where CRPHR is a consumption rate (L$day1
) that represents an
exceedance of the ADI and therefore a health risk to a 70 kg individual,
ADI is measured in mg kg1
$day1
, concentration is
measured in mg L1
, and 0.001 is a unit conversion for mass in
numerator versus denominator. The CRPHR was computed for both
the maximum and average concentrations of the compound
reported in the literature. CRPHR computations are presented in
graphical form (Fig. 1) to allow for comparison of the risk posed by
maximum and average concentrations in the freshwater environment.
Fig. 1 shows the CRPHR at the maximum concentration as
a point and, when the median or mean was available, extends an
error bar to the CRPHR at the average concentration.
