Sampling time is end of shift at the end of the work week for industrial exposure monitoring. Metals with timing “end of shift at the end of the work week” (meaning four or five consecutive days with exposure) are eliminated with half-lives longer than five hours. Such metals accumulate in the body during the work week; therefore, their timing is critical in relation to previous exposures.
