Emissions Testing Results Page 1 of 3 Home About CANA Membership Testing Results: Visible Emissions: The visible emissions were evaluated every 15 seconds and rated on a scale from 0% to 100% opacity by a qualified inspector. Cremationist The opacity readings for each cremation were then averaged over the six-minute period with the highest emissions. Figure 1 shows that visible emissions increased as the operating temperature increased. Comparison is given to a typical state emission limit. Statistics EnvironmentaJ Li n ks HistolY Particulate Matter: The results of sampling show that particulate matter emissions also increased with temperature. Overall, the emissions of particulate matter were very low. Burial At Sea The average test results for particulate matter (shown in Figure 2) as well as the results for all of the following pollutants, are for the inlet to the scrubber. A comparison of the emissions before and after the water scrubber showed that the device had little to no effect on the emissions of any of the pollutants. Carbon Monoxide: The levels of carbon monoxide (flgure 3) were very low for each test condition, well below the typical state standard of 100 parts per million. Nitrogen Oxides and Sulfur Dioxide The levels of these gases (shown in Figures 4 and 5) were within acceptable limits. Hydrogen Chloride: Hydrogen chloride (HCI) is a gaseous pollutant produced by the burning of plastics or other material containing chlorine. The HCI emissions would not be expected to change with temperature. The average HCI emission for all the conditions was 0.15 pound per hour of operation. Metals: Like HCI, emissions of mercury, cadmium, and lead are not expected to vary with operating temperature. The metal of concern from crematories is mercury, which http://www .cremationassociation.org/html/tescresults.html 06/20/2001
