There should be no rock fragments in biological material, as will be compared to concentrations of these metals within the cells to the concentration of metals in the water and the substrate.

Most of the algae can be removed from with the help of metal sulphate e,g.,Copper sulphate.
further anaysed as per standard method e.g. AAS/Titrimetric/Gravimetric/Spectrophotometric ,

A method used to determine biomass of attached algae is to remove them with a toothbrush. I dont know how much damage this does to the cells, but it least the method does not involve a metal.
