead pollution.

Indoors, lead poisoning often occurs due to high concentrations of airborne lead particles. These inhalable toxic contaminants are caused by improper lead paint removal, certain indoor activities and nearby outdoor sources that spread lead dust and contaminated soil. While lead paint is the most common concern, good indoor air quality is necessary to protect against all forms of airborne lead poisoning.

Is Lead Poisoning Preventable?

Lead poisoning is completely preventable! There are several steps that you can take to keep your family safe. 


If your home was built before 1978, perform renovations with caution and awareness. If lead paint is in poor condition, paint over it or hire a professional that specializes in lead paint removal. However, if lead paint is in good condition, leave it alone. Separate remodeling areas from living areas with plastic sheeting. Children and pregnant women should not be present during renovations nor should they have access to areas under construction. 


Have children wash their hands frequently, particularly before they eat and after they play outdoors. Limit any play in the soil. Instead, provide them with a grassy area or sandbox that remains covered when not in use. Wash their toys regularly, particularly after outdoor use. And, have them remove their shoes before they enter the house. 

Other Tips and Tricks 

  • When dusting, use a damp cloth, mop or similar item to clean surfaces. 
  • Remove shoes before entering the house to avoid tracking in soil and pollutants. 
  • Make sure tap water is filtered. 
  • Avoid using imported pottery and dishware to store food. 
  • Review the EPA’s Lead Poisoning Home Checklist

Preventing Lead Pollution 

Lead poisoning is preventable. Practicing good hygiene, monitoring the environments that children and pregnant women are exposed to and understanding the signs of acute and chronic lead poisoning are excellent starting points. However, there is more to be done. There is no known safe blood level lead concentration. You may want to consider attending city council meetings to voice your concerns about local lead regulations. We must double down on policies and procedures to protect ourselves and our families.
