Widespread, low concentration microcystin detection in a subtropical Louisiana estuary.

Spatiotemporal patterns and drivers of hepatotoxic microcystins (MC) were investigated in the Atchafalaya-Vermilion Bay System (AVBS), a subtropical, river-dominated estuary in Louisiana. Along with environmental data, monthly particulate MC (pMC) samples were examined over a two-year period (2016-2018), and biweekly pMC and dissolved MC (dMC) samples were examined over a five-month period in 2020. Solid phase adsorption toxin tracking (SPATT) samplers used to quantify time-integrated dMC concentrations were also deployed in 2020. Low, but detectable concentrations of pMC (≤0.033 μg L
