What is air pollution?

• Addition of harmful substances to the atmosphere
  resulting in damage to the environment, human
  health and quality of life
• Can occur indoor or outdoor, in cities and across
  continents and even globally
• Air pollutants consist of gaseous pollutants,
  odors, suspended particle matter (dust, fumes,
  mist and smoke)

Some Types of Air Pollution

• Oxides of Nitrogen (NO NO2 NOX)
• Sources Power plants, cars, forest fires,
  trains, planes, volcanoes, industry, burning
• Sulfur Dioxide (SO2)
• Sources Burning of sulfur containing fuels,
  sulfuric acid production facilities
• Carbon Monoxide (CO)
• Sources cars, power plants, burning, industry

6
Some Types of Air Pollution

• Particulate Matter (PM2.5 and PM10)
• Sources Dust, power plants, diesel trucks,
  industry
• Lead (Pb)
• Sources smelting, lead fuels
• Ozone (O3)
• NOx Sunlight Ozone

Pinellas County

• Burn Garbage as only fuel
• All garbage in Pinellas Co. goes to the
  incinerator
• Burn 1150 tons of garbage per stack (3) per day
  capacity (2190 average per day)
• Generate 75 megawatts/hr
• Powers about 45, 000 households in Pinellas Co.
• Sell all generated electricity to Florida Power
• Pollutants Emitted
• SO2, NOx, Dioxin, Carbon Monoxide, Particulate
  Matter (measured via opacity), HCl, Lead,
  Mercury, Cadmium

Gandy South Air Monitoring Site

Gandy South Air Monitoring Site

• Kerstin Kenty has set up an air monitoring site
  located across from the existing Tampa Bay
  Estuary Program (TBEP)/Hills. Co. Gandy
  monitoring site.
• Some instrumentation used includes temperature
  and relative humidity probes and anemometer, a
  CO2 monitor and an Opsis UV-Differential Optical
  Absorption Spectrometer (DOAS).
• Pollutants measured include NO, NO2, SO2,
  benzene, toluene, m,p-xylene, and ozone.

Wet Scrubber Lab

Wet Scrubber Lab

• The wet scrubber is one of the most common
  pollution control devises used in industry.
• To become familiar with the process that the
  power plants use to eliminate pollution, we built
  a wet scrubber.
• The process begins when a polluted gas stream is
  brought into contact with a liquid so that the
  pollutants can be absorbed into the liquid.
• We saw this process at TECO Big Bend.

Electrostatic Precipitator Lab

• An Electrostatic Precipitator is another form of
  pollution control used in industry.
• We made our own much smaller electrostatic
  precipitator with a plastic tube, hairdryer, and
  some ground pepper.

23
Conclusion

• To conclude, air pollution is everywhere. It
  doesnt just come from industry, it comes from
  normal everyday activities, such as driving to
  and from work.
• It is vital that the government supports the EPA,
  by giving them more grants and funds so they are
  able to research the environmental dilemmas,
  especially air quality.
