The frequency of HAB occurrence is on the rise and HABs have been associated with human health impacts including skin rashes, asthma exacerbation, gastrointestinal illness, and liver damage. Most algae species are not harmful, but sometimes certain types can bloom in excessive amounts and cause severe damage to human health, aquatic ecosystems, and local economies.
