Although it is known that tannery effluents constitute highly toxic pollutants whose effects in humans represent public health problems in several countries, studies involving experimental mammalian models are rare. In this context, the objective of the present study was to assess the effect of the exposure to tannery effluent on the memory of male and(More)
The current study has assessed whether the oral and/or dermal exposure of C57Bl/6 J mice to tannery effluent (a complex pollutant consisting of xenobiotic mixtures) could damage their olfactory functions, as well as whether it changes their aversive behavior in the inhibitory avoidance test. Accordingly, the animals were distributed in groups which were(More)
This study aimed to evaluate the behavior of female C57Bl/6J mice exposed to tannery effluents diluted in drinking water. Female mice were divided into a control group, in which the animals received only drinking water, and experimental groups, which received raw tannery effluent in 7.5 and 15 % concentrations diluted in water (period of 60 days). In the(More)
Previous studies have shown the contamination of rivers and streams caused by tannery effluents (TE). However, the effects of TE on amphibians are still unknown. Thus, we evaluated whether the TE, even at low concentrations (0.2%), could cause asymmetric development (inferred through the fluctuating asymmetry indices (FA)) and changes in morphological(More)
