多氯联苯在两种海洋微藻中毒性效应及富集效应的研究
A study of toxicity and bioaccumulation of PCBs in two spe-cies of marine microalgae
摘要
Abstract
In order to investigate the toxicity effects of PCBs on marine microalgae, two algae species, Chaetoceros muelleri and Platymonas subcordiformis, were selected to study the effects of PCB138 on growth and SOD enzyme activities. Meanwhile, the enrichment effects of PCB138 on C. muelleri and P. subcordiformis were analyzed by gas chromatography. The results showed that PCB138 had obvious toxicity effects on the growth of C. muelleri and P. subcordiformis. The 96-h EC50 of PCB138 on C. muelleri and P. subcordiformis were 0.057 mg·L–1 and 0.354 mg·L–1, respectively, which indicated that C. muelleri showed more sensitivity and poorer tolerance to PCB138 than P. sub-cordiformis. SOD activities in two microalgae cells were greatly induced by low levels of PCB138, and reduced as the PCB138 concentrations increased above threshold values. Both of the algae species had strong capabilities to accumulate PCB138. The adsorption amount of PCB138 in C. muelleri increased with increasing cultivation time, while the amount of PCB138 adsorbed in P. subcordiformis first increased, then decreased.关键词
