LEAD POISONING SYMPTOMS |
||
|
Before scientists knew how harmful it
could be, lead was widely used in paint, gasoline, water pipes, and
many other products. Today house paint is almost lead-free, gasoline
is unleaded, and household plumbing is no longer made with lead
materials. Still, remnants of the old hazards remain. Following are
some sources of lead exposure: Lead-based paint. This is the most common source of exposure to large amounts of lead among preschoolers. Children may eat paint chips from older homes that have fallen into disrepair. They may also chew on painted surfaces such as windowsills. In addition, paint may be disturbed during remodeling. Dust and soil. These can be contaminated with lead from old paint or past emissions of leaded gasoline. In addition, pollution from operating or abandoned industrial sites and smelters can find its way into the soil, resulting in soil contamination. Drinking water. Exposure may come from lead water pipes, found in many homes built before 1930. Even newer copper pipes may have lead solder. Also, some new homes have brass faucets and fittings that can leach lead. Jobs and hobbies. A number of activities can expose participants to lead. These include making pottery or stained glass, refinishing furniture, doing home repairs, and using indoor firing ranges. When adults take part in such activities, they may inadvertently expose children to lead residue that is on their clothing or on scrap materials. Food. Imported food cans often have lead solder. Also, lead is found in leaded crystal glassware and some imported or old ceramic dishes. In addition, food may be contaminated by lead in the water or soil. Folk medicines. Certain folk medicines (for example, alarcon, alkohl, azarcon, bali goli, coral, ghasard, greta, liga, pay-loo-ah, and rueda) and traditional cosmetics (kohl, for example) contain large amounts of lead. Chronic lead poisoning New evidence suggests that lead may be harmful to children even at low levels that were once thought to be safe, and the risk of damage rises as blood levels of lead increase. The symptoms of chronic lead poisoning take time to develop, however. Children can appear healthy despite having high levels of lead in their blood. Over time, though, problems such as the following may arise: Learning disabilities Hyperactivity Mental retardation Slowed growth Hearing loss Headaches. Lead poisoning is also harmful to adults, in whom it can cause high blood pressure, digestive problems, nerve disorders, memory loss, and muscle and joint pain. In addition, it can lead to difficulties during pregnancy, as well as cause reproductive problems in both men and women. Acute lead poisoning Acute lead poisoning, while less common, shows up more quickly and can be fatal. Symptoms such as the following may occur: Severe abdominal pain Diarrhea Nausea and vomiting Weakness of the limbs Seizures Coma. |
