Journal ArticleDOI
Liver Failure and Death after Exposure to Microcystins at a Hemodialysis Center in Brazil
Elise M. Jochimsen,Wayne W. Carmichael,An Js,Cardo Dm,Cookson St,Holmes Ce,Antunes Mb,de Melo Filho Da,Lyra Tm,Barreto Vs,Sandra M.F.O. Azevedo,William R. Jarvis +11 more
TL;DR: Water used for hemodialysis can contain toxic materials, and its quality should therefore be carefully monitored.
Journal ArticleDOI
Human Fatalities from Cyanobacteria: Chemical and Biological Evidence for Cyanotoxins
Wayne W. Carmichael,Sandra M.F.O. Azevedo,Ji Si An,Renato J.R. Molica,Elise M. Jochimsen,Sharon Lau,Kenneth L. Rinehart,Glendon Reginald Shaw,Geoff Eaglesham +8 more
TL;DR: It is concluded that the major contributing factor to death of the dialyses patients was intravenous exposure to microcystins, specificallymicrocystin-YR, -LR, and -AR.
Journal ArticleDOI
Human intoxication by microcystins during renal dialysis treatment in Caruaru-Brazil
Sandra M.F.O. Azevedo,Wayne W. Carmichael,Elise M. Jochimsen,Kenneth L. Rinehart,Sharon Lau,Glendon Reginald Shaw,Geoff Eaglesham +6 more
TL;DR: Comparing victims symptoms and pathology with animal studies on these two cyanotoxins, leads us to conclude that the major contributing factor to death of the dialysis patients was intravenous exposure to microcystins, specifically microCystin-YR, -LR and -AR.
Journal ArticleDOI
Microcystin contamination in fish from the Jacarepaguá Lagoon (Rio de Janeiro, Brazil): ecological implication and human health risk
TL;DR: It is demonstrated that microcystins can accumulate in fish tissue used for human consumption and rates of ingestion routinely exceed the TDI guidelines as set by the WHO for drinking water.
Journal ArticleDOI
Microcystins (cyanobacteria hepatotoxins) bioaccumulation in fish and crustaceans from Sepetiba Bay (Brasil, RJ)
Valéria Freitas de Magalhães,Marcelo Manzi Marinho,Patrícia Domingos,Ariclécio Cunha de Oliveira,Simone M. Costa,Luiz Otávio Azevedo,Sandra M.F.O. Azevedo +6 more
TL;DR: It was verified that 19% of the animals' samples were above the limit recommended by WHO for human consumption, which refers to healthy adult, and data demonstrate that, although in low concentrations, there is already a contamination of fish and crustaceans from Sepetiba Bay.
