Answer 2

The smoke released from various sources may get mixed with dust particles and small drops of fog to produce what is called Smog.
Smog is harmful to plants and, if inhaled, may caused asthama and allergies in humans.
Smog is a Secondary pollutant...
Smog is harmful to both the respiratory (lungs) and cardiovascular (heart) systems. It aggravates heart problems, bronchitis, asthma, and other lung problems. Smog reduces lung function even in healthy people. Even at low levels, ground level ozone and fine particulate matter are harmful. There are no "safe" levels of smog.
