Resumen:
Cyanobacterial blooms have serious adverse effects on human and environmental health. In Latin America, one
of the main world’s freshwater reserves, information on this phenomenon remains sparse. To assess the current
situation, we gathered reports of cyanobacterial blooms and associated cyanotoxins in freshwater bodies from
South America and the Caribbean (Latitude 22◦ N to 45◦ S) and compiled the regulation and monitoring procedures implemented in each country. As the operational definition of what is a cyanobacterial bloom remains
controversial, we also analyzed the criteria used to determine the phenomena in the region. From 2000 to 2019,
blooms were reported in 295 water bodies distributed in 14 countries, including shallow and deep lakes, reservoirs, and rivers. Cyanotoxins were found in nine countries and high concentrations of microcystins were
reported in all types of water bodies. Blooms were defined according to different, and sometimes arbitrary
criteria including qualitative (changes in water color, scum presence), quantitative (abundance), or both. We
found 13 different cell abundance thresholds defining bloom events, from 2 × 103 to 1 × 107 cells mL− 1. The use
of different criteria hampers the estimation of bloom occurrence, and consequently the associated risks and
economic impacts. The large differences between countries in terms of number of studies, monitoring efforts,
public access to the data and regulations regarding cyanobacteria and cyanotoxins highlights the need to rethink
cyanobacterial bloom monitoring, seeking common criteria. General policies leading to solid frameworks based
on defined criteria are needed to improve the assessment of cyanobacterial blooms in Latin America. This review
represents a starting point toward common approaches for cyanobacterial monitoring and risk assessment,
needed to improve regional environmental policies.
