  1. Using cd, cu, zn and cr as experimental toxicants and crucian as experimental creature, we employed the environmental biotechniques ( flame atomic absorption spectrophotometry, the method of improved pyrogallol autoxidation and electron microscopy ) to study the acute toxicity and secure concentrations of heavy metals to crucian ; the accumulation and distribution of mixed heavy metals to fingling crucian ; the activities of superoxide dismutase ( sod ) of gill and liver tissues and the hispathological and ultrastructural change of superfine structure of liver and kidney of crucian after cadmium exposure. through which, we intended to fully and systemically study the toxic influence of heavy metals to fish, and preliminarily discuss the influence of heavy metals pollution to the diversified level of fish such as individual, organ, tissue, cell and molecule. thus we tried to provide scientific evidence to establish preventative management measures, avoid and relieve the harm of heavy metals pollution to aquicolous ecosystem in time

    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。
  3. The variety of the activity of na + / k + - atpase, ca2 + - atpase and sod by increase calcium concentration in the water, and the effects of cd2 +, estradiol - 17 and ca2 + on the lymphocyte proliferation from blood and head kidney of ctenopharyngodon idellus were also investigated the significance of this paper is that to research the toxicity of cadmium to the fish and to search the mechanism of the cadmium toxicity to the fish. and the protection of calcium on cd2 + toxicity

    本論文研究了鎘對草魚的毒性作用,比較了在不同鈣濃度條件下,其鰓、肝臟、腦等組織中sod 、 na ~ + k ~ + ? atp酶、 ca ~ ( 2 + ) ? atp酶的活性變化規律以及鎘和17 ?雌二醇對草魚血液及頭腎淋巴細胞增殖的影響,評價鎘對魚類的毒害作用,探索鎘的毒害機理。
