加拿大科学家R.M.Koerner和D.Fisher,在北纬81°,西经73°的位置上采集了冰样。经过分析研究,查明了这个地区冰川沉积的酸度发生了明显的变化。研究结果表明,最近二十六年来沉积的冰盖的酸度比距今5000年前形成的冰盖要高得多。 火山资料表明,最近十几年内,任何一次火山喷发,都没有使地球大气中硫的浓度有实质性的增加,可见,冰盖含酸量增加的最大可能性,可以解释为工业的发展及其化学物质喷出量增多的结果。 除研究冰的酸度外,还测定了冰的导电
Canadian scientists R.M. Koerner and D. Fisher collected ice samples at a latitude of 81 ° N and a longitude of 73 ° West. After analysis and research, it was found that the acidity of glacial deposits in this area has undergone obvious changes. The results show that the acidity of ice sheets deposited in the last 26 years is much higher than that of the ice sheets dating back 5,000 years ago. Volcanic data show that no volcanic eruption in any of the last ten years has resulted in a substantial increase in the concentration of sulfur in the earth’s atmosphere. Thus, the greatest possibility of an increase in acidity in the ice sheet can be explained by industrial development and its The result is an increase in chemical output. In addition to studying the ice acidity, the conductivity of the ice was also determined
