- •
Emissions of PCBs from 13 caulk samples were tested in a micro-chamber system.
- •
Nineteen light ballasts from five manufacturers were tested in 53-L chambers.
- •
Emission rates of PCB congener from caulk and light ballasts were determined.
- •
Several factors that may have affected the emission rates were evaluated.
- •
New data and methods for ranking the primary sources of PCBs were provided.
