An ice core in south Greenland covering the period 1869 to 1984 was analyzed for oxygen isotopes and chloride, nitrate, and sulfate concentrations. The data show that the "excess" (nonsea-salt) sulfate concentration has tripled since approximately 1900 to 1910 and the nitrate concentration has doubled since approximately 1955. The increases may be attributable to the deposition of these chemical specis from air masses carrying North American and Eurasian anthropogenic emissions.
对格陵兰岛南部一段覆盖1869年至1984年的冰芯进行了氧同位素以及氯化物、硝酸盐和硫酸盐浓度的分析。数据显示，自大约1900年至1910年以来，“过剩”（非海盐）硫酸盐浓度增至三倍，自大约1955年以来，硝酸盐浓度翻了一番。这些增加可能归因于携带北美和欧亚人为排放物的气团中这些化学物质的沉降。
