environmental toxicity 解釋
環境毒性
  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

    隨后以這幾種重金屬作為實驗毒物，以鯽魚為實驗動物，應用環境生物技術、火焰原子吸收分光光度法、鄰苯三酚自氧化法、透射電鏡等技術研究了重金屬cu 、 zn 、 cd和cr對鯽魚的急性毒性及其安全濃度評價、混合重金屬在鯽魚幼體組織內的積累和分佈、 cd對鯽魚鰓和肝臟中sod活性的影響、 cd對鯽魚肝細胞和腎細胞超微結構的影響等，全面和系統地研究了水環境中重金屬暴露對魚類的毒性影響，初步探討了重金屬污染對魚類的個體? ?器官? ?組織? ?細胞? ?分子等各水平層次的影響，為制定漁業生產上預防性的管理措施提供科學依據，及時避免或減輕重金屬污染對水生生態系統造成的損害。
  2. The results suggested that monocrotophos had not only environmental estrogen effects, but also reproductive toxicity. monocrotophos could destroy the membrane systems of three kinds of pituitary secretary cell, spermatogenous cell and sperm. in three kinds of pituitary secretary cell, nuclear membrane and endoplasmic reticulum showed dilation, and endoplasmic reticulum even exhibited fusion under exposure in high concentration

    久效磷對精原細胞的損傷最為嚴重，細胞膜和核膜水腫，高濃度暴露組的細胞膜和核膜溶解，線粒體的崎也有溶解現象;但久效磷對精母細胞和精子細胞的損傷並不明顯，主要表現為膜系統的輕微水腫。
  3. But the previous research works mainly focused on the screening of environment persistent pollutants, such as organochlorine insecticides and alkylphenol, to our knowledge, no report on the residual toxicity and environmental estrogens effects has been existed in the literature yet

    但目前為止，主要集中於環境中持久性有機污染物如有機氯農藥和烷基酚類化合物的篩選上，而我國是農業大國，大量地使用了有機磷農藥，其殘留毒性及環境雌激素效應的研究還尚未見報道。
  4. The physi - chemical properties of the aluminum, in environmental and physical conditions, are the determinants of its bioavailability and toxicity. aluminum absorption and its metabolic kinetics depend on the properties of al - organics complex to a large extent

    鋁的物理化學形態，即暴露的媒介以及生物體的器官中的形態，常常是該元素的生物利用度和毒性的決定因素，鋁的吸收和生物代謝動力學在很大程度上依靠與不同配體形成的絡合物的性質。
  5. The company, with green environmental protection as its objective and the promotion of agriculture through science and technology innovation as its responsibility, aims at carrying scientific research and development and providing high - efficiency, low - toxicity, low - residual and low pollution agricultural chemicals

    公司以「綠色環保」為宗旨、以「科技興農」為已任，提供高效、低毒、低殘留、低污染、環保安全的先進農藥產品的市場推廣和植保服務。
  6. At last, several suggestions are proposed : to design a new formula without public hazards ; to preform a toxicity eliminating design for existing toxic slurries ; to give the measures of implementing green chemical grouting including the respects of technique, equipment and environmental protection ; and to point several kinds of grouting matinals to be unsuitably used or carefully used, and to quick improve the techniques of prepolymerization and post - processing

    提出了按無公害要求設計新配方，對有毒害漿材進行去毒害改性設計，並通過採取工藝改造、設備更新、安全防護等措施來實現綠色化學灌漿的諸多辦法，並對不提倡用、應慎用和應改進預聚及后處理工藝的漿材品種提出了改進建議。
