This is dependent upon the process in which it is used, the dosage of the chemical, its partitioning characteristics, the oil (or condensate) and water production at the platform, the in-process degradation mechanisms and the residence time before release. As the name suggests, the Predicted No Effect Concentration (PNEC) is an estimate of the highest concentration of a chemical in a particular environmental compartment at which no adverse effects are expected. It is, thus, an estimate of the sensitivity of the ecosystem to a certain chemical.

3. Difficulties of resolving data-set requirements for pure substances and preparations (a preparation being a combination of two or more substances). 4. Restricting development of CHARM to hazard assessment, when the original concept was to include risk assessment also. The software development was abandoned and was replaced by an EOSCA funded initiative to develop a simple EXCEL based spreadsheet. The confidentiality issues are still of concern, especially regarding the publishing of the calculated Hazard Quotient (HQ) values.
