Eutrophication is a process resulting from an increase in anthropogenic nutrient inputs from rivers and other sources, the consequences of which can include enhanced algal biomass, changes in plankton community composition and oxygen depletion near the seabed. Within the context of the Marine Strategy Framework Directive, indicators (and associated threshold) have been identified to assess the ...

the zerebar lake is a shallow freshwater lake located in the northwestern iran. the lake is surrounded by three human activities: agriculture, tourism and dam. the present study aimed to investigate (1) which human activity has the greatest impact on eutrophication of the zerebar lake (2) if phytoplankton communities, as the indicator, are correlated with the human activities. water samples wer...

The semi-enclosed topography and the strong anthropogenic pressures make the Baltic Sea vulnerable to environmentally induced ecological changes. The large-scale nutrient overenrichment is one of the most serious threats against the health and future perspectives of the Baltic Sea ecosystem. To combat the eutrophication in a complex marine ecosystem, an interdisciplinary agenda is needed. Co-op...

Soil phosphorus (P) fertility arising from historic P inputs is a major driver of P mobilisation in agricultural runoff and increases the risk of aquatic eutrophication. To determine the environmental benefit of lowering soil P fertility, a meta-analysis of the relationship between soil test P (measured as Olsen-P) and P concentrations in agricultural drainflow and surface runoff in mostly UK s...

Over the last 20 years, loss of seagrass beds, often related with increased eutrophication, became a common problem worldwide. In the Mondego estuary (Portugal), eutrophication has triggered serious biological changes, which led to an overall increase in primary production and to a progressive replacement of seagrass Zostera noltii beds by coarser sediments and opportunistic macroalgae. The eff...

Reuse of treated wastewater for irrigation purposes is a measure to reduce water stress and overexploitation freshwater resources. This study aims investigate the environmental economic impacts current conventional treatment plant (WWTP) in Peschiera Borromeo (Milan, Italy), compare possible scenarios enable reclaimed reuse agriculture. Accordingly, we propose alternative disinfection methods (...

In this paper a comparative study of two measurement campaigns carried out in Barcelona, Spain, and Pozna , Poland, to identify spectrum occupancy in different bands, is presented. In both cases the measurement setup was harmonized to obtain comparable results. The problem of efficient noise floor estimation was also considered and a pragmatic approach that takes into account both internal and ...

Major advances in the scientific understanding and management of eutrophication have been made since the late 1960s. The control of point sources of phosphorus reduced algal blooms in many lakes. Diffuse nutrient sources from land use changes and urbanization in the catchments of lakes have proved possible to control but require many years of restoration efforts. The importance of water residen...

Riedinger-Whitmore, M.A., T.J. Whitmore, J.M. Smoak, M. Brenner, A. Moore, J. Curtis and C.L. Schelske. 2005. Cyanobacterial proliferation is a recent response to eutrophication in many Florida lakes: A paleolimnological assessment. Lake and Reserv. Manage. 21(4):423-435. Cyanobacteria dominate many highly productive Florida lakes. Algal proliferation often is attributed to eutrophication durin...
