What is Lead?
  • Lead is a metal that is poisonous if eaten
  • Solid form usually used as fishing weights

Lead Poisoning
  • Most common disease of toxic environment origin
    in the US
  • Previously believed to be toxic to children only
  • Currently known to be harmful to people of all
    ages at levels that a few years ago were
    considered safe

Adult Exposure
  • Most Adult exposure occurs in the workplace
  • Usual route of occupational exposure is
  • NIOSH estimates more than 3 million workers in US
    at risk

Childhood Exposure
  • Predominantly exposed by ingestion
  • An estimated 3 to 4 million American pre-school
    children have blood levels that are now known to
    be associated with sub clinical neurological
  • Among inner-city preschool children 68 have
    higher levels of lead exposure

  • Smeltering
  • Battery Making
  • Ship Burning
  • Soldering
  • Stained Glass Manufacture
  • Brass Foundry Work
  • Lead Base Paint Abatement
  • Leaded crystal and improperly fired ceramic and
    pottery especially if used to store food or drink

Typical Exposures
  • Contaminated Dust and Soil
  • Suburban and urban areas have lead in dust and
    soil from flaking paint from buildings and
    bridges and smaller amounts from automobile
  • Water can become contaminated as it passes
    through lead pipes or comes into contact with
    lead solder

Industries Associated with Lead Overexposure
  • Battery Manufacturing
  • Chemical Industry
  • Construction Workers
  • Demolition Workers
  • Firing range instructors
  • Foundry Workers
  • Gas station Attendants
  • Gasoline Additives production
  • Jewelers

Industries Associated with Lead Overexposure II
  • Lead Miners
  • Lead smelters and refiners
  • Pigment Manufacturing
  • Pipe Fitters
  • Plastics Industry
  • Pottery Workers
  • Printers
  • Radiator repair

Industries Associated with Lead Overexposure III
  • Rubber industry
  • Soldering of lead products
  • Solid waste production
  • Stained glass makers
  • Welders

Alternate Sources of Lead in the Home
  • Making stained glass windows using lead solder
  • Glazing firing pottery and ceramics
  • Making lead weights
  • Reloading and making ammunition
  • Target practice on indoor and outdoor firing
  • Refinishing furniture
  • Remolding

Home Remedy Exposures
  • Azarcon and greta are bright colored powders that
    contain almost 100 lead-
  • Used in the Hispanic community for children with
    intestinal illness
  • Pay-loo-ah is a red or orange powder used with
    the Hmong community for curing rash and fevers
  • Ghasard, Bala Boli and Kandu are Asian Indian
    remedies used for stomachaches
  • Kohl or surma are used by Arabs for cosmetic and
    medicinal purposes

Additional Routes of Entry
  • Lead may be inhaled when it is burned or melted
    releasing some of the lead as a fume
  • May be inhaled when dust that contains lead
    becomes airborne ex. Contaminated clothing worn
    home or dry lead paint removed from a surface
  • Ingested when cigarettes, food or food
    preparation surfaces contaminated by lead dust

Effects of Lead Poisoning
  • Irreversible negative health effects
  • Hypotension
  • CNS problems
  • Anemia
  • Diminished Hearing
  • Sterility
  • Coma

  • Good Housekeeping/hygiene
  • Cover or repaint surfaces where lead paint is
    chipping or cracking
  • Wash hands frequently
  • Proper nutrition with adequate amounts of iron
    and calcium may help decrease absorbed lead
  • Never sand, burn, or heat a surface that may
    contain lead based paint
  • Run tap water for a minute before consuming

Prevention Continued
  • Use cold tap water to prepare baby formula
  • Do not allow children to play in dirt within 3
    feet of your house foundation
  • Use a doormat to wipe feet or remove shoes to
    keep dust out of the house
  • Remove imported vinyl mini blinds from areas
    frequented by small children
