The aim of the presented research was to examine the concentration of biogenic compounds and heavy metals in the bottom sediments of the Sulejów Reservoir (Central Poland) from October 2018. Based on the obtained research results, maps of the spatial distribution were prepared. The following parameters were analyzed: total phosphorus (TP), total Kjeldahl nitrogen, total organic carbon (TOC), ratio of total organic carbon to nitrogen (C:N), organic matter content as well as Cd, Cr and Pb concentrations. The sediments were collected at 28 sampling sites, covering the whole area of the reservoir. The differences in the content of individual biogenic compounds result from the composition of the debris applied by the supplying rivers, as well as the content of this elements in the water, long retention time (40 days) and depth from which the tested sediments were taken. The distribution of examined compounds was largely influenced by the agricultural activity in the studied area, as well as the presence of ports and recreational points. Based on the measurements, the highest amounts of biogenic components deposit in sediments of deep parts in slow-flowing waters, in stagnation zones, areas adjacent to arable land, and the sites where fine-size fractions prevail in the deposited material. Biogenic compounds in sediments of the Sulejów Reservoir showed a pattern of gradual increase along the reservoir from lower values in the back-water part. A similar relationship is visible for heavy metals. Referring to the ecotoxicological criteria, it can be stated that bottom sediments from the Sulejów Reservoir collected in 2018 are not toxicologically contaminated in terms of cadmium, lead and chromium content.

Water Catchment

Water bodies of river-lake systems can act as barriers in the movement of nutrients and toxic heavy metals outside their water catchment area. These components can be suspended in the water column, deposited in bottom sediments or bioaccumulated by the vegetation in the water body. A constant exchange of substances takes place between bottom sediments and macrophytes. The composition of bottom sediments and their distribution affects the intensity of nutrients and metals assimilation by macrophytes in the river-lake systems. The aim of research was to analyse the effect of bottom sediments on the nutrients and metal content in macrophytes. It was demonstrated that tissues of plants anchored in sediments that were more abundant in nutrients had higher contents of biogenic components and heavy metals. The properties of bottom sediments, mainly their granulometric composition, but also organic matter content and pH, determine the content of biogenes and heavy metals in macrophytes to a significant extent. On the other hand, it was demonstrated that aquatic plants could affect the grain size in the sediments. Macrophytes and sediments of river-lake systems play a very important role in reducing the transport of nutrients outside the area of the system, through capturing and incorporating them into the tissues of aquatic plants.

A survey of cooperative concentrated rubber latex industry in southern Thailand showed that most of them do not have adequate treatments for their wastes. Especially, skim latex serum (SS) with high source of ammonia is a main wastewater generated from their industries and concentrated latex sludge (CS) with high source of phosphorus is a main solid waste obtained from their industries. It was noted that both of the wastes cause environment problems. Water pollution and bad smell of NH3from these waste systems have also been generated and affected to human health. One low investment possibility is the elaboration of these wastes by composting because these wastes contain some nutrients (N, P, K) in available forms resulting in high potential to add value for fertilizer production. However, both of the wastes have a small amount of organic matter content that need to be mixed with other materials with high organic matter such as sawdust (SD). Thus, the aim of this research was to investigate the utilization of these wastes to produce compost. In this work, the SS, CS and SD were composted in specially designed composting vessel (6L) with various mixing ratios of the SS, CS and SD in order to examine the optimized mixing condition and physical properties of the compost. Each treatment was composted with 60 days of composting duration. The performance of composting process was analyzed in term of the following: temperature, pH, electric conductivity, total organic carbon, total nitrogen, total phosphorus and C/N ratio. The analysis of temperature, pH, and electric conductivity was measured every day while the analysis of total organic carbon, total nitrogen, total phosphorus and C/N ratio was investigated every 10 days. According to the results, the optimized mixing ratio of SS, CS and SD for composting was 1:1:1. The final resultant compost was feasible for agricultural use. From the view point of compost qualities, it was in the range of the Thai compost standard with 7.91 of pH, 15.06 (%w/w) of total organic carbon, 1.24 (%w/w) of total nitrogen, 0.69 (%w/w) of total phosphorus and 21.6 of C/N ratio.

The study of heavy metal speciation in bottom sediments of the Vyshnevolotsky water reservoir is presented in this paper. Sequential selective procedure was used to determine the heavy metal speciation in bottom sediments and thermodynamic calculation — to determine ones in interstitial water. It has been shown that Mn are mainly presented in exchangeable and carbonate forms; for Fe, Zn, Pb и Co the forms are related to iron and manganese hydroxides is played an important role; and Cu and Ni are mainly associated with organic matter. In interstitial waters the main forms of heavy metal speciation are free ions for Zn, Ni, Co and Cd, carbonate complexes for Pb, fulvate complexes for Cu. Effects of particle size and organic matter content in sediments on distribution of mobile and potentially mobile forms of toxic elements have been revealed.

Chemical composition of leaves of Sonneratia apetala Buch.-Ham. collected from three islands (chars) representing three hydrological regimes in a segment of the coastal zone of Bangladesh was studied. Their relations to some soil chemical and physical variables have also been investigated. The results showed that concentrations of B, C, Fe, Ga, Li, Mg, Mn, N, Na, P, Zn and Sr in leaves of S. apetala grown in different islands differed significantly. It was also revealed that some heavy metals, viz. Mn, Fe, Al, Sr and Ti showed wide range of concentrations. The leaves from one of the locations in Motherbunia island were characterized by exceptional high concentrations of heavy metals such as Al, As, Cu, Fe, Li, Ni, Pb that may be due to local contamination. Leaves sampled in the most seaward locations of the same island had highest concentrations of Ba, Ca, Cu, Mn and Na. High Mn concentration was found in the leaves of S. apetala of Motherbunia island. Correlations among soil and plant samples were generally very weak and organic matter content of soil did not appear to play a significant role in the nutrient supply of S. apetala.

Heavy Metals In Soils

The recycling of sewage sludge to agricultural land results in the slow accumulation of potentially toxic heavy metals in soils. A greenhouse experiment was conducted to determine the bioavailability of Cu, Ni, Pb and Zn applied to soils in urban anaerobically stabilized sewage sludge. The soils were Lithic Haplumbrept (Lh), Calcixerollic Xerochrept (Cx1 and Cx2) and Paralithic Xerorthent (Px). Sunflower plants (Helianthus annuus L) were grown in the soils following amendment with the sludge. The addition of sewage sludge markedly increased the average dry weight of the plants in the soils that had lower yields without sludge addition (Lh, Cx2, and Px). The acid pH of the Lh soil favoured the bioavailability of Zn from sewage sludge. The bioavailability of Cu was greater in the alkaline soils than in the acidic soil (Lh), which can be attributed to the high organic matter content of the Lh soil which complexes Cu and impairs its uptake by the plants. The concentration of metals in the plants increased with the sewage sludge dose. The effect of the soil type on the metal concentration in plants was greater that the effect of the dose.

The paper presents the results of studies of the Kalamitsky Bay bottom sediments pollution level with microelements and heavy metals (Pb, Zn, Cu, Ni, Co, Cr, V, As, Sr, Ti, Fe, Mn) in comparison with the content of these microelements and heavy metals in the Balaklava Bay sediments. The paper analyzes data obtained during expeditions on the R/V Professor Vodyanitsky in the Kalamitsky Gulf in August 2011 (seaward part) and on the R/V Rioni in September 2012 (coastal area) as well as in the Balaklava Bay in October 2018. Content of microelements and heavy metals in bottom sediments of the studied water areas was determined by the X-ray fluorescence method using Spectroscan MAX-G device. For the water area of the Kalamitsky Gulf, the features of the studied trace element spatial distribution are considered, groups of trace elements with different spatial distribution patterns are identified. The correlation analysis determined influence of physicochemical characteristics of the sediments on distribution and accumulation of trace elements. In the water area of the Kalamitsky Gulf, a statistically significant correlation was observed of nickel, iron and zinc content with the clay fraction; dependance of increased concentrations of zinc, nickel and chrome on the content of organic carbon and predominance of lead in highcarbonate sediments. For the Balaklava Bay, the maximum positive values of correlations with the pelitic-silty fraction were noted for iron, manganese, vanadium and chrome; organic carbon correlates with chrome, iron, nickel and copper, whereas carbonates correlate with strontium. Similar patterns were observed earlier in the Sevastopol region bays, Feodosiya Gulf and Kerch Strait.

ABSTRACT Soils of tropical regions are more weathered and in need of conservation managements to maintain and improve the quality of its components. The objective of this study was to evaluate the availability of K, the organic matter content and the stock of total carbon of an Argisol after vinasse application and manual and mechanized harvesting of burnt and raw sugarcane, in western São Paulo.The data collection was done in the 2012/2013 harvest, in a bioenergy company in Presidente Prudente/SP. The research was arranged out following a split-plot scheme in a 5x5 factorial design, characterized by four management systems: without vinasse application and harvest without burning; with vinasse application and harvest without burning; with vinasse application and harvest after burning; without vinasse application and harvest after burning; plus native forest, and five soil sampling depths (0-10 10-20, 20-30, 30-40, 40-50 cm), with four replications. In each treatment, the K content in the soil and accumulated in the remaining dry biomass in the area, the levels of organic matter, organic carbon and soil carbon stock were determined. The mean values were compared by Tukey test. The vinasse application associated with the harvest without burning increased the K content in soil layers up to 40 cm deep. The managements without vinasse application and manual harvest after burning, and without vinasse application with mechanical harvesting without burning did not increase the levels of organic matter, organic carbon and stock of total soil organic carbon, while the vinasse application and harvest after burning and without burning increased the levels of these attributes in the depth of 0-10 cm.

Sewage sludge and its management constitute one of the most important environmental problems. The introduced the Sewage Sludge Directive 86/278/EEC advocate utilization of sewage sludge in agriculture. However, this method is limited mainly by the availability of heavy metals and pathogens. An ecotoxicological assessment of sewage sludge doses applied to soil, recommended in the Polish Regulation of the Minister of Environment of 6th February 2015 on municipial sewage sludge, was carried out. The sewage sludge was added to soil in the amounts of 3, 6, 9, and 15 Mg/ha. The produced mixtures were subjected to physicochemical and ecotoxicological tests, involving the biomass and mortality tests of Eisenia fetida earthworms. The sewage sludge had a statistically significant impact on the increase in: electrical conductivity, total exchangeable cations, organic matter content, organic carbon, nitrogen and heavy metals of the considered soil. The impact on the biomass of earthworms was different; after 7 days in the mixtures with 3 Mg/ha and 6 Mg/ha sewage sludge addition, the biomass increased approximately by 1.3-fold, in comparison to non-modified soil. At 9 Mg/ha, it reduced by 1.3-fold, whereas at 15 Mg/ha – by 16-fold, in relation to the initial value. The studies indicated that the ecotoxicological assessment of wastes may be employed as environmental safety control measure of the sewage sludge application in agriculture.

Environmental context We determined seasonal changes in the organic matter content of the northern Adriatic with newly applied electrochemical techniques able to measure catalytically active organics. The inflow of the Po River and its nutrient load are responsible for the observed changes in the type and concentrations of organic matter in the area. Abstract Catalytically active polysaccharides (Cat PSs) and nitrogen-containing polymeric organic material (N-POM) were determined in seawater from the northern Adriatic station ST101. Catalytically active organics were measured by applying electrochemical methods of adsorptive transfer chronopotentiometric stripping with medium exchange and chronopotentiometric stripping in unmodified seawater. Their concentrations were expressed in milligrams per cubic decimetre–3--> of equivalents of the model calibrating substances, polysaccharide xanthan and protein human serum albumin. The optimal electroanalytical conditions for determination of Cat PSs in seawater were evaluated and defined. Seasonal changes of Cat PSs and N-POM were observed during the period 2011–2013. The highest values were determined in the spring–summer period and the lowest in winter. Cat PSs and N-POM were present in both the dissolved and particulate organic carbon fractions. Cat PSs and N-POM showed a statistically significant positive correlation with the concentrations of surface-active substances. A weak but statistically significant correlation was found between Cat PSs and dissolved organic carbon concentrations. Copper complexing capacities in the period 2011–2013 were in the range of 41–130nmoldm–3.
