作者对地面水中不同浓度的环丁砜进行了系统实验研究与现场调查。结果表明,环丁砜对水臭觉的实际阈浓度为10.6mg/L,对水的生化需氧过程无明显抑制作用,慢性毒性阈剂量为2.5mg/kg,最大无作用剂量为0.25mg/kg,无诱变性,280mg/kg无致畸性。据此,作者建议地面水中环丁砜的最高容许浓度为5mg/L,结合现场调查,认为该浓度是安全可行的。 The authors conducted a systematic experimental study and field investigation on different concentrations of sulfolane in surface water. The results showed that the actual threshold concentration of sulfolane to water odors was 10.6mg / L, which had no significant inhibitory effect on the biochemical oxygen demand of water. The threshold dose of chronic toxicity was 2.5mg / kg and the maximum non-action dose was 0.25mg / kg. No mutagenicity, 280mg / kg No teratogenicity. Accordingly, the authors suggest that the maximum allowable concentration of sulfolane in surface water is 5mg / L, which is considered safe and feasible in combination with the field investigation.
