Volcanic smog is a type of smog that forms when gases and particles are released from an erupting volcano and mix with sunlight, oxygen and.
The gray smog of older industrial cities like london and new york derives from the massive combustion of coal and fuel oil in or near the city, releasing tons of ashes, soot, and sulfur compounds into the air. The smog results in mortifying impacts on the environment by killing innumerable animal species and green life, and it takes time to adapt to breathing and surviving in such toxic environments. The chemicals like the hydrocarbons, nitrogen oxide reacts with the sunlight in atmosphere which produces smog.
