Once absorbed by humans, atrazine is rapidly distributed and metabolized via dealkylation with a biological elimination half-life of 10.8 to 11.2 hours.
Most of the atrazine and/or its metabolites is found in the red blood cells
Atrazine has low acute toxicity, however some metabolites of atrazine (desethyl- and desisopropylatrazine) are thought to have higher acute toxicity.

The toxicity of the herbicide can cause deleterious effects on the respiratory . . .
