Abstract
采用水质安全在线生物预警系统(BEWs)记录行为强度数据,探讨了2种环境污染物Cd2+和2,4,6-TCP联合胁迫下,不同暴露浓度、不同暴露时间日本青鳉的行为响应。在不同浓度比例的农药暴露中,10,5,1和0.1TU的暴露浓度下的平均行为反应时间分别为3.9,7.2,28.2和43.6h。结果表明,在2种污染物的暴露下,日本青鳉的逐级行为响应既受化合物浓度高低的影响,又受暴露时间的影响,但每个浓度的不同配比之间的行为响应时间差异不明显,而且每个浓度2种污染物不同配比暴露下日本青鳉的逐级行为响应基本一致。日本青鳉对Cd2+污染的行为反应具有明显的滞后性,即由于毒性累积作用,Cd2+对日本青鳉产生的环境胁迫小于相同浓度的2,4,6-TCP。
