Lagrangian measurements of sulfur dioxide to sulfate conversion rates

LWIR Spectral measurements of volcanic sulfur dioxide plumes

This work examines the process of detecting and quantifying volcanic SO2 plumes using the Airborne Hyperspectral Infrared Imager (AHI) developed by the University of Hawaii. AHI was flown over Pu'u'O'o Vent of Kilauea Volcano in Hawaii to collect data on SO2 plumes. AHI is a LWIR pushbroom imager sensitive to the 7.5 11.5 μ region. Spectral analysis and mapping tools were used to identify and c...

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...

Pnm-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...

The Conversion of Thiocyanate Sulfur to Sulfate in the White Rat*

l:lle or&n and fate of thiocyanate ion in the body have been of interest for more than a century. It has been generally accepted that the ion does not readily permeate normal cell membranes; t.hc distribution of thiocyanate ion in the body is the basis of a method for determination of extracellular fluid volume (1). Despite its assumed extracellular localization, thiocyanate ion is physiologica...
