چکیده

Advected cyanobacteria, algal blooms and cyanotoxins have been increasingly detected in freshwater ecosystems. This review gives an insight into the present state of knowledge on taxonomy, dynamics, toxic effects, human ecological health implications East African Community lakes. The major toxigenic microalgae lakes include Microcystis, Arthrospira, Dolichospermum, Planktolyngbya Anabaenopsis species. Anatoxin-a, homoanatoxin-a, microcystins (MCs), cylindrospermopsin nodularin quantified water from below method detection limits to 81 µg L−1, with peak concentrations characteristically reported for wet season. In whole fish, gut, liver muscles, MCs found at 2.4 1479.24 μg kg−1, which can pose risks a daily consumer. While there no cases cyanotoxin-related poisoning humans, anatoxin-a (up 0.0514 kg−1) identified as proximal cause indiscriminate fish kills epornitic mortality algivorous Phoeniconaias minor (lesser flamingos). With unequivocal increase climate change variability, will frequency severity, this necessitate swift action towards mitigation nutrient-rich pollutants loading region.

Algal Blooms and Cyanotoxins in Jordan Lake, North Carolina

The eutrophication of waterways has led to a rise in cyanobacterial, harmful algal blooms (CyanoHABs) worldwide. The deterioration of water quality due to excess algal biomass in lakes has been well documented (e.g., water clarity, hypoxic conditions), but health risks associated with cyanotoxins remain largely unexplored in the absence of toxin information. This study is the first to document ...

Human fatalities from cyanobacteria: chemical and biological evidence for cyanotoxins.

An outbreak of acute liver failure occurred at a dialysis center in Caruaru, Brazil (8 degrees 17' S, 35 degrees 58' W), 134 km from Recife, the state capital of Pernambuco. At the clinic, 116 (89%) of 131 patients experienced visual disturbances, nausea, and vomiting after routine hemodialysis treatment on 13-20 February 1996. Subsequently, 100 patients developed acute liver failure, and of th...

Cyanobacteria and Cyanotoxins: From Impacts on Aquatic Ecosystems and Human Health to Anticarcinogenic Effects

Cyanobacteria or blue-green algae are among the pioneer organisms of planet Earth. They developed an efficient photosynthetic capacity and played a significant role in the evolution of the early atmosphere. Essential for the development and evolution of species, they proliferate easily in aquatic environments, primarily due to human activities. Eutrophic environments are conducive to the appear...
