Apr 01, 2007 · Previous work has suggested that chlorine may be present at zero or micro grammes per kg (ppb) levels (Kim and Ok, 2005) or that it was adequate to impute chlorine content of fuels by reference to a few (5 in total) dated literature values for fuel types (Cooper, 2005). In both cases, it was suggested that emissions of PCDD/F (based on very few samples) could be correlated with chlorine content. The relative formula mass of a compound is calculated by adding together the relative atomic mass values for all the atoms in its formula. Moles are units used to measure substance amount.
