What are the effects of smog on humans? - ANSWER Irritates eyes and throat,
causes respiratory problems
What are the effects of smog on ecosystems? - ANSWER Damages crops and
reduces yield
How can smog be reduced? - ANSWER Reduce emissions, use public
transportation, cleaner energy
What is a thermal inversion? - ANSWER Warm air traps cooler, dense air
below
What is the effect of thermal inversion? - ANSWER Pollution is trapped and
builds up
What are natural sources of particulates? - ANSWER Volcanoes, fires, dust,
pollen
,What are indoor particulates? - ANSWER Dust, smoke, mold, asbestos
What are indoor combustion pollutants? - ANSWER CO, NOx, SO2,
particulates, tobacco smoke
What is radon? - ANSWER Radioactive gas from uranium decay
How does radon enter homes? - ANSWER Through cracks in the foundation or
groundwater
Why is radon dangerous? - ANSWER Causes lung cancer
What is smog? - ANSWER Smog is a type of air pollution that combines smoke
and fog, typically resulting from industrial emissions and vehicle exhaust.
What are common causes of smog? - ANSWER Common causes of smog
include vehicle emissions, industrial pollutants, burning of fossil fuels, and natural
phenomena like wildfires.
What is photochemical smog? - ANSWER Photochemical smog is a type of air
pollution formed when sunlight reacts with pollutants such as volatile organic
compounds (VOCs) and nitrogen oxides, leading to the formation of ozone and
other harmful compounds.
What is industrial smog? - ANSWER Industrial smog is a type of air pollution
that results from the burning of fossil fuels, particularly coal, which releases sulfur
dioxide and particulate matter into the atmosphere.
, What are the health effects of smog? - ANSWER Health effects of smog can
include respiratory problems, eye irritation, reduced lung function, and increased
risk of heart disease and asthma.
What are the environmental impacts of smog? - ANSWER Environmental
impacts of smog include damage to crops, forests, and bodies of water, as well as
contributing to climate change and harming wildlife.
What are common mitigation strategies for smog? - ANSWER Common
mitigation strategies for smog include reducing vehicle emissions, implementing
stricter industrial regulations, promoting public transportation, and increasing
green spaces.
How do vehicle emissions contribute to smog? - ANSWER Vehicle emissions
release nitrogen oxides and volatile organic compounds, which react in sunlight to
form ozone, a key component of photochemical smog.
What role do industrial pollutants play in smog formation? -
ANSWER Industrial pollutants, such as sulfur dioxide and particulate matter,
contribute to both industrial smog and the formation of secondary pollutants that
exacerbate air quality issues.
What is the difference between photochemical and industrial smog? -
ANSWER Photochemical smog is formed by chemical reactions in the presence
of sunlight, while industrial smog is primarily caused by the combustion of fossil
fuels and is more prevalent in cooler, damp climates.
, What are some long-term health effects of exposure to smog? -
ANSWER Long-term exposure to smog can lead to chronic respiratory diseases,
cardiovascular problems, and increased mortality rates.
How does smog affect visibility? - ANSWER Smog reduces visibility by
scattering and absorbing light, making it difficult to see through polluted air.
What is the role of ozone in smog? - ANSWER Ozone, a major component of
photochemical smog, is harmful at ground level and can cause respiratory issues
and other health problems.
What are volatile organic compounds (VOCs)? - ANSWER Volatile organic
compounds (VOCs) are organic chemicals that can evaporate into the air and
contribute to the formation of smog, particularly photochemical smog.
What is the impact of smog on agriculture? - ANSWER Smog can damage
crops by reducing photosynthesis, harming plant health, and leading to lower
agricultural yields.
What are particulate matter (PM) and its relation to smog? -
ANSWER Particulate matter (PM) consists of tiny particles in the air that can
penetrate the respiratory system, contributing to both industrial and photochemical
smog.
The fan must be used when ambient temperature reaches how many degrees ? -
ANSWER 72 degrees and above
