| 摘 要： | 以1,4-二氯苯(1,4-DCB)处理后,角毛藻Chaetoceros mulleri的生长状况,藻体细胞的形态改变,及角毛藻中对1,4-DCB的富集能力,来检测1,4-DCB对海洋微藻的毒性效应.结果表明:1,4-DCB对角毛藻的生长有一定抑制作用,该效应表现出一定的质量浓度和时间依赖性;1,4-DCB处理后,角毛藻细胞能明显富集1,4-DCB,该富集能力与环境中1,4-DCB的质量浓度有关;而且角毛藻藻细胞形态受到1,4-DCB的损伤.这表明1,4-DCB污染后能在角毛藻细胞内富集并对其产生细胞毒害效应,且受有机物污染后藻类作为饵料的价值降低.

| Abstract: | Toxic effects of 1,4-dichlorobenzene(1,4-DCB) on Chaetoceros mulleri were studied through the changes of growth and the cellular morphological changes of Chaetoceros mulleri, even the bioconcentration contents of 1,4-DCB in Chaetoceros mulleri. The results showed the growth of Chaetoceros mulleri was inhibited by the 1,4-DCB in treated time-response and dose-response manners. There were bioconcentration effects in Chaetoceros mulleri treated by 1,4-DCB, and cellular morphology of Chaetoceros mulleri was changed by 1,4 - DCB. The results suggested that the pollution of 1,2-DCB affected the growth of Chaetoceros mulleri-was and decreased the values of Chaetoceros mulleri as the feedstuff. |
