Metabolic fates of herbicides in animals

THE FIRST STEPS OF HOGARTH'S HARLOT'S PROGRESS

“…Most commentators content themselves with the suggestion that the harlot is showing off a watch that she has stolen from a client of the previous night, while Paulson also reads it metaphorically that time is running out. 13 Both interpretations depend upon an understanding of a narrative context which was, as we now know, originally lacking for this scene. And the watch itself provides one final piece of evidence of the belated conversion of the scene into a narrative.…”

Determination of chlorinated phenols in brewing liquor and beer using SPE.

“…Jejich hlavními zdroji jsou jednak ochranné prostředky užívané zejména v zemědělství (pesticidy, herbicidy, fungicidy), jednak odpadní produkty chemického, dřevařského a papírenského průmyslu. Chlorované fenoly se do životního prostředí mohou dostávat buď přímou aplikací insekticidů a fungicidů na bázi pentachloru, nebo jako degradační produkty vznikající metabolickým rozkladem chlorovaných pesticidů obsahujících ve své molekule substituované fenoly (chlorfenoxyalkanové kyseliny a nitrofenoly), odbouráváním herbicidů (diuron, chloroxuron na bázi močoviny) a přeměnou organofosfátů, chlorovaných benzenů a nitrobenzenů [1,2,3].…”

“…in the petroleum industry and pulp and paper industry and in the production of plastics, dyes, pharmaceuticals and in agriculture as pesticides, herbicides, fungicides. In the environment these compounds can also occur as a result of application of insecticides and fungicides based on pentachlorine or as a result of hydrolysis, oxidation and microbial degradation of chlorinated pesticides containing in their molecule substitute phenols (chlorinated phenoxy alkanoic acid and nitrophenols) or by the degradation of herbicides (diuron, chloroxuron) or else by the conversion of organophosphates, chlorinated benzenes and nitrobenzenes [1,2,3].…”

Use of ion cluster analysis in a metabolic study of pencycuron, a phenylurea fungicide, in rabbits

“…At present, information concerning the metabolic behavior of pencycuron in mammals is scanty. On the other hand, several studies on the metabolic fate of urea herbicides in mammals have been reported (Paulson, 1975). The major metabolic pathways of methylor methoxysubstituted ureas are demethylation and/or demethoxylation.…”
