Which of the following is NOT a method for assessing lead risk?

Testing air quality for lead particles is not typically recognized as a method for assessing lead risk in terms of evaluating lead exposure in housing or environmental settings. The most common methods for assessing lead risk involve evaluating sources of lead exposure that are directly related to residential conditions.

Visual inspection for deteriorating paint identifies potential lead hazards from paint that is peeling, chipping, or otherwise deteriorating, particularly in homes built before 1978 when lead-based paints were commonly used. Blood testing for lead levels is a crucial method in determining an individual's exposure to lead and potential poisoning, especially in children, as it directly measures the amount of lead in the bloodstream. Checking for lead plumbing is another critical assessment method because lead pipes or plumbing fixtures can leach lead into drinking water, posing significant health risks.

In contrast, while air quality testing can measure particulate matter and other pollutants, it is less specific and not the standard practice for assessing lead exposure from common residential sources. Thus, air quality testing for lead particles does not constitute a recognized method for lead risk assessment in relation to the most common sources of lead exposure.
