Abstract:

This investigation was undertaken to measure atmospheric ozone and related factors in northern Greenland, in an attempt to identify the environmental factors which were responsible for the excessive cracking of tires and other rubber items in storage. Atmospheric ozone concentrations were found to range from zero to 1.3 parts per hundred million pphm during the five-day period in July, 1960 when measurements were made. The maximum values occurred during the middle of the day when sunlight intensity was at a maximum values of zero or very near zero were found during nighttime hours when the sun was nearer the horizon, or during periods of fog or cloudy weather. This was during the period of 24-hour daylight. It was concluded that atmospheric ozone occurs in northern Greenland by the same mechanism responsible for ozone formation in other locations. There was no evidence to indicate that ozone was brought to the sampling location by any unique transport mechanism, even though some of the meteorological and topographic factors indicated that such phenomena might occur. Deterioration of rubber was evidently due to atmospheric ozone, although low temperatures or other environmental factors may have also contributed to the observed effects. Author
