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.

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

FUTURE ACTIONS

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.
