Australian and US cement plants (NPI 1999; EPA AP-42 1995). In some countries, the industry is a relatively small contributor to national emissions of these pollutants. For example, the UK National Atmospheric Emissions Inventory (NAEI 2009) showed that the cement industry contributed about 2.5% of the total NO x and 1.0% of the total SO 2

a Relative ratios in AP-42 Section 13.2.2 and 13.2.4 indicate that TSP emission factors may be estimated by multiplying PM-10 by 2.1. Emission for Particles from Aggregate Stock Pile Referring to (AP-42, Section13.2.4, 1/95 Edition) the aggregate storage piles can be calculated.
