What is your Air Quality Index IQ?

(a)   contribute a lot to air pollution problems.

Answer explanation

Cars.

The automobile industry has made some improvements in equipment in cars that helps reduce pollution, and individual cars and buses release fewer pollutants into the air today than before. However, more people are driving today than ever, and that adds up to a lot of pollution.

When air is polluted, you can always see and smell it.

• True

• False

Answer explanation

False.

Some pollutants are odorless and colorless (such as ozone).

Air pollution is only a problem in big cities.

• True

• False

Answer explanation

False.

Everyone is affected by air pollution. The air we breathe does not usually stay in the same place, hovering over us, it moves. Wind carries pollution to us from hundreds of miles away. Also, the pollution that we produce, no matter how small an amount it may seem, can be significant when combined with everyone else’s “small amounts.”

Respiratory diseases in children, including asthma, pneumonia and

bronchitis are linked to breathing dirty air.

• True

• False

Answer explanation

True.

Children's immune systems are still developing and their lungs are growing, which makes them very susceptible to harm from air pollution. It can increase children's risk of asthma and stunt their lung

growth. Globally, air pollution has been linked to deadly diseases like pneumonia.

Global warming is mainly caused due to the excess amount of (a)   gas in the atmosphere?

What is the environmental significance of measuring noise intensity?

• It is not significant, noise doesn't pollute air

• It can impact marine animals, like dolphins and whales, since they use echolocation for orientation

• While it is true that noise pollution occurs in certain workplaces, it has no environmental significance and concerns only humans.

Answer explanation

It can impact marine animals, like dolphins and whales, since they use echolocation for orientation.

It is called noise pollution; unwanted or excessives sound that can have bad impact on human health, wildlife, and environmental quality.

It is commonly generated inside many industrial facilities and some other workplaces, but it also comes from highway, railway, and airplane traffic and from outdoor construction activities.

To humans (at certain levels and durations of exposure), it can cause physical damage to the eardrum, resulting in temporary or permanent hearing loss.

It impacts wildlife too, as a wide range of animals (marine life, insects, frogs, bats, birds...) rely on sound for a variety of reasons. Noise pollution can interfere with an animal’s ability to attract a mate, communicate, navigate, find food, or avoid predators and thus can even be a threat to vulnerable organisms
