March 22, 2018. ln one European country, registered permethrin products also include capsule suspensions and lacquer formulations (Papadopoulou-Mourkidou, 1983; Swaine & Tandy, 1984; The Royal Society of Chemistry, 1986, 1989; Meister, 1990). It would also not be expected to persist in soil or water systems. ;���Z��T�����$�AvF��^EzA�V��aU�����i%��TOw�&�zU9:$|���V �M�U6[{�Ԍ��V�f�3̍����}s3�(���y�K�o��g]��mQ��5��r����&�IϪ�5��g�M�VlY��L'1/A�R�3}�������#���[ۗ֎�2��8�.��f"҃�q��T=��,P��u��\�0$A���eH0:rF���Cce0F�����*Ѕ4R�I˥Ne�!+y��`���:9�~�����WR ���ӽ�KȲx�Y�k��O&�B�XȜޯ$tF� ����I ��1���)6pń9�ӷ�Um뱈I٨��Ҵ�}��w�V�6 l]���8s�8h�w���犎nr�۠?5��p�,j�1�=]�'G��������r\~�����ޢ��5��s-�t<5N�N;\S�ٚ|ξv�$����Ct���, database match) = 6.50 Exper. & documentation regarding permethrin, etc.: the results of one study near estuarine areas showed that permethrin persist...
