Lead is relatively easily corroded where acetic acid fumes are present and under such conditions it either should not be used or should be efficiently protected. Generally, any contact between lead and organic material containing or developing acids will cause corrosion for instance, unseasoned wood may be detrimental. Trouble from this cause may be prevented by using well-seasoned timber, by maintaining dry conditions, or by separating the lead from the timber by bitumen felt or paint. Lead is also subject to attack by lime and particularly by Portland cement, mortar and concrete, but can be protected by a heavy coat of bitumen. A lead damp-proof course laid without protection in the mortar joint of a brick wall may become severely corroded, especially where the brickwork is in an exposed condition and is excessively damp. 

The most important way families can lower exposures to lead is to know about the sources of lead in their homes and avoid exposure to these sources. Some homes or day-care facilities may have more lead in them than others. Families who live in or visit these places may be exposed to higher amounts of lead. These include homes built before 1978 that may have been painted with paint that contains lead (lead-based paint). If you are buying a home that was built before 1978, you may want to know if it contains lead based paint. Federal government regulations require a person selling a home to tell the real estate agent or person buying the home of any known lead-... 

Some types of paints and pigments that are used as facial make-up or hair coloring contain lead. Cosmetics that contain lead include surma and kohl, which are popular in certain Asian countries. Read the labels on hair coloring products, and keep hair dyes that contain lead acetate away from children. Do not allow children to touch hair that has been colored with lead-containing dyes or any surfaces that have come into contact with these dyes because lead compounds can rub off onto their hands and be transferred to their mouths. 

Acute-Duration Exposure. There are few data available for acute exposures in humans. This may be a function of the time required for the expression of effects (decreased heme synthesis, neurobehavioral changes, increased blood pressure, and interference with vitamin D metabolism) and the usual modes of exposure in humans, which are repeated ingestion of lead-containing dirt or lead-based paint chips in...

In the past, tetraethyl lead was added to gasoline to slow its burning rate in order to prevent engine knock and increase performance. This caused serious and harmful pollution, and lead has since been eliminated as a gasoline additive in most countries. Most exterior (and some interior) house paints once contained high levels of lead as well. Today, the amount of lead in paint is controlled, with not more than 0.05% allowed in the paint material. 

LEADX was developed and is manufactured by Proactive Environmental Research and Development, Inc. (PERDI). PERDI indicates that patents are pending in the United States for processing and treatment of CRT such as those used for displays in televisions and computer monitors. Patents are also pending in the United States for the use of LEADX as an abrasive additive for sandblasting to immobilize lead from lead paint residue. LEADX is distributed by Proactive Applied Solutions Corporation (PASCO). EnviroBest Corporation markets two paint removers containing LEADX called PR-40/LEADX and PR-40AF/LEADX . 

Ancient eye paints often contained cupric oxide, lead sulfide, and lampblack. Their most costly constituent, however, was the stibnite, which had to be imported from distant countries (85). The Hebrew word for this eye paint was puk (85). 

The terminology of the elements suffuses our language, sometimes divorced from the questions of composition to which it once referred. Plumbing today is more likely to be made from plastic pipes than from the Romans (lead) the lead in pencils is no such thing. Cadmium Red paints often contain no cadmium at all. Tin cans have no more than the thinnest veneer of metallic tin it is too valuable for more. The American nickel contains relatively little of that metal. And when was the last time that a Frenchman s pocketful of jingling argent made of real silver ...
