Abstract
Bismuth
(Bi)
is
a
particular
element
with
many
distinctive
properties
such
as
low
toxicity
or
nontoxicity,
high
specific
gravity,
photoluminescence,
photoelectronic
and
photovoltaic
effects,
strong
oxidation
ability,
water
insolubility,
etc.
These
help
to
boost
various
applications
of
Bi.
The
recent
decades
have
witnessed
dramatic
increase

Algae
supplements
are
widely
recognized
for
their
nutritional
benefits
and
commonly
marketed
as
natural
health
products.
However,
concerns
regarding
contamination
with
cyanobacterial
toxins
have
been
raised.
Moreover,
there
is
very
little
data
the
potential
of

these
toxins.
In
this
study,
we
employed
a
validated
solid-phase
extraction
ultra-high-performance
liquid
chromatography-tandem
mass
spectrometry
(SPE-UHPLC-MS/MS)
method
to
analyze
available
in
China.
Therefore,
study

via
UHPLC-MS/MS.
Method

was
conducted
four

matrices
(capsule,
liquid,

Analysis
nineteen
commercial

revealed
presence
MCs:
microcystin-LF
(MC-LF),
microcystin-LR
(MC-LR),
microcystin-LA
(MC-LA),
microcystin-YR
(MC-YR).
Furthermore,
seven
were
found

These
