Potential for internal loading by phosphorus based on sequential extraction of surficial sediment in a shallow Egyptian Lake 总被引:1,自引:0,他引:1
Maha Ahmed Mohamed Abdallah 《Environmental monitoring and assessment》2011,178(1-4):203-212
The fractionation of phosphorus (P) in shallow Lake Maryout surficial sediments was investigated in order to understand its potential availability in relation to the eutrophication status of this lake. The rank order of P fractions was NaOH-P > HCl-P > NH4Cl-P > BD-P. The metal oxide-bound P (NaOH-P) averaged 43% in this hypereutrophic lake and would be potentially available under low oxygen conditions. The highly available, loosely sorbed P (NH4Cl-P) represented 20% of the sedimentary inorganic P on average, while the reductant P (BD-P) averaged 15% and is also considered highly available under low oxygen conditions. The less available calcium-bound P (HCl-P) represented 22% of sedimentary inorganic P. Lake Maryout exhibits high potential for release of P from sediment in forms available to algae, which is undesirable for eutrophication control. The range of potentially available P in tested sediments was 1,541 to 3,990 mg/kg (ppm), a very high quantity capable of supporting algal blooms independent of external loading. 相似文献

In the context of renewed interest in collaboration in natural resource management,the collaborative governance approach has lately been introduced to the forest Protected Areas(PAs)in Bangladesh.The adoption of this co-management approach is seen as an attempt to influence the governance process towards a transformation from the conventional custodian system to a more participatory management regime.Recognition of rights and responsibilities,effective participation,and equitable distribution of benefits amongst the key stakeholders working under a facilitative policy and legal framework are believed to address the broader goals of sustainable development Notwithstanding the resurgence of interest in governance of forest PAs through the co-management approach,academic research on the subject remains limited.This article attempts to review selected key information and milestones on the forest PAs governance with special reference to the major policies and legal documents.With a brief introductory section,this article focuses on the genesis and selected major features of the Forest PAs in the country.The discussion then dwells on the policy and legal framework and provides a critique on its relevance for promoting community participation.The existing institutional arrangements for community engagement in protected area governance are also analyzed in light of the national and international commitment and policy obligations on the part of the country.The salient observations and key findings of the study include the following:(1)despite its limitations,comanagement as concept and practice has gradually taken roots in Bangladesh;(2)the degree and level of active community participation remain low and limited,and there is also clear weakness in conscientizing and orientating the local community on the key legal and policy issues related to PA governance in the country;and(3)policy makers,practitioners,and other local stakeholders related to PA governance need to be oriented on international commitment and national de 相似文献
