ENSC 1410 Lab 8: Indoor Air Pollution Scavenger Hunt As you already know, indoor air pollution poses a greater threat than outdoor air pollution because it is harder to escape. People trapped inside day after day in offices or homes keep breathing the same pollutants, plus many of the modern chemicals and materials we use can be toxic. Many air exchange systems, especially in workplaces, may not be sufficient in removing toxins. Here is your assignment: 1. https://www.epa.gov/indoor-air-quality-iaq/introduction-indoor-air-quality Use this site to familiarize yourself with Indoor Air Pollution. Look at the sources, effects and improvements that can be made. 2. 5 levels of indoor air pollution https://www.youtube.com/watch?v=xpaEWQU_bPc&feature=youtu.be and What is sick building syndrome? https://www.youtube.com/watch?v=mmho_iKsfQo&feature=youtu.be 3. Since you are confined to your home, this is the perfect opportunity to investigate possible sources of indoor air pollution you are exposed to. You will do a scavenger hunt, locating at least 6 different sources of indoor air pollution in your own home. You have two options: • You can create a movie narrated by you that tours your house. You must include a visual of the source and discuss the toxic chemical that you are exposed to, the human health impacts of that chemical or source, and alternatives or ways to remediate these toxic exposures. OR • A PowerPoint that I can view, including a picture of the source in your home, identification of the toxic chemical, the human health impacts of that source or chemical, and alternatives or ways to remediate these toxic exposures. You may need to do some research to give quality, detailed, information. Be as specific and thorough as possible. ** IF you use any pictures or quote any information that is not your own, make sure the cite this information either on that page or in a collection at the end. Source Chemical Impact Remediation or Alternative EXAMPLE: Woodstove (Incomplete combustion of wood) Carbon Monoxide Dizziness, heart attack, asthma, asphyxiation and death Gas stove instead of wood, catalytic converter on woodstove, better ventilation in house Use this table to organize your movie/PowerPoint. I will grade you on each of these categories, plus your creativity. Have fun with this lab!

INDOOR AIR QUALITY
INTRODUCTION:
• Indoor Air Quality is the air quality (IAQ) within and
around buildings and structures.

• IAQ is known to affect the health, comfort, and well
being of building occupants.
• Poor indoor air quality has been linked to sick building
syndrome, reduced productivity and, impaired learning
in schools.
• IAQ is now more significant than ever because more
people are confined to their homes in an attempt to
quarantine themselves to avoid contracting The Corona
Virus, which is a pandemic currently plaguing the
world.


What are the Causes of Poor IAQ ?
• Poor Ventilation.
• Prevents toxins, allergens, and other pollutants that have become stuck in your house from
escaping to the environment.
• Ventilation ensures a circulation of fresh air from outside to the inside of the houses, flushing out
the stale air.

• Household Cleaning Supplies
• Many of the chemicals used within them contribute to a variety of health problems, including
headaches, asthma, and many respiratory illnesses.
• The moment you spray them in your house, you start inhaling them.



What are the Causes of Poor IAQ ?

• Mold and Mildew
• If your home has excessive moisture in the air, mold will likely be growing
somewhere in your house.

• As time passes, the mold grows, and eventually, more spores are put in the
air you inhale.
• These microscopic spores can lead to potential illnesses, which is why it’s
paramount to make sure the humidity levels in your house are not too high.
• If they are high, it is recommended that you get a dehumidifier for you
home

What are the Causes of Poor IAQ ?
• Cigarette Smoke:
• Limiting lighting a cigarette inside the house goes a long way in improving the air
quality in the home.
• With an estimated 200 poisons contained within them, cigarettes are another common
cause of poor air quality.
• Cigarettes affect both active smokers and passive smokers.
• Prolonged use of cigarettes results in adverse effects on both smokers, such as cancer,
impotence, addiction, and indirect consequences include bankruptcy, lower productivity
of an individual since they are addicts, and largely depend on cigarettes t function.
• Environmental tobacco smoke contributes to increased levels of VOCs, other toxic
compounds, and respirable particulate matter.

What are the Causes of Poor IAQ ?
• Formaldehyde
• Commonly found in carpets, plywood paneling, upholstery, and many other consumer products,
formaldehyde is a dangerous chemical that contributes to poor air quality.

• Polyurethane:
• Commonly sprayed on wood furniture and floors, polyurethane helps seal them from water damage and
improve their look.
• However, it’s also added to the inside of the mattresses.

• Polybrominated biphenyl (PBB) and Polychlorinated biphenyl(PCB):
• These chemicals are commonly found in a wide variety of consumer products that contain plastic,
including furniture, televisions, computer monitors, and anything with plastic foam. ...
