The acute toxicity of aldehyde (HCHO), sodium hypochlorite (NaClO), calcium hypochlorite \[Ca(ClO)\-2\], malachite green (C\-\{23\}H\-\{25\}N\-2Cl), iodine (I\-2) to \%M. mongolica\% and \%B. plicatilis\% was determined. The 24 h LC\-\{50\} and 48 h LC\-\{50\} to \%M. mongolica\% and their 95% confide interval were: aldehyde (HCHO), 115 50(77 81-171 83) mg/L and 73 58(51 14-88 72) mg/L; sodium hypochlority(NaClO),0 74(0 58-0 94) mg/L and 0 38(0 31-0 47) mg/L; calcium hypochlority\[Ca(ClO)\-2\],0 67(0 55-0 83) mg/L and 0 58(0 48-0 71)mg/L;iodine(I\-2),0 348(0 303-0 398) mg/L and 0 27(0 22-0 32) \{mg/L\};malachite green (C\-\{23\}H\-\{25\}N\-2Cl),0 97(0 69-1 26) mg/L and 0 37(0 25-0 54) mg/L. The 24 IC\-\{50\} and 48 h IC\-\{50\} to \%B.plicatilis\% were: formaldehyde, 10 86(9 00-13 08) mg/L and 2 98(2 391-3 711) mg/L;sodium hypochlorite, 0 87(0 67-1 11) mg/L and 0 39(0 13-0 46) mg/L;sodium hypochlorite,0 78(0 59-1 05) mg/L and 0 55(0 47-0 64) mg/L;iodine,0 41(0 26-0 63) mg/L and 0 09(0 055-0 141) mg/L;malachite green,0 84(0 64-1 11) mg/L and 0 23(0 21-0 26) mg/L, respectively.
