You can browse the Internet and find here and there some hints and data but for background values of the entire PSE in a great variety of environments I would recommend: The Handbook of Geochemistry edited by K. H. Wedepohl which is not a single thick volume but a loose-leaf collection of different volumes dependant on what you are in search of.
You can review the geochemistry treatise https://www.sciencedirect.com/book/9780080983004/treatise-on-geochemistry
Where you can see tabulated data with the elements, matrix and references. Usually when we do not have a background data we use the concentrations of the earth's crust.
You must pay attention if the fractions are comparable, that is, type of attack of the sample (total or leached).
