Analysis of enzymes as bioindicators on the combinatory effects of the mixtures of diflubenzuron and p-chloroaniline in tilapia in the presence of soil. Repositório Alice
DANTZGER, D. D.; JONSSON, C. M.; AOYAMA, H..
Introduction. Oreochromis niloticus (Nile tilapia) is the most produced and consumed fish in Brazil. Many fish farming use Diflubenzuron (DFB) as insecticide to control parasites responsible for diseases in these fish. This insecticide degradation generates p-chloroaniline (PCA), a potentially carcinogenic and mutagenic compound. Objectives The objective of this study was to evaluate the enzymes catalase (CAT) and transaminases (TGO and TGP) as water toxicity bioindicators using as experimental model the tilapia fish, exposed for 96 h to different combinatory concentrations of DFB and PCA mixtures, in presence of soil. Material and Methods. Samples of tilapia liver were homogenized and the supernatant was used for the biochemical analyses of enzyme...

Evaluation of the toxicity of the mixture of diflubenzuron and p-chloroaniline in tilapia fish in the presence and absence of soil. Repositório Alice
DANTZGER, D. D.; JONSSON, C. M.; NUNES, A. A. S.; AOYAMA, H..
aBSTRACT: Several chemicals occur together in the environment as a result of different sources. However, in the great majority of risk assessments only a single chemical is considered. Diflubenzuron (DFB), the most used compound to combat parasites in aquaculture, can be toxic for non-target species. When degraded, it generates p-chloroaniline (PCA), a potentially carcinogenic and mutagenic compound. This study analyzed the activity of the enzymes: Catalase (CAT), acid and alkaline Phosphatase (ACP/ALP) of the gills of the Tilapia fish (Oreochromis niloticus) exposed to different concentrations of the mixture of DFB and PCA in the presence and absence of soil.

Soil influence on the combinatory effect of mixtures of diflubenzuron and p-chloroaniline in tilapia and analysis of bioindicators. Repositório Alice
DANTZGER, D. D.; JONSSON, C. M.; AOYAMA, H..
The use of agricultural products has been the main way to combat parasites in aquaculture, and diflubenzuron is the most used compound. This can be toxic to non-target species and, when degraded, generates p-chloroaniline, a potentially carcinogenic and mutagenic metabolite to humans. The objective of this study was to evaluate the enzymes catalase and the Alanine aminotransferase and aspartate amino transferase as water toxicity bioindicators using as experimental model the tilapia fish, exposed for 96 hours to different combinatory concentrations of Diflubenzuron and p-chloroaniline mixtures, in presence and absence of soil. Samples of tilapia liver were homogenized and the supernatant was used for the biochemical analyses of enzyme activities. Our...
