What can lead-tin solder potentially contaminate?

Metal surfaces
Food
Water sources
Electronic components

The correct answer is: Food

Lead-tin solder can potentially contaminate food due to the presence of lead, which is toxic and can pose serious health risks if ingested. When utilized in applications such as plumbing or electronics, if the solder comes into contact with food surfaces, it can leach lead into the food. This is particularly concerning in household environments where solder is used in appliances or containers that may come into contact with food items. While lead-tin solder can also pose a risk to water sources and electronic components through contamination, the most direct and impactful risk to human health is through food contamination. Therefore, the consideration of safe materials in food preparation areas is crucial to prevent lead exposure.
