Relative resistance to mediate (0.01−0.40 mg/l) concentration is explained by adaptation to toxic natural amines, which are contained in the surface water bodies in the same limits. Obtained results can serve as a basis to review established MPC (maximal permissible concentration) of PA-14 (0.003 mg/l) and methodology of MPC calculation on the whole. %8 2011-09-27
