Soil quality -- Measurement of enzyme activity patterns in soil samples using fluorogenic substrates in micro-well plates
This standard was last reviewed and confirmed in 2013. Therefore this version remains current.
ISO/TS 22939:2010 specifies a method for the measurement of several enzyme activities simultaneously in soil samples. Enzyme activities of soil vary seasonally and depend on the chemical, physical and biological characteristics of soil. Its application for the detection of harmful effects of toxic chemicals or other anthropogenic impacts depends on the simultaneous comparison of enzyme activities in a control soil similar to the test soil, or on exposure tests with chemicals or treatments.
