Lead contamination in Flint, Michigan's water supply is bringing national attention to the topic of lead poisoning and the safety of resources we use every day. Pennsylvania's water supply is generally considered safe from lead poisoning. However, lead exposure and poisoning have been linked to paint, children's toys, and some art supplies.

According to the Pennsylvania Department of Health, lead-based paints present the most common threat to Pennsylvanians. Any home built before 1978 could contain lead paint. Exposure to lead poisoning can stem from swallowing or inhaling the paint.

Children are especially at risk for lead exposure. Their physical and mental health can be affected permanently.

Appearing on Thursday's Smart Talk is Dr. Loren Robinson, the Deputy Secretary for Health Promotion and Disease Prevention with the Pennsylvania department of Health.

Also, one of Central Pennsylvania's most popular attractions, especially at this time of year, could close without an influx of money.

Millions of migrating waterfowl stop at the Middle Creek Wildlife Management Area on the Lebanon-Lancaster County line near the end of every winter.

The Pennsylvania Game Commission is pushing for an increase in hunting license fees to generate money needed to maintain Middle Creek and for other expenses. License fees have not increased since 1999.

Game Commission Press Secretary Travis Lau explains on Thursday's Smart Talk.
