What is the main cause of photochemical smog?
Photochemical smog is produced
when sunlight reacts with nitrogen oxides and at least one volatile organic compound (VOC) in the atmosphere
. Nitrogen oxides come from car exhaust, coal power plants, and factory emissions. … When sunlight hits these chemicals, they form airborne particles and ground-level ozone—or smog.
Which is the major photochemical smog?
Ground-level ozone
constitutes one of the major components of photochemical smog, so called because of the photochemical reaction of air pollutants such as nitrogen oxides (NOx) and volatile organic compounds (VOCs) with ultraviolet light (sunlight); thus, the O

levels vary strongly with season and the highest levels …
What are the two harmful effects of smog?
Smog can cause or aggravate health problems such as
asthma, emphysema, chronic bronchitis
and other respiratory problems as well as eye irritation and reduced resistance to colds and lung infections. The ozone in smog also inhibits plant growth and can cause widespread damage to crops and forests.

water is able to dissolve more substances than any other liquid on earth
. … It’s also why water is so easily polluted. Toxic substances from farms, towns, and factories readily dissolve into and mix with it, causing water pollution.
How are plants affected by smog?
Ozone and peroxyacetyl nitrate
that travel close to the ground as a result of smog can have damaging effects on plants, resulting in the discoloration and damage to plants. This reduces the amount of photosynthesis that these plants can engage in, according to the University of California.
