Bom dia, Ramiro,
It is not Algae, but NIST at least has a very low noncertified value for Ag in tomato leaves:
Não é algas, mas NIST pelo menos tem um valor muito baixo (não certificado) para Ag em folhas de tomate.

Thanks Daniel and Johan for the feedbacks, they are much
we are conducting investigation in the Ag transference
(bulk and nanoparticled) in a simulated freshwater food
chain and we are using Pseudokirchneriella subcapitata
(formerly known as Selenastrum capricornutum) as producer.
That is why I was so surprised by the relative absence of
CRMs for Ag, especially since the nanoparticles are kind
of a hot topic at the moment.
