Tabel 2.4.

Estimated consumption and losses of dichloromethane in Denmark.

Notes:

*1 Double counting of the consumption of preparations manufactured in Denmark is eliminated in the totals (paint stripper, sealer, glues, cleaning agents). Products for which the country of manufacturing is unknown are considered imported (deemed most likely).

*2 An additional 70-90 tons/year are used for Danish manufacturing of products for export (sealers for diecasting of plastics).

*3 Indirect exposure via evaporation to air and subsequent rainfalls are not included.

*4 Totals are rounded up.

*5 Recycling numbers does not include internal recycling integrated in manufacturing processes.

*6 The presented figures are rough estimates based on general knowledge on chemical characteristics and standard routines of use and disposal in the application fields in question.

*7 Part of this loss to air is caused by the danish production of ancillaries for export.
