TABLE 3.5
RESULTS FOR FRACTIONATION OF PENDIMETHALIN IN DRAIN WATER SAMPLES FROM MODEL AREAS. SAMPLES
WERE ANALYSED BEFORE CENTRIFUGING AND AFTER CENTRIFUGING AT 5000 RPM (4100 TIMES G-FORCE)
FOR 30 MINUTES. PENDIMETHALIN WAS THE ONLY PESTICIDE OF 31 INCLUDED IN THE ANALYSIS THAT WAS
FOUND IN CONCENTRATIONS ABOVE DETECTION LIMIT.
TABEL 3.5.
RESULTATER FOR FRAKTIONERING AF PENDIMETHALIN I DRÆNVANDSPRØVER FRA MODEL-OPLANDE. PRØVER
BLEV ANALYSERET FØR OG EFTER CENTRIFUGERING VED 5000 OMDREJNINGER PER MINUT (4100 GANGE
TYNGDEKRAFTEN) I 30 MINUTTER. PENDIMETHALIN VAR DET ENESTE PESTICID AF 31 INCLUDERET I ANALYSEN,
SOM BLEV FUNDET I KONCENTRATIONER OVER DETEKTIONSGRÆNSEN.
