An ERD (Entity Relationship Diagram) is a graphical representation of the data in rest within a system (e.g. a business, an organization, an application) that is subject to analysis.
The U.S. EPA established the Reference Dose (RfD) Work Group to address these concerns. In preparing this report, the RfD Work Group has drawn on traditional report on risk assessment (NRC, 1983), to more fully articulate the use of noncancer, nonmutagenic experimental data in reaching regulatory decisions about the significance of exposures to chemicals.
From Wikipedia, the free encyclopedia. RFQ is the initialism for a number of things: 1  Radio Frequency Quadrupole, a particular setup of electrodes used as a mass analyzer or an element of a linear accelerator.  Regulatory Focus Questionnaire, a questionnaire designed to measure prevention focus and promotion focus.
