In loading measurement, which unit is used to express loading?

• A. per square foot
• B. per square meter
• C. micrograms of lead per square foot
• D. grams per square foot

Answer: (B)

Loading measures how much lead is present on a surface for each unit of area. That means you express the amount of lead divided by the area of the surface. In EPA practice, metric units are standard for reporting, so using square meters as the area unit is the expected form. Therefore, expressing loading with the area unit per square meter fits the standard approach. Using per square foot would be using an imperial area unit, and the other choices mix area with mass units in less conventional ways for this context. So, per square meter is the best fit for loading measurement here.
