"Over the past 30 years, CPSC has been at the forefront of protecting the nation's children from the hazards associated with lead," said CPSC Chairman Hal Stratton. "The ban of lead-cored candlewicks should give parents with young children peace of mind that the burning of votive, pillar or container candles will not emit a dangerous toxin."
A CPSC investigation found that despite a voluntary industry agreement in the 1970s to remove lead from candle wicks, a small percentage of candles sold in the past several years still contained lead-cored wicks. CPSC staff found that some lead-cored wicks could emit relatively large amounts of lead into the air during burning. Children may then inhale the vaporized lead, placing them at risk. Children may also be exposed to lead by mouthing objects on which lead has settled or by handling such objects and then mouthing their hands.
Some of the candles tested by CPSC staff emitted lead levels in excess of 3,000 micrograms per hour - about seven times the rate that could lead to elevated levels of lead in a child. CPSC estimates that an indoor air lead level of 430 micrograms per hour from burning candles could result in hazardous exposure to children.
Lead poisoning in children is associated with behavioral problems, learning disabilities, hearing problems and growth retardation. Although the primary source of lead poisoning in the United States is lead from paint in older homes, lead accumulates in the body, and even exposure to small amounts of lead can contribute to the overall level of lead in the blood.
Safe alternatives to lead-cored wicks, including zinc, synthetic fibers, cotton and paper, are used by most candle and candle wick manufacturers. Currently, candles that use a metallic core in the wick most likely contain zinc. Because consumers cannot tell if a metal- cored wick contains lead or an alternative, consumers may wish to contact the retailer for information about the materials used in their candles.
The CPSC was petitioned to ban candlewicks containing lead cores and candles with such wicks by Public Citizen, the National Apartment Association, and National Multi Housing Council on February 20, 2001. The ban against manufacturing, importing, or selling candles with lead wicks will become effective in October 2003.
