From the Lawrence Daily Journal-World for Oct. 22, 1986:

  • Some Kansas University scientists were at odds with others in their field regarding the cause of ozone depletion near the South Pole. Edward Zeller, a KU professor at the Space Technology Center who made frequent trips to Antarctica to study the phenomenon, said chemical reactions caused by solar flares were more likely than man-made chlorofluorocarbon chemicals to be harming the protective atmospheric layer. "I agree those chemicals seem to be a problem," Zeller said. "But I don't think they're doing all the damage."
  • Representatives from the Kansas Department of Health and Environment were asking to meet with officials from Farmland Industries to discuss possible causes of a chemical release that had recently affected southeast Lawrence. Plant supervisor Don Clark had confirmed that the crystalline residue had been ammonium nitrate, but he added that company investigators had not yet been able to determine the cause of the release.
