This work describes the accumulation and distribution of the herbicide atrazine in soil, water, and roots from three wetland model systems using the monocots Typha domingensis, Sagittaria lancifolia, and Echinochloa pyramidalis. Results were analyzed from a 3(3) full factorial experimental design, in order to describe the effect of accumulation of atrazine and times of exposure in the species evaluated. We found that accumulation depends on the species and the herbicide concentration; about 30% was accumulated in soil, 40% in roots, and 10-20% in water. By the end of the experiment, E. pyramidalis accumulated 8.47 mg/l of atrazine and 14.39 mg/l T. domingensis; in all cases, adsorption accounted for 1.4%, fitting a Langmuir model with a k(d) of 14.47.
