Sensors for Monitoring Harmful Algae, Cyanobacteria and Their Toxins

6 C HARGE Q UESTIONS A series of charge questions was posed to stimulate and guide discussion in the workshop, towards defining recommendations. Breakout Session A - What are the challenges associated with current HAB and toxin technology/detection? • Q1: What are the cost, usability and readiness levels for current methods? Table 1 outlines various usability metrics associated with currently available technologies.
