Indoor air mercury (7439976) concentrations following the application of interior latex paint and the forms of mercury released were evaluated. Thirty seven homes were examined; of those, 21 homes were painted with mercury containing paint a median of 86 days earlier and 16 homes were not recently painted with mercury containing paint. Paint samples from the exposed homes contained a median of 210 milligrams mercury per liter. The median air mercury concentration was 0.3 micrograms per cubic meter in the exposed homes, versus virtually nondetectable levels in the unexposed homes. Among the exposed homes, there were seven in which paint containing less than 200 milligrams mercury per liter had been applied. In these homes, the median air mercury concentration was 0.2 micrograms per cubic meter. Six exposed homes had air mercury concentrations greater than 0.5 micrograms per cubic meter. The form of mercury released into the air was elemental mercury. Small traces of methylethylmercury and monomethylmercury (16056341) were also identified. The authors conclude that potentially hazardous mercury exposure may occur in homes recently painted with paint that contains mercury concentrations of less than 200 milligrams per liter.
