DESCRIPTION
PD ISO/TS 22939:2019 - TC
This standard PD ISO/TS 22939:2019 - TC Tracked Changes. Soil quality. Measurement of enzyme activity patterns in soil samples using fluorogenic substrates in micro-well plates is classified in these ICS categories:
- 13.080.30 Biological properties of soils
This document specifies a method for the measurement of several enzyme activities (arylsulfatase, ? ?glucosidase, ? -glucosidase, Cellubisidase, ? -Xylosidase, phosphodiesterase (PDE), chitinase, phosphomonoesterase (PME), leucine-aminopeptidase, Alanine-aminopeptidase) simultaneously (or not) using fluorigenic substrates 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.
