Introduction
-
Basic characteristics of particulate matter
-
Particulate matter (PM) refers to solid and liquid colloidal particles
suspended in the air.
-
Particle size spectrum and definition of TSP, PM10, PM2.5.
-
Sources of particulate matter and their characteristic particle size and
chemical composition (Spengler and Wilson, 1996)
-
Indoor/outdoor air
-
Most studies focus on outdoor air, however we are typically spending most
of out life indoors
-
A few studies performed so far show how outdoor PM controls indoor PM,
but that there are also sources of indoor PM, such as cooking, cleaning,
and resuspension of PM by indoor activities (Long et al., 2000)
-
Health effects
-
Mechanisms and penetration of different size particles into the human body
-
The Health Effects Institute estimates that each year about 60,000 people
die prematurely from cardiopulmonary causes linked to particulate air pollution
(HEI, 2000).
-
There is also a increasing trend in occurrences of asthma cases, in particular
in NYC
-
Indoor/outdoor PM experiments in NYC
-
Summary of prior work performed on this topic in NYC
Thesis statement
-
I am planning to study the processes controlling indoor PM in my own apartment
at Barnard.
-
I suspect that indoor particle concentrations will be high and correlated
with outdoor PM and indoor activities because
-
the outdoor PM concentrations are high in NYC (Amsterdam Ave.) and windows
in my fairly old (off campus) apartment are leaky,
-
I do a lot of cooking,
-
I allow my friends to smoke in my apartment.
Approach/methods
-
The indoor/outdoor gas exchange rate will be determined by adding a small
quantity of SF6 into the air and subsequent monitoring of the
concentration drop-off due to exchange with outside air with a gas chromatograph.
-
An optical particle monitoring devices will be used that measures indoor
and outdoor PM concentrations and particle size distribution.
-
Careful records will be kept on activities inside the apartment, such as
walking, cooking, smoking etc.
-
The experiment will run for one week.
-
The resulting PM concentration time series will be modeled with a simple
1-box spreadsheet model.
Preliminary results and discussion
-
The experiment will be conducted in mid November.
-
I expect to be able to include raw data in the thesis proposal.
-
My research mentor and I have tested the PM equipment using ambient atmospheric
air outside of the LDEO Marine Biology/Seismology laboratory. We saw major
spikes in concentrations when holding a burning piece of paper near
the intake of the instrument.
-
The SF6 gas chromatograph was also tested but did not show a
linear response when exposed to SF6 standards of know concentration
(see enclosed graph). We do not currently know what the problem might be.
My mentor hopes to be able to fix the problem during the next week.

Implications of research
-
If successful the experiment will shed light on the typical exposure of
a Barnard student to indoor PM.
-
The measured exposure can be translated into a an estimated additional
health risk.
-
If appropriate, recommendations will be made regarding indoor PM reduction
strategies, such as elimination of PM sources, frequent venting of the
apartment, or purchase of air filters.
