ABSTRACT

Development of procedures assessing the impact of hydrological reclamation of open
mines on microclimate, water and soil ecosystems and air quality is the aim of the
project. Unique opportunity of an ongoing hydrological reclamation of the open residual
pit of the Most mine which significantly exceeds the reclamations being made in the
Czech Republic, has been being utilized. The project started in 2011 and is scheduled
for 4 years. Significance of air quality changes near a lake caused by microclimate
changes of the area of interest is evaluated in a partial project which deals with air
quality. Measurement is carried out in two zones and one reference point. Near vicinity
of the lake is the first zone where 8 monitoring stations are situated ca 50 – 100 m from
the lake bank. Further surroundings are the second zone where 3 monitoring stations are
situated ca 50 – 100 m from the lake bank. The reference point is 20 km distant from
the locality. The concentrations of characteristic pollutants for this industrial locality are
observed - SO2, NOx, O3, BTX, VOC, H2S, NH3, dust fallout. Samples are taken in a
passive way. BTX, VOC and dust fallout sample taking period is 30 days and that of the
others is 14 days. Radiello sample taking system is used. In addition to former
pollutants a PM10 aerosol particle concentration is continually measured in the second
zone and the reference point as well FH62IR beta dust meters are use for these
determinations. Partial evaluation of a measurement carried out so far shows a seasonal
dependency of results and a dependency of concentration field spatial distribution on
monitoring station location and on its distance from significant potential pollutant
sources.
