Dusts - Emissions and Pollutions 1991
The dust emissions recorded are represented in 1 × 1 km aeeas both on a colored grid and as absolute values.
However, in the evaluation of the total dust constituents shown here it must be taken into consideration that only the quantities of the dust constituents already present in particle-form at the time of emission are dealt with here. As described in the overview, a large part of the dusts later registered as emissions are emitted in gaseous form and as such are included in the emission calculations for other substances (sulfur dioxide, nitrogen oxide and organic gases) where they are also represented quantitatively.
The representation of the measured pollution in the case of floating dust and floating dust constituents is slightly different to that used in the 1985 Environmental Atlas. The limit values IW1 and IW2 of the 1986 TA-Luft, where known, were chosen as class value for the delimitation of the highest class.
Due to the relatively even distribution and the high density of monitoring points a surficial distribution analogous to that of the gaseous emissions can be shown. The interpolation was done by hand (Maps 03.04.2 and 03.04.3). In addition the respective values of the BLUME-monitoring stations are represented.
The floating dust constituents lead and cadmium (Maps 03.04.5 and 03.04.6) are shown as colored class values with reference to the monitoring points and as classified rounded individual values as in the case of dust precipitation. According to today’s level of knowledge the small number of monitoring points does not permit the application of grid-like or surficial representations.
As TA-Luft gives no limit values, the dot diagram on carcinogenic heavy metals in floating dust (Map 03.04.4) was evaluated with recourse to the current index values and reference values of various sources. However, the index values are in part significantly lower than those in the 1985 Environmental Atlas map. The individual values of all four substances shown are presented as bar charts.
The evaluation and representation of the dust precipitation and its constituents only take account of monitoring points with class value and rounded individual value, as was the case with the representation in the 1985 Environmental Atlas. The distinct dependence of pollution levels on the proximity to the pollution source does not allow surficial representation. But it can be shown by use of symbols whether monitoring points are located in the immediate vicinity of main roads or on median strips.
