Procymidone Residues in an Agricultured Area / 日本農村医学会雑誌

ABSTRACT

The amount of pesticide residues in the soil was investigated in two fields. About 0.05-0.14μg/g-dry of fungicide procymidone (Sumirex<SUP>TM</SUP>) were detected from the soil, where fuming with procymidone had been ceased for about a year.<BR>Measurements have been carried out for the subsequent three years with the result that the second half-life of procymidone in the soil was estimated at about 1.5 years.<BR>Procymidone residues ranging from 0.005 to 0.017μg/g-raw were detected in the vegetables grown in these fields, but not in strawberries.<BR>These data suggested that procymidone falls under the category of long-lived organo-chlorine pesticides.<BR>It is necessary to study further on the environmental behavior and the toxity of procymidone, as procymidone residues in foodstuffs are reported repeatedly and the chemical is still on the market.
