  1. It can also restrain the decomposition of organic substances in the soil and the bind of nitrogen, and wash away the nutritious elements, such as magnesium, calcium, and potassium. the acid rain deprives the soil. it acidifies the rivers and lakes, and dissolves the heavy metal in the soil into water, therefore poisons the fish

    它可以直接使大片森林死亡，農作物枯萎；也會抑制土壤中有機物的分解和氮的固定，淋洗與土壤粒子結合的鈣、鎂、鉀等營養元素，使土壤貧瘠化；還可使湖泊、河流酸化，並溶解土壤和水體底泥中的重金屬進入水中，毒害魚類；加速建築物和文物古跡的腐蝕和風化過程；可能危及人體健康。
  2. 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。

  8. As the agricultural nfs is the most important factor for water environmental deterioration and lake eutrophication in china, more and more scientists and technologists focus on the control countermeasurc and pollution mechanism of agricultural non - point source ( nfs ). based on the investigation of natural resource and agricultural distribution, the loss rule of nitrogen and phosphorus in the typical land of qiandao lake watershed and distribution rule of the phytoplankton and physico - chemical characteristic in the lake were studied, and the input loading of nitrogen and phosphorus was also calculated by the annagnps model in this thesis. according to the routine monitoring data of the water environment in qiandao lake from 1989 to 2001, the concentrations of toxic substance and heavy metal were under the monitoring limit, but the total nitrogen ( tn ) and total phosphorus ( tp ) were much higher than the criterion for lake and reservoir

    本文調查了千島湖流域的自然資源和農業生產情況，研究了典型坡地降雨徑流中的氮、磷污染物的輸出規律，利用annagnps模型估算流域農業非點源污染物輸入負荷，並在千島湖內設點采樣，對水質理化指標和浮游植物群落進行系統的研究，得出以下結論： 1989 2001年間的水環境常規監測資料統計分析表明，有毒物質和重金屬濃度長期在監測下限內， no _ 2 - n 、 no _ 3 - n 、 nh _ 3 - n年平均濃度均符合類標準，但湖泊水庫特定項目tn和tp濃度分別為超類和類，呈嚴重超標狀況，湖區主要污染因子是將導致富營養化的物質tn和tp 。
