Which of the following is NOT a common source of lead exposure?

Fresh fruits are not a common source of lead exposure. Lead exposure primarily comes from environmental sources that have a direct connection to human activities or materials. For example, lead-based paint was widely used in homes prior to its ban in the late 1970s, making it a significant source of lead exposure, especially for children in older homes. Leaded gasoline, although phased out in many countries, was once a major contributor to environmental lead levels, affecting air quality and soil contamination.

Soil can also be a significant source of lead, particularly in urban areas or near industrial sites, where lead particles can settle from the air or be present due to historical use of leaded products. Unlike these options, fresh fruits are typically safe from lead contamination, especially when they are grown in clean environments, as fruits do not inherently contain lead. Therefore, recognizing that fresh fruits do not serve as a source of lead exposure helps distinguish them from the more hazardous materials listed.
