Poiycyclic aromatic hydrocarbons ( pah ) are priority trace organic pollutants in the clrtap ( convention on long - range transboundary air poliution ) pops ( persistent organic poilutants ) protocol. both laboratory experiments and fie1d surveys unequivocally demonstrated that pah adversely affect estuarine and marine organisms. pah are implicated in the development of iesions and tumors in fish, they produce biochemical disruptions and cell damage that iead to mutations, developmental malformations and cancel although many marine organisms do not exhibit acute responses to pah " exposure, but suffer sublethal effects
本論文以湄洲灣海域和廈門西海域養殖區為研究區域,採用現代分析技術,從分子水平上系統研究了多環芳烴( pah )在海水、沉積物、養殖魚類中的含量分佈:通過現場實驗,實驗室暫養、投毒和恢復實驗系統測定了養殖魚類的肝臟、膽汁、鰓、全血等不同器官、組織的生化指標及養殖魚類肝臟、膽汁的化學指標,探討了這些指標對水環境多環芳烴污染的生物指示作用。( 3 ) pah " levels in maricultural site tvere much higher than that in the adjacent non - maricultural site, and it showed that mariculture was one of the contributors of marine pah " pollution in seal atef. 2 western xiamen harbort ( 1 ) pah " levels in surface seat " ater and sediment of the survey site " ere quite severe
5系統研究了鱸魚、真鯛體內不同器官、組織的生化指標? ?過氧化氫酶( cat ) 、超氧化物歧化酶( sod ) 、脂質過氧化( lpo )指標,結合水體及生物樣的pah污染分析結果,探討了這些指標對水環境pah污染的指示作用。2. the results showed that the contents of cach - extractable soil p, and soil test phosphorus ( olsen, bray, mehlich - 3 ) and algae - available p contents ( naoh - extractable soil p ) in the soils correlated significantly with the contents of ortho - p, particulate p and bioavailable p in runoff, respectively, which were feasible to be used as primary indices to evaluate of agriculture p impacting on surface water quality. the results also showed that the relationships between the phosphorus sorption of soil index ( psi ), and the degree of soil saturation with phosphorus ( dpss ) and the contents of ortho - p, particulate p and bioavailable p in runoff reached significant level, respectively
黃壤旱地土壤易解吸磷( cacl _ 2 - p ) 、土壤有效磷( olsen - p 、 bray - p 、 mehlich - 3 - p )或藻類可以利用的土壤磷( naoh - p )與地表徑流中顆粒態磷、生物有效性磷和磷酸根態磷之間均存在顯著的相關性,在一定的程度上可用cacl _ 2 - p 、 olsen - p作為指示黃壤旱地地表徑流中磷潛在流失的預警指標,來判斷旱地存在磷素非點源污染的可能性。Meanwhile, according to the assessment cell of small watershed, the paper evaluates each index and compositive index. the paper can provide scientific bases for both protection and use of wetland by disclosing the spatial distributing rules and analyzing the impact on environment brought because of exploiting. the study shows that 1 ) in the structure of wetland ecosystem health of panjin city in 2000, better area accounts for 22 %, generic area 52 %, worse area 26 % ; 2 ) in shuangtaizi national wetland nature reserve, the health of many regions is better, the one of partial regions is threaten, the area of wetland is decreasing ; 3 ) in the period from 1986 to 2000, paddy field, shrimp and crab pool were increased, swamp and biodiversity were decreased gradually, and the environment of wetland was polluted gradually
本文以生態系統學、景觀生態學、生態系統健康、區域可持續發展等理論為基礎,根據聯合國經濟合作開發署提出的壓力-狀態-響應( psr )框架模型,以遙感數據及統計監測數據為基礎,採用rs 、 gis 、 gps技術,結合數理統計和數學模型方法,提取土地利用/土地覆蓋信息、濕地類型信息、小流域信息、濕地景觀指數、濕地初級生產力、濕地人口壓力指數、濕地蓄水量、濕地污染物負荷、濕地變化等數據,建立盤錦市濕地生態系統健康數據庫,以小流域為評價單元,對每個小流域濕地進行單因子和綜合評價,揭示盤錦市濕地生態系統健康狀況的空間分佈規律,同時對濕地資源開發造成的環境影響進行剖析,為濕地資源的保護與利用提供科學依據。At the same time, the result of the functional diversity of soil microbial community indicated that soil microbial metabolism quotient ( awcd ), microbial community richness and shannon index all decreased significantly in red soils polluted by cadmium and lead compared with non - polluted soils. these results suggested the structure of microbial community have changed, decreased the functional diversity of microbial community, and reduced the microbial number utilizing different carbon resources
Biologgn測試結果顯示,鎘、鉛污染紅壤微生物群落代謝剖面( awcd )及群落豐富度、多樣性指數均顯著低於非污染土壤,表明重金屬污染引起了土壤微生物群落功能多樣性下降,減少了能利用有關碳源底物的微生物數量、降低了微生中義摘要物對單一碳源底物的利用能力,最終導致土壤微生物群落功能多樣性發生變化。Phytoplankton was dominated by diatom and blue - green algae according to density and by diatom in light of biomass
