  1. The main study in this paper included as follows : the content and distribution of heavy metals in sediments and benthic organisms from the sewage stream in guangzhou city ; the acute toxicity and joint toxicity of mercury and selenium to swordtail fish ( xiphophorus helleri ) ; the damage of mercury to the indexes of antioxidant system in the gills and livers in swordtail ( including the measurement of the activities of total antioxidative capacity [ t ~ aoc ], superoxide dismutase [ sod ], glutathione peroxidase [ gsh - px ] and the concentration of malondiald - ehyde [ mda ] ) and the relief effects of selenium on it, as well as the physiological damage of mercury on the tissues, namely : the antagonistic effect of na + - k + ~ atpase activity on the tissues between selenite and mercury, and the ultrastructural damage under the exposure of mercury

    研究內容主要有：廣州市河涌沉積物及底棲生物體內重金屬含量及評價；汞和硒對劍尾魚的急性毒性和聯合毒性及安全濃度的評價；汞對劍尾魚鰓和肝臟中抗氧化系統的毒性，包括對總抗氧化能力、超氧化物歧化酶、谷胱甘肽過氧化物酶活力及丙二醛含量的測定及硒對其保護作用；汞對劍尾魚組織生理毒性即：汞對na ~ + - k ~ + atpase活力的影響及硒的保護作用和汞和對劍尾魚組織超微結構的損傷等。以高氯酸?硝酸消化法和火焰原子吸收分光光度法測定了廣州市河涌沉積物和底棲生物中重金屬含量。
  2. From this result it can be concluded that the est isoenzyme was very sensitivity for the toxication of hg24 and can be used as a bioindicator of the environmental pollution. the same experiment had been done twice in 2003. scetion : from october in 2002 to october in 2003, by using random amplified polymorphic dna ( rapd ), the effects on ovary ' s dna under different concentration of mercury in freshwater crab ( sinopotamon yangtsekiense ) were detected for the first time

    汞對長江華溪蟹卵巢總dna的影響汞對長江華溪蟹（ sinopot胭onyangtsekiense ）細胞及分子水平的影響以體外暴露的方法，對經汞體外暴露一周長江華溪蟹的卵巢總dna ，採用隨機引物擴增多態性dna （ rapd ）技術對13條隨機引物的擴增圖譜用nei共享度公式進行分析。
  3. Testing of materials for semiconductor technology ; determination of the dopant concentration profile of single crystalline semiconductor material by means of the capacitancevoltage method and mercury contact

    半導體技術材料的試驗.用電容-電壓法和水銀接點確定
  4. Among them, mercury was accumulated strongly in the gill, followed by the heart, hepatopancreas and gonad. the bioaccumulation of hg2 + in s. yangtsekiense had the concentration - effect relationship, that was to say, the more the concentration increased, the more the bioaccumulation increased. at the high mercury concentration, there was more obvious the time - effect relationship being observed

    結果表明：汞在蟹體內的積累具有一定的選擇性，其總的生物積累量由高到低的順序為鰓心臟肝胰腺性腺，並且積累量有著一定的濃度?效應關系；在高濃度汞處理下，其積累量還具有一定的時間?效應關系。
  5. Air quality - stationary source emissions - manual method of determination of the concentration of total mercury

    空氣質量.固定源排放.所有汞濃度測定的人工方法
  6. The highest concentration of mercury was found in the antennal glands by mass spectrum analysis

    質譜分析表明，觸角腺中汞的含量最高。
  7. 10. the results of the study showed that predatory fish, such as shark, tuna and swordfish, had the highest concentration of mercury while seafood other than fish, particularly shellfish, was identified as the main dietary source of cadmium and inorganic arsenic

    10 .是次研究結果顯示，捕獵魚類，如鯊魚金槍魚和劍魚的含汞量最高。此外， "魚類以外的海產"尤其是貝介類被視為是鎘及無機砷的主要來源。
