Sedimentary dust - total one month 200 350 (note 1)<br />

Pb in sedimentary dust one month 0,1 -<br />

Cd in sedimentary dust one month 0,002 -<br />

Zn in sedimentary dust one month 0,4 -<br />

Tl in sedimentary dust one month 0,002 -<br />

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 />
