Harmful Algal Blooms

Harmful algal blooms (HABs) are large concentrations of harmful algae or cyanobacteria that can cause serious environmental, economic, and human health impacts. HABs can be found in both fresh and saltwater systems and usually occur when there is an overabundance of nutrients such as nitrogen and phosphorus, along with warm temperature and high light. HABs are potentially dangerous because they can produce hazardous toxins, which can harm wildlife, contaminate seafood, and lead to human health risks such as skin irritation, respiratory problems, and neurological disorders. As a result, early detection, monitoring, and control of HABs is paramount. In addition to their environmental significance, HABs can also have an economic impact, as they can lead to decreases in tourism and recreational activities.
