汞積累 的英文怎麼說
中文拼音 [gǒngjīlěi]
汞積累
英文
mercury accumulation-
Exploring the possible mechanisms is an important content of bioinorganic chemistry and ecotoxicology, which has signality in modifying contamination effect to animals. this thesis studies on the chemical speciation of mercury and selenium in dolphin livers, sub - chronic toxic effect of wistar rats of sodium selenite and mercuric chloride and investigates the antagonism mechanism from there aspects : 1. redistribution of mercury in the presence of selenium, 2
本文以海豚肝臟為對象，研究其積累的高濃度汞硒化合物的化學形態和結構，並結合動物實驗的研究，從汞硒相互作用的總體生物學表現，汞硒在動物體內分佈變化和結合形態的變化以及汞硒化合物的結構等方面探討兩元素毒性拮抗作用機理。Section : laboratory experiment was carried out to determine mercury accumulation in four organs that were gills, heart, hepatopancreas and gonad of freshwater crab sinopotamon yangtsekiense by using atomic absorption method
汞在長江華溪蟹四種器官的積累以體外暴露的方式，採用還原氣化原子吸收的方法，測定了長江華溪蟹鰓、心臟、肝胰腺和性腺中汞的積累情況。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。This correlation exists not only between different organs but also in the same organ. the mol - ratio of selenium and mercury is about 1 : 1 in liver, gland, spleen, stomach and lungs when selenium and mercury were administered simultaneously with 2 : 1 mol - ratio, especially in stomach. and female rats have the higher probability of 1 : 1 mol - ratio accumulation of selenium and mercury than male ones
本文首次報道了除肝臟和腎臟外，大鼠心臟、大腦、胸腺、肺、脾、胃、肌肉、睪丸等組織之間及同一組織內，汞與硒含量呈高度的正相關性；當硒、汞聯合高劑量組注入大鼠體內時，肝臟、胸腺、脾、胃、肺等組織中硒、汞以大約1 ： 1摩爾比的特徵積累，尤其在大鼠的胃中，硒、汞的積累方式更容易表現為1 ： 1摩爾比的形式；同時，雌性大鼠體內硒、汞以1 ： 1摩爾比形式積累的幾率比雄性大鼠為大。The distribution and accumulation of three kinds of heavy metals including lead, copper and mercury in tissues and cells of several organs, and their effects on activity of digestive enzymes and alkaline phosphatase of macrobrachium nipponense were studied with light microscopy, transmission electron microscopy, cytochemical method, atom absorption spectrum, mass spectrum analysis and enzyme analytical method
本文應用組織學、組織化學、透射電鏡、原子吸收光譜分析和酶學分析等方法，研究了鉛、銅、汞等三種重金屬在日本沼蝦各主要器官細胞內的分佈和積累以及對日本沼蝦消化酶和堿性磷酸酶活性的影響。Among the joint dose experiments, the antagonism of selenium and mercury is the most evident in the rats with 2 : 1 mol - ratio of selenium and mercury but the least in the rats with 1 : 2 mol - ratio of selenium and mercury. the results also showed that there are two essential conditions for good antagonistic effect of selenium and mercury and 1 : 1 mol - ratio relationship of selenium and mercury in the most organs ( liver, gland, spleen, stomach and lungs ). one is that the content of mercury is more than 100nmol / g, and another is the 2 : 1 dose ratio of selenium and mercury
總體而言，雌性大鼠對硒、汞毒性的拮抗作用與雄性大鼠相比時更為敏感；相同性別的大鼠體內，聯合高劑量時硒、汞的拮抗作用最明顯，聯合中劑量時，拮抗效果相對不明顯，而聯合低劑量時，拮抗效果最差；聯合摩爾劑量比為2 ： 1 （ se ： hg ）和汞的積累濃度大於100nmol g ，是大鼠體內大部分組織器官（肝臟、胸腺、脾、胃、肺）中四川大學碩士學位論文硒、汞等摩爾比積累的兩個必要條件，同時也是硒、汞的相互作用產生最佳桔抗效果的兩個重要前提。The concentrations of mercury and selenium in ten dolphin livers were determined. mercury and selenium exist in the livers as abnomal high concentrations at approximate 1 : 1 molar ratio of mercury to selenium
10個肝臟樣品汞硒含量測定結果表明，海豚肝臟中同時積累了高濃度的汞和硒（ r = 0 . 87 ） 。分享友人
