Outline:

1. Indoor monitoring of PM10 in two houses and a school in two colonias ladrilleras.

2. Survey of families in colonias.

3. Relocation issues

1. Over 100 brick kiln sites in the urban area of San Luis Rio Colorado, Sonora, concentrated within three small colonias ladrilleras.

2. Brick-makers’ families live at the brick-making sites.

3. Some of the local schools are either near to or surrounded by brick kiln sites.

4. On-going effort by city to relocate brick-makers to area south of city limits near wastewater treatment plant (but have families stay at current locations).

Background

Active burning stage – about 1 day, black smoke dominated by soot, fine soil dust, and “brown carbon”. Smoldering phase another 2 days.Plume tends to stay close to surface for significant distances.

Things to do:

1. Further treatment of survey results.

2. School absentee data and burning permits for La Grullita.

3. Design and print handout on health problems associated with brick kiln smoke, including lead from burning painted boards.
