Geochemical factors control trace element distribution across particle size fractions

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that geochemical factors control trace element distribution across particle size fractions?

Yes. Geochemical and physicochemical studies confirm that trace element and heavy metal distributions vary systematically across different particle size fractions in environmental matrices such as sediments and composts.

The analysis

The retrieved papers include multiple studies examining trace element distribution across various particle size fractions in soils, sediments, and municipal solid waste composts. Papers [6], [10], and [11] all explicitly demonstrate that trace elements and heavy metals are concentrated differently across size fractions due to geochemical and physicochemical factors (such as association with iron-bearing particles or specific surface areas). No papers refute the claim.
