note 1: refers to the month of the year with the highest values of sediment<br />
In addition to these values, the afore<br />
mentioned regulations, the content of<br />
pollutants in the air is given in order to<br />
protect the ecosystem, also the target values<br />
for air quality, thresholds and alert<br />
threshold alarms are given as well.<br />
3 MONITORING OF AIR QUALITY<br />
3.1. Places of Measurement<br />
On the basis of insight into the situational<br />
map of the zone, and the situation on the<br />
ground, network of 12 hexagons, has been<br />
created which covers the entire area.<br />
Surface of a hexagon is 0.078 km 2 or area<br />
that covers the entire area of 0.936 km 2 .<br />
The network is made according to the<br />
situation on the ground. It covers the<br />
transport route from the moment of entry<br />
into the populated area and follows the exit<br />
of the village, and the area in which<br />
households are located up to 200 m from<br />
Table 3. Mean monthly concentrations of gaseous pollutants<br />
the transport route. The aim of this kind of<br />
selection of measurement points is to get a<br />
real impact on the transport system<br />
distribution, and change of air quality at the<br />
site around the transport system.<br />
Measurements were carried out for the<br />
sediment dust, airborne dust (total-ULC and<br />
less than 10 m LC-10) as gaseous<br />
pollutants (CO2, CO, SO2, NOx,<br />
formaldehyde and acrolein), in dry and wet<br />
periods (when transport works and does not<br />
work ).<br />
3.2 The Measurement Results<br />
Table 3 shows the average concentrations<br />
of gaseous pollutants for the winter period<br />
of 2010/11 and spring 2011, in Table 4 the<br />
results of measurements of sedimentary<br />
dust emission in table 5, the determined<br />
values of airborne dust emissions.<br />
