According to protocol 3001 from SIKB soil samples need to be conserved via a specific container and method.
Conserving method
For all samples below the following holds. The samples need to be conserved at 1-5 oC, airtight and in a dark container.
In the following table all possible contaminations are mentioned and a conserving period and container prescription are mentioned. The legend for the table can be found under the table.
