In 1995, approximately <br />488,224 cremations were performed at the 1,155 crematories located throughout the United States. 143 <br />Table 8-1 lists the number of crematories located in each State and the estimated number of cremations <br />performed in each State for 1995 and projections of these totals for the years 1996,2000, and 2010. <br /> <br />Only one set of data are available for the average quantity of mercury emitted for a cremation in the <br />United States. Tests were conducted for a propane-fired incinerator at a crematorium in California. Results <br />of the testing for uncontroIled mercury emissions ranged from 6.26 E-03 to 2.26 E~03 kg/body burned <br />(1.38 E-04 to 4.9 E-03 lblbody); the ayerage mercury emission factor was 1.50 E-03 kg/body burned (3.3 E- <br />03 lblbody).
