In some cases a chemical is basically embodied but there are some losses in processing. Losses in chemical manufacturing per se are included here. In some cases virtually all of the material is actually dissipated. Also included are wood preservatives and chromium salts embodied in leather. However, copper, chromium, and arsenic are used as wood preservatives and and dispersed only if the wood is later burned or incinerated.
Uses are dissipative but heavy metals are largely immobilized by soil.
Arsenic and mercury are exceptions because of their volatility. Non-agricultural biocides are the same compounds, used in industrial, commercial, or residential applications. Loss rates are high in some cases. Most are dissipated to the environment via waste water. Silver and mercury dental fillings are likely to be buried with the dead body.
