1.1 This practice specifies the procedure for the calculation of first order rate constants and using that calculation to estimate the environmental persistence of materials.
Estimating how long a material is expected to remain in a specific environment is important in understanding the expected long-term environmental impact and the potential for accumulation over time. This standard provides a standardized method for calculating a first order rate constant and applying that calculation to estimate the persistence of the material.
