A Destroyed Medical Waste is Regulated medical waste that has been ruined, torn apart, or mutilated through thermal treatment, melting, shredding, grinding, tearing, or breaking, so that it is no longer generally recognized as medical waste, but has not yet been treated (excludes compacted regulated medical waste).

A Destruction and Removal Efficiency (DRE) is a percentage that represents the number of molecules of a compound removed or destroyed in an incinerator relative to the number of molecules entering the system (e.g.

A Destruction Facility is a facility that destroys regulated medical waste.

A Desulfurization is Removal of sulfur from

A Detectable Leak Rate is the smallest leak (from a storage tank), expressed in terms of gallons- or liters-per-hour, that a test can reliably discern with a certain probability of detection or false alarm.

In the context of the environment, "detection" refers to the process of identifying or recognizing the presence or occurrence of certain elements, phenomena, or changes in the environment. It involves using various techniques, tools, and methods to observe, measure, and analyze environmental conditions. Detection plays a crucial role in understanding and managing environmental issues, including monitoring natural resources, assessing pollution levels, and studying ecosystem dynamics.

A Detection Criterion is a predetermined rule to ascertain whether a tank is leaking or not. Most volumetric tests (volumetric tank tests) use a threshold value

The Detection Level is the lowest "measurable” analyte Concentration by a specified method. By improving our technologies, we are also lowering the detection level for nearly all methods.

A Detection Limit is the lowest Concentration of a chemical that can reliably be distinguished from a zero concentration.

A detector (sensor) is a transducer whose purpose is to sense (that is, to detect) some characteristic of its environs. It detects events or changes in quantities and provides a corresponding output, generally as an electrical or optical signal; for example, a thermocouple converts temperature to an output voltage.
