Second Fundão Dam Rupture Science Meeting: Updating the science.

The second Fundão Dam Rupture Science Meeting was held in Ouro Preto, Minas Gerais, Brazil, on 21 and 22 September 2022. A total of 100 delegates attended the meeting, which featured high-quality oral presentations and posters over the two days and lively discussions of the science presented. The meeting resulted in nine papers being published in this special series. In the discussion, it was commented that the first meeting had been more a meeting of competitive perspectives but that the second meeting featured a more collaborative sharing of knowledge. Also, there had been substantial improvement in ways to deal with the lack of pre-event data and account for other stressors in the system, and as a result, stronger conclusions regarding the recovery rates of the system were able to be made. Importantly, there was no evidence for a feasible "time bomb" of a future catastrophic release of contaminants, but it was agreed that different scenarios continue to be researched.

Valores hematológicos e bioquímicos de pinguins-de-Magalhães em reabilitação no Espírito Santo, sudeste do Brasil / Hematological and biochemical values of Magellanic penguins in rehabilitation in Espírito Santo, southeastern Brazil

Este trabalho apresenta valores hematológicos e bioquímicos de pinguins-de-Magalhães (Spheniscus magellanicus) juvenis que arribaram no Espírito Santo e Rio de Janeiro, litoral sudeste do Brasil, e foram encaminhados a reabilitação. Os valores médios obtidos foram: eritrócitos 2.55±0.54 milhões/µL; hemoglobina 13,37±3,91g/dL; hematócrito 41,5±0,04%; proteína plasmática 6,34±0,81g/dL; leucócitos 16.301±6.402/µL; trombócitos 20.516±4.591 células/µL; volume corpuscular médio (VCM) 172,0±53,0 fL; concentração de hemoglobina corpuscular média (CHCM) 26,41±0,02%; alanina transaminase (ALT) 50,0±17,89 U/L; ácido úrico 8,93±3,0mg/dL; albumina 1,68±0,53g/dL; cálcio 9,7±0,57mg/dL; fósforo 10,39±8,5mg/dL e glicose 211,6±30,3mg/dL. Valores de eritrócitos, VCM e CHCM foram discrepantes em relação aos valores de referência atuais. Valores de leucócitos e trombócitos tem significado inconclusivo. Hematócrito, hemoglobina, proteína plasmática e valores bioquímicos forneceram importante contribuição para o estabelecimento de parâmetros de referência.(AU)

This paper reports hematological and biochemical values of juveniles Magellanic penguins (Spheniscus magellanicus) stranded in Espírito Santo and Rio de Janeiro, Southeastern Brazil, that were sent for rehabilitation. The average values were: erythrocytes 2.55±0,54 milhões/µL, hemoglobin 13.37±3,91g/dL, hematocrit 41.5±0.04%, plasma protein 6.34±0.81g/dL, leukocytes 16,301±6,402/µL, thrombocytes 20,516±4,591 células/µL3, mean cell volume (MCV) 172.0±53.0 fL, mean cell hemoglobin concentration (MCHC) 26.41±0.02%, alanine transaminase (ALT) 50.0±17.89 U/L, uric acid 8.93±3.0mg/dL, albumin 1.68±0.53mg/dL, calcium 9.7±0.57mg/dL, phosphorus 10.39±8.5mg/dL and glucose 211.6±30.3mg/dL. Values of erythrocytes, MCV and MCH were discrepant in relation to the current reference values. Leukocytes and thrombocytes values has meant inconclusive. Hematocrit, hemoglobin, plasma protein and biochemical values provided important contribution for the establishment of reference parameters.(AU)
