For existing chemicals, we should always consider ________ exposure assessment based on modelling, to derive an environmental concentration.

For existing chemicals, we should always consider ________ exposure assessment based on modelling, to derive an environmental concentration. Correct Answer Reasonable worst case

After reasonable worst case exposure, the subsequent step is to estimate the substance’s release rate based upon its use pattern. All potential emission sources are analysed from production and formulation to use and disposal, and the receiving environmental compartment(s) is/are identified.

The concentration of oxygen at the inner surface of the vessel is maintained at a level C depending on the pressure in the vessel, while the concentration at the outer surface is reduced to zero by the escape of oxygen to the surroundings.
