Abstract EN
Water samples were collected during 3 years (2004–2007) at three sampling sites in the Rio de la Plata estuary.
Thirteen biological, physical, and chemical parameters were determined on the water samples.
The presence of microcystin-LR in the reservoir samples, and also in domestic water samples, was confirmed and quantified.
Microcystin-LR concentration ranged between 0.02 and 8.6 μg.L−1.
Principal components analysis was used to identify the factors promoting cyanobacteria growth.
The proliferation of cyanobacteria was accompanied by the presence of high total and fecal coliforms bacteria (>1500 MNP/100 mL), temperature ≥25∘C, and total phosphorus content ≥1.24 mg·L−1.
The observed fluctuating patterns of Microcystis aeruginosa, total coliforms, and Microcystin-LR were also described by probabilistic models based on the log-normal and extreme value distributions.
The sampling sites were compared in terms of the distribution parameters and the probability of observing high concentrations for Microcystis aeruginosa, total coliforms, and microcystin-LR concentration.
