Abstract The publication is a synthetic collection of information on the sorption properties of marine and freshwater algae. Kinetics and sorption equilibrium of heavy metals in algae-solution system, influence of abiotic factors on the process of sorption and desorption of analytes from biomass are discussed. In paper the results of laboratory tests conducted using different species and types of algae, which purpose was to assess their usefulness as natural sorbents, are described. The conclusions drawn from current research confirm the results from literature.

The Impact

Abstract Due to their occurrence in very different conditions and high resistance to physical and chemical factors, algae are pioneers colonising new environments and their sorption properties are used in biomonitoring and water remediation. The efficiency of the process of heavy metal sorption in algae used for in situ tests depends on abiotic factors, such as the chemical composition of water. Freshwater algae Spirogyra sp. were used in tests. Algae were exposed in the laboratory in manganese chloride solutions with various contents of other cations, including heavy metals and macronutrients. It has been shown that some heavy metals may desorb manganese bound to the surface of algae as a result of ion exchange in the following sequence: Cd2+ < Mn2+ ≈ Zn2+ < Cu2+. It has been also found that the competitiveness of sorption of cations naturally present in the alga environment versus Mn2+ cations changes in the sequence Na+ < Ca2+ < H+, defined for the concentrations referring to the cation unit charge. The results of tests were compared to the results of dried sea algae Palmaria palmata analyses.

Traditional Knowledge System

Abstract This study presents the case of an original and traditional knowledge system of palung, which is used in salt-making in the coastal communities of Bali. The study emphasizes the practicalities of the system and its epistemology using anthropological and sociological methods. It is known that the traditional knowledge system of palung salt production has been preserved through the generations as a form of local wisdom. This traditional knowledge system emphasizes the use of local natural resources in accordance with the coastal ecosystems of Bali, where the cultivation of extracted soil (tanah sari), sand, bamboo, and coconut trees is carried out manually. This study has evidenced that the palung process successfully produces salt of excellent taste and quality. Based on laboratory tests conducted on palung salt samples, the results show that it does not contain any heavy metals and that it has good nutritional content. Because of its use of available natural resources, this traditional knowledge system is sustainable and environmentally friendly.

AbstractAn anthropic ecosystem from Romania was investigated from acarological, vegetation and chemical point of view. The community structures of two groups of mites were studied (Acari: Mesostigmata, Oribatida) from a tailing pond, using transect method, in correlation with concentrations of heavy metals (As, Cu, Pb, Ni, Mn and Zn), with abiotic factors (altitude, aspect, soil temperature, soil humidity, soil pH) and biotic factor (vegetation coverage). Taking into account the mite communities, in total, 30 mite species were identified, with 1009 individuals and 18 immatures (10 species with 59 individuals, 5 immatures of Mesostigmata and 20 species with 950 individuals, 13 immatures of Oribatida). The investigated habitats from the tailing pond were grouped in five transects, with different degree of pollution, based on total metal loads. Taking into account of the connection between mites communities, abiotic factors and heavy metals, each transect were characterized through specific relationship. Using multivariate statistical analysis, we revealed that the occurrence of some Oribatida species was strongly correlated with vegetation coverage, soil pH and soil humidity, though concentrations of Cu, As, Mn, Ni and Zn also had an influence. Pb and Zn concentrations were shown to influence the occurrence of Mesostigmata mites. The heterogeneity of mites species richness at 2 m2 scale was correlated with a metric related to the heterogeneity of heavy metals at the same scale.

Abstract The publication is a synthetic review of many years of research on the possibility of using water plants (macrophytes) to assess pollution of surface waters and the possibility of using the biomass in phytoremediation processes. The results of the research of kinetics and equilibria of heavy metals sorption and desorption conditions were presented in order to repeatedly use the biomass, as well as the research on the influence of abiotic factors on sorption processes. Defence mechanisms of macrophytes, which enable them to vegetate in considerably polluted waters, have been discussed. The results presented herein and carried out in many countries demonstrate that macrophytes can be successfully used in the biomonitoring of water environments and phytoremediation of waters and sewage; however, validation of these procedures requires more detailed research of the mechanisms, which accompany them.
