The long history of development of deposits of lead-zinc ores of the Sadonsky mining region led to the formation of extensive halos of chemical pollution of surface watercourses. Aim. The aim of this study is to monitor surface watercourses in the area of the Unalsky tailing dumps and the Kholst deposit by points of sampling of 1992-2004. Sampling was conducted in the summer of 2016. Methods. The content of heavy metals of 2 and 3 hazard classes (Pb, Cd, Ni, Zn and Cu) was studied by atomic absorption. The contribution of the Unaldon River and Unalsky tailing dump to the pollution of the Ardon River. Results. The highest content of cadmium, lead and zinc, significantly exceeding the maximum permissible concentrations (MPC) in the water bodies of cultural and domestic use is found in the Ardon River down from the Unalsky tailing dump. The flow of heavy metals into the Unaldon River with adit waters compared with the observation period of 1992-2004 decreased noticeably. In conditions of a reduction in the production capacity of mining and processing enterprises, the leaching of heavy metals from mountain dumps and excavations make an insignificant contribution to the pollution of the Ardon River in comparison with the Unalsky tailing dump. Conclusion. The state of the Ardon River down from the discharge from the tailing dump corresponds to the "environmental disaster" category. The condition of the rivers Mayramdon and Unaldon according to the content of heavy metals corresponds to a "relatively satisfactory" type.

We studied the peculiarities of bioaccumulation and distribution of heavy metals (cadmium, lead, zinc and copper) in the bone tissue, liver and kidneys of the dice snake Natrix tessellata (Laurenti, 1768) inhabited ecosystems under different anthropogenic loads in 2015-2016. Mature individuals were caught in anthropogenically transformed ecosystems of the sanitary-protective zone of the Dniprovska Thermal Power Plant (SPZ DTPP) (48.402°N, 35.111°E, n = 7), coastal ecosystems of the National Nature Park «Velykyi Luh» (47.443°N, 35.149°E, n = 8) and in the Maiorka gully ecosystems (48.260°N, 35.170°E, n = 7). The gross content of metals in the organs of N. tessellata was determined after their dry ashing in a muffle furnace. Determination of the trace elements was performed by atomic absorption spectrophotometry. Among the studied trace elements, zinc has the highest concentrations in the liver, kidneys and bones of N. tessellata. The kidneys and liver are characterized by such amount of concentrations: Zn> Cu> Pb> Cd, but bone tissue has the following ratio Zn> Pb> Cu> Cd. The highest concentration of cadmium is found in the kidneys, and the lowest one – in the bones of snakes. There are the highest contents of lead and copper in the snakes’ liver, but the lowest in the kidneys and bones. The lead bioaccumulations in organs of snakes from different ecosystems are dissimilar. Zinc content in bones is higher than in kidneys and liver, but the lowest concentration is found in the kidneys. It has been found that the highest contents of toxic metals (Cd, Pb) were in the kidneys and liver of the snakes dwelled in the SPZ DTPP ecosystems in comparison with both studied natural ecosystems. In addition, snakes caught in anthropogenically transformed ecosystems of SPZ DTPP are characterised by increased zinc content in all studied organs and enlarged copper concentration in the kidneys. Considering the obtained results on the metals bioaccumulation, the dice snake can be considered as a potential bio-indicator of environmental pollution by heavy metals.

Variations of heavy metals in sludge during microwave pyrolysis and muffle pyrolysis were analyzed by means of scanning electron microscope (SEM) and inductively coupled plasma atomic emission spectrometer (ICP-AES). Increased basicity of residues from the sludge is found. Leaching percentages of heavy metals ranging from 0.031% to 5.364% after microwave treatment are lower. Releases of cadmium, lead, zinc and copper from the residues obtained in microwave pyrolysis reduce by 92.68% compared with muffle pyrolysis. Alkaline intermediates formed in the pyrolysis residues bring about improved immobilization of heavy metals. Transformation in morphology of heavy metals and strong alkaline of the residues, lead to the immobilization of heavy metals during microwave pyrolysis.

AbstractIn the everyday human diet, cereal products are considered to be basics. Such food should have healthy properties and not contain harmful additives, especially heavy metals as exposure to low doses of such xenobiotics can adversely affect human health. Ecological farming is the answer to consumer expectations regarding food safety, and ecological products are recommended as a basis for proper nutrition, despite the higher cost of their purchase. The present study was carried out to evaluate the content of heavy metals in ecological cereal products and their non-ecological analogues.

The content of heavy metals (cadmium, lead, zinc, copper) in the soil and in the body of insects was studied using an inversion volt-amperometric method of analysis (SWV) and spectrometric analysis using ICP 730-ES. Samples for analysis were selected at the Malinki biological station (on the border of the Podolsky and Narofominsky districts of the Moscow region) and at the Pavlovskaya Sloboda agrobiological station (located in the Istrinsky district of the Moscow region). Studies have allowed us to provide an environmental assessment of the composition of the soil and the content of heavy metals in the body of insects. According to the degree of contamination of the organism of insects of the Chrysomelidae family (leaf beetle) and the Carabidae family (ground beetles), the studied metals can be arranged in a series of zinc > lead > copper > cadmium, which practically coincides with a number of pollution of the studied soils by these metals.

The article focuses on the study of change of containing heavy metals (zinc, copper, iron, cadmium, lead, arsenic) in the abiotic and biotic components of the Serepok river (Vietman) influenced by wastewater discharge from industrial areas. Heavy metal content was determined in the river water and bottom sediments in the four zones: above and within the boundaries of industrial regions Xoa Phu and Tam Thang and in two water reservoirs situated below the boundaries of those industrial areas. Tilapia Galilean ( Sarotherodon galilaeus ), Hemibagrus ( Hemibagrus ), and sazan ( Cyprinus carpio ) caught in these areas were the hydrobionts under study in which liver, gills, skeleton and muscles accumulation of heavy metals was detected. In the organs of fish caught in the river within industrial region, heavy metals concentration was 3-7 times higher. The greatest concentration of heavy metals was found in the liver and gills of fish caught in the boundaries of industrial regions, the least concentration was in the muscles. In most cases, significant correlation between heavy metal concentration in organs of fishes and in river water, bottom sediments has been revealed.

Runoff from highways contains significant loads of heavy metals and hydrocarbons. According to German regulations, it should be infiltrated over embankments to support groundwater-recharge. To investigate the decontaminating effect of greened embankments, soil-monoliths from highways with high traffic densities were taken. Soils were analyzed to characterize the contamination in relation to distance and depth for lead, zinc, copper, cadmium, PAH and MOTH. Lysimeters were charged in the field and laboratory with highway runoff to study the effluents under defined conditions. Concentrations of pollutants in roadside soils depend on the age of embankments and traffic density. Highest concentrations were found in the upper 5 cm of the soil and within a distance of up to two metres from the street. Concentrations of most pollutants decreased rapidly with depth and distance. Lead and cadmium could not be detected in lysimeter effluent. Zinc and copper were found in concentrations that did not exceed drinking water quality limits.
