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 ...
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 ...
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 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]
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.

Studying dose response, and developing dose–response models, is central to determining "safe", "hazardous" and (where relevant) beneficial levels and dosages for drugs, pollutants, foods, and other substances to which humans or other organisms are exposed.
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).
