H.10 Database
The database that lists all of the studies, values, with references is presented as Table
H.9-1 through Table H.15-4 in the following pages.
Abbreviations in these tables:
soil conc bckd: the concentration of the chemical in the control soil samples
soil conc contam: the concentration of the chemical in the soil treated with the chemical
tissue conc bckg: the concentration of the chemical in the control tissue samples of the
crop
tissue conc contam: the concentration of the chemical in the tissue of the crop grown in
the soil treated with the chemical
contam: the related sample treated with the chemical
wt: weight
dw: dry weight
wet w: wet weight
ww: wet weight
Calculation:
tissue conc contam dry wt – tissue conc bckg dry wt
Uptake factor (contam) dry wt = ----------------------------------------------------------------------
soil conc contam – soil conc bckd
Uptake factor (contam) wet wt plant/dw soil = Uptake factor (contam) dry wt × dry-to-wet
wt conversion factor
Uptake factor (contam) wet wt plant/dw soil
Uptake factor (contam) ww plant/wet w soil =---------------------------------------------------------
dry-to-wet weight fraction for soil (0.8)
