er complicated by its proximity to the ocean. Nitryl chloride, a compound created by the reaction of sea salt with an oxide of nitrogen produced in urban atmospheres, can photodissociate into nitrogen dioxide and chlorine atoms. The former is a pollutant, and the latter has been shown to increase ground-level ozone formation. During the summer of 2006, nytril chloride mixing ratios of more than 1 part per billion (ppb) were measured in the Houston urban area. Through photochemical modeling, the authors find that nytril chloride increases the total reactive chlorine mass by 20 to 40 percent in the atmosphere of southeastern Texas. The nytril chloride caused widespread increases in ozone concentrations over Houston of 1 to 2 ppb; vertical dispersion and local atmospheric composition moderated the effect of nytril chloride on ozone mixing ratios.
