Laboratory research involving three different limestones, four solid fossil fuels and nine types of biomass has shown that biomass significantly reduces the reactivity of calcined limestone in desulfurization of combustion products. This negative effect can be attributed to coating of CaO with various products of biomass and coal combustion. © 2014 Czech Society of Chemical Engineering. All Rights reserved. Source

As a consequence of the growing production and use of asbestos and inorganic fibres, measurement of their concentration in indoor air is of great importance. The relevant legal regulations require the measurement. Various methods were developed for the purpose, based on collecting airborne particles in capillary membrane filters and subsequent determination of their number concentration. Remediation of buildings with fiber-containing construction elements is an essential part of any reconstruction. Source

Ozone and NOx concentrations in the ambient air and rainfall were measured in different distances (40-900 m) from heavy-traffic-loaded highway D1 near Prague. In addition, their influence on the health of Norwegian spruce (Pice abies (L.) Karst.) forest stands was estimated. Atmospheric measurement proved that only vehicles moving up affect the air quality in a distance up to 50 m. Though no statistically significant differences in crown parameters were found, some indicators of long-term stress impact showed a big stress load on the site A1 situated only 40 m from the highway.
