“…No significant correlations were observed between Fe and TP (Table 2), which could be explained by two potential phenomena: Blocking of part of sediment iron in the iron sulfide form, as well as a partial transition of mobile pool of P, bound to Fe and Mn compounds into Al-P form. Rydin [30] as well as Welch et al [17] suggest that mobile P fractions with elapsed time are replaced by Al-P fraction. In the Starodworskie Lake a share of Al-P fraction in the mineral P in 2016 year was higher comparing to 1994, 1995, and 1996 years.…”

“…In addition, the active substance forms so-called "active layer", which theoretically should continue to adsorb phosphorus on the available adsorption surface. This limits an internal loading phenomenon [9,13,14,16,17,23].…”

“…One of the most popular methods is phosphorus inactivation via using preparations, which remove the P excess from water, and then block P in bottom deposits. The alum (hydrated aluminum sulfate Al 2 (SO 4 ) 3 •18 H 2 O) was among the earliest used compounds for this purpose [9,11,[13][14][15][16][17]. Starodworskie Lake was the first lake in Poland, in which the alum was used for P inactivation.…”

Lake restoration is a part of geoengineering, which is a useful tool for landscape management. The phosphorus inactivation method is one of the most popular lake restoration methods. Using chemical compounds for P binding is leading to the creation of sediment “active layer”, which should show higher P adsorption abilities, compared to non-modified sediment. Howewer, it provides rather little information, how long the modified sediment remains active, and whether it is effective in continuous P binding. Lake meromixis is not commonly observed phenomenon, and sediment located in monimolimnion area is subjected long term anoxia. Therefore, observation of “active layer” in a meromictic lake can give very important data about durability of restoration effects. The object of our study was meromictic Starodworskie Lake (5.57 ha, max. depth 24.5 m), located in Olsztyn Lakeland, Poland. In the past the analyzed lake was subjected to various restoration methods, and phosphorus inactivation method by alum use (1994–1995) was the last used treatment type. The mixing regime of this lake had changed from bradimictic (before and during restoration time) into durable meromictic (post-restoration period). The research made two decades after implementing of P inactivation showed the presence of “active” sediment layer 10–15 cm below sediment surface. This sediment layer showed much higher content of P bound to aluminum, compared to surficial sediment layer. P binding molar ratio was assessed and amounted to 16.1 straightly after restoration and 6.1 after 21 years. This fraction amounts were higher that the values noted before restoration (ca. 358% higher than in 1994 and during restoration (ca. 86% higher than in 1995), which was probably the effect of continuous phosphorus adsorption by “active layer” in post-restoration period.

“…Grand Lake Saint Marys study site Grand Lake St. Marys (GLSM) is a reservoir located in western Ohio and is utilized for recreation, boating, fishing, and swimming. It has a mean depth of 1.6 m, a surface area of 5,000 ha, it is hypereutrophic, and has a long East to West wind fetch of 16 km (Figure 1; Welch et al, 2017). GLSM is known for its large blooms of Anabaena, Aphanizomenon, Microcystis, and Planktothrix with summer chlorophyll and total phosphorus (TP) averaging >100 μg L −1 (Hoorman et al, 2008;Filbrun et al, 2013;Steffen et al, 2014;Welch et al, 2017).…”

Frontiers is more than just an open access publisher of scholarly articles: it is a pioneering approach to the world of academia, radically improving the way scholarly research is managed. The grand vision of Frontiers is a world where all people have an equal opportunity to seek, share and generate knowledge. Frontiers provides immediate and permanent online open access to all its publications, but this alone is not enough to realize our grand goals. Frontiers journal seriesThe Frontiers journal series is a multi-tier and interdisciplinary set of openaccess, online journals, promising a paradigm shift from the current review, selection and dissemination processes in academic publishing. All Frontiers journals are driven by researchers for researchers; therefore, they constitute a service to the scholarly community. At the same time, the Frontiers journal series operates on a revolutionary invention, the tiered publishing system, initially addressing specific communities of scholars, and gradually climbing up to broader public understanding, thus serving the interests of the lay society, too. Dedication to qualityEach Frontiers article is a landmark of the highest quality, thanks to genuinely collaborative interactions between authors and review editors, who include some of the world's best academicians. Research must be certified by peers before entering a stream of knowledge that may eventually reach the public -and shape society; therefore, Frontiers only applies the most rigorous and unbiased reviews. Frontiers revolutionizes research publishing by freely delivering the most outstanding research, evaluated with no bias from both the academic and social point of view. By applying the most advanced information technologies, Frontiers is catapulting scholarly publishing into a new generation. What are Frontiers Research Topics?Frontiers Research Topics are very popular trademarks of the Frontiers journals series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area.
