Heavy Metal Release

The use of major nutrient-containing solid residuals, such as recycled solid waste materials, has a strong potential in closing the broken nutrient cycles. In this work, biofuel ash (BA) combined with green waste compost (GWC) was used as a nutrient source to improve soil properties and enhance wheat and triticale yields. The main goal was to obtain the nutrient and heavy metal release dynamics and ascertain whether GWC together with BA can potentially be used for concurrent bioremediation to mitigate any negative solid waste effects on the environment. Both BA and GWC were applied in the first year of study. No fertilization was performed in the second year of the study. The results obtained in this work showed the highest spring wheat yield when the GWC (20 t ha−1) and BA (4.5 t ha−1) mixture was used. After the first harvest, the increase in the mobile forms of all measured nutrients was detected in the soil with complex composted materials (GWC + BA). The content of heavy metals (Cd, Zn, and Cr) in the soil increased significantly with BA and all GWC + BA mixtures. In both experiment years, the application of BA together with GWC resulted in fewer heavy metals transferred to the crops than with BA alone.

This paper pertains to the influence of decreasing supplementation to transformation of chemical forms of Ni. Zn and Cu during composting of sewage sludge. A universally used supplementing material constituting a rich source of organic carbon is straw. Addition of straw to sewage sludge is aimed at increasing C/N proportion up to at least 15 due to the risk of formation of toxic forms of nitrogen, concentration of which in sewage sludge is exceptionally high. We have presented in this paper the results of speciation research of three elements applying Tessier’s sequential extraction. It’s been proven that decreasing of straw share in the composted mixture with sewage sludge down to the level of C/N value below the admissible value, has a beneficial effect on the allocation of tested heavy metals towards the forms that are permanently bound in compost matrix. A systematic increase of organic (IV) and residual (V) fractions share and decrease of mobile forms of heavy metals content in bioavailable fractions i.e. ion-exchange (I) and carbonate (II) has been ascertained.

The Impact

The paper presents the results of a long-term study on the content and distribution of heavy metals in Haplic Chernozem of agrocenoses in southern zone of Rostov Region. The impact of various agricultural technologies traditional (using moldboard ploughing) and resource-saving (minimum and No-till) on accumulation and mobility of Pb, Zn, Cu in Haplic Chernozem in winter wheat cultivation is considered. The total content of Pb, Zn, Cu in the winter wheat areas corresponds to the background level and does not exceed permissible concentrations. Low mobility of elements (Pb 2.0-3.0%; Zn and Cu up to 1.0% as a percentage of their total forms) is a regional soil feature. In addition, the low availability of Zn and Cu in soils is due to their removal with the crops in the absence of micronutrient fertilizer replenishment. The significant role of soil organic matter in the accumulation of both total and mobile forms of heavy metals in soil has been confirmed. The intensity of the cultivation methods used has a significant effect on the total content of Zn, Cu and on the mobility of Pb, Zn, Cu in Haplic Chernozem.

The features of the accumulation of heavy metals in medicinal plant raw materials Tanacetum vulgare L. in the conditions of the Trans-Urals region of the Republic of Bashkortostan are discussed. The variation-statistical indices of the content of heavy metals in soils and in plants are calculated. Soils and plants have high coefficients of heavy metals variation, with the exception of manganese in the soil, which is characterized by moderate variability. An increased level of heavy metals mobile forms, such as Cu, Zn, Mn, Fe, Pb, Cd, has been detected in all soil samples. All selected samples had an elevated level of mobile forms. According to the degree of contamination, the studied soils were classified as permissible. In tansy plants, the concentration of trace elements-biophiles exceeded the norm in Fe 1.7–6.24, in Cd 1.3–1.7 times, and the concentrations of Cu, Zn, Mn, Pb in the aboveground and underground parts of the species remained within the normal range. It is revealed that the root system of Tanacetum vulgare L. contains higher values of the studied elements than the aerial parts. According to the intensity of absorption, the elements are arranged in the following sequence: Zn → Cd → Cu → Fe → Mn → Pb. According to the coefficient of biological accumulation in tansy, ordinary zinc and iron belong to the elements of weak accumulation, copper, manganese, lead, cadmium –to the elements of weak capture.
