AB  - Hazardous Air Pollutants (HAPs) such as exhaust particulate matter (PM), carbon 
      monoxide (CO), sulfur dioxide (SO2), nitrogen oxide (NOx), mercury (Hg) and 
      polychlorinated dibenzo-p-dioxins and polychlorinated dibenzo-furans ( PCDD/Fs) 
      are emitted by the process of cremation and the burning of oblation. Risks to 
      health posed by emissions of hazardous air pollutants from crematories are 
      emerging concerns. Through field investigation and data collection, we obtained 
      the related activity levels and monitored the concentrations of air pollutants 
      from typical cremators, so as to better understand the current pollutants 
      emission levels for crematory. Using the emission factor method, we calculated 
      the emission inventory of HAPs for crematory of Beijing in 2012 and quantified 
      the range of uncertainty. Using atmospheric diffusion model ADMS, we evaluated 
      the influence of crematories on the surrounding environment, and identified the 
      characteristics of air pollution. The results showed that: for the cremators 
      installed with flue gas purification system, the emission concentration of 
      exhaust PM was rather low, and the CO emission concentration fluctuated greatly. 
      However, relative high emission concentrations of PCDD/Fs were detected mainly 
      due to insufficient combustion. Exhaust PM, CO, SO2, NOx, Hg and PCDD/Fs emitted 
      by crematory of Beijing in 2012 were estimated at about 11. 5 tons, 41.25 tons, 
      2.34 tons, 7.65 tons, 13.76 kg and 0.88 g, respectively; According to the results 
      of dispersion model simulation, the concentration contributions of exhaust PM, 
      CO, SO2, NOx, Hg, PCDD/Fs from crematories were 0.05947 microg x m(-3), 0.2009 
      microg x m(-3) and 0.0126 microg x m(-3), 0.03667 microg x m(-3) and 0.06247 
      microg x m(-3), 0.004213 microg x m(-3), respectively.
