a Method detection limits are equal to 3 times the average standard deviation
(1 sigma) of 3 sets of 7 replicate analyses performed on three nonconsecutive
days.
b Results are for 5-mL water samples.
c Results are for 5-g soil samples.
d Results are for 1-g samples.
e Results are for 0.2-g samples of cod liver oil.
f Int = spectral interferences prevented accurate integrations.
g NA = compound not significantly present in vacuum distillate.
