Figure 5.

Temporal variability of the sum of DEHP metabolites (∑DEHP) and of MEP from longitudinal samples of 9 mothers, plotted versus the days since the first sample collection. First four or five samples were typically collected once a week during the 2nd trimester and the next four or five samples were typically collected once a week during the 3rd trimester. Circle points represent first morning voids (FMVs) and black diamond points 24-hour samples. Only FMVs were used to compute coefficient of variation (CV). The degree of within-subject variability varies not only between participants, but also by metabolites within participants.
