How much lead does it take to poison a child?

But there is surprisingly little agreement on exactly when a child has accumulated a toxic amount of lead. Everybody agrees that there is no "safe" level of lead exposure. However, the CDC doesn't recommend taking action unless a child's blood-lead level exceeds 10 micrograms/dL -- a threshold set in 1991.

What if a child eats pencil lead?

Graphite is relatively nonpoisonous. There may be no symptoms. If symptoms do occur, they may include stomachache and vomiting, which could be from a bowel obstruction (blockage). The person may choke while swallowing the pencil.

How do you get graphite poisoning?

What happens if you inhale pencil lead?

This can cause symptoms such as repeated coughing, chest pain, shortness of breath, or rapid breathing. Sometimes, children will place a piece of a pencil in their nose. This can cause symptoms such as nose pain and drainage, and breathing problems. Infants may become irritable.

How can I test myself for lead poisoning?

A simple blood test can detect lead poisoning. A small blood sample is taken from a finger prick or from a vein. Lead levels in the blood are measured in micrograms per deciliter (mcg/dL).

Can you absorb lead through skin?

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. If this happens, it's possible that you may track home some of the lead dust, which may also expose your family.

What if I accidentally sanded lead paint?

Any sanding, scraping, chipping, or other forms of friction against a lead paint surface can release particles of lead dust into the air, which can be hazardous to human health. Instead, simply wipe down the existing surface with a warm, wet towel to prepare it to be painted over.

Does pencil lead show up on xray?

Unlike metal or glass, a pencil lead is visualized by only 50% of radiographic studies. The pencil lead was invisible in this patient's initial radiograph, but appeared in later studies taken at our hospital. This may reflect different radiation doses in taking X-rays.

Does pencil lead dissolve in water?

It's simply graphite that is soluble in water. Sure, regular graphite can be spread with water a small bit, but this medium is different. When water-soluble graphite is mixed with water, it becomes almost like ink wash. It can be spread over a surface, much like watercolor paint.

How much graphite is in a pencil?

The main components in the manufacture of rods – purified graphite powder and the clay binder kaolin – remain the same; the hardness of the graphite core depends on the ratio of graphite to kaolin, with softer cores containing more graphite. The hardest pencil contains about 20% graphite, the softest one up to 90%.

What is a normal lead level for a 2 year old?

The average lead test result for young children is about 1.4 micrograms per deciliter (µg/dL). 5-14 • Your child's lead level is high. A result of 5 µg/dL or higher requires action. Your doctor or nurse will talk with you about your child's diet, growth and development, and possible sources of lead.
