Table 2. Air quality limit values for dust sediment Polluting matter Sampling period The allowed average value (mg/m 2 day) The allowed high value (mg/m 2 day) Sedimentary dust - total one month 200 350 (note 1) Pb in sedimentary dust one month 0,1 - Cd in sedimentary dust one month 0,002 - Zn in sedimentary dust one month 0,4 - Tl in sedimentary dust one month 0,002 - note 1: refers to the month of the year with the highest values of sediment In addition to these values, the afore mentioned regulations, the content of pollutants in the air is given in order to protect the ecosystem, also the target values for air quality, thresholds and alert threshold alarms are given as well. 3 MONITORING OF AIR QUALITY 3.1. Places of Measurement On the basis of insight into the situational map of the zone, and the situation on the ground, network of 12 hexagons, has been created which covers the entire area. Surface of a hexagon is 0.078 km 2 or area that covers the entire area of 0.936 km 2 . The network is made according to the situation on the ground. It covers the transport route from the moment of entry into the populated area and follows the exit of the village, and the area in which households are located up to 200 m from Table 3. Mean monthly concentrations of gaseous pollutants the transport route. The aim of this kind of selection of measurement points is to get a real impact on the transport system distribution, and change of air quality at the site around the transport system. Measurements were carried out for the sediment dust, airborne dust (total-ULC and less than 10 m LC-10) as gaseous pollutants (CO2, CO, SO2, NOx, formaldehyde and acrolein), in dry and wet periods (when transport works and does not work ). 3.2 The Measurement Results Table 3 shows the average concentrations of gaseous pollutants for the winter period of 2010/11 and spring 2011, in Table 4 the results of measurements of sedimentary dust emission in table 5, the determined values of airborne dust emissions.

As the largest measured values obtained at the measuring point 7 (20 m from the alignment of transport) are in Tables 3 and 5, and because of space, the results of this measurement with the measuring point. 191
