Galaxies, along with their underlying dark matter halos, constitute the building blocks of the universe. Of all the fundamental forces, gravity is the dominant one that drives the evolution of structures from small density seeds to the galaxies we see today. The interactions among myriads of stars, or dark matter particles, in a ... |  |  Air Pollution: Sources, Impacts and Controls
The problem of air pollution has become a global issue, driven by rapid economic growth, industrialization, and urbanization. Pollutants directly emitted into the atmosphere include nitrogen oxides, carbon monoxide, sulphur oxides, particulate matter (PM), volatile organic compounds, carbonaceous particles, dust, and sea-salt.
