Which parameter is used to assess cyanobacteria during PARE analysis?

Explanation:
The key idea is that assessing cyanobacteria in PARE analysis relies on directly measuring the organisms themselves. Identifying which cyanobacteria are present and counting how many cells are in a given volume provides a concrete measure of bloom density and potential exposure risk. Temperature and pH influence growth but don’t quantify cyanobacteria, and turbidity only indicates how cloudy the water is, which can be caused by many substances and doesn’t specifically reflect cyanobacterial abundance. So, cyanobacteria ID and cell counts is the appropriate parameter for this assessment.
