Question

How does phosphorus cycle without a gaseous component?

Answer 1

But particulate matter is important

Explanation:

You can read the following article to get an idea.

"Combustion of coal is one possible source of airborne P-bearing compounds, or `PM_10` as they are particulate matter ⩽10.0 μm. Recently, the environmental impact of the coal combustion process has become more critical due to: (1) the use of high calcium-containing coals (a portion of calcium in the form of apatite), and the adoption of much severe conditions, e.g., high temperature and oxygen enrichment in the furnace; (2) substitution of a portion of coal by the biomass, such as sewage sludge (which is rich in phosphorus) for the `CO_2` abatement."
