The Red Tide Organism Chaetoceros sp. Responding to Exposure to Oil and Dispersant

Laboratory experiments were conducted to study the effects of oil spills and dispersants on growth red tide organism Chaetoceros sp. Crude produced from Chinese Bohai Sea, diesel oil, chemical dispersant (GM-2) in China added into cultures. The results showed that both crude could enhance Data analyzed by one-way ANOVA, confidence interval was 95%.
