Harmful Algal Blooms (HABs) are commonly caused by the rapid growth of cyanobacteria in fresh waterways, which many people rely on for drinking water. When a HAB occurs, a variety of cyanotoxins can be produced and released into sources of drinking water, which can make people sick or die if not properly treated. Two of the most common toxins are microcystin-LR (MC-LR) and anatoxin-a (A-a), for which the World Health Organization (WHO) recommends a maximum allowable concentration of 1 µg/L in drinking water to avoid health risks. The recommendation for maximum allowable concentration was calculated specifically for microcystins, but is …
