Why Lead Is Dangerous: 5 Health Concerns

Is lead paint harmful to humans?

Lead is a naturally occurring poisonous metal that was used in different industries throughout history.

This widespread usage has led to extensive environmental contamination, human exposure, and significant public health issues in many regions across the globe.

One of the prevalent sources of lead exposure is lead-based paint, which was commonly used in the construction of residential buildings before being banned in 1978.

To reduce the risk of lead exposure, you should conduct a lead paint test to determine if your home or building contains lead-based paint.

What Is Lead, and Where Is It Found? 

Lead is a heavy metal that occurs naturally in the Earth’s crust but has been mined, smelted, and used in various products and materials.

Although the use of lead in many products has been significantly reduced, it can still be found in objects such as car batteries, certain electronics, and even some cosmetics.

The most common source of lead exposure for individuals, particularly children, is lead-based paint and contaminated dust particles. Other sources of lead exposure include contaminated soil, water pipes, and certain consumer products.

Is Lead Paint Harmful to Humans?

Yes, lead exposure through lead-based paint is harmful to humans. When lead paint deteriorates, it releases lead-contaminated dust particles into the air and onto surfaces.

Ingesting or inhaling these particles can have severe health consequences, particularly for young children at a higher risk of exposure due to hand-to-mouth behaviors.

Performing a lead paint test on your home or building can help identify any potential lead-containing materials and take the necessary steps to remove them safely.

How Does Lead Enter Your Body?

You may wonder how lead enters your body. Well, the most common ways are inhalation and ingesting lead-contaminated dust particles. Inhalation occurs when tiny particles, which may be invisible to the naked eye, become airborne and enter the lungs.

Ingestion happens when contaminated surfaces are touched with hands that have not been washed after contact with lead dust or when food is prepared on a contaminated surface. Once inside, lead accumulates in bones, blood, and tissues.

What are the Immediate Health Effects of Lead Exposure?

Acute lead poisoning can cause a wide range of symptoms, including abdominal pain, constipation, fatigue, headache, irritability, loss of appetite, memory loss, pain or tingling in the hands and feet, and weakness.

It can lead to seizures, coma, and even death in severe cases.

What are the Long-Term Health Effects of Lead Exposure?

High levels of lead in the body can cause severe health issues. Here are a few of the most common long-term health effects associated with lead exposure:

#1. Long-term Harm to the Brain and Nervous System

Lead exposure can cause severe long-term damage to the brain and nervous system. Lead can readily cross the blood-brain barrier and accumulate in the brain, interfering with normal neurological function.

It’s exposure has been linked to decreased cognitive function, memory problems, and mood disorders in adults.

In children, the risks are even more pronounced; lead exposure can lead to learning disabilities, reduced IQ, behavioral issues, and even brain damage.

According to the Centers for Disease Control and Prevention (CDC), children have no safe blood lead levels. That makes it imperative for parents to ensure that their home environments are free from lead.

#2. High Blood Pressure and Cardiovascular Problems

Chronic lead exposure is also linked to increased blood pressure and cardiovascular problems. Lead damages the cells lining blood vessels and interferes with the body’s blood pressure regulation.

Over time, this can increase the risk of hypertension, heart disease, and stroke. The American Heart Association warns that even low-level exposure to lead can result in elevated blood pressure levels.

#3. Developmental Delays in Children

Children are highly susceptible to the detrimental impacts of lead exposure. It can lead to a range of health issues, including developmental delays, decreased IQ, and behavioral problems.

According to the World Health Organization (WHO), young children, especially those under 6, are particularly vulnerable to the harmful effects of lead exposure due to their rapid growth and development and their tendency to put objects in their mouths. 

#4. Kidney Damage

The kidneys have a big role in filtering waste and toxins from our bodies, and lead can overwhelm your them. Lead can cause permanent kidney damage over time, resulting in other health consequences.

Kidney damage may be hard to notice, as symptoms are often absent. It can manifest as increased protein in the urine, elevated blood pressure, or a higher risk of gout. If you suspect an issue, consult your healthcare provider for lead testing.

#5. Reproductive Problems

Lead poisoning can affect your reproductive system in men and women. According to the WHO, lead exposure is linked to decreased semen quality and sperm motility which could result in infertility issues.

Researchers have also found that women exposed to higher lead levels are at increased risk of miscarriage, stillbirth, or premature delivery.

What are Common Symptoms of Lead Exposure?

Symptoms of lead poisoning can include:

  • Headaches
  • Constipation
  • Stomach pain
  • Sleep disturbance
  • Irritability
  • Trouble sleeping
  • Memory loss
  • Decreased appetite
  • Always feeling tired
  • Metallic taste in the mouth

Can Lead Exposure Cause Mental Health Issues?

Research has linked lead exposure to various mental health issues, including depression, anxiety, and possibly even schizophrenia.

In children, lead exposure has been associated with attention deficit hyperactivity disorder (ADHD) and conduct disorder.

How Can You Mitigate Lead Exposure? 

The best way to reduce your risk of lead exposure is to test your home for any potential lead-containing materials. If you live in a house built before 1978, you may have lead-based paint on your walls or furniture.

Professional companies can perform lead paint testing and help you determine the safest way to remove hazardous materials if there are any.
