NO x isconverted to NO 2 . Umbrous is provided - 0 degrees by colouring a paper filter with the Bacharach’sscale. The content of CO 2 was 7.2%.During the measurements it was found that the greatest emissions were presented by CO; itsaverage was 704.0 mg ∙ m -3 , and by NO 2 , its average concentration was determined as 519.5 mg ∙533 | P age
