Rahman, Laboratory culture experiments to study the effect of lignite humic acid fractions on iron solubility and iron uptake rates in phytoplankton AbstractThe major fractions of dissolved iron in seawater exist as a complex with organic ligands. A high bioavailability of iron bound to humic acid (HA) compared to the other model ligands, such as desferrioxamine B or ferrichrome, has been reported, which implies the importance of HA to control the geochemical behavior and the transfer of Fe to marine phytoplankton, particularly in estuarine and coastal waters. In the current work, the effect of different HAfractions (>100, 100-30, 30-10, 10-5, and 5-3 kDa), which are extracted from lignite, on the comparative solubility of iron in seawater and the corresponding influence on the iron-uptake and growth rate of the phytoplankton (Prymnesium parvum) has been studied using laboratory cultures. The lower molecular weight (MW) HA fractions, such as 30-10, 10-5 and 5-3 kDa, remained soluble in the simulated seawater medium for a longer time-span compared to the higher MW fractions. The lower MW fractions facilitated higher iron solubility and assisted in achieving a better phytoplankton growth rate. However, a reciprocal impact on phytoplankton growth rates has been observed when the HA concentration increased to a higher range (0.18 to 18 mg-C L -1 ). The highest intracellular Fe uptake in phytoplankton occurred with 30-10 kDa HA in seawater, and the extracellular dissolved Fe concentrations were higher for smaller-sized HA fractions. In a nutshell, our study showed that the controlled addition of lower MW fractions of HA (up to 30-10 kDa) in estuarine waters could ensure the accelerated uptake of Fe in phytoplankton as well as a better growth rate.

“…Probably the most attractive way is the use of lignite as sources for humic acids in agriculture (Kučerík et al 2003) or for the production of organic, organomineral fertilizers (generally coal-based fertilizers) and soil conditioners (Chassapis et al 2009;Song and Schobert 1996;Pehlivan and Arslan 2007). The simplest and cheapest way is the direct application of natural lignite after milling to suitable particle sizes by spreading or ploughing.…”

“…For example, a product from South Moravian lignite called Terra Clean acts as an effective soil conditioner and it is exported to some Arab countries (Honěk et al 2009). One drawback of these applications can be related to the release of inorganic and organic components into the soil, surface and underground water as a consequence of the interaction of lignite with water (Chassapis et al 2009). The available literature pays sufficient attention to inorganic materials (especially toxic elements such as lead, arsenic, copper, cadmium, etc.)…”

Study of water-extractable fractions from South Moravian lignite

International audienceLignite can be applied directly in natural form on agricultural fields as a soil conditioner. However, there is little information on leaching of risky compounds by its interaction with water. South Moravian lignite was therefore extracted with water at 25 A degrees C and 2.3 % of water-soluble fractions were obtained from lignite corresponding to 0.3 % of total organic carbon. All ten fractions form aromatic and aliphatic structures with oxygen-containing functional groups such as carboxyl groups, alcohols, ethers, esters, can be characterized as fulvic-like and humic-like substances. According to the XPS spectra, the fractions contain two nitrogen forms, one of which is ascribed to pyrroles and the second is related to protonated amines or quaternary nitrogen. Analysis at molecular level showed that the fractions contain compounds such as benzene carboxylic acids and their derivatives, small aliphatic diacids, fatty acids and polyols. Most of the identified molecules reflect clearly the presence of microbial remains in the lignite structure since microbial activity during coalification is well known. The differences between the individual fractions are negligible, especially after 21 days of extraction. From environmental point of view, it seems that the identified compounds do not represent a toxic risk
