leachate as well in a concentration
of 11% of the applied r.a.. Based
on the relative molar mass of 1.4,
the averaged annual concentration
amounts to 4.4 µg/l.
At least five other (polar)
metabolites are found in amounts
>0.1 µg/l as chlorothalonil
equivalents.
Total amounts of radioactivity
equivalents (annual average)
amounted to: 31.8 and 25.6 µg/l
for both lysimeters respectively in
the first year and 4.94 and 4.86
µg/l in the second year. Maximum
individual concentrations of a.i.
equivalents were 79 and 59 µg/l
for the two lysimeters respectively
in the first year. No parent
compound and none of the main
metabolites available as reference
substance (SDS-3701; SDS-
19221; SDS-47523; SDS-47524;
SDS-47525; SDS-66882 and
SDS-67042) were detected by
radio HPLC, except for SDS-
46851, detected in a selected
sample (19-11-96) at 0.2 µg/l.
