Abstract	Sulfur dioxide (SO?) is a toxic gas and air pollutant. The toxic effects of SO? have been extensively studied. Oxidative damage due to SO? can occur in multiple organs. Inhaled SO? can also cause chromosomal aberrations, DNA damage and gene mutations in mammals. However, SO? can also be generated from the sulfur-containing amino acid, L-cysteine. Recent studies have shown that SO? has a vasorelaxant effect, and ameliorates pulmonary hypertension and vascular remodeling. SO? can also reduce lung injury and myocardial injury in rats. In addition, SO? reduces myocardial ischemia-reperfusion injury and atherosclerotic lesions. Therefore, SO? exerts both detrimental and protective effects in mammals. Is SO? a foe or friend for life?.

Sulfur Bohr Model The number of electrons in each of Sulfur's shells is 2, 8, 6 and its electron configuration is [Ne] 3s² 3p⁴. In its elemental form, sulfur has a light yellow appearance. The sulfur atom has a covalent radius of 105 pm and a Van der Waals radius of 180 pm. In nature, sulfur can be found in hot springs, meteorites, volcanoes, and as galena, gypsum, and epsom salts. Sulfur has been known since ancient times but was not accepted as an element until 1777, when Antoine Lavoisier helped to convince the scientific community that it was an element and not a compound.
