Air Pollution:

Has many effects on public health

and the environment.

Comes in different forms and from many sources.

Ozone and Particulate matterare two types ofAir

Pollution that affect Maine.


7/22

What is Ozone?

An odorless, colorless gas

composed of three oxygen

atoms. Ozone in the upper atmosphere protects usfrom the suns harmful ultraviolet rays.

At ground-level in the air we breathe, ozone(smog) poses serious risks to human health.


8/22

Ozone is created by a chemical reaction:

Where Does Ozone Come From?

O3+ =

VOC + NOx + Heat + Sunlight = Ozone

VOC (

Volati

le Organic Compounds) and NOx(Nitrogen Oxides) come from motor vehicles,

power plants, industrial facilities, and other

sources.


9/22

Why is Ozone Bad to Breathe?

The average adult breathes enough air to fillover 3,000 balloons each day. Children

breathe even more!

Ozone can irritate lungs and airways, and

cause inflammation much like a sunburn on

yourlungs.

Ozone can aggravate respiratory illnesses like

asthma.

Health Effects of Exposureto Ozone

Coughing

Nose and throat irritation

Chest pain

Reduced lung function

Increased susceptibility to respiratory illnesses

Aggravation of asthma

What is Particulate Matter?

particles of different substances suspended in

the air

in the form of solid particles and liquid droplets

particles vary widely in size


16/22

Fine particles come from a variety of sources: diesel trucks and buses

construction equipment

power plants

woodstoves

wildfires

Where does Pm come from?

Also, Chemical reactions in the atmosphere

can transform gases into fine particles.


17/22

Fine particles are only a fraction

of the size of a human hair.

How Fine is Fine?

Fine Particles(2.5Qm)

Cross section of a human hair (magnified to 60Qm)

Coarse Particles(10Qm)


18/22

Whyare Fine Particles

Bad to Breathe? Scientific studies have linked fine particles with a series of

significant health problems.

Fine particles easily reach the deepest parts of the lungs.

Particulate matter causes 15,000 premature deaths every

year in the US.

Fine particles from Diesel exhaust can cause lung cancer.


19/22

Health Effects of Exposure

to Fine Particles Premature death

Aggravated asthma

Respiratory-related emergency room visits andhospital admissions

Acute respiratory symptoms

Chronic bronchitis

Decreased lung function (shortness of breath)

Peo le with existin heart and lun disease as


20/22

Reduce vehicl

e emissions:

Drive less

Keep cars well maintained and tires properly inflated

Turn off the engine when your vehicle is not in motion

Purchase low-emitting and fuel efficient vehicles

Share a ride, take public transportation bike, or walk

Cut your grass after 6 p.m.

Refuel your car after 6 p.m.

Combine errands into one trip

What Can You Do?


21/22

What Can You Do?

Conserve electricity:

do not over-cool or over-heat buildings

turn offlights and appliances when not in

use

Purchase electronics/appliances with energystarlabelsTo protect your health, avoid strenuous outdoor activities

when ozone levels are high
