during tests in the field, persists in soil for more than one year, or
during laboratory tests, forms non-extractable residues in amounts exceeding 70 % of the initial dose after 100 days with a mineralisation rate of less than 5 % in 100 days,
has unacceptable consequences or effects on non-target organisms,
unless it is scientifically demonstrated that under field conditions there is no unacceptable accumulation in soil.
