Llack carbon is a common air pollutant found in many urban areas around the world.

Black carbon primarily comes from the incomplete combustion of fossil fuels, biomass, and biofuels. Sources of black carbon emissions can include transportation (e.g., cars, trucks, buses), industrial processes, and residential cooking and heating (e.g., wood-burning stoves).

In urban areas, the most significant sources of black carbon emissions are typically transportation and residential heating. In developing countries, biomass burning for cooking and heating can also be a significant source of black carbon emissions.

It is important to note that black carbon is not only a local pollutant but also a global one. It can travel long distances through the atmosphere and contribute to climate change by absorbing sunlight and warming the atmosphere.
