What factor is NOT considered when evaluating dermal contact risk?

When evaluating dermal contact risk, distance from the site is not a factor that is typically considered. Dermal contact risk assessment focuses primarily on how contaminants come into contact with the skin, which is directly influenced by the concentration of contamination, the depth of contamination within the soil, and the type of soil present.

Concentration of contamination indicates how much of a harmful substance is present, which affects the potential for skin absorption. Depth of contamination is significant because it determines whether a person could come into contact with the contaminants during normal activities, such as digging. The type of soil can influence how contaminants may adhere to skin or clothing and how easily they can be absorbed.

Distance from the site, however, is less relevant in terms of dermal contact since it does not impact the actual exposure that occurs if an individual is already in contact with contaminated soil or materials. It is more relevant in scenarios assessing exposure to airborne contaminants or overall site safety rather than direct dermal contact.
