In chemistry, a ketone /ˈkiːtoʊn/ is a functional group with the structure R2C=O, where R can be a variety of carbon-containing substituents. Ketones contain a carbonyl group (a carbon-oxygen double bond). The simplest ketone is acetone (R = R’ = methyl), with the formula CH3C(O)CH3.

The IUPAC name for CH3COCH2CH3 is Butane-2-one.

Some studies have found lead can be absorbed through skin. If you handle lead and then touch your eyes, nose, or mouth, you could be exposed. Lead dust can also get on your clothes and your hair.

There is no way of reversing damage done by lead poisoning, which is why pediatricians emphasize prevention. But a diet high in calcium, iron and vitamin C can help the body absorb less lead.

Lead poisoning usually happens due to prolonged exposure at home, work or daycare. Lead poisoning usually takes months or years of exposure to a small amount of lead at home, work or daycare. When exposed to large amounts of lead, it can quickly lead to lead poisoning (acute poisoning).

Acute Poisoning signs and symptoms

• Pain.
• Muscle weakness.
• Paraesthesia (sensation of “pins” and “needles”)
• Abdominal pain.
• Nausea.
• Vomiting.
• Diarrhea,
• Constipation.

As the body naturally gets rid of the lead, the level of lead in the blood falls. Kids with severe cases and extremely high lead levels in their blood will be hospitalized to get a medicine called a chelator. The chelator attaches to the lead and makes the lead weaker so the body can get rid of it naturally.

Lead paint is very dangerous when it is being stripped or sanded. These actions release fine lead dust into the air. Infants and children living in pre-1960’s housing (when paint often contained lead) have the highest risk of lead poisoning. Small children often swallow paint chips or dust from lead-based paint.

Walls can also be tested for surface lead using a paint testing kit available at your local hardware store. For the test, you rub a solution on the wall. If the solution turns pink, you have lead.

The most common source of lead air pollution indoors is old paint found in homes built before 1978. If left untouched and in good condition, lead-based paint may not pose a significant hazard to health. However, if it is chipped or deteriorating, paint can create dust, chips and suspended particles that can be inhaled.

Removing paint can be dangerous. Many workers continue to develop lead poisoning, however – not from paint peeling off the walls in their apartments, but from dust and fumes they encounter while removing paint.

Scraping can release a lot of dust into the air. Wear safety glasses and consider wearing a dust mask, or even a respirator. A dust mask is completely inadequate when working with lead-based paint. It is also a good idea to wear protective clothing like long-sleeved shirts and painters’ pants.

Yes, you can paint over lead-based paint, but not with just any type of paint. Painting over lead-based paint, also known as encapsulation, is an effective lead paint remediation technique.

On the Job

1. Use a spray bottle to dampen the surface before you begin scraping.
2. Use a wire brush or paint scraper to scrape loose, peeling or chipping paint.
3. Place the scraped materials in a garbage bag and seal.
4. Mist the surface again and lightly sand the edges of the scraped area to remove all loose paint.

We don’t recommend using heat guns or open-flame torches because the lead in the paint can vaporize into the air and be inhaled. The best solution is to prevent paint deterioration in the first place.

(To be completely safe, you may want to consider treating any lead paint–covered surfaces, if you have children living in your home or visiting frequently.) Lead-based paint is most dangerous when it is deteriorating—peeling, chipping, chalking, cracking, etc.
