Details of the new threshold values or classifications proposed are listed in the blue pages (appendix, page I). The Commission has adopted these proposals but puts them up for discussion until 31.12.2005. New data or scientific commentary may be submitted to the Commission's scientific office (Kommissionssekretariat) until this date. This information will be examined and taken into consideration in the final ratification.
