Kursk Region

Kursk region of Russia has unique fertile soils. Heavy metals are among the factors that pollute the soil. The article is devoted to the study of the spatial distribution of heavy metals in soils. The relevance of the study is that the value of the soil is determined by its value for obtaining environmentally friendly agricultural products. Data on the content of heavy metals in the soil can prevent intensive cultivation of crops. The task of the work is to identify heavy metals that predominate in the soils of various landscapes of the Kursk region. The assessment of soil contamination with chemical elements was carried out in the course of geo-ecological studies of black earth soils in the Kursk region of Russia. The selected soil samples were examined by semi-quantitative spectral analysis. The results obtained were subjected to statistical processing. It was found that cobalt is the main pollutant in the vast majority of sampling points. In other zones, molybdenum, lead, zinc, and chromium predominate in approximately equal amounts. Soils in the surveyed area belong to the permissible category of contamination with chemical elements. Soil remediation should be applied in local areas.

The aim of this study to assess interdependence between urban soil pH and its accumulation of heavy metals. The article meant to be a contribution to a better knowledge of peculiarities and diagnostics of urban soil and its anthropogenic transformation. The hypothesis assumes that relationship between urban soil pH and its accumulation of heavy metals may be determined by the origin and age of parent material as well as the nature and degree of the anthropogenic impact. The spatial variability of topsoil pH level was performed in 100 points in eldership of Šnipiškės of the city Vilnius. Laboratory analysis was based on ISO 10390:2005. Samples were collected from 20 cm topsoil layer in the same sampling points where have been analysed concentrations of topsoil chemical elements using optical atomic emission spectrophotometry. The contamination of urban soils exhibits somewhat different compared to agricultural soils. In contradiction to earlier studies in Lithuanian agricultural soils where strong correlation between soil pH and Cr, Cd, Pb, Ni, Cu and Zd found, the conducted analysis shows a statistically reliable, but very weak (<0.3) correlation between the soil pH and concentration of contaminants. The proof to this correlation is provided by an existing relationship between pH and the concentration of copper (r = 0.20), mercury (r = 0.15), strontium (r = –0.12) and the overall contamination index (r = 0.12). The applied statistical analysis, however, failed to reveal the nature of interdependence between the soil pH and its contamination with studied heavy metals there concentration of contaminant chemical elements depends on the pH range of the soil and, conversely, the chemical reactivity of the soil changes affect on the concentration of studied chemical elements.

Absorption of heavy metals through swampy agricultural soils may have serious consequences on human health. Present study determined the levels of Chromium (Cr), Nickel (Ni), Copper (Cu), Zinc (Zn), Arsenic (As), Cadmium (Cd) and Lead (Pb) using X- Ray Spectrometry in 10 swampy agricultural soils. The result of this study revealed that, the heavy metals with their respective concentrations (Cr (278.1), Ni (462.1), Cu (314.1), Zn (502.8), As (13.5), Cd (524.5) and Pb (295.5)) were found in the soil samples in mg/kg. It also pointed out that the concentration of the heavy metals in the all soil samples for all locations in decreasing order was Cd > Zn >Ni > Cu >Pb > Cr >As. The concentration in swampy agricultural soils from Kokona was obviously higher than the safe limit set by the regulatory bodies which may be because of the geological activities in the studied area. Hence, heavy metals accumulation in swampy agricultural soils is a big concern in Kokona where people’s daily meal largely contains rice or rice based products which are mostly cultivated in swampy agricultural soils.

The continued use of waste water for irrigation of agricultural fields in Egypt may lead to accumulation of heavy metals in soils and adverse effects on soil-living communities. We investigated responses of oribatid communities to heavy metal contamination in mango plantations irrigated by the Ismailia canal in the Suez region. Mean concentrations of heavy metals determined in irrigation water were considerably above the recommended levels. Concentrations of metals in agricultural soil were however below the permissible levels. A comparison with concentrations of a typical uncontaminated soil in this area revealed that the Ismailia water canal used for irrigation of agricultural land has elevated levels of heavy metals. The results of our ecological survey showed that the abundance and structure of the soil oribatid communities were not influenced by levels of heavy metals in the soil. We also showed that the diversity index can be a valuable tool for assessing the possible impact of pollutants on different species of oribatid mites. The oribatid species appeared to be accumulating different amounts of heavy metals when characterised by their bioconcentration factors. Most species were poor zinc accumulators. The accumulation of heavy metals in the body of oribatids was not strictly determined by their body size or by the trophic level. In conclusion, our study showed that mango plantations impacted by waste water from the Ismailia canal are accumulating heavy metals in their soils above the background concentrations, but ecological effects on soil-living communities are not apparent yet.

Heavy metals especially lead, nickel, cadmium, copper, cobalt, chromium and mercury are more toxic and chief contaminants of the environment. Agricultural soils in many parts of the world are slightly to moderately polluted with heavy metals due to increase in geologic and anthropogenic activities (use of phosphate fertilizers, sewage sludge application, dust from smelters, industrial waste). Plants growing on these contaminated soils showed toxicity symptoms that results in reduce growth and activity which declined the productivity and posing threats to agro-ecosystems. They put plants under stress and affect their physiology. In this chapter, we have summarized the effects of heavy metals on plants including both symptoms and productivity.

As a result, the study using the method of x-ray fluorescence analysis with synchrotron radiation (SRX RF), for the first time obtained reliable data on the content of 20 elements in the above-ground (leaves) and underground (rhizome) plant organs Hemerocallis hybrida (sort Regal Air) growing in an urban environment in the Novosibirsk oblast. It is shown that the maximum concentration of most elements falls on the organs of plants that live in a man-made environment. The high content of heavy metals – lead, zinc, iron, manganese, copper – in the leaves was noted. The increased concentration of chemical elements in the organs of plants Hemerocallis hybrida, which suggests that they are bioindicators of the ecological state of industrial transport zones.

<p>The purpose of this research is to identify and characterize the poorly investigated problem of heavy metal contamination originating from World War I and II mass graves. Chemical elements pass systematically into the soil from metal weapons, buttons, badges, and other objects. As a result, the soil and groundwater become highly saturated with heavy metals relative to metals from communal waste. A review of previous analyses of the areas surrounding localized graves in southeast Poland revealed chemicals leached from burials to have a significant impact on the environment and groundwater. This review highlights the danger posed by mass graves that are frequently located near human settlements and rivers. However, the exact locations of the majority of mass graves are unknown and the heavy metal hazard warrants their identification and reburial in an appropriate place.</p>

The accumulation of heavy metals, primarily from the soil, takes place in the water and fodder plants. Sources are pesticides, polluted air and precipitation. Hazardous chemical elements in certain quantities enter plants from soil. It should be added that ballast substances from mineral fertilizers containing heavy metals are also found in the soil. It has been established that on the flat-foothill massif of the North Caucasus, the constant component of solid precipitation are such elements as chromium, nickel, lead, manganese and silver. Cadmium was not detected in most precipitation samples (less than 1.0 µg / l), but its concentrations exceeded the maximum permissible concentrations by 4–8 times, although its sources were not identified. Therefore, an agrochemical survey of agricultural land has been carried out and it has been established that the content of mobile forms of copper and zinc in the soils of the foothill areas does not exceed the maximum permissible concentrations. Meadow grass stands do not accumulate zinc, copper, lead and cadmium in quantities exceeding the maximum allowable levels. In general, in the foothill areas of the Krasnodar Territory, hay contains 11.0–25.0 mg/kg of zinc, 1.8–9.0 mg/kg of copper, 0.2–2.0 mg/kg of lead, and 0.06– 0.24 mg/kg cadmium. Studies have shown that the agricultural soils of the foothill areas do not contain exceeding MPC values of mobile forms of zinc and copper. But there are local foci containing lead in small quantities. In hay from arable land and natural forage lands, the amount of heavy metals does not exceed MDU.

Abstract The evaluation of the soil contaminated by heavy metals can help to judge whether the soil meets the standard and whether the pollution will threaten human health and the ecological environment. In this study, the farmland soil from eight districts in Beijing was used as the research object, and the concentration of heavy metal elements, Pb, As and Cd in the soils and agricultural products were analyzed. The analysis results showed that: (1) The evaluation based on the improved Hakanson method suggested that the crops exhibit a significantly higher ability to absorb Cd than to absorb Pb and As. Pb, As and Cd are all at normal level of ecological risk; among them, Cd is mainly in a moderate ecological risk, without strong ecological risk. (2) Based on the Improved analytic hierarchy process(AHP) of evaluation, 0.2317 is the average value of the integrated index of heavy metal pollution of soil in the study area, which is a mild level of pollution. (3) Through the calculation of various parameters in the Influence index of comprehensive quality(IICQ) of soil and agricultural products, it was found that 0＜IICQS＜1, suggesting that the environmental quality of soil is at a clean level. In summary, the pollution of heavy metals Pb, As and Cd in the farmland soils and crops in the eight districts of Beijing, including Fangshan, Daxing, Shunyi, and Shijingshan is at a low level, and no significant impact has been brought to the surrounding environment.

Agriculture is an important and significant sector in all the countries. Soil serves as a natural medium for the growth of the plants. Agricultural soil should be periodically tested for the improvement of crops. Soil physicochemical properties indicates the soil nutrient content and characteristics. The physicochemical parameters and heavy metal contamination in different agricultural soils of Coimbatore were analyzed. Soil samples were collected at the depth of 15 cm from five agricultural field. Soil samples were analyzed for physicochemical parameters and heavy metal contamination in the laboratory using standard protocols. Different agricultural soil samples were analyzed for parameters like pH, electrical conductivity (EC), TDS and salinity. Macronutrients nitrogen, phosphorus and potassium were estimated. Micronutrients like sodium and potassium also estimated for all the samples. Heavy metals like nickel, cadmium, lead, zinc, copper and manganese were estimated to check contamination status. The results stated that, all the soil samples were acidic in nature. Paddy cultivated soil was slightly alkaline in nature. All the soil samples were non-saline. Micro and macro nutrients were present in optimum level in all the soil samples. Heavy metals were present within their threshold limit and permissible limit. The study concluded that soil physicochemical parameters and heavy metal concentrations varied in five agricultural soils. Soils are good in their physicochemical parameters. This study indicates the quality of agricultural soil and it is useful to farmers regarding the nutritional and contamination status.

Environmental pollution due to heavy metals is a matter of great concern to many scientists and managers worldwide. The threats to human health from heavy metals are primarily associated with the exposure in agriculture production activities. However, a considerable number of technological methods have been used to remove the heavy metals from polluted soils. One of the simplest measures to effectively remove heavy metal contamination is to use both plants and microorganisms, which have been considered "natural materials" or "Bio-Materials" to treat pollutants. This study was conducted on assessing the ability of Trichoderma to absorb heavy metals into the plant. Phytoremediation experiments with Trichoderma were used to remove heavy metals in the soil. Our findings showed that Dracaena Fragrans plants are capable of absorbing heavy metals Cu, Pb, and Zn in soil contaminated with experimental heavy metals.
