摘要
蚯蚓是土壤生态的重要指示生物。试验用3种方法研究了2种含砷兽药洛克沙胂(roxarsone)和阿散酸(arsanilicacid)对安德爱胜蚓(Eiseniaandrei)的急性毒性。结果表明,人工土壤法、人造土壤法和自然土壤法测得的洛克沙胂和阿散酸对蚯蚓的LC50分别为每千克土壤3.23、2.99、3.56g和5.80、5.10、6.80g。2种含砷兽药对蚯蚓的毒性都较低。
Earthworms are the important biological indicator for soil ecosystem.The acute toxicity test of two veterinary pharmaceuticals containing arsenic-roxarsone and arsanilic acid to earthworms(Eisenia Andrei) was studied using three methods.The LC_ 50 of roxarsone and arsanilic acid to earth worms using artificial soil test,arsol test,natural soil test were 3.23,2.99,3.45 g·(kg dry soil) -1 and 5.80,5.10,6.80 g·(kg dry soil) -1 respectively.The toxicity of these two veterinary pharmaceuticals to earthworms was low.
