Lead Poisoning

Lead is a toxic metal that has been used in many products over time. Even in small amounts, lead can have harmful effects on the body, which may lead to lifelong learning, behavioral, reproductive, cardiovascular, and other health problems. While many leaded products have been phased out, lead may still be found in and around older homes and buildings, in certain occupations and hobbies, and some consumer products, remedies, and foods. Lead poisoning is one of the most common environmental illnesses in California, but is completely preventable.

Sources of Lead:

  • Paint
  • Drinking Water
  • Foods, Cosmetics and Medicines
  • Soil
  • Consumer Products
  • Jobs, Hobbies, or Activities

Childhood Lead Poisoning Prevention

Protecting children from exposure to lead is important to lifelong good health. The most important step that parents and caregivers, healthcare providers, and public health professionals can take is to prevent lead exposure before it occurs

The Marin County Childhood Lead Poisoning Prevention Program works towards eliminating childhood lead poisoning and promoting lead-safe work practices.  Lead-based paint is of a particular concern in Marin County, where more than 74% of the housing was built before 1978.  The older the home, the more likely that there are high levels of lead in the paint. Chipping paint, flaking paint, or paint that is being scraped, sanded, or disturbed during remodeling or repairing can create lead dust.

Take Steps to Prevent Lead Exposure:


If you have a child patient with a venous blood lead level result of ≥4.5 mcg/dL, please contact us directly with patient information.
