According to Section 5 Par. 1 No. 1 of the 17th Federal Ambient Pollution Control Ordinance (17. BImSchV) the parameter "total dust" is be observed continously. No daily average value may exceed 10 milligrams/m³, no half- hour average may 30 milligrams/m³.
But how is "total" dust defined? One would think it is the total amount of all dust particles, no matter how small they are. Critics ask for more details: Does this refer to coarse dust? From what particlesize on - 20 micrometers, 10 micrometers diameters? Are fine (respirable) dust particles from 0.1 to 10 micrometers diameter included, or even finest dust less than 0.1 micrometer in diameter? en.wikipedia.org/wiki/Micrometer
"Total" dust is a more or less antiquated technical term. The German "TA Luft" ( de.wikipedia.org/wiki/TA_Luft ) established 1974 distinguishes between total dust and fine dust and sets a particle size of 10 micrometers as the upper limit of fine dust ( 15 ).

Hence, the measured parameter "total" dust comprises mainly coarse dust (bigger than 10 micrometers). The continous observing of htis dust fracrion is the most convenient for measuring purposes ( 2 )
Today we know that fine and finest dust is considerably more relevant to health than coarse dust. Particles of fine and finest dust are still big enough to effectively transport very problematic molecules of heavy metals ( en.wikipedia.org/wiki/Heavy_metal_(chemistry) ), dioxins ( en.wikipedia.org/wiki/Dioxin ) or asbestos fibres ( en.wikipedia.org/wiki/Asbestos ). In this context Dr. D.H.Buss emphasized the special danger of contaminated nanoparticles ( en.wikipedia.org/wiki/Nanoparticle )due to their high mobility in tissues and cells ( 14 ).
A more diversified categorization of the quality of dust emissions should have been established with the update of 17. BImSchV in the year 2003 at latest. Today we have to demand as definite quality features of laws and regulations targeting the damaging effects of flue gases: the detailed assessment of coarse, fine and finest dust, if necessary also ultrafine dust, and their distribution according to particle size and chemical composition.
Temporal and local fluctuations of dust charges in the large cross- sections of the flue gas streams occuring in WIPs also should have been considered in the present legal and technical standards. Suitable recommendations and measurement procedures are definitely available, as described below. But apparently it was convenient to use the word "total" to let the people think that the total dust emissions of "modern WIPs" are insignificant.
