--------------------------------+=== Trend discussion (for key categories) === 
  
-===== Uncertainties =====+All trends in emissions correspond to trends of emission factors in table above and of production development. No rising trends are to identify.
  
-Emission factors: Relative error rates at ±15% and ±25% (Adhesive manufacturing, magnetic tapes manufacturing, photographs manufacturing) were applied, but not exceeding 100% or falling below 0%. Uncertainties refer to a 95% confidence interval.+[{{sector:ippu:other_solvent_and_product_use:chemical_products:em-NMVOC_2D3g-bitumen-blowing.png | Trend of annual NMVOC and TSP emissions from bitumen blowing }}]

 +===== Uncertainties =====
  
 +Emission factors: Relative error rates at ±15% and ±25% (Adhesive manufacturing, magnetic tapes manufacturing, photographs manufacturing) were applied, but not exceeding 100% or falling below 0%. Uncertainties refer to a 95% confidence interval. For bitumen blowing emission factor uncertainties are on a higher level just to 100%. For Cd and TSP the uncertainty are even greater than a factor of two.
