2
With Educators
  • Kerstin Lesley Kenty
  • Melissa Evans

3
Overview
  • Definition, sources and effects of air pollution
  • Facility Tours
  • Lab Experience
  • Monitoring Site
  • Conclusion

4
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

Amounts of Air Pollution

How does air pollution affect people?
  • Contributes to
  • Asthma
  • Emphysema
  • Mortality
  • Cancer
  • Populations most at risk
  • Elderly
  • Very young children
  • Outdoor exercisers
  • People with existing respiratory problems

Facility Tour Pinellas County Resource Recovery

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

Tampa Electric (TECO) Big Bend
  • Burn Pulverized Coal
  • TECO owned mine in Ky, shipped down Mississippi
  • Generate 1600 Megawatts/hr
  • 500,000 households
  • 2/3 of all energy for Hillsborough County, Pasco
    County and Lakeland
  • Pollutants Emitted
  • SO2, NOx, CO, CO2, Particulate Matter, Mercury

Gandy South Air Monitoring Site
17
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
20
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.

22
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.

We would like to thank Kerstin and Melissa for
everything they did for us.

We would like to thank Mrs. Kent for her time in
making this an enjoyable experience.
