Description
  • A mass budget study of major in-lake Al fluxes, palaeolimnological data on a >10,000 years old sediment record, and photochemical experiments performed at Plešné Lake (Czech Republic) suggest that photochemical liberation of organically-bound aluminium (Al) and iron (Fe) by solar radiation is a significant natural source of their ionic species for lakes and subsequent oxyhydroxides for sediments. The results show that photo-chemically induced transformation of dissolved Al and Fe to solid oxyhydroxides deposited to Plešné Lake sediment dominated (91 and 73%, respectively) their sedimentary flux throughout the pre-industrial era, since soil formation in the catchment. We hypothesise that the same Al and Fe transporting process occurs in other lakes and coastal marine areas and is ecologically important because Al and Fe oxyhydroxides can bind trace metals and phosphorus.

  • Látková bilance hlavních toků Al, paleolimnologický rozbor sedimentů (stáří 0 až >10000 let) a fotochemické experimenty v Plešném jezeře (Česká republika) ukazují, že fotochemické uvolňování Al a Fe z organických komplexů slunečním zářením je významným přírodním zdrojem jejich iontových forem pro jezerní vodu a následně (po hydrolýze a vysrážení) i zdrojem jejich hydroxidů pro sedimenty. Výsledky ukazují, že fotochemická transformace rozpuštěného Al a Fe na pevné hydroxidy byla jejich hlavním zdrojem pro sediment (91% pro Al a 73% pro Fe) během preindustriálního období, v podstatě od okamžiku tvorby půd v povodí. Předpokládáme, že podobný transportní mechanismus probíhá i v ostatních jezerech a pobřežních mořích a je ekologicky významný, protože hydroxidy Al a Fe mohou poutat a imobilizovat další kovy a fosfor.
