What is the main concern when evaluating lead in older homes?

The primary concern when evaluating lead in older homes is the use of lead-based paint. Many homes built before 1978 were painted with lead-based products, making this a significant risk factor for lead exposure, particularly for young children and pregnant women. Lead can chip, peel, or dust from painted surfaces, which can be ingested or inhaled, leading to serious health issues such as developmental delays and cognitive impairments.

While the presence of lead pipes is also a concern due to potential lead exposure from drinking water, lead-based paint remains a more prevalent hazard in the context of residential properties. Poor ventilation and asbestos contamination can represent health risks, but they are not directly related to lead exposure in the same context as lead-based paint. Therefore, understanding the risks associated with lead-based paint is crucial for ensuring safety in the evaluation and remediation of older homes.
