A new preanalytical holding-time approach called [open quotes]practical reporting time[close quotes] (PRT) has been developed that depends on the probability of an analyte measurement being below a critical concentration. This new approach has been applied to 19 volatile organic compounds and four explosives in both water and soil matrices. Practical reporting times for these analytes are used to develop a nomograph to show the consequences of chemically analyzing environmental samples past their PRT. This nomograph can be applied to a large class of analytes that uses zero-order or first-order kinetic models to approximate the degradation of analyte concentrations. 14 refs., 6 figs., 5 tabs.
