Dear colleagues,
One of the solutions for wet sieving of clayey samples is the addition
of hydrogen peroxide, which makes the clay desintegrate. I am
considering using this for a set of Dutch samples, in which the
preservation of the seeds is of great importance. Does anyone
know references to studies that deal with the effects of hydrogen
peroxide on botanical macroremains? If possible not only concerning
the present or absence of particular species in a comparison of
treated and untreated samples, but also on the corrosion observed
in individual seeds? The effects could be both positive and negative,
as H2O2 facilitates sieving, which might cause less harm to the
seeds during sieving, but H2O2 may also influence the seeds by
corroding them...
Many thanks in advance for your reactions,
oTTo
