Notes:

*1 The number only includes tetrachloroethylene sold as pure for subsequent mixing by the user. Tetrachloroethylene, which is mixed with other buthanol by the suppliers, is included under preparations.

*2 The net import is reported stabile while the consumption for the major applications is reduced. This indicates, that a considerable amount of tetrachlorethylen can not be accounted for in detail.

*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.
