REHS RS Solid And Hazardous Waste Practice Test

Lead-based paint was commonly used in homes built before 1978. As this paint ages, chips and creates dust that can contaminate surfaces and indoor environments. Young children are especially at risk because they tend to chew on objects and put hands or dust into their mouths, leading to lead exposure. Lead poisoning can cause serious neurodevelopmental problems, such as reduced IQ, attention and learning difficulties, and behavioral issues. Adults can be affected too, but the health impact on kids is the most notable and well-established consequence in older housing. Because pre-1978 construction is specifically associated with lead-based paint and related exposure, lead poisoning is the health condition most linked to these homes. The other conditions listed do not have the same direct connection to older housing materials.
