SUMMARY
SYMPOSIUM FINDINGS SYMPOSIUM FINDINGS
Indoor sources account for 75-98% of exposure to many VOCs.
“A typical pollutant release indoors is 1000 times as effective in causing human exposures as the same release to urban outdoor air.”
Indoor source reduction or removal is the most effective strategy.
Some schools have problems of poor ventilation, mold growth, and elevated formaldehyde levels.

CONTROL MEASURE FOR COMPOSITE WOOD PRODUCTS
Plan to develop air toxics control measure to reduce emissions from formaldehyde-containing composite wood products
Timing– Establish workgroup: Spring 2001– Evaluate exposure/
control options: Fall 2001– Public workshop: Winter 2001- 2002 – Staff proposal: Spring 2002– Board Hearing: Summer 2002

Portable Classrooms
PORTABLE CLASSROOMS STUDYPORTABLE CLASSROOMS STUDY
Statewide study jointly conducted
by ARB and DHS
AB 2872, Shelley
Phase I: Mail survey
– Questionnaires to 1000 schools
– Formaldehyde samplers - 800 schools
PORTABLE CLASSROOMS STUDY(continued)
PORTABLE CLASSROOMS STUDY(continued)
Phase II: Main field study
- 240 classrooms, both portables and traditional
- Gaseous and particulate pollutants
- Temperature, humidity, noise
- Floor dust samples, airborne molds
Report to Legislature due June 2002
SCHOOL BUS STUDY(Planned)
SCHOOL BUS STUDY(Planned)
Inside bus, outside bus, bus stops, and ambient
Diesel, diesel retrofit, gasoline, natural gas-powered buses
Real-time measurements: PM, VOCs, other
Pilot study - August 2001, in Los Angeles
PERSONAL PM EXPOSURE STUDIES PERSONAL PM EXPOSURE STUDIES
COPD patients in Los Angeles– Relative contributions of indoor and outdoor
sources to personal PM2.5 exposures
Complementary study of healthy persons in Los Angeles – Includes real-time measurements of PM2.5,
chemical components, air exchange rates
Personal Exposure Monitoring
RESIDENTIAL INDOOR COOKING STUDY
RESIDENTIAL INDOOR COOKING STUDY
Different cooking activities
Gas and electric stoves
Very high levels of some pollutants– Stove top cooking (gas): PM10 = 60 to 1400 g/m3
– Self-cleaning cycle (gas): PM10 > 3600 g/m3
Practical methods to reduce exposures
Results - to provide guidance to the public, and improve exposure estimates

SUMMARY
FUTURE ACTIONS FUTURE ACTIONS
Use Board’s authority to reduce emissions from a major indoor source:
- formaldehyde ATCM
Expand public education efforts
Address indoor exposures as part of community health activities
Use results from Portable Classrooms Study and School Bus Study to develop recommendations to protect children’s health.

SUMMARY
SUMMARY SUMMARY
Many State agencies and private organizations are engaged in activities that promote healthy indoor environments.
Need focused leadership at the State level.
Current attention is on schools, State buildings, and energy needs.
Need support for emissions reductions measure and other actions.
