BSA Environmental Services provides exceptional cyanobacterial toxin analyses
to effectively monitor drinking and recreational water quality for government
and commercial clients. Our reliable analytical results may be used when making
timely management decisions.

Cyanobacteria or blue-green algae, which are typically dominant in eutrophic
waters (nutrient-rich), can produce toxins. Presence of microcystin and other
cyanotoxins (commonly produced by Microcystis spp. and Cylindrospermopsis spp.)
in reservoirs, lakes and rivers represent a potential significant risk to
wildlife and public health. Reported health problems attributed to drinking
water contaminated with cyanotoxins have increased in recent years.

Methods
Upon receipt, samples first undergo a freeze-thaw cycle followed by
ultra-sonication. This process ensures complete cell lysis to provide an
accurate representation of toxin presence.
BSA uses Enzyme-Linked Immunosorbent Assay (ELISA) testing of freshwater
samples to produce sensitive, specific, and rapid results. ELISA kits (provided
by Abraxis) detect cyanotoxin values as low as 0.15 ppb.
We currently perform analyses for:
- Microcystins / Nodularins
- Cylindrospermopsin
- Saxitoxin
