Lead poisoning can result in permanent neurological damage resulting in learning and behavioral problems. The sad thing it is preventable and hard to detect at first. There is over 3 million tons of lead in 60 million American homes.
There are numerous source of lead: in our soil, air, drinking water, and homes. Lead is found on water coolers at school, windowsills, old painted toys and furniture, in the dirt in yards, seals of fine wine, lead crystal glasses, dishes, coffee mugs, crayons, on toys, and even in calcium supplements.
Homes built before 1976 contain some lead in their tap water because of solid lead pipes or lead soldered copper pipes. Lead also can be emitted into the air from motor vehicles and industrial sources, and lead can enter drinking water from plumbing materials.
Lead-based paint may also be a hazard when found on surfaces that get a lot of wear-and-tear. These areas include: windows, sills, doors and doorframes, stairs, railings, banisters, porches and fences. Note: Lead-based paint that is in good condition is usually not a hazard.
Children absorb 50% while parents only 10%. Children pick up lead dust from floors, pets, and toys and then suck their thumbs. The lead compound on paints taste sweet. Lead is stored in baby's teeth and their kneecaps. Lead finds to the red blood cell like iron and is stored like calcium in the teeth. When there is a deficiency of protein, phosphorus, iron, or calcium, more lead is absorbed.
Symptoms of lead poisoning include: irritability, loss of appetite and weight loss, paleness from anemia, learning difficulties, sluggishness, vomiting and constipation, mood disorders, pain and numbness or tingling in the extremities. Adults with lead poisoning have reproductive problems (both men and women), high blood pressure, hypertension, nerve disorders, memory and concentration problems, and muscle and joint pain.
Hobbies like making pottery or stained glass, refinishing furniture, and soldering and melting lead is a great source of lead poisoning. Burning colored newsprint or wood coated with lead paint, results in a release of lead into the air.
Lead gasoline, phased out in 1976, was also a great source. Storage, preparation and serving of foods are another source. Juices from containers that come from lead soldered cans can leak the acids into the juice and be absorbed.
Pigmented designs on pottery dishes and mugs are glazed with lead to make them washable. The glaze contains deadly cadmium. This lead can be absorbed when hot food is served on them. Leaking is increased by acidic food as coffee, pop, fruit juices, or alcohol, combined with the decorative glaze and lead pigment.
In 1990, 90 % of all canned food was packaged in lead soldered cans (98%lead and 2% tin; lead is 10% the cost of tin.). Note that soldered seams are raised and lumpy with gray metal while welded seams are soft, smooth and flat.
Wine formerly had corks sealed with hot wax and lead foil wrapped around it. The lead went into the wine. Place the wine in fine crystal and you also have immediate absorption of lead also from the crystal directly into the wine.
Calcium pills are made from bone meal and oyster shells (sources of lead). Best to choose calcium carbonate or antacids for your source of calcium. _Brass bowls contain 3% lead. Pewter is made from tin and lead. Silver plates contain often an alloy of lead.
Newspapers with colored print contain lead. (So don't wrap your fish in the comics.) Water coolers had lead lined storage tanks until 1988. Sandblasting of old bridges releases a large amount of lead.
Pregnant moms absorb more that non-pregnant woman. The average lead levels were 17 micrograms per cc in 1976 and today are 4 micrograms. In 1965 the levels were 60 and dropped down in 1985 to 30 and by 1990 to 10 micrograms.
NEW STRICT LEAD RULES GO INTO EFFECT
Strict rules for lead in kid’ products go into effect on Feb. 24. The Consumer Product Safety Commission (CPSC) helped librarians, clothing makers, craft sellers and thrift stores get temporary exemptions. Crafts made of natural woods are getting exemptions. Librarians said they might have to ban kids to keep them away from books that are safe. They also delayed lead testing until next year.
The new law states kids’ products must have less than 600 parts per million of lead. The sweeping bill is broad and could drive out some business. The bill had a tight deadline and unfortunately has no new funding. The thought is good, but the execution seems poor.
