Refinishing A Bathtub Stops Lead Poisoning
New Source of Lead Poisoning Identified
Reprint from June 95 issue of Refinisher's News
Each day, children bathe in it, play in it, and are washed carefully in it. Yet, according to a special report on the April 19, 1995 edition of Good Morning America, porcelain bathtubs are one of America's most unexpected sources of lead exposure for children, Lead poisoning is currently considered the number one environmental health danger for children by the Centers for Disease Control.
The
nationally televised report cited a study of over 600 tubs conducted by Unique Refinishers of
Atlanta GA. The study found that approximately 64 percent of the tubs tested had
leach able lead on the surface. The tested tubs were of varying age and came from a wide range of domestic and import companies.
Good morning America's report focused on the Thomas family from a small town in Massachusetts. In spite of their efforts to identify and eliminate lead exposure in their home, their two children continued to have very high blood lead levels, requiring continuing medical treatments. the older child had a blood lead level of 47 micrograms per deciliter, while the second child (age 7 months) showed a level greater than 20 micrograms per deciliter.
Aside from negligible lead in the household dust, the only source of lead that could be identified in the
children's environment at the time was the lead-based paint in their home. Even though it was not peeling, they spent $15,000 to have it professionally removed. Away from home during the abatement process (2 months) , the children's blood lead levels decreased to nearly normal levels (1 to 9 micrograms per deciliter). Within a week after moving back into the now lead-free and lead safe home, both children again showed significant elevated blood lead levels.
The family then purchased a home lead test kit called
Lead Check Swabs to test their ceramic ware. When her dishes tested negative for lead, Mrs. Thomas then used a
Lead Check Swab on the bathtub-the only remaining item in the house not yet tested for lead. The swab immediately turned pink, indicating the tub was leaching dangerous levels of lead. Every time the children bathed in the tub and played with their toys, they ingested lead simply by touching the tub and putting
their wet fingers and toys in their mouths, The children ceased using the tub for their baths, and within a few months
their blood lead levels returned to nearly 10 micrograms per deciliter.
We she first tested the bathtub, Patricia Thomas immediately called the
Lead Check Information Hotline to ask questions. The company was surprised by this potential lead source, and sent its top R&D specialist to investigate. Numerous follow-up tests confirmed the initial finding - the bathtub was the problem.
Continued testing of this and other bathtubs has confirmed the
presence of leach able lead in porcelain bathroom fixtures. A baby wipe rubbed on the bottom of a bathtub picked up over 1000 micrograms of lead. Hands rubbed along the side of a
Lead Check
positive tub were shown to pick up significant amounts of lead. Bath water allowed to sit in
Lead Check
positive tubs leached lead in amounts exceeding 50 parts per billion. Washcloths soaked in bath water and rubbed on the bottom of the tub concentrated significant amounts of lead.
Unique Refinishers has now surveyed more than 750 bathtubs and found that, overall 62% of all porcelain tubs tested
positive with Lead Check Swabs. Specifically, 77% of the cast iron tubs, and 25% of the steel tubs tested
positive. This source of lead most likely represents a significant exposure to only very young children with their high level of hand to mouth activity and propensity to "drink" the water during bath time.
The Environmental Protection Agency estimates that more than 57 million U.S. homes have dangerously high lead levels. While bathtubs are a newly identified source of lead, other sources include deteriorating lead paint, water, plumbing, dust and ceramics, to name a few. Refinishing eliminates lead leaching.
