Paradigm for Substance Flow Analyses

Appendix 2

Approximate Man-hour Inputs

In the table below the input of man-hours for the core SFA and optional extensions is summarised. The proposed inputs should be considered as reference values, and the actual input has to be determined specifically for each substance in question.

 

Core SFA, detailed

Approximately 3-5 man months per substance.

For 'sun-down chemicals' extra input must be expected if the consumption assessment are to reach the level of a detailed analysis.

Core SFA, overview

Approximately 1 man-month per substance if more substances are analysed in the same project.

International market and trends in consumption, detailed

Approximately 1-3 man-week per substance or substance group.

The use of international market analyses reports should be specified in the budget. The cost of these reports are 10,000-30,000 DKK.

Qualitative description of the exposure of man by use and disposal of finished products

Approximately 1-4 man-week per substance.

Scenarios for future emissions and loss of the substance, simple "business as usual" model

The input will depend on the number of application areas covered by the scenarios. It should be noted that each application area might cover many product types with different life-time distributions. It is estimated that the simple scenarios will approximately take in total three to six man-weeks for all application areas dependent on the number of different product types.

Scenarios for future emissions and loss of the substance, detailed model

The input will depend on the number of application areas covered by the scenarios. It should be noted that each application area might cover many product types with different life-time distributions. It is estimated that the detailed scenarios will approximately take one to four man-weeks for the first application area dependent on the number of different product types, and less for the subsequent application areas.

Occurrence and fate in the environment

The input for this appendix will be very dependent on whether the SFA covers a single element or a large group of chemicals. If the SFA covers a large group of chemicals it may be most appropriate to report this assessment in a separate publication. The input for a single substance will approximately be a half to two man-month.

National and international regulation on the use of the substance

Approximately between a half and one man-week per substance.

Assessment of substitutes

The input will be dependent on the number of applications and levels covered by the assessment. The input for an assessment at all levels for one application will approximately be one to three man-weeks.

Recycling, downcycling and material deterioration

The input will be dependent on the number of application areas covered. By the initiation of the SFA is should be defined which application areas are covered by the appendix. There is only very limited experience with this extension in SFAs and the input has to be estimated separately for each substance.

The specification of focus areas is estimated not to influence the total budget, as inputs are allocated from one area to another.
