Poison Control Centers Glossary of Terms

The following are health and medical definitions of terms that appear in the Poison Control Centers article.

Breathing: The process of respiration, during which air is inhaled into the lungs through the mouth or nose due to muscle contraction, and then exhaled due to muscle relaxation.

Poison: Any substance that can cause severe distress or death if ingested, breathed in, or absorbed through the skin. Many substances that normally cause no problems, including water and most vitamins, can be poisonous if taken in too large of a quantity. Poison treatment depends on the substance: if there are treatment instructions on the substance's container and you are sure it contained no other item, follow those directions immediately. Always contact your nearest Poison Control Center if you are concerned about possible poison ingestion.

    • Burns (First Aid)
      • Burns are categorized by severity as first, second, or third degree. First degree burns are similar to a painful sunburn. The damage is more severe with second degree burns, leading to blistering and more intense pain. The skin turns white and loses sensation with third degree burns. Burn treatment depends upon the location, total burn area, and intensity of the burn.
    • Mercury Poisoning
      • Mercury is a naturally occurring element found in water, soil, and the air. Mercury is also contained in some fish, some of the products we use in the home, school, or dentist. Information about sources of mercury exposure, potential health effects, symptoms of exposure, fish that may contain mercury, consumer products that contain mercury, and ways to reduce your exposure to mercury is important for the health of you, and your family.
    • Lead Poisoning
      • Lead-based paint and lead contaminated dust are the main sources of exposure for lead in U.S. children. Lead-based paints were banned for use in housing in 1978. All houses built before 1978 are likely to contain some lead-based paint. However, it is the deterioration of this paint that causes a problem. Approximately 24 million housing units have deteriorated leaded paint and elevated levels of lead-contaminated house dust. More than 4 million of these dwellings are homes to one or more young children. Lead poisoning is entirely preventable. The key is stopping children from coming into contact with lead and treating children who have been poisoned by lead.
