There are a number of common misconceptions about harmful algal blooms, including that they occur only to summer water temperatures, that they are unique to nutrient-rich (nutrient-rich) systems, that they are caused entirely by elevated phosphorus concentrations, and that they are most likely to occur to stable (stratified) waters column conditions. The most potentially harmful misconception is that harmful algal blooms can be cured by treatment of basic copper sulphate.
These "typical conditions" do not always lead to harmful algal blooms, and elevated levels of cyanobacteria toxins may occur even in waters with limited nutrients or in environmental conditions that deviate from the "norm". To complicate matters, not all cyanobacteria are associated with harmful algal blooms, cyanotoxin producers may not always produce cyanotoxins, and the taste and odor compounds normally associated with harmful algal blooms may be produced by non-hazardous algal blooms. Therefore, the only way to know for sure whether a water body is exposed to or at risk of harmful algal blooms is to collect appropriate data. This includes.
Number and species of phytoplankton communities
Collection and analysis of chlorophyll a
Collection and analysis
Phosphorus (TP, SRP, DOP and DIP)
Nitrogen (nitrate and ammonia)
Measurement of taste and odor compounds
2-Methylisoborbitol (aka MIB)
Analyze the amount of microcyst in the water column.
To date, cyanotoxin testing has been very expensive and data turnover has been slow.
