4 Pharmacology and Biochemistry
4.1 Absorption, Distribution and Excretion

... The atrazine (ATZ) concentrations in urine samples of the workers collected from an atrazine plant were determined by /a gas chromatograph-electron capture detector/ method /for detecting ATZ and its metabolites (deethylatrazine (DEA), deisopropylatrazine (DIA), deethyldeisopropylatrazine (DEDIA)) in human urine/. The concentration ranges were 0.003 -0.301 mg/L for DEDIA, 0.005 -0.011 mg/L for DEA, 0.006 -0.276 mg/L for DIA, and 0.005 -0.012 mg/L for ATZ.

... After atrazine ingestion, the urine and carcass of treated animals /contained/ atrazine and its metabolites, indicating that atrazine was absorbed through the GI tract. /Atrazine & metabolites/

4.2 Metabolism/Metabolites

Deethylatrazine (desethyl atrazine) is a metabolite of atrazine.

PMID:512229 ERICKSON MD ET AL; J AGRIC FOOD CHEM 27 (4): 743-6 (1979)


Three species of Pseudomonas capable of utilizing atrazine as a sole source of carbon were isolated by enrichment from soil with a long history of atrazine application. Atrazine was metabolized via N-dealkylation with preferential formation of deisopropylatrazine over deethylatrazine. Two of the species were able to carry out the following incubation in glucose-supplemented mineral salts medium.

Behki RM and Khan Su; J Agric Food Chem 34 (4): 748-9 (1986)


Deethylatrazine is primarily a mammalian metabolite but can be produced in plants and bacteria. Dealkylation of the ethyl group from the 4 position of the triazine ring yields deethylatrazine.

USEPA; Revised Toxicology Chapter; Interim Reregistration Eligibility Decision (IRED) for Atrazine (1912-24-9). Available from, as of Nov 20, 2003: https://www.epa.gov/oppsrrd1/reregistration/atrazine/


Manganese enhanced atrazine transformation by the fungus Pleurotus pulmonarius when added to a liquid culture medium at concentration of up to 300 uM. Both N-dealkylated and propylhydroxylated metabolites accumulated in the culture medium, with the former accumulating to a greater extent than did the latter. Lipid peroxidation, oxygenase and peroxidase activities, and the cytochrome P-450 concentration increased. In addition, an increase in the spectral interactions between atrazine and components in the cell extract was observed. Antioxidants, mainly nordihydroguaiaretic acid, which inhibits lipoxygenase, peroxidase, and P-450 activities, and piperonyl butoxide, which inhibits P-450 activity, inhibited atrazine transformation by the mycelium. It is suggested that the stimulation of oxidative activity by manganese might be responsible for increasing the biotransformation of atrazine and for nonspecific transformations of other xenobiotic compounds.
