Journal ArticleDOI
Effects of dietary methylmercury on liver and kidney histology in the neotropical fish Hoplias malabaricus.
Maritana Mela,Marco Antonio Ferreira Randi,Dora Fix Ventura,Carlos Eduardo Veiga de Carvalho,E. Pelletier,C.A. Oliveira Ribeiro +5 more
TL;DR: The morphological effects of methylmercury in liver and kidney of Hoplias malabaricus feeding contaminated prey fish over 70 days are investigated, demonstrating that the sensitivity of fish cells to methylMERcury exposure is higher than it has been previously described in the literature.
Journal ArticleDOI
Effects of dietary Pb(II) and tributyltin on neotropical fish, Hoplias malabaricus: histopathological and biochemical findings.
I.S. Rabitto,J.R.M. Alves Costa,H.C. Silva de Assis,Émilien Pelletier,F.M. Akaishi,Adilson dos Anjos,Marco Antonio Ferreira Randi,C.A. Oliveira Ribeiro +7 more
TL;DR: This work is the first to report detailed in vivo toxic effects in tropical fish, H. malabaricus, after dietary sublethal exposure to Pb(II) and TBT, and the cholinesterase activity was inhibited in muscle after 14 doses.
Journal ArticleDOI
Bioaccumulation of chlorinated pesticides and PCBs in the tropical freshwater fish Hoplias malabaricus: histopathological, physiological, and immunological findings.
A. L. Miranda,H. Roche,Marco Antonio Ferreira Randi,Manoel Lima de Menezes,C.A. Oliveira Ribeiro +4 more
TL;DR: The present data suggest an immunosuppression in the individuals from Ponta Grossa Lake after exposure to POPs, which are bioavailable, induce severe damages in target organs such as the liver, and can disturb the immune system of the trahira.
Journal ArticleDOI
Hematological findings in neotropical fish Hoplias malabaricus exposed to subchronic and dietary doses of methylmercury, inorganic lead, and tributyltin chloride.
C.A. Oliveira Ribeiro,Francisco Filipak Neto,Maritana Mela,Paulo Henrique da Silva,Marco Antonio Ferreira Randi,I.S. Rabitto,J.R.M. Alves Costa,E. Pelletier +7 more
TL;DR: Changes in hematological and blood indices could highlight some barely detectable metal effects in fish after laboratory exposure to contaminated food, but their application in field biomonitoring using H. malabaricus will need more detailed studies and a careful consideration of environmental parameters.
Journal ArticleDOI
Effects of the herbicide atrazine in neotropical catfish (Rhamdia quelen).
Maritana Mela,Izonete Cristina Guiloski,Halina Binde Doria,Marco Antonio Ferreira Randi,C.A. de Oliveira Ribeiro,Luciana Barbosa Pereira,A.C. Maraschi,Viviane Prodocimo,Carolina A. Freire,H.C. Silva de Assis +9 more
TL;DR: The results suggest that ATZ, represents a potential ecotoxicological hazard and can be hepatotoxic and nephrotoxic even low concentrations, and is likely to cause histopathological, biochemical and physiological changes in R. quelen.
