Sulfur Dioxide
The ubiquity of sulfur dioxide as an air pollutant combined with reports of effects of the gas and its blood metabolite on DNA and chromosomes, prompted a study of possible mutagen action on mammalian oocytes. Utilizing in vitro and in vivo systems, mouse, ewe, and cow oocytes were examined for cytologic evidence of structural or numerical damage in meiosis. Fragmentation with rearrangement see...
متن کاملDissociation of sulfur dioxide by ultraviolet multiphoton absorption between 224 and 232 nm.
Multiphoton excitation and dissociation of SO(2) have been investigated in the wavelength range from 224 to 232 nm. Strong evidence is found for two-photon excitation to the H Rydberg state, followed by dissociation to SO + O and ionization of the SO product by absorption of a third photon. The two-photon excitation is resonantly enhanced via the C (1)B(2) intermediate state, and the two-photon...
متن کاملMass-independent sulfur isotope fractionation during photochemistry of sulfur dioxide
Mass-independent sulfur isotope signatures are observed in Archean and early Paleoproterozoic sedimentary sulfate and sulfide minerals, and provide the most robust constraints on early atmospheric oxygen levels. Smaller mass-independent sulfur isotope anomalies are observed in ice cores and interpreted as a tracer of stratospheric volcanic loading. Photochemistry of sulfur dioxide (SO 2) has be...
متن کاملPnm-18: Maternal Exposure to Ozone, Nirogen Dioxide, Sulfur Dioxide and Spontaneous Abortion
Background: Adverse pregnancy outcomes (low birth weight, prematurity and intrauterine growth retardation) are associated with exposure to urban air pollution. Experimental data have also shown that such exposure elicits adverse reproductive outcomes. We examined association between spontaneous abortion of the first trimester of pregnancy and ambient concentrations of Ozone, Nirogen Dioxide and...
متن کاملSulfur dioxide emissions in Iran and environmental impacts of sulfur recovery plant in Tabriz Oil Refinery
Background: Combustion of fossil fuels contributes to sulfur dioxide (SO2) emissions. To deal with this issue, the government of Iran has appointed the oil refineries to upgrade their installations and produce high quality fuels. Thus, this study investigated the status of SO2 emissions in Iran and the capability of advanced technologies to control SO2 emissions. Methods: The status of SO2 em...
