Activity 1:  
Can you name a source of lead?

 

What is lead poisoning?

Lead is a highly toxic substance, exposure to which can produce a wide range of adverse health effects. Both adults and children can suffer from the effects of lead poisoning, but childhood lead poisoning is much more frequent.

Where is lead found?

Lead Dust from peeling paint, burning painted wood, and home renovations

Lead-Based Paint from older homes, older furniture, and painted toys

Lead-based paint is a hazard if it is peeling, chipping, chalking, or cracking. The older your home is, the more likely it is to contain lead-based paint.

Lead in drinking water from lead pipes and solder in home plumbing.

Other lead sources. Lead can leach into food or beverages stored in imported ceramics or pottery and leaded crystal and china.
Certain hobbies use products with lead in them (fishing sinkers, stained glass, ceramics). Lead can be found in some folk remedies, "health foods" and cosmetics.

Lead in Candy:

The Food and Drug Administration (FDA) is aware of a problem associated with lead contamination of some Mexican candy products being sold in the United States or brought in from Mexico.  Parents should not allow children to eat these products.

FDA has compiled information which indicates that candies and related products that contain significant amounts of chili powder may contain higher lead levels than other types of candy, such as candy that contains predominantly sugar. Examples of chili containing products include lollipops coated with chili and powdery mixtures of salt, lemon flavor and chili seasoning sold as a snack item.

In addition, tamarind, a popular Mexican candy item, can become contaminated with lead if it is sold in poorly made glazed ceramic vessels that release lead from the glaze into the candy.

The FDA is taking action to reduce the risk of potential exposure of children to lead from these candy products. FDA believes that contamination of chili powder may be occurring at certain steps in the manufacturing process.

Lead in Traditional Remedies:

Some medicines from Mexico were found it have lead in them.  Foreign cold medicines: Azarcon 93.5%, lead level (also Rueda, Coral, Alarcon, Liga, Maria Luisa) and Greta (yellow powder) used to treat Empacho (vomiting and colic) has a 97% lead level.

What are the health effects?

Young children:  There are many different health effects associated with elevated blood lead levels. Young children under the age of six are especially vulnerable to lead's harmful health effects, because their brains and central nervous system are still being formed. For them, even very low levels of exposure can result in:
reduced IQ
learning disabilities
attention deficit disorders
behavioral problems,
stunted growth
impaired hearing
kidney damage.

At high levels of exposure, a child may become mentally retarded, fall into a coma, and even die from lead poisoning.

 

Adults:  In adults, lead can:
increase blood pressure and cause fertility problems
nerve disorders, muscle and joint pain, irritability
memory or concentration problems.

It takes a significantly greater level of exposure of lead for adults than it does for kids to sustain adverse health effects.

When a pregnant woman has an elevated blood lead level, that lead can easily be transferred to the fetus, as lead crosses the placenta.

Common symptoms of lead poisoning in children:

Common symptoms of lead poisoning in adults:

Decreased appetite

Stomach ache

Sleeplessness

Learning problems

Constipation

Vomiting

Diarrhea

Tiredness

Lowered I.Q.

Anemia

Fatigue
Depression
Heart failure
Abdominal pain
Gout
Kidney failure
High blood pressure
Wrist or food weakness
Reproductive problems
Anemia

Symptoms are not usually obvious.  The only way to determine if your child has been exposed to lead is by having your child tested.

 

Activity 2:

1. Which of the following is a source of lead?
 a. Lead Dust
 b. Lead-Based paint
 c. Leaded crystal
 d. All of the above

 

2.  Which of the following groups is more vulnerable to lead poisoning?
a. Children
b. Adults
c. Pregnant Women

What are some simple steps to prevent of reduce exposure to lead?

Check your ceramic ware. Some pottery may contain lead that can leach into food and drinks. Avoid eating off any colorfully painted ceramic plates, and avoid drinking from any ceramic mugs unless you know they do not leach lead. This is particularly important if the pottery was made in Mexico or another Latin America country. Generally, pottery made in the US, in Canada, or in Western Europe tends to be safe.

More tips...

Wash your child's hands frequently.

Use cold water for drinking, cooking or making baby formula.  Let it run for 2 minutes before using to reduce lead from pipes.

Stop your child from eating paint chips, and placing hands or toys in their mouth.

Wet mop daily using a powered dishwashing detergent.

Cover cracking or flaking surfaces with a cloth or contact paper until the paint can be removed from a professional permanently.  Don't remove lead paint yourself!

Get your child tested for lead poisoning.  It's the only way to know.

Store foods in plastic or glass containers, not opened metal cans.

Eat well-balanced meals that are high in iron and calcium and low in fat!
