Write an introduction which includes 6-10 sentences of background on the sources of indoor air pollution and an explanation of the harm of indoor pollution. Please refer to the image that I took from the survey and my notes. Please write this lab write-up based off of the information and the observations of those pollutants as well as the many that are listed below. Plus 1-2 sentences on what you plan to accomplish in this lab (try to avoid using the words I and we) and how you will accomplish your goals. I have attached the full instructions to this lab write-up, as well as the info that you are not limited to but may include in addition to the many listed down below, and finally an example of a past lab if you have any confusion. Finally, if you have any questions on anything please don’t be afraid to ask, as well as any clarifications like when you can’t read my handwriting.
You do not need to include the materials and procedure sections in this lab write up.
With your instructor, examine the classroom and the school and record on the data table any sources of indoor pollution. These may include, but not limited to the following:
· Drinking fountains release chloroform off-gassing chlorine treated water
· Floor mats at the entryways have particles of dust, fungal spores, lead, arsenic from soil, herbicides and/or fungicides – all of which are taken up into the air ventilation system.
· The air ventilation system takes up and traps the particulate contaminates, giving the fungal and bacterial spores a substrate (support or base) upon which to multiply.
· A cleaning closet or any surface that has just been cleaned may have chemicals such as ammonia, trichloroethane, paradichlorobenzene and VOC’s.
· Air fresheners in bathrooms contain a VOC called paradichlorobenzene and other VOC’s.
· Photocopy machines release ozone, chloroform, formaldehyde and other chemicals.
· Dry cleaned clothing contains tetrachloroethylene
· New carpet and furniture off-gasses formaldehyde, chloroform, fiberglass and styrene.
· Cigarettes produce carbon monoxide, arsenic, benzo-pyrene, cadmium, VOC’s and particulate matter.
· Cracks in the foundation can allow radon gas to enter the building.
· Ceiling times, floor tiles and pipe insulation may have asbestos, fiberglass and vinyl chloride.
· Combustion sources may emit carbon monoxide, benzene/gasoline, sulfur oxides and nitrogen oxides.
· Pesticides or fungicides are sources of cadmium, mercury and VOC’s.
· Paints, stains and building putty may contain lead, methylene chloride, VOC’s, benzene or toluene.
· Areas with leaks often lead to mold.
Conclusion – based on your data, write 6-10 sentences on the indoor air quality at a High School. What analytical tests would you run to be sure?
