combustionderived

Combustionderived is a term used in some scientific literatures to categorize substances and materials that originate from combustion processes. It encompasses gases, vapors, particulates, and later-stage reaction products produced when fuels, biomass, or wastes burn. The term is not universally standardized but is used to distinguish combustion-related constituents from other chemical sources.

Common constituents include carbon dioxide and monoxide, nitrogen oxides, sulfur oxides, volatile organic compounds, polycyclic aromatic hydrocarbons, soot and black carbon, and various metals and ash constituents. Particulate matter from combustion (PM2.5 and PM10) is often a major focus because of health and climate relevance. The exact composition depends on fuel type, combustion temperature, oxygen availability, and emission controls.

Sources include road and rail transportation, power generation, industrial furnaces, residential heating, waste incineration, and natural fires such as wildfires. Combustionderived emissions contribute to ambient air pollution and can undergo atmospheric transformations, forming secondary pollutants such as ozone and secondary organic aerosols.

Impacts include adverse health effects from inhaled fine particles and toxic compounds, ecological effects, and climate implications through greenhouse gases and light-absorbing carbon such as black carbon. Control strategies target emission reductions and cleaner technologies.

In research and policy, combustionderived substances are studied with air quality monitoring, emission inventories, and modeling. The term helps researchers discuss a broad class of combustion-related products without committing to a single chemical taxonomy.
