Harmful algal blooms (HABs) are increasing, causing seafood illnesses and harming resources. New rapid analytical methods, including molecular probes and advanced chromatography, are being developed for early detection of toxins and organisms to protect public health.

Area of Science:

  • Environmental Science
  • Toxicology
  • Analytical Chemistry

Background:

  • Harmful algal blooms (HABs) are increasing globally in frequency and intensity.
  • This rise leads to more seafood-borne illnesses and negative impacts on natural resources.
  • Public health agencies require robust monitoring programs to address these challenges.

Purpose of the Study:

  • To review innovative analytical techniques for rapid and reliable detection of HAB-causing organisms and their toxins.
  • To highlight advancements in methods for protecting public health, aquaculture, and natural resources.
  • To discuss new approaches for understanding toxin behavior in microenvironments.

Main Methods:

  • Modifications to conventional chromatography and mass spectrometry have enhanced sensitivity and selectivity for phycotoxins.
