Which of the following statements about lead in housing is accurate?

The statement regarding lead exposure can result from various sources is accurate because lead can be found in a range of products and environments beyond just old homes. While lead-based paint and lead pipes in older houses are common sources of lead exposure, lead can also be present in imported toys, jewelry, pottery, and old plumbing systems in newer homes, as well as in soil contaminated by historical uses of lead in gasoline or industrial activities. This understanding highlights the importance of considering multiple avenues of potential lead exposure rather than limiting the focus to just one type of hazard.

The other statements do not accurately represent the broader context of lead hazards. For instance, while lead hazards are more prevalent in older homes due to the historical use of lead-based paints, this does not mean they are exclusively found there. Additionally, lead paint can pose serious risks even when intact if it deteriorates or is disturbed. The idea that lead poisoning is reversible is misleading; while some effects can be mitigated with treatment, the damage caused, especially in children, can have lasting impacts.
