abstract = "Wastewater discharges from dairy industries can cause a range of
harmful effects in aquatic ecosystems, including a decline in
biodiversity due to species evasion. Therefore, it is important to
know the purification potential of rivers for the removal of
pollutants released in dairy wastewater (DWW). The hypothesis
adopted in this work was that the release of DWW into stretches of
the Ribeirao dos Pombos ~ River (S~ ao Paulo State, Brazil) might
trigger an avoidance response, resulting in fish migrating to
other regions, with the response being greater when the
self-cleaning potential of the river is smaller. Therefore, the
goals of the present study were to: (i) investigate how land use
and seasonality of the rainfall regime influence the quality of
the water in different areas of the river (P1: river source; P2:
urban region; P3: rural region); (ii) assess the potential of the
river to purify DWW; and (iii) evaluate the potential toxicity and
repellency of DWW to the freshwater fish Danio rerio, using acute
toxicity (mortality) and non-forced avoidance tests, respectively.
P1 was shown to be the most preserved area. The chemical
composition of the river varied seasonally, with higher
concentrations of Cl and SO4 2 at P3 during the rainy period. The
river purification potential for DWW was higher at P2, due to
greater microbiological activity (associated with higher BOD). The
DWW was more acutely toxic in water from P2. The avoidance
response was strongly determined by the concentration of DWW,
especially for water from P2. The high capacity for self-cleaning
at P2 did not seem sufficient to maintain the stability of the
ecosystem. Finally, the non-forced exposure system proved to be a
suitable approach that can assist in predicting how contaminants
may affect the spatial distributions of organisms.",
