    individual forms and amounts of these metabolites found in the urine and feces vary among species, studies, and dose (7-12). Metabolic studies of atrazine metabolism in humans have identified trace amounts of free parent compound (6) in urine. To date, no conjugated metabolites of atrazine have been reported in human studies.

    Didealkyl atrazine was the most abundant metabolite detected in the urine and plasma samples (∼1000 μM in 24-h urine and ∼100 μM in plasma following the highest dose of atrazine), with lesser quantities of mono N-dealkylated metabolites and thio conjugates of atrazine observed.

    Determination of herbicides and a metabolite in human urine

    Atrazine urinary metabolites consisted of bi-dealkylated (80%), deisopropylated (10%), deethylated (8%), as well as unmodified atrazine (2%), as shown in Fig. 1. The metabolites took nearly 24 h to be eliminated via urine, 50% of the amount being excreted in the first 8 h . Download : Download full-size image; Fig. 1.

    Determination of herbicides and a metabolite in human urine

    A method was developed to determine simazine, atrazine and their metabolite, 2-chloro-4,6-diamino-1,3,5-triazine, in urine. The presence of these herbicides in urine may reflect possible exposure

    The metabolites DDE and endrin ketone were not detected in any urine samples. Of the parent compounds, DDT, methoxychlor, and endrin as well as the metabolites DDE, DDD, and endosulfan sulfate appear to be readily excreted into sweat as they are found in over half of the participants examined (Table 5 ).

    A method for the determination of triazines (simazine, atrazine) and their metabolite 2-chloro-4,6-diamino-1,3,5-triazine by liquid chromatography–mass spectrometry with electrospray ionization (LC–MS/ESI) in human urine is described. The method outlines the sample preparation, which involves protein precipitation with acetonitrile and solid-
