laying down the limits and conditions for the monitoring, assessment, evaluation and management of air quality
The Government mandates pursuant to § 55 (1) of Act No. 86 / 2002 Coll., on Air Protection and on the amendment of certain other laws (Air Protection Act) ("the Act '):
§ 1
Subject matter
This Regulation lays down, in accordance with the law of the European Communities (1), the limits of imitation, tolerance, target limits and long-term objectives. Furthermore, a method of assessing the level of air pollution, the area and the location with deteriorated and good air quality and the principles for measuring the level of air pollution shall be laid down.
§ 2
Basic concepts
For the purposes of this Regulation:
(a) the target limit - the concentration of the pollutant in ambient air determined for the purpose of eliminating, preventing or limiting harmful effects on human health and the environment overall, to be achieved, where possible, within a given time;
(b) a long-term objective for ozone - a level of tropospheric ozone air pollution below which direct harmful effects on human or animal health or the environment can be excluded on the basis of current scientific knowledge;
(c) an assessment of air quality - provided by this Regulation or, where appropriate, by the air protection authorities, an approved method for carrying out measurements, calculations, forecasts or expert estimates of air pollution levels;
(d) upper limit for the assessment of the level of air pollution - the value of the concentration of the pollutant at which only measurements must be used to assess the level of air pollution when reaching or exceeding a given territory;
(e) lower limit for the assessment of the level of air pollution - the value of the concentration of the pollutant below which only model calculations or expert estimates may be used to assess the level of air pollution in a territory;
(f) reference method of measurement - a procedure that includes a description of the sampling, transport and modification of the air sample and the determination of the concentration of the substance;
(g) equivalent method - a method which is proven to be of the same quality characteristics and which provides the same, in the case of methods of diffusion of pollutants in air comparable results to the reference method;
(h) nitrogen oxides - a mixture of nitric oxide and nitrogen dioxide, the concentration of which is the sum of the concentrations of nitric oxide and nitrogen dioxide, calculated in ppbv units and expressed as nitrogen dioxide in micrograms per cubic metre;
(i) suspended particles - particles which, due to negligible falling speed, persist for a long time in the atmosphere;
j) suspended particles of the fraction PM10 - particles which pass through the size-selective input filter showing 50% for the aerodynamic diameter of 10 μm separation efficiency;
(k) fine suspended particles of the fraction PM2,5 - particles which pass through the size-selective input filter showing 50% for the aerodynamic diameter of 2,5 μm separation efficiency;
(l) method for calculating the dispersion of air pollution (diffusion method) - method for calculating the concentrations of pollutants and their dispersion over time and space;
(m) ozone precursors - pollutants entering photochemical reactions leading to tropospheric ozone formation;
(n) deposit limit - the maximum permissible amount of air pollutants settled or absorbed on the surface area unit per time unit due to the extraction and eradication processes from the atmosphere which do not cause any negative effects and processes in the ecosystem;
(o) the liner source of air pollution - transport communication used for the operation of mobile sources of air pollution or proposed for use for the operation of such sources within the framework of territorial, building, housekeeping or other management;
(p) dusty fall - the mass of depondered material which, after previous air pollution, has settled per unit of surface area per time unit as a result of extracting and eradicating processes from the atmosphere,
(r) tropospheric ozone - ozone in the ground layer of the atmosphere and arising from the chemical reactions of ozone precursors.
§ 3
Imitation limits, tolerance limits, target limit and long-term objectives, deposit limit
(1) The limits and tolerance limits are set for these pollutants

Location of sampling points (measuring points) for measuring concentrations of pollutants in ambient air

Classification of sampling points for continuous measurement of concentrations of sulphur dioxide, suspended particles, nitrogen dioxide and oxides of nitrogen, lead, carbon monoxide and benzene in ambient air and selection criteria
1. Placing of sampling points on a macroscale
1.1.Protection of human health
1.1.1. The sampling points aimed at protecting human health shall be positioned in such a way that:
(a) provide data on locations in areas with impaired air quality and on residential groupings where peak concentrations occur, the population of which is likely to be exposed directly or indirectly for a period of time relevant to the average of the relevant limit value (limit values);
(b) provide data on levels in other locations within areas with impaired air quality and residential groupings which are representative of the exposure of the general population.
1.1.2. Sampling points are placed
(a) in such a way as to prevent measurements in and around very small micro-environments.
(b) represent, where possible, air quality in the surrounding area of at least 200 m2 for transport-oriented sites and several square kilometres for urban sites;
(c) to represent, where possible, similar sites which are not in their immediate vicinity in order to ensure that the number of measuring points is minimised while maintaining the required network efficiency.
1.2. Protection of ecosystems and vegetation
The sampling points aimed at protecting ecosystems or vegetation shall be located more than 20 km from the housing clusters or more than 5 km from other built-up areas, industrial installations or motorways. The sampling point shall normally be located in such a way as to represent the air quality in the surrounding area of at least 1000 km2.
2. Microscale sampling points
2.1. The sampling points shall be located, if possible, so that:
(a) the air flow around the inlet of the sampling probe is not limited by any obstacle affecting the air flow around the sampling device (usually several metres from buildings, balconies, trees and other obstacles and at least 0,5 m from the nearest building in the case of sampling points representing the ambient air quality in the area of the line starting with the installation);
(b) the inlet of the sampling probe of the sampling device was between 1,5 m (respiratory zone) and 4 m above the ground. Higher positions (up to 8 m) are necessary and appropriate if the data obtained by the station are to be representative of larger areas,
(c) the inlet of the sampling probe of the sampling device has not been located in the immediate vicinity of the sources of air pollution, in order to avoid direct sampling of emissions undiluted by mixing with ambient air;
(d) in the case of the sampling probe outlet of the sampling device, the recirculation of the flowing air collected back into the sampling device inlet is not prevented;
(e) transport-oriented sampling equipment
1. for the measurement of all pollutants, at least 25 m from the edge of the major junctions and at least 4 m from the centre of the nearest lane;
2. for the measurement of nitrogen dioxide and carbon monoxide, the inlet openings of the sampling probe have a maximum of 5 m from the edge of the road (from the curb),
3. for the measurement of material particles, lead and benzene, the inlet orifices of the sampling probe were located in such a way as to represent the air quality near the starting line.
2.2. Sampling points shall also be placed in such a way that the following factors are taken into account:
(a) co-operating sources of air pollution
(b) operator safety of the sampling device
(c) accessibility to the sampling device;
(d) availability of electricity and telephone connections;
(e) visibility of the site in relation to its surroundings;
(f) public safety,
(g) requirements for the common location of sampling devices for different pollutants;
(h) zoning requirements.
3. Documentation and review of the selection of seats
The selection procedure and selected sampling points shall be documented at the classification stage according to the criteria of the European Environment Agency. It is mandatory to take photographs of the surrounding area in the direction rose (in all directions covering the whole range of compass sections) and detailed maps. The location of sampling points shall be reviewed regularly and new documentation shall be taken to demonstrate the continuous validity of the selection criteria.
