The levels of particulate matter at all three 1 0.010 temperatures were found to be lower than that from a standard 0.5 0.004 0.001 home fireplace.

Only the emissions at 1800 F reached an opacity level higher than 5 percent, the level at which emissions are visi- 0,45 Q'5 ble to the human eye.

"They would tell you it would be just the reverse. But this is reality. This is fact." Particulate matter levels actually increased slightly after going Smoke through the scrubber. According to Rahill, this occurred because crematory pollutants are corrected to a standard oxygen level. The introduction of water increases oxygen levels, thereby amplifying Implications the correction and the resultant levels of some pollutants. A final report on the stack testing at Woodlawn was due out in /iaK Mercury. According o Rahill, mercury emissions were found g September, shortly after press time. Based on the preliminary to be " uit and fairly s."By comparison, levels of information, Rahill concluded: "The data is extremely consistent with what data we do have, so there were no shocks. We do see a consistent thread throughout the data that the higher the tempera- ture, the worse the emissions get, and it's going to be interesting when we go back to the EPA to start negotiating again how they're 4.7 going to deal with that.
