About Lead-Based Paint

Lead is a highly toxic metal that may cause a range of health problems, especially in young children. When lead is absorbed into the body, it can cause damage to the brain and other vital organs, like the kidneys, nerves and blood.

Lead may also cause behavioral problems, learning disabilities, seizures and in extreme cases, death. Some symptoms of lead poisoning may include headaches, stomachaches, nausea, tiredness and irritability. Children who are lead poisoned may show no symptoms.

lead-poisoningmouthrailBoth inside and outside the home, deteriorated lead-paint mixes with household dust and soil and becomes tracked in. Children may become lead poisoned by:

  • Putting their hands or other lead-contaminated objects into their mouths,
  • Eating paint chips found in homes with peeling or flaking lead-based paint, or
  • Playing in lead-contaminated soil

What can you do?

 If your home was built before 1978:

  • Wipe down flat surfaces, like window sills, with a damp paper towel and throw away the paper towel,
  • Mop smooth floors (using a damp mop) weekly to control dust,
  • Take off shoes when entering the house
  • Vacuum carpets and upholstery to remove dust,
  • If possible, use a vacuum with a HEPA filter or a “higher efficiency” collection bag,
  • Pick up loose paint chips carefully with a paper towel and discard in the trash, then wipe the surface clean with a wet paper towel,
  • Take precautions to avoid creating lead dust when remodeling, renovating or maintaining your home,
  • Test for lead hazards by a lead professional. (Have the soil tested too).

For your child:

  • Have your child’s blood lead level tested at age 1 and 2. Children from 3 to 6 years of age should have their blood tested, if they have not been tested before and:
    1. They live in or regularly visit a house built before 1950,
    2. They live in or regularly visit a house built before 1978 with on-going or recent renovations or remodeling
    3. They have a sibling or playmate who has or did have lead poisoning
  • Frequently wash your child’s hands and toys to reduce contact with dust,
  • Use cold tap water for drinking and cooking
  • Avoid using home remedies (such as arzacon, greta, pay-loo-ah, or litargirio) and cosmetics (such as kohl or alkohl) that contain lead
  • Certain candies, such as tamarindo candy jam products from Mexico, may contain high levels of lead in the wrapper or stick. Be cautious when providing imported candies to children
  • Some tableware, particularly folk terra cotta plates and bowls from Latin America, may contain high levels of lead that can leach into food.

What is asbestos

Learning

asbestos_3Asbestos refers to a set of six naturally occurring fibrous minerals. Asbestos has six primary sub-classifications: chrysotile, crocidolite, amosite, anthophyllite, tremolite, and actinolite. Among these, chrysotile and amosite asbestos are the most common.

Although asbestos fibers are microscopic in nature, they are extremely durable and resistant to fire and most chemical reactions and breakdowns. These properties of asbestos were the reasons that supported its use for many years in a number of different commercial and industrial capacities. The strength of asbestos, combined with its resistance to heat, allowed it to become the material of choice in a variety of products, including, but not limited to, roofing shingles, floor tiles, ceiling materials, cement compounds, textile products, and automotive parts. Asbestos is now strictly regulated as exposure to this toxic mineral can now be directly and scientifically linked to a number of lung and respiratory health conditions.

Why is Asbestos Hazardous?

The use of asbestos sharply declined in the late 1970s when it became evident that asbestos posed a threat to human health and safety. Today, asbestos is classified as a known human carcinogen. The property of durability—which made asbestos so desirable to manufacturers—is that which makes asbestos hazardous. Asbestos fibers are microscopic (roughly .02 the diameter of a human hair), and therefore, are easily inhaled. Once inhaled, the fibers cling to the respiratory system, including the lining of the lungs and inner cavity tissue. As asbestos fibers are typically quite rigid, they become lodged in the soft internal tissue of the respiratory system and are not easily expelled or broken-down by the body.

Hundreds of thousands of people were exposed to asbestos in some capacity as a result of the mineral’s extensive use in domestic, commercial, and industrial products. There is no safe type of asbestos and no safe level of exposure. Nearly all those with exposure history are potentially at risk of serious respiratory health complications.

Who is At Risk of Exposure to Asbestos?

There were hundreds of occupations affected by asbestos exposure. Asbestos was used in thousands of commercial products and industrial capacities and those working with the material in these industries are potentially at risk of harmful exposure. Industries in which asbestos use was particularly prevalent include shipbuilding, commercial product manufacturing, power plants, and construction. Workers employed in these industries prior to 1980 likely encountered asbestos products.

While asbestos exposure is hazardous, not all asbestos products are inherently hazardous. Because asbestos must be inhaled to represent a health risk, only loose asbestos fibers or those in the air supply (a condition known as friable) represent a true hazard. Stable asbestos compounds, such as intact cement, tiles, or other products are generally not an immediate hazard.

Exposure to friable asbestos fibers was common when grinding, chipping, demolishing, or retrofitting asbestos products. Each of these functions could potentially release asbestos into the air supply where it would be easily inhaled.

What Health Conditions are Associated with Exposure to Asbestos

There are three major lung conditions traced directly to asbestos exposure. These are lung cancer, mesothelioma, and asbestosis. Lung cancer risk, typically associated with tobacco use, is known to be exacerbated by exposure to asbestos. Symptoms include coughing, chest pain, and difficulty breathing.

Mesothelioma is a rare and aggressive cancer of the lung and inner body’s cavity lining- a thin membrane known as the mesothelium. Mesothelioma is typically recognized as the most clearly attributable disease resulting from asbestos exposure. Mesothelioma originates in three locations. Pleural mesothelioma forms in the lining of the lungs and is the most common form of the disease. Peritoneal and pericardial mesothelioma are less common and form in the lining of the abdominal cavity and lining of the heart, respectively.

Asbestosis is a degenerative and progressive non-malignant long-term respiratory condition. Asbestosis results from the formation of scar tissue plaques on the visceral surface of the pleura. Asbestosis can represent a pre-cursor to the onset of mesothelioma.
