Question

question 7 1 pts one source of lead in some workplaces is ______.
∘ painting
∘ water
∘ blood
∘ food

Explanation:

In some workplaces, especially in industries related to painting (e.g., using lead - based paints in certain historical or specialized painting jobs), painting can be a source of lead exposure. Water, blood, and food are not typical sources of lead in workplaces in the context of this question. Blood is a medium that can carry lead but not a source of lead introduction in the workplace. Water and food are more related to general environmental or dietary lead exposure rather than workplace - specific sources in this context.

Answer:

A. Painting
