Abstract
The explosive global change in the emissions of Sulphur dioxide (SO2) over the decades have brought about tremendous effects in the regional as well as global scale in the composition and quality of air that we breathe. The global SO2 emission peaked in the 1970s, decreased until 2000 and has risen to peak again mainly as the result of increased globalization in developing countries. The global estimation is surprisingly low but the regional output of SO2 is high. The main hotspots being in East Asia Countries. The Sulphur aerosols not only impacts the animals’ health, but those of the ecosystems at large. SO2 contributes to global warming, ozone depletion, acid rain, smog etc. that has brought disastrous environmental conditions. WHO recommends a maximum exposure of not more than 0.5 ppm for around 24 hours’ span. SO2 reacts with other gases to form sulphate particles, constituent of particulate matters i.e. PM 2.5 concentrations, the exposure to which causes skin, respiratory, reproductive failures and cardiovascular ailments. This study, as such, is meant to bring into light the sources of SO2 and its harmful effects on health and environment at large. Air pollution is a major issue with adverse effects prevailing over the globe at present.
Highlights
What is Sulphur dioxide? Sulphur dioxide (SO2) belongs to Sulphur oxides, a group of highly reactive gases, with a mol.wt. of about 64.07 g/mol, density of 2.26 g/L with respect to air, boiling point of -10 oC and freezing point of -73oC
The widespread fossil fuels combustion has greatly increased sulphur dioxide emissions such that the man-made sources surpasses the natural sources in the total global estimate [1]
Modern equipments like that of the sulphur dioxide analyser and Differential Optical Absorbance Spectroscopy (DOAS) should be considered preferably to estimate the sulphur content in air so as necessary steps for its control could be taken based on the sulphur standards
Summary
What is Sulphur dioxide? Sulphur dioxide (SO2) belongs to Sulphur oxides, a group of highly reactive gases, with a mol.wt. of about 64.07 g/mol (heavier than air), density of 2.26 g/L with respect to air, boiling point of -10 oC and freezing point of -73oC. Of about 64.07 g/mol (heavier than air), density of 2.26 g/L with respect to air, boiling point of -10 oC and freezing point of -73oC. It is a colorless pungent gas soluble in water and slightly to an extent in sulphuric acid, acetic acid and even alcohol. SO2 is produced as precursor of sulphur trioxide (SO3) in industries to make sulphuric acid, sulphurous acid, sulphides etc. It is used widely as a disinfectant, bleach, refrigerant and as preservatives in food items
