表面活性物质(C_(12)H_(12)F_(14)O_5-N_4S)广泛用于国民经济各部门。它易溶于水、可以随工厂排放污水进入水体,因此对它的最高容许浓度必须有科学的依据。本文报道(以下简称ОМ)对水的一般卫生学状况和急、慢性毒性实验结果。乙二酰胺的起泡沫阈浓度,在20℃时为500mg/l、60℃时为250mg/l。臭阈分别为1740和781mg/l。ОМ5和10mg/l抑制生物氧耗,降低硝化过程。急性毒性试验用100只大鼠和100只
Surface-active substances (C_ (12) H_ (12) F_ (14) O_5-N_4S) are widely used in all sectors of the national economy. It is soluble in water and can be discharged into the body of water with the factory effluent, so the maximum allowable concentration for it must be scientifically based. This article reports (ОМ) on the general hygiene of water and acute and chronic toxicity test results. The oxaamide foaming threshold concentration is 500 mg / l at 20 ° C and 250 mg / l at 60 ° C. Odor thresholds were 1740 and 781 mg / l, respectively. ОМ5 and 10mg / l inhibit biological oxygen consumption, reducing the nitrification process. Acute toxicity test with 100 rats and 100
