We have embarked on studies of heavy metals associated with microalgae and
filamentous greens in urban streams. We are looking for a source of reference
algal material which has been certified to contain specific amounts of metals
such as iron, cadmium, lead, tin, cobalt, nickel, copper, zinc. There are
diverse plant and animal tissues available (e.g. "NIST", "CASS" standards), but
I would like to use something more relevant to freshwater algae for
"ground-truthing" our methods development. I would have thought, for instance,
that reference contaminated Selenastrum would exist, but we can't find a
Can anyone guide us to a source of reference, metal-contaminated algal material?
Thanks for your time.
