Summary
Cyanobacterial harmful algal blooms release microcystins (MCs), posing health risks. This review details analytical methods for detecting MCs in water, crucial for public health and environmental safety.
Area of Science:
- Environmental Science
- Toxicology
- Analytical Chemistry
Background:
- Cyanobacterial harmful algal blooms (CyanoHABs) produce microcystins (MCs), potent hepatotoxins affecting humans and animals.
- Over 270 microcystin variants exist, complicating detection and risk assessment.
- Effective management of MCs requires sensitive, rapid, and reliable detection methods.
Purpose of the Study:
- To review and compare major analytical methods for microcystin detection.
- To assess the current state, novel developments, and limitations of these methods.
- To provide recommendations for future research and method improvement.
Main Methods:
- Biological methods (e.g., mouse bioassay).
- Biochemical assays (e.g., protein phosphatase inhibition assay, ELISA).
- Chemical techniques (HPLC, LC-MS, HPCE, GC) and emerging biosensors.
Main Results:
- The review covers a spectrum of detection techniques, from traditional to novel.
- Each method's merits, limitations, and current applications are discussed.
- Comparative analysis highlights the strengths and weaknesses of different approaches.
Conclusions:
- No single method is universally superior; method selection depends on specific needs.
- Advancements in biosensors offer promising alternatives for rapid and sensitive detection.
- Further research is needed to refine existing methods and develop new ones for comprehensive MC monitoring.
