    總體而言，雌性大鼠對硒、汞毒性的拮抗作用與雄性大鼠相比時更為敏感；相同性別的大鼠體內，聯合高劑量時硒、汞的拮抗作用最明顯，聯合中劑量時，拮抗效果相對不明顯，而聯合低劑量時，拮抗效果最差；聯合摩爾劑量比為2 ： 1 （ se ： hg ）和汞的積累濃度大於100nmol g ，是大鼠體內大部分組織器官（肝臟、胸腺、脾、胃、肺）中四川大學碩士學位論文硒、汞等摩爾比積累的兩個必要條件，同時也是硒、汞的相互作用產生最佳桔抗效果的兩個重要前提。
  4. It meaned that simulated acid rain made the toxic effects of zn or cd on growth of the plants more serious. the fresh weights and chlorophyll contents of phaseolus vulgaris l were the highest when ph value of acid rain was 4. 5, zn concentration was 60 mg / kg, and or cd concentration was 0. 5 mg / kg. this showed that lower acidity of simulated acid rain and lower concentrations of zn or cd could promote growth of the plants

    本試驗中，酸雨加zn或者酸雨加cd使小白菜鮮重小於單一污染處理，說明酸雨增加了zn 、 cd對小白菜的毒害作用；而當酸雨ph值為4 . 5 、 zn濃度為20mg / kg或cd濃度為0 . 5mg / kg時，四季豆鮮重達到最大值，這表明低強度的酸雨和低濃度的zn 、 cd促進四季豆的生長。
