Background:

Before the events of cyanobacteria toxic blooms are widespread and are increasing in frequency globally, with negative effects on human health, pets, cattle, and wildlife, we integrated the information on the subject for general knowledge, as these events will increasingly have a greater incidence and frequency in a context of global warming.

Goals:

To reveal the environmental impacts of cyanotoxins, their causes, and acknowledge the need for knowledge about them in order to implement measures that will reduce their negative effects.

Methods:

We present a review of several studies encompassing historical aspects and incorporating the first studies into the current context, in order to enumerate the most frequent cyanotoxins in inland water.

Results:

We discuss the symptoms that cyanotoxins cause in vertebrates, as well as reference levels to avoid intoxication by ingestion or contact; the methods used for detection, and the effects on aquatic ecosystems.

Conclusions:

We draw attention to the need for integral management of algal blooms and syste matic monitoring.
