This is not one of the sections on which there is considerable argument. It states: "'emission limit value' means the mass, expressed in terms of a specific parameter, concentration or level of an emission, or both a specific concentration and level of an emission, which may not be exceeded during one or more periods of time:". I cannot follow this definition. A mass expressed as a concentration is incorrect technically. Generally, one expresses a mass as a level, not a concentration.

I do not want to play "I know more than you" games as I probably do not. However, unless the definition has been transposed from an EU directive, in which case we would be stuck with it, it should be examined by somebody with a reasonable degree of technical skill. While the phraseology appears to be poor, it is possible that it is long established. Even if that is the case, it deserves to be examined, given that a mass expressed in terms of a specific concentration is meaningless. Either one has a mass or a concentration. While a concentration can be used to determine a mass, a mass cannot be expressed in terms of a concentration.
