Contamination Levels

To identify the concentration of heavy metals in greenbelt soils of urban road in different functional zones, 0-15cm and 15-30cm soils were collected from south suburbs of Xian City. The concentrations of Cr, Pb, and Cu were determined and contamination level were assessed using single pollution index and geoaccumulation index. The results indicated that the highest contamination level was dominated by Pb and Cu. In addition, Pb was accumulated in 0-15cm soils especially, and the concentrations of three heavy metals in 0-15cm were higher than those in 15-30cm. The geoaccumulation index indicated that the contamination levels of these heavy metals in descending order was industrial area, busy roads, commercial areas, and park areas. The highest contamination degree of heavy metals were dominated by Cu, followed by Pb , which have correlation with industrial activities and traffic transport, while no Cr polluted.

<p>Bangka Island is rich in natural resources particularly tin minerals. The increasing of tin mining has elevated various wastes such as tailings, oil, and fuel coming from the sand scraper tin boat. These wastes containing toxic heavy metals may harmful to marine organism. Measurement of Pb, Cd, Cu, Zn, and Ni were carried out in September 2010. The purpose of this research was to predict the pollution degree of Pb, Cd, Cu, Zn, and Ni in sediment using two different methods namely geoaccumulation index (I_geo) and pollution load index (PLI). The samples of sediments were collected at 20 stations using Gravity Core. The content of heavy metals in all samples was determined using Atomic Absorption Spectrophotometer with a mixture of air and acetylene flame. The results showed that there was a different of prediction on sediment pollution level between Load Pollution Index with Geoaccumulation Index. According to Load Pollution Index, sediments in this waters were not polluted by Pb, Cd, Cu, Zn, and Ni (PLI&lt;1). Based on Geoaccumulation Index, sediment were also not polluted by Pb, Cu, Zn, and Ni (Igeo&lt;0). While for Cd, sediments divided into three categories, namely not polluted (Igeo&lt;0), light polluted (0&lt;Igeo&lt;1), and medium pollued (1&lt;Igeo&lt;2).  The concentration of the heavy metals still lower than that sediment quality guideline values.</p> <p>Keywords: Bangka Island, heavy metals, geoaccumulation index, pollution load index.</p>

Various industrial activities contribute heavy metals to terrestrial ecosystems. In order to evaluate the soil quality of industrial areas and to identify the potential phytoremediator from the native plant species, we collected 45 surface soil samples and 21 plant species in a typical industrial area of northwestern China. The results showed that the average values of the Cd, Cr, As, Pb, Cu, and Zn in the soils were 36.91, 1.67, 7.20, 1.38, 1.27, and 6.66 times, respectively, compared with the corresponding background values. The average single factor pollution index for heavy metals decreased in the order of Cd > As > Zn > Cr > Cu > Pb. The study area was seriously polluted by Cd and As, slightly polluted by Zn, and had relatively little contamination by Cr, Pb, and Cu. In terms of the average Nemerow synthetic pollution index in every sampling site, 97.78% of the samples were seriously polluted and 2.22% of the samples were moderately polluted, which indicated that almost all of the samples in the industrial area were seriously polluted. The results of the biomass, heavy metal concentrations, bioconcentration factors (BCF), and translocation factors (TF) for the native plants showed that Achnatherum splendens for metal Cr presented a phytostabilization potential, Artemisia scoparia and Echinochloa crusgalli for metal Cu and Halogeton arachnoideus for metal Zn presented a phytoextraction potential, and all of the studied plants were limited as phytoremediators for Cd or Pb contaminated soil.

Plant Defence Mechanisms

Heavy metals that pose a threat to the environment include lead (Pb), zinc (Zn), copper (Cu), arsenic (As), cadmium (Cd), chromium (Cr), nickel (Ni) and mercury (Hg). Biomonitoring of environmental quality using plants is widely accepted as a reliable and inexpensive way of obtaining information on contamination also by heavy metals. It allows the assessment of the direction of changes in the natural environment and development of prognoses and methods for early warning related to predicted transformations in ecosystems. This paper presents the results of field and laboratory studies on floristic biodiversity in the areas of southern Poland related to extraction and processing of Zn and Pb ores. The paper also shows the selected plant defence mechanisms against the excess of heavy metals and the results of bioindication studies using different plant species, including the selected metallophytes related to the assessment of contamination levels and the most frequently used plant ecophysiological parameters. It is necessary to monitor contamination level, popularize knowledge and take action at the level of local authorities to mitigate adverse effects of human activity, bearing in mind possible bioaccumulation of heavy metals in the food chain and the adverse health effects associated with environmental contamination.

This study provides an overview of the studies of heavy metal pollution regarding As, Cd, Cr, Hg, Pb, Cu, Zn and Ni in the urban soils throughout 71 cities of China, based on data from online literature, during the period 2003–2019. The concentrations, spatial distributions, contamination degrees and health risks of heavy metals in the urban soils were evaluated. The results demonstrated that the mean values of eight heavy metals all exceeded the soil background values in China, and the kriging interpolation method showed that the hot-spot cities with heavy metal contamination in urban soils were mainly concentrated in the southwest, southcentral, southeast coast, northcentral and northwest regions of China. The geoaccumulation index (Igeo) indicated that Hg and Cd were at moderate contamination levels and that the levels of the other six metals did not appear contamination. The pollution index (PI) showed that Cd and Hg reached high contamination levels, and the other metals reached moderate contamination levels. The integrated pollution index (IPI) and potential ecological risk index (PRI) indicated that the integral urban soils in the study areas ranked high contamination levels and moderate ecological risk degree, respectively, and Cd and Hg should be labeled as priority metals for control in the urban soils around China. The human health risk assessments for the heavy metals indicated that ingestion was the dominant exposure pathway for having adverse effects on human health. The mean Hazard index (HI) values of eight heavy metals all showed that adverse effects on human health were unlikely, and the mean carcinogenic (CR) values of As, Cr and Ni for children and adults all suggested an acceptable carcinogenic risk to human beings. In addition, children exposed to these heavy metals faced more serious non-carcinogenic and carcinogenic health threats compared to adults. The results could provide valuable information for demanding the better control of heavy metal pollution and mitigation of the adverse effects on residents by environmental regulators in national urban regions.

The article presents the content determining results of heavy metals and arsenic in sod-podzolic soils of the school grounds in Vladimir, Vladimir region. According to the accumulation indicator, the accumulation intensity of heavy metals and arsenic in these areas has been determined, which is decreasing in the series of Pb→As→Cu→Zn→Ni. The calculation of the pollutants hazard coefficient showed that their MPC excess decreases in the series of As→Zn→Pb→Cu→Ni. The soil pollution level has been assessed for the school grounds and their ecological situation has been evaluated applying the cumulative indicator of soil pollution with heavy metals and soil pollution index. The values of the soil pollution cumulative indicator of school territories indicate dangerous and moderately dangerous contamination level of the studied soils, and the calculated values of the soil pollution index refer these soils to the category of “contaminated” soils, which poses potential risks for the schoolchildren health.

This paper deals with the problem of anthropogenic soil pollution of cities with oil production on the example of Novokuybyshevsk, Samara Region. To assess the modern ecological-geochemical state of soil cover in Novokuybyshevsk in August 2016 the field study was carried out and soil samples for laboratory analysis were selected. The study was carried out on 8 test areas, 7 of which were in different functional zones of the city, significantly differing in environmental conditions. The sample site was in a green area 10 km from the city. Soil samples were collected according to the methods generally accepted in soil science and Geochemistry. The quantitative content of oil products and heavy metals (Ni, Zn, Cu, Pb, Cd, Mn) in soil samples was determined in a specialized laboratory by certified procedures on the equipment, timely verified and calibrated. The data analysis revealed significant anthropogenic transformation of the soil cover in Novokuybyshevsk, which was enriched with petroleum and heavy metals. It also shaped the conditions that increased the migration of heavy metals in soils and their availability to biota. The soils of the city are characterized by relatively even distribution and high content of Zn and Cu. On the contrary, the Mn content is characterized by a rather low rate, which is especially evident for the soil sample area. The accumulation of Zn, Pb and petroleum products in the soils of the city is connected with the influence of the industrial zone. The motor component involves the contamination of soil by Ni, Zn, Si, Cd and petroleum products. No functional area in Novokuybyshevsk contains high levels of Pb concentrations, the content of which exceeded the MPC only in the industrial area. This fact can be associated with the ban of tetraethyl use in gasoline production in Russia in 2002. The obtained results can be used for environmental monitoring of the urban environment and predict changes of ecological-geochemical situation in Novokuybyshevsk in the future.

Dynamically developing urbanization causes a number of environmental effects, including those related to the chemical transformation of soils. Relatively less information about the urban areas of the Arctic and Subarctic zones, constructed mostly on permafrost and intensively populated areas can be found. By the example of the analysis of basic soil properties and concentrations of trace metals in the soils of the cities of Salekhard, Urengoy, Nadym, Novy Urengoy and Gaz Sale (the Yamalo-Nenets Autonomous District), as well as various functional zones within the cities, the relationship between the age of the cities, the level of anthropogenic pressure and the type of parent materials and the character of accumulation of metals in the soil profile of urban soils have been described. The direct correlation was found between the content of Pb, Cr, Ni, As and soil sorption characteristics. In young cities built on sandy sediments, there is less accumulation of heavy metals in the topsoil horizons. Relatively higher concentrations of Cu and Cd were noted in soils of industrialized cities, regardless of functional zones. The higher content of Cr, Ni, Cu, Zn, As and Pb has been registered in older zones also frequently used for residential purposes. The calculated values of the PI index for some functional zones of young cities show the medium and high content of heavy metals. The analysis of Igeo and PLI indices shows a large diversity both in relation to individual cities and their functional zones. Soil quality, in spite of the high level of anthropogenic load, was assessed as mostly satisfactory.

AbstractThis geochemical study explored the distribution of potentially toxic elements (PTEs), such as As, Cd, Co, Cr, Cu, Ni, Pb, Sb, Tl, U, and Zn, along soil profiles of a metallurgical and industrial area in Kosovo, with the aim of assessing geochemical background and contamination threshold of PTEs in soil, and defining surface and vertical level and extent of soil contamination by PTEs. The geochemical background was assessed by exploratory data analysis of PTE concentrations in soil profiles. The upper limit of geochemical background (contamination threshold) was used as reference value to calculate the single pollution index and establish the PTE contamination level. Cadmium, Pb, Sb, Zn were the primary soil contaminants and As, Cu, Tl the secondary ones. The main sources of soil contaminants were the Zvecan smelter for Pb, Sb, As, Cu, Tl, and the Trepca industrial complex for Cd and Zn. The highest levels of Pb and Sb contamination were found up to depths between 30 and 60 cm in soil profiles within 5 km north and south-east of the Zvecan smelter. Contamination by Pb and Sb decreased with depth and affected the whole thickness of soil profiles closer the smelter. Cadmium and Zn contamination declined with distance from the Trepca industrial complex and decreased with depth, extending down to depths of 40–90 cm and 30–70 cm, respectively. Anomalous natural concentrations of Co, Cr, and Ni were found in soils collected in the northern part of the study area, where the geology consists mainly of ultrabasic and basic magmatic rocks.

The present paper reports the results obtained by investigation of surface bottom sediment contamination with Cu, Zn, Ni, Pb, Cr, Cd, Hg in three largest semi-closed bays of Klaipėda Port in 2008 and 2009. The concentrations of heavy metals and organic carbon same as the percentages of 6 granular fractions were determined at 41 stations. The contamination level was established by calculating the Nemerov's pollution index. The major factors responsible for sediment contamination with heavy metals and distribution patterns of discrete pollutants and different pollution areas were determined. By comparison of the obtained results with the results of 1998, the changes of sediment contamination with heavy metals in the last ten years were evaluated. It was determined that bottom sediments not contaminated with heavy metals are dominant in the semi-closed bays of Klaipėda port. Heavy contamination with nickel, and moderate contamination with zinc and copper only occur in small areas.
