Abstract The Conductivity of Bark‐Extracts from Spruce, a Sensitive Indicator for Air Poilution . Bark of spruce is a useful and sensitive indicator for air pollution. The latter may be determined more precisely by electrolytic conductivity of bark extracts than by pH‐value or sulphate level of foliage. By an additional simple sulphate analysis of bark extracts the effects of SO 2 may be distinguished from those of certain components in dust.
