藻类的

A total of 19 algal genera were indentified, including 2 genera of Cyanophyceae、6 genera of Chlorophyceae, 9 genera of Bacillariophyceae、2 genera of Euglenophyceae. In Apirl, the dominant algal genus of the east-southern water gate and the southern new Plant 7 were Oscillatoria. In the other two months, the dominant algal genera of the three sample sites were diatoms.

在四月份东南水门与南7新厂主要优势藻属是颤藻属，其他月份与地点皆以矽藻为主，所以结果显示麦寮大排以矽藻为主要优势族群，以七月份含量最高时可占七月份总藻类数的91.6％左右。

It is shown from the assessment results that (1) both the TN and TP fluxes discharged from the Changjiang River to the Changjiang River estuary sea area increased continuedly, the DIN concentration in the sea areas increased continuedly, and the Si concentration decreased continuedly, which resulted in the significant changes in N/P/Si ratios;(2) the chlorophyll a concentration in the sea areas increased continuedly, and the significant changes in community structure of phytoplankton occurred;(3) the species and biomass of benthos declined greatly, and the bottom oxygen-poor water area increased significantly;(4) the range and occurrence frequency of red tide events in the sea areas increased greatly, and the algal toxic infection events of mussel were frequently found in the sea areas.

结果表明，长江向长江口海域输送总氮和总磷通量持续增大，长江口及其邻近海域无机氮浓度持续增高而硅浓度持续下降，并由此导致N/P/Si与比值的显著变化；该海域叶绿素a浓度持续增大，浮游植物群落结构也发生了显著变化；该海域底栖生物种类和生物量都大大减少，底层水低氧区面积也显著扩大；该海域赤潮事件无论是规模还是频率都大大增加，藻类毒素DSP/PSP贻贝传染事件也时有发生。

The results showed that the toxicity of brofluthrinate to birds, bees and earthworms is low, to fish is medium, and to Daphnia, alga, silkworms is high.

结果表明：其对鸟类、蜜蜂和蚯蚓的毒性较低；对鱼类属中等毒性；对B045类、藻类和家蚕属高毒性。

Younger Dryas is characterised by increased dinocyst influx and Operculodinium cetrocarpum content.O.cetrocarpum assemblage should be indicative of the cool and nutrient surface seawater,different from Spiniferites spp.assemblage or Protoperidinioid cyst assemblage reflecting respectively warm and cold sea-surface conditions.

通过92个样品分析，发现南海北部陆坡末次冰期以来沉积物中有机壁浮游藻类输入通量在新仙女木期和早全新世明显高于其它时期，新仙女木期的输入通量峰值及不同于Spiniferites spp。
