| Abstract: | Heavy metal pollution is becoming more and more serious in marine environment recently.In order to evaluate the impact of heavy metals on marine eco-environment,the biotoxicity of heavy metals to marine algae was investigated.Using batch culture method,acute toxicity of Hg(Ⅱ) and Pb(Ⅱ) to 8 species of marine unicellular algae,Heterosigma akashiwo Hada,Chaetoceros curvisetus Cleve,Prorocentrum micans Ehrenberg,Gymnodinium sp.,Skeletonema costatum(Greville) Cleve,Phaeodactylum tricornutum Bohlin,Platymonas helgolanidica and Platymonas subcordiformis,was measured.The results showed that the 96 h-EC50 of Hg(Ⅱ) for the tested algal species were 16,42,24,37,31,12,385 and 161 μg·L-1,respectively;and the 96 h-EC50 of Pb(Ⅱ) for Heterosigma akashiwo,Chaetoceros curvisetus,Prorocentrum micans and Gymnodinium sp.were 9 516,8 373,12 002 and 10 128 μg·L-1,respectively.The toxicity of Hg(Ⅱ) was significantly higher than that of Pb(Ⅱ) under the f/2 culture condition;the ratios of 96 h-EC50 values of Pb(Ⅱ) to Hg(Ⅱ) for Heterosigma akashiwo,Chaetoceros curvisetus,Prorocentrum micans and Gymnodinium sp.were 594.75,199.36,500.08 and 273.73,respectively.However,the 96 h-EC50 of Pb(Ⅱ) for Skeletonema costatum,Phaeodactylum tricornutum,Platymonas helgolanidica and Platymonas subcordiformis could not be detected accurately in the effective concentration range under the f/2 culture condition,which suggested that the toxicity of Pb(Ⅱ) to these four algae was very low.Based on the value of 96 h-EC50,the tolerance of feed algae to heavy metals was estimated to be higher than that of harmful bloom algae.Moreover,it is found that Pb(Ⅱ) could stimulate the growth of algae at relatively lower concentration,and the tolerance of algae to heavy metal was higher under the f/2 culture condition than that in natural environment. |
