It depends on the type of the tests that you will carried on. For example, if you want to determine the traces of these heavy metals by HPLC, you can do the homogenization in isotonic solution (0.9% NaCl) then store them in refrigerator

Mohamed Shaalan

You could use a mixture of Perchloric acid and Nitric acid with heating then measure using atomic absorption spectroscopy or ICP/MS
