The comparative fates and effects of salicylic acid (SA) and Na salicylate in algae (Scenedesmus subspicatus, Monoraphidium minutum), in Lemna minor, and in Daphnia magna were examined. Test methods were principally based on the OECD testing guidelines with modifications in the procedures. The influence of fulvic acid (FA) on bioconcentration and on toxic effects was studied. FA addition significantly reduced the bioavailability of SA in L. minor and the algae species. SA was more toxic to Lemnaceae, algae, and daphnids than to its Na salt. Bioconcentration factors in S. subspicatus, M. minutum, and L. minor were about 10(3) in 72-96 hr. The reproducibility of D. magna was reduced by 38% at a concentration of 20 mg SA/liter.
研究了水杨酸(SA)和水杨酸钠在藻类(近尖栅藻、微小单歧藻)、浮萍和大型溞中的相对归宿和效应。测试方法主要基于经合组织测试指南,并对程序进行了修改。研究了富里酸(FA)对生物富集和毒性效应的影响。添加FA显著降低了SA在浮萍和藻类物种中的生物可利用性。SA对浮萍科植物、藻类和水蚤的毒性比对其钠盐的毒性更大。在72 - 96小时内,近尖栅藻、微小单歧藻和浮萍中的生物富集系数约为10³。在20毫克SA/升的浓度下,大型溞的繁殖能力降低了38%。
