...內，人類進食受 污染貝類便有可能出現中毒症候。常見的貝類中毒包括可致命的神經紊亂麻痺性貝類中毒、引致腸 胃不適的下痢性貝類中毒、引致腸胃不適和神經紊亂的神經性貝類中毒，以及引致腸胃及神經系統 失調的失憶性貝類中毒，嚴重者可能致命。 只有少數藻類曾導致大量野生和養殖魚類死亡。魚類透過直接攝入受污染水體中的毒素或食物鏈造 成生物積聚，均可能中毒死亡。此外藻類毒素亦會刺激魚鰓製造大量黏液，或直接堵塞魚鰓妨礙吸 氧，令魚類窒息而死。大規模和高濃度的藻華會耗盡環境中的養份，令微藻下沉，細菌分解微藻導 致底層氧氣枯竭，水中含氧量低於每公升 2 毫克時會出現低氧現象，當水中的含氧量接近零時便會 出現缺氧。由...

...香港水域的海豚個體，共有十五隻於 2018 年不見所蹤，但其中四隻卻在伶仃 7 洋出現。國內水域的持續監察及珠江口中華白海豚的合作研究有助進一步了解牠 們於整個區域的空間動態。於大嶼山西面及西南面調查區之間、及於大嶼山西北 面及西面調查區之間移動的個別海豚，其數量亦於近數年持續下降。 在過去三個監察報告中發現的本港水域內的海豚使用模式有所改變，亦再次 透過分析個別海豚活動範圍而顯示出來。59 隻屬北大嶼山社群的海豚當中，44 隻個體曾將部份及整個活動範圍由大嶼山北面水域轉移至西面及西南面水域，但 於 2017 及 2018 年，卻有 29 隻個體的活動範圍轉移出現逆轉，牠們並再次回到 大嶼山北面...
