Lim-Tex® Research Calculator
cyanoCastingTM :Estimates of Cyanotoxin Concentrations and Excess Biomass
Using field data from over 150 sites spread across the region (New Hampshire, New York and Massachusetts) since 2015, we’ve developed and verified the Calculator for your use. We’re always looking for ways to update our database, either by adding genus and/or species to account for biogeographical differences, including additional toxins and investigating new metrics. To date, we are still coming to the conclusion that there are correlations between cyanobacterial biomass (measured as phycocyanin) and cyanotoxins.
Disclaimer: This is a first order screening tool intended to be used with Lim-Tex products and procedures as described in the Quality Assurance Project Plans (QAPP) to assist with real-time evaluation of cyanobacteria. QAPPs found below. The cyanotoxin concentrations reported herein as “total microcystins” based on ELISA analysis. This calculator does not include other cyanotoxin concentrations (e.g. cylindrospermopsin or anatoxin-a).

* Interpretation of net growth rates: <0.02 = Low, 0.02 – 0.07 = Medium, >0.07 = High. See “Research” for more information on cyanobacterial net growth rates.
