Anatoxin-a (ATX) accumulated each month from SPATT monitoring locations in 2013 and 2014.
, 2018 Red points indicate sites where cyanotoxins were no accumulated anatoxin-a was detected (ND) on SPATT samplers. The diameter of the black points categorize the range of cyanotoxins accumulated on the SPATT samplers for a given month.

Rapid Immunochemical Methods for Anatoxin‑a Monitoring in Environmental Water Samples
, 2022 Algal blooms that contaminate freshwater resources with cyanotoxins constitute, nowadays, a global concern. To deal with this problem, a variety of analytical methods, including immunochemical assays, are available for the main algal toxins, for example,
