TLDR
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.About:

Effects of microcystins on fish
TL;DR: It appears that MC concentrations found in nature can potently affect several trophic levels in the aquatic ecosystems, in particular by inducing failure of sensitive stages to develop and accumulating in the food chains.

Cyanobacterial toxins--occurrence, biosynthesis and impact on human affairs.
Elke Dittmann,Claudia Wiegand +1 more
TL;DR: An overview about the ecostrategies of the diverse toxin-producing species and about the genes and enzymes that are involved in the biosynthesis of the cyclic peptides are given.
Journal ArticleDOI
Accumulation of cyanobacterial toxins in freshwater "seafood" and its consequences for public health: A review
TL;DR: Risks of exposure to cyanotoxins in food are sometimes underestimated and risk assessments should acknowledge this and investigate the partitioning of exposure between drinking-water and food, which may vary depending on local circumstances.
Journal ArticleDOI
Guidance values for microcystins in water and cyanobacterial supplement products (blue-green algal supplements): a reasonable or misguided approach?
TL;DR: There is a need for improved kinetic data of microcystins in humans and for discussion concerning uncertainty factors, which may result in a lowering of the present guidance values and an increased routine control of water bodies and food supplements for toxin contamination.
Journal ArticleDOI
A review of cyanobacterial odorous and bioactive metabolites: Impacts and management alternatives in aquaculture
TL;DR: This review summarizes those cyanobacterial secondary metabolites that can cause undesirable tastes and odors (odorous metabolites) or are biochemically active (bioactive metabolites) in marine and freshwater, extensive and intensive aquaculture systems.

Zur Vervollkommnung der quantitativen Phytoplankton-Methodik
TL;DR: In this paper, the main aim is to describe the counting-chamber method and the numerous difficulties encountered in quantitative plankton research are discussed and ways of avoiding them are described together with improvements of technique that save time.

TL;DR: The state of knowledge regarding the principal considerations in the design of programmes and studies for monitoring water resources and supplies and describes the approaches and procedures used as mentioned in this paper, and the information needed for protecting drinking water sources and recreational water bodies from the health hazards caused by cyanobacteria and their toxins.

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
The toxins of cyanobacteria.
TL;DR: On May 2, 1878, George Francis of Adelaide, Australia, published the first scholarly description of the potentially lethal e-ects produced by cyanobacteria, sometimes called blue-green algae or, more colloquially, pond scum.
