and relevant data and using the CLEA model, just as the
Environment Agency calculates SGVs. SGVs are in fact GAC derived and published by the environment agency. For example, a range of GACs for more complex chemicals has been calculated and been made publicly available by charity
1140:, with input from a range of authoritative sources including the Environment Agency. That said, GACs are not always openly published, as deriving them is a complex matter and thus these values do hold commercial value for consultancies who have undertaken such calculations.
1178:
SGVs and GACs derived from these scenarios may only be used if the scenarios apply exactly or otherwise it is clearly demonstrated that the scenarios are more conservative than the real-world situation. For example, in the case of a

where the critical receptor is a working female adult aged 16–65 years old and exposed for a working lifetime of 49 years for 45 hours per week.
