"On the Source of Brown Carbon"

Between heaven and earth, everything has its source, and brown carbon is no exception. Exploring the source of brown carbon involves many things and needs to be studied in detail.

The source of brown carbon may originate from various fireworks. Human fireworks, cooking and heating, burning charcoal, during which there may be a source of brown carbon. When the charcoal is burned, the fireworks rise, and the material changes in high temperature, or the quality of brown carbon.

Or it originates from various industrial trips. Workshop smelting, kiln firing, chemical operation, complex changes in materials, and many reactions are intertwined, which may be the origin of brown carbon. The chemical changes are complicated, the material is mixed and transformed, and brown carbon may be generated from it.

Mountain forest wilderness, vegetation decay, or the source of brown carbon. Grass and trees wither, decay over time, microorganisms participate, chemical processes start, or give rise to the formation of brown carbon. This natural change, quietly made, adds a source of brown carbon in a silent place.

Rivers, lakes and seas, the things carried by the water flow, after precipitation and decomposition, may also be related to the source of brown carbon. Various things in the water, or the substances that can cause brown carbon formation, are hidden in the circulation of water and environmental changes.

To understand the source of brown carbon, it is necessary to widely investigate all things in the world and study the principles of material changes in order to gain insight into its source, use it for subsequent events, understand its advantages and disadvantages, and seek good policies.
