Sulphur dioxide (SO2) is one of the major atmospheric contaminant that induces negatively effects in the cellular biochemistry and physiology of the plants. However, Rhizobium inoculation can cause increas in plant resistance to abiotic and biotic stresses. In this study, effects of different concentrations of Sulphur dioxide gas (0, 0.5, 1, 1.5 and 2 ppm) on photosynthetic pigments, proline, p...
This study explores the relationship between happiness and air pollution in Britain using data from the British Household Panel Survey (BHPS). The effects of air pollution on individuals’ happiness are estimated and their monetary value is calculated. In particular, three air pollutants are examined in this paper; the sulphur dioxide (SO2), the ground-level ozone (O3) and the nitrogen dioxides ...
In the present work, a sequential injection system with spectrophotometric detection was developed for the determination of free and total sulphur dioxide in wines. It was based on the formation of a coloured product from the reaction among SO2, formaldehyde and pararosaniline. A gas diffusion unit (GDU) was incorporated into the manifold to prevent the wine matrix interference in the spectroph...
Monitoring gaseous and particulate volcanic emissions with remote observations is of particular importance for climate studies, air quality and natural risk assessment. The concurrent impact of the simultaneous presence of sulphur dioxide (SO2) emissions and the subsequently formed secondary sulphate aerosols (SSA) on the thermal infraRed (TIR) satellite observations is not yet well quantified....
The sulphur cycle plays fundamental roles in the chemistry1–3 and climate4,5 of Venus. Thermodynamic equilibrium chemistry at the surface of Venus favours the production of carbonyl sulphide6 and to a lesser extent sulphur dioxide. These gases are transported to the middle atmosphere by the Hadley circulation cell7,8. Above the cloud top, a sulphur oxidation cycle involves conversion of carbony...
Co-combustion of biosolids with coal or other biomass fuel can play a significant role in combustion facilities for energy production and waste management policy context. This paper presents the results of an experimental study to investigate the use of biosolids for co-combustion with wood pellets in a wood pellet stove. Fuel property, gas emissions and stove efficiency are compared. In regard...
The aim of the present study was to investigate whether repeated peak exposure (gassings) to sulphur dioxide (SO2) and other irritant gases increases the risk of new-onset asthma. A questionnaire was sent to 4,112 sulphite workers, of whom 1,919 completed the questionnaire and 396 completed the short-form questionnaire, which was sent out as a last reminder. A sample of 130 nonrespondents compl...
OBJECTIVES Ambient exposure to sulphur dioxide (SO2) has been previously associated with emergency department (ED) visits for migraine headaches. In the present study, the objective was to examine the relationship between ED visits for migraine and ambient sulphur dioxide concentrations. DESIGN AND METHODS This was a time-series study of 1059 ED visits for migraine (ICD-9: 346) recorded at a ...
Abstract: Sulphur dioxide (SO2) is one of the main air pollutants that can cause imbalance in growth and physiological function of plant in high concentrations. Rhizobium-plant symbiosis can cause increasing in plant resistance to abiotic and biotic stresses in addition to increase growth of plant. In this study, effects of Rhizobium (native and standard strains) on leaf anatomical parameter...
Coal is a major energy source, and on the other hand coal is a source of pollution. Some of the important environmental issues related to use of coal in energy production are the release of sulphur dioxide (SO2). SO2 is a precursor to acid rain, responsible for atmospheric pollution and damage to human health. Therefore, investigations and development of technologies promising low SO2 emission ...
