Eutrophication control: the shift to invasive methods managing the internal nutrient loads. A bibliometric analysis

Nowadays severe causes of environmental depletion among water sources are related to excessive disposal of phosphorus and nitrogen nutrients at aqueous environments and subsequently the dominant phenomenon of eutrophication reported via visible cyanobacterial or algal blooms, surface scums, floating plant materials, and benthic macrophyte aggregations. Such environmental pollution problems are also deteriorating by fish kills in aqueous environments, being primarily caused by oxygen shortage and the release of toxic substances. In this research context remediation techniques are directed to control surface runoff to lakes while simultaneously widening riparian buffer zones and constructing wetlands on the main inflow. In this context our study has been developed to gain a deeper insight into eutrophication-related control methods through deploying combined bibliometrics of eutrophication control. These bibliometric analyses have been considered as a credible tool to predict and assess the research history of multidisciplinary scientific topics of local and global academia interest and socio-economic impact. In this respect the bibliometric analysis of our study explored the disciplines of eutrophication control research and lake restoration methods, while identifying the current trends that should abide to environmental remediation. Moreover, our study has jointly identified a wide spectrum of key-aspects of polluted water sources, including internal nutrient loads, water quality, lake restoration methods, sediment capping materials, P inactivation agents and phosphate removal. It was concluded that sediment capping materials, dredging, hypolimnetic aeration, they can jointly approach the theoretical coverage of eutrophication control at related web-search publications, while it can be denoted that no previous bibliometric analyses to date performed keywords-based bibliometric analysis in terms of internal nutrient loads regarding lake res toration.
