摘要
利用“Ｙ”形回避槽，进行了中国对虾（ Ｐｅｎａｅｕｓ ｃｈｉｎｅｎｓｉｓ） 对Ｐｂ 、Ｃｒ、Ｚｎ 及其混 合物的回避反应实验。计算得出中国对虾对Ｐｂ 、Ｃｒ、Ｚｎ 的５０ ％ 回避率浓度分别为１１ ．４、３３．２ 、和２３８．１ｍｇ／Ｌ。对虾对Ｐｂ － Ｃｒ 及Ｐｂ － Ｚｎ 混合液的回避反应呈相加作用，但当混合液浓度为０．５ 毒性单位Ｐｂ加０ ．５ 毒性单位Ｚｎ 时，回避反应呈协同作用。
ABSTRACT Study on the avoidance response of Penaeus chinensis to heavy metals(Pb、Cr、Zn) and heavy metal mixture (PbCr, PbZn) was carried out using a Ymodel avoidance apparatus. The concentrations calculated to induce 50% avoidance rate by Penaeus chinensis were 11.4、33.2 and 238.1mg/L for Pb、Cr and Zn, respectively. Mixtures of PbCr and PbZn produced additive effect in the avoidance test using Penaeus chinensis. But when the mixed Pb-Zn solution had 0.5 toxic unit Pb and 0.5 toxic unit Zn, the mixture seemed to have synergistic effect.
