More on Smog - technical
Overview
Terminology:
- Several abbreviations are used that can be confusing – Here are some of the terms used and what we believe (based on our research today) they mean:
- AQI = Air Quality Index (calidad del aire): this number arises from an analysis that looks at both particulate matter and ozone content; here is a brief explanation.
- PM10 and PM2.5- Particulate Matter – of the inhalable variety has a range of sizes. PM10 refers to the largest that are inhalable (10 microns across) and PM2.5 refers to the most dangerous PM as it is only 2.5 microns wide (very small). The annual geometric mean of particulate matter is called the ug/m3.
- O3 and PPB – O3 refers to ground level ozone and PPB refers to the annual mean of ozone.
Advisories and Warnings using AQI Different Indices are difficult to compare as they refer to different standards. The U.S. AQI is a composite index using ozone, particulate matter and many other pollutants. The EPA has a good explanation of their AQI composite index at http://airnow.gov/index.cfm?action=static.aqi. This page also shows the chart used by the EPA.
In Chile
How do you find out the current air quality according to Chilean authorities? You can see their reporting here. If you are interested in the history of smog in Santiago, go to statistics on air quality. Their Chart is based on a rating figure called the ICAP, explained below. This index seems to be based only on particulate matter. Chilean authorities gauge the ozone levels separately. The Chilean Advisory Chart looks like this.
Their definitions used in defining their ICAP (Indice de Calidad del Aire Particulado):
ICAP: Indice de Calidad del Aire por Partículas. Es un indicador creado por el artículo 1, letra g, del Decreto Supremo 59, de 1998, del Ministerio Secretaria General de la Presidencia y la Resolución 369, de 1988 del Ministerio de Salud, basado en la cantidad de partículas respirables (PM10), medidas en microgramos, presentes en un metro cúbico. Derivado de la función lineal segmentada definida por los puntos 0 ug/m3 = 0 ICAP, 150 ug/m3 = 100 ICAP y 330 ug/m3 = 500 ICAP.
As a basis for real comparison, the EPA also has a chart for quantities of just Particulate Matter: It seems that the U.S. EPA has a much higher standard based on this chart. The U.S. standards do not even reach 300 (Chilean Pre-emergency), nor 500 (Chilean emergency levels).
Other Good Sources of Information:
Ministry of the Environment (Ontario, Canada)
American Lung Association has some very clear fact sheets:
- Fact Sheet on Ozone
- Fact Sheet on Particulate Matter Pollution
- Overview of Information on Outdoor Air Quality
U.S. EPA
- Air quality guide for Bangkok levels are based on PM and are well below Santiago, currently.
- China -- Beijing is currently at 194 based on particulate matter.
- Mexico City – skies are currently much clearer than here in Santiago.
- The Indian air quality index and standards.

flu and FS culture
I had a really nice morning. I have met a couple of friends (one who leaves forever in three weeks) and we occasionally go out for morning coffee or shopping. Sounds so blase and middle class. It is super fun. This morning we talked about acculturating to the foreign service -- is its own culture. Ellen got me thinking about this when she said that FS folks often have a particular type (very nice) of art collection (third world art gallery, I think she called it). I love you Ellen. (Ellen is an anthropologist.) Anyway, Julie and Shelly and I got to talking about what we are noticing about our new culture (as all relatively recent to the service, although this is Julie's second post). We talked about things that distinguish this culture from other cultures - both experiences and constraints. Ellen, please feel free to comment as I have forgotten the vocabulary of anthropology. Some of the things we came up with include:
- we all have the same furniture (thus the art collections)
- the experience of arrival in a new place with just the nuclear family unit, over and over (tight family units result)
- the language of FS -- yes, the acronyms, but also all the different community members we have: there is a whole set of roles (filled by different individuals in each place) in the community that we all depend upon -- people who fix things, people who acquire the things, people who set up the social gatherings
- everyone in the community knows people all over the world
- normalcy around family separations - of up to or more than a year
- social gatherings where at least 3 first languages are present
I am sure we could come up with a LOT more. We also talked about how the culture of the FS is even more distinct for our kids than it is for us -- babies growing up in this could be said to be "from the Foreign Service" more than from any one place. I shared that this has been the bigger cultural adaption for me -- much bigger than adapting to the San Diegoan culture of Santiago. Anyway -- I invite your comments. It was great to be out with girlfriends waxing philosophic.
Gotta' go -- Doug made a lovely pot of tea!
