The influence of gaseous ammonia and sulphur dioxide on the formation of 2378-substituted PCDD/F on a reference flyash from a municipal waste incinerator has been investigated using a laboratory scale fixed-bed reactor. The reference flyash samples (BCR-490) was reacted under a simulated flue gas stream at temperatures of 225 and 375°C for 96h. The experiments were carried out in two series: fi...

Heather (Calluna 6ulgaris) was grown in pots in a natural heathland soil and exposed in outdoor fumigation chambers (‘solardomes’) to 40 nl l of both nitrogen dioxide (NO2) and sulphur dioxide (SO2) simultaneously. Plants exposed to NO2 and SO2 for 8 months over a growing season (February–November) showed increases in the growth of shoots (+37%) and the whole plant (+15%) and a raised ratio of ...

The tremendous decline of combustion-derived emissions of traditional air pollutants such as sulphur dioxide (SO2) and total suspended particles (TSP) in Eastern Germany shortly after German reunification in 1990 provided the unique opportunity to study trends of prevalence of respiratory illness along with the improvement of air quality. The present review focused on the results of two repeate...

In recent years more and more focus has been placed on the environmental aspects of ships, because of the great attention to exhaust gas emissions from ships including CO2, a leading contributor to Green House Gasses (GHG) emissions, due to their negative effect on global warming. Maritime transport has clear environmental advantages: it expends relatively little energy and its infrastructure r...

Flow injection analysis (FIA) methods for the spectrophotometric determination of CO2 and SO2 in wines are described. The determination of CO2 is based on the colour change of a low capacity buffer (containing an acid-base indicator) due to the dissolved carbon dioxide. The determination of SO2 is based on the decoloration of malachite green by sulphur dioxide. Two FIA manifolds are presented; ...

Falling back past few years rapid progress in Air pollution has become a life-threatening concern many nations throughout the world due to human activity, industrialisation, and urbanisation.. As result of these activities, sulphur oxides, carbon dioxide (CO2), nitrogen monoxide (CO), chlorofluorocarbons (CFC), lead, mercury, other pollutants be emitted into atmosphere. Simultaneously, estimati...
