英文摘要Single and Joint toxic effects of polycyclic musks including 1 3 4 6 7 8-hexahydro-4 6 6 7,8,8-hexamethylcyclopenta[g]-2-benzopyran (HHCB) and 7-acetyl 1,1 3 4 4,6-hexamethyl-1,2 3,4 tetrahydronapthalene (AHTN) and cadmium (Cd) on seed germination and seedling growth of wheat (Triticum aestivum) were investigated The results showed that the toxicity sequence of HHCB toxic to wheat seed germination and seedling growth was similar to that of AHTN that is germination rate > shoot elongation > root elongation, while the toxicity of Cd was in the sequence of root elongation > shoot elongation > germination rate according to the LC(50) and EC(50) values It is suggested that polycyclic musks and Cd had different toxicological mechanisms Root and shoot elongation of wheat might be good bioindicators for the contamination of polycyclic musks and Cd in soil The mixture of polycyclic musks and Cd had synergistic effects on T aestivum according to the equi-toxic mixture approach when root elongation was selected as the toxicological endpoint Thus the Joint toxicity of HHCB and Cd was significantly higher than the single toxicity of HHCB or Cd which was also confirmed by the EC(50 mix) value of the mixture (EC(50) (mix) = 0 530 TU(mix)) The EC(50) (mix) value of the mixture of AHTN and Cd was 0 614 TU(mix) which indicated that the mixture toxicity was strengthened when AHTN coexisted with Cd
