| Environmental Fate | TERRESTRIAL FATE: SWEP WAS INCUBATED @ 28 DEG C WITH NIXON
SANDY LOAM (PH 5.5). AFTER 40 DAYS, SOME SWEP REMAINED INTACT; BUT TLC
INDICATED THAT A PORTION WAS TRANSFORMED TO A VARIETY OF PRODUCTS.
HERBICIDAL CARBAMATES ARE BECOMING INCREASINGLY IMPORTANT THEY
ARE OF LOW MAMMALIAN TOXICITY, HAVE RELATIVELY SHORT RESIDUAL LIFE
IN SOIL, & ARE READILY DEGRADED BY NONTARGET ORGANISMS
/METHYLCARBAMATES
FROM THE DATA PRESENTED IN REVIEW, IT APPEARS THAT MOST, IF NOT ALL,
OF KNOWN CARBAMATE METABOLITES ARE LESS TOXIC TO THE ENVIRONMENT
THAN PARENT MOLECULES. CARBAMATE HERBICIDES
