中文摘要：

2011年夏季，我国秦皇岛沿岸海域再次暴发了大面积的微微型浮游植物抑食金球藻褐潮。为了弄清该藻的毒性以及评估其对人们生命健康的影响，本实验以卤虫作为受试生物，在室内条件下测试了该褐潮水体对卤虫的急性毒性及卤虫对该藻的摄食作用，并以室内纯种培养的抑食金球藻对小白兔进行急性皮肤刺激和眼刺激实验，对小白鼠进行急性经口毒性实验。结果表明，抑食金球藻褐潮水体对卤虫无急性毒性，卤虫能以抑食金球藻为食，摄食率随着摄食藻密度的升高而上升。抑食金球藻藻液对实验兔的皮肤和眼睛无明显刺激作用，对小白鼠无急性毒性作用。该藻暴发褐潮时，对人们的生命健康安全影响较小。

英文摘要：

In summer of 2011, harmful algae bloom （ HAB ） caused by picoplanktonic alga Aureococcus anophagefferens broke out again along the coast of Qinhuangdao Island, China. In order to understand the toxicity and the impact on human health, acute toxicity of the bloom water against Artemia sinica and the feeding rate of A. sinica on A. anophagefferens were studied under laboratory conditions. Stimulation effects of A. anophagefferens monoclonal culture on skins and eyes of rabbits were also studied. In addition, acute oral toxicity tests were carried out on mice. The results showed that the bloom water has no impact on the survival of A. sinica within 48 h. A. sinica could feed on A. anophagefferens, and the feeding rate increased with cell density of A. anophagefferens. The highest feeding rate of A. sinica within 8 h was up to 3 287 cells/ind/h. A. anophagefferens had no discernible effect on rabbits＇ skins and eyes,and also had no effect on mice. It is relatively safe for people working or swimming in the sea during the A. anophagefferens bloom.
