Lead is a naturally occurring metal found in the earth's crust. Lead has been mined, processed, and used in commercial and household products for hundreds of years. In the past, lead was used in paint, gasoline, pottery, water pipes and other products.
Why Is it Dangerous?
Unfortunately, lead is a poison and harms people if it enters the body. Once lead enters the human environment, there is no way to destroy it or make it harmless. Therefore, we must control exposure to lead.
Lead poisoning occurs when too much lead builds up in the body. Children and adults can get lead poisoning by breathing or swallowing dust that contains lead. Once absorbed, it affects almost every organ and system in the body. Even a little lead can make children slower learners. Very high levels of lead exposure can cause coma, seizures and death.
Exposure to lead can cause:
- Brain damage and lower intelligence
- Behavior and learning problems
- Impaired speech and language
- Slowed growth
- Kidney and liver damage
Signs of lead poisoning are not always easy to see. Children can be poisoned by lead, but not look or act sick. Many children who have lead poisoning look and act healthy. Because of this, lead poisoning may go unrecognized. A blood lead test is the only way to find out if a child has lead poisoning.
Where Is Lead Found?
Children are poisoned by lead when they breathe lead dust or eat items that have lead in them or lead dust on them. Lead can be found in a variety of sources around the home. Below are the most common:
Lead dust is the main cause of lead poisoning in children. Lead dust is created where surfaces containing lead, such as windows, doors, steps and porches painted with lead paint, rub together. Lead dust can gather on floors, in carpets, on toys and other objects that children may put into their mouths. Remodeling or repainting can also increase the amount of lead dust in your home.
Chipping, peeling or chalking lead paint is a common source of lead dust and may be a hazard. Lead-based paint may also be found on toys, furniture and playground equipment.
The older the home, the more likely it is that lead paint was used. This is especially true for homes built prior to 1950, but lead-based paints were widely used up to the time they were banned for residential purposes in 1978. Lead paint in good condition is usually not a problem, except in places where painted surfaces rub against each other and create dust, such as where windows open and close.
Soil and dirt around homes and apartment buildings may contain lead from lead-based paint or from car exhaust fumes. Children may come into contact with lead by playing in bare dirt. Lead in soil can cause contaminated dust to settle on garden plants in summer months. Rinse vegetables well and plant gardens away from old painted structures.
Pottery & Jewelry
Imported, old, handmade or poorly glazed ceramic dishes and pottery may have lead in the glaze. Lead may also be found in leaded crystal, pewter and brass dishware.
Acidic foods or drinks (such as orange, tomato and other fruit juices, tomato sauces, wines, and vinegar) stored in improperly glazed containers are the most dangerous because they may leach lead at a higher rate than other foodstuffs. There are also some types of jewelry that contains high amounts of lead. More about lead in Mexican pottery»
Workplaces and Hobbies
Welding, auto or boat repair, the making of ceramics, stained glass, bullets, and fishing weights are examples of hobbies that may use lead. Other hobbies that could potentially lead to lead exposure include furniture refinishing, home remodeling, painting and target shooting at firing ranges.
Water Pipes and Solder
Lead in drinking water is not a common source of lead poisoning in Oregon. Most well or city water does not naturally contain lead. Lead may get into drinking water from household plumbing, for example, the solder that connects the pipes or brass faucets sometimes contains lead. Lead from solder is most commonly found in homes built between 1970 and 1985. Lead may also get into the water if the water sits in pipes too long. More about lead in plumbing»
In recent years, laboratory testing done in California has found lead in candy imported from Mexico, the wrappers and the clay pots that the candy comes in.
Home Remedies & Cosmetics
Many home remedies may contain lead, including Azarcon, a bright orange powder, and Greta, a yellow powder. Others include:
- Maria Luisa
- Ghasard Bali Goli
Certain cosmetics, especially those from the Middle East, India, and Asia (Kohl, Surma, and Ceruse) may also contain high levels of lead. More about lead kohl and Hindu powders»
