The predicted no-effect concentration (PNEC) is the concentration of a chemical which marks the limit at which below no adverse effects of exposure in an ecosystem are measured. PNEC values are intended to be conservative and predict the concentration at which a chemical will likely have no toxic effect. They are not intended to predict the ...
An Measured Environmental Concentration (MEC) relates to a chemical substance found in an environmental sample. The concentration of the compound may result from direct contamination, transformation and/or metabolization of a different chemical contaminant, natural origin or a combination of these sources.
The PNEC was shifted to its present location in 1982 and commissioned as PNS Jauhar as an independent unit of Pakistan Navy. In 1995, Pakistan Parliament passed legislation to rename the school as "Pakistan Navy Engineering College (PNEC)", making the school a constituent college of National University of Sciences and Technology, Pakistan (NUST ...
The derived no-effect level (DNEL) is the level of exposure to a substance above which humans should not be exposed.The REACH regulation defines them as exposure levels beneath which a substance does not harm human health. [1]
Calculated value of a chemical in the environment on the basis of exposure models such as the European Union System for the Evaluation of Substances (EUSES). Used in the context of Chemical Safety Assessments (CSA) and referenced in Chemical Safety Reports (CSR).

Current Protocols is a series of laboratory manuals for life scientists. The first title, Current Protocols in Molecular Biology, was established in 1987 by the founding editors Frederick M. Ausubel, Roger Brent, Robert Kingston, David Moore, Jon Seidman, Kevin Struhl, and John A. Smith of the Massachusetts General Hospital Department of Molecular Biology and the Harvard Medical School ...
The distance from the mean is measured in standard deviations. It is named after Stanley Levey and E. R. Jennings, pathologists who suggested in 1950 that Shewhart's individuals control chart could be used in the clinical laboratory. [5] The date and time, or more often the number of the control run, is plotted on the x-axis.
