Heavy Metals Pollution

Heavy metals (Hg, As, Pb, Cd, Cr, Cu) pollution in soil samples of Rosa sterilis planting areas located in Wudang District in Guiyang and Pingba County in Anshun was studied using a new evaluation theory of pollution loss rate, and following a series of methods for Rosa sterilis leaf including over standard rate, enrichment coefficient, single pollution index and comprehensive pollution index, the heavy metals pollution of the two Rosa sterilis planting areas was analyzed and evaluated. The results showed that the soil comprehensive pollution loss rate ranged from 12.73% to 28.26% in Wudang District samples, most of which belong to light pollution level. The comprehensive soil pollution loss rate of the sampling points in Pingba County varied from 9.68% to 16.10%, which belong to fairly clean level. Meanwhile, the experimental results for the Rosa sterilis leaf showed that the contents of Cr and Pb in both planting areas exceeded the permissible limit, while other elements were below the safe limit. The six heavy metal elements in Rosa sterilis leaf did not accumulate.

To investigate the characteristics and potential sources of heavy metals pollution, surface sediments collected from Bohai Bay, North China, were analyzed for the selected metals (Cd, Cr, Cu, Ni, Pb, and Zn). The Geoaccumulation Index was used to assess the level of heavy metal pollution. Pb isotopic compositions in sediments were also measured to effectively identify the potential Pb sources. The results showed that the average concentrations of Cd, Cr, Cu, Ni, Pb, and Zn were 0.15, 79.73, 28.70, 36.56, 25.63, and 72.83 mg/kg, respectively. The mean concentrations of the studied metals were slightly higher than the background values. However, the heavy metals concentrations in surface sediments in Bohai Bay were below the other important bays or estuaries in China. The assessment by Geoaccumulation Index indicated that Cr, Zn, and Cd were classified as “the unpolluted” level, while Ni, Cu, and Pb were ranked as “unpolluted to moderately polluted” level. The order of pollution level of heavy metals was:Pb>Ni>Cu>Cr>Zn>Cd. The Pb isotopic ratios in surface sediments varied from 1.159 to 1.185 for206Pb/207Pb and from 2.456 to 2.482 for208Pb/207Pb. Compared with Pb isotopic radios in other sources, Pb contaminations in the surface sediments of Bohai Bay may be controlled by the mix process of coal combustion, aerosol particles deposition, and natural sources.

Both single pollution index and integrated pollution index methods were employed in the present research to assess the heavy metals pollution of soil in the threeRosa roxburghii TrattPlanting Bases (located in Qianxi County and Qixingguan region in Bijie, Longli County in Qiannan), the baseline values of heavy metals in soils in Guizhou Province, Environmental Quality Standard for Soils (GB15618-1995) and Conditions of Green Food-tech0.nical Environmental Quality for Production Area (NY/T391-2000 and GB/T18407.1-2001) were applied as references. National Food Safety Standard-Contaminants in foods was applied to evaluateRosa roxburghii Trattfruits. The results suggest that the studied soil samples conformed to Environmental Quality Second Level Standard for Soils and Green Food-technical Conditions. The overall quality of the soil conditions was uncontaminated, but point source pollution phenomenon existed. Hg, Pb and Cu pollution were the main factors contributing to the rise in comprehensive pollution index from the threeRosa roxburghii TrattPlanting bases. It was found that levels of As and Cu did not exceed the limited standard of the soil，while Hg, Cr, Cd and Pb exceeded the standard in different degrees in studiedRosa roxburghii Trattplanting bases. The rates of excessive quota of Hg, Cr, Cd and Pb in the studiedRosa roxburghii Trattfruits was 6.67%, 13.33%, 73.33% and 100%, respectively. The mean accumulation coefficient of Cd forRosa roxburghii Trattfruits was up to 1.20. The mean accumulation coefficients for concerned heavy metals were in the order of Cd > Cu > Pb > Hg > As> Cr. The relationships between concentrations of heavy metals in soil, leaf and stem samples were weak. However, significant correlations were found between concentrations of As in soil and leaf samples (r = 0.928), and concentrations of Cr between in soil samples and Cr in leaf samples (r = 0.733).

Drinking water of safe quality is a critical issue for human survival and health. Water pollution by heavy metals is very crucial because of their toxicity. This study assesses potential of heavy metals pollution in drinking water in Garmian Region, East Iraq. Water samples were investigated for 23 heavy metals and 6 chemical contaminants collected from 16 locations. The analysis was performed by using coupled plasma optical emission spectroscopy (ICPOES, Spectro Arcos). High levels of Al, Se, Sr, and Fe have been detected at certain locations in study area. Statistical analysis techniques of the correlation matrix (CM), and cluster hierarchical analysis (CA) were conducted. The heavy metals pollution index (HPI), heavy metals evaluation index (HEI), and contamination Index (Cd) were used applied. These indices linked with the statistical analysis to interpret relationships among the tested parameters in water samples and to investigate the pollution sources over the study region. Even with the significant correlations between the HPI, Cd, and HEI, they showed dissimilar impact of examined heavy metals on the water quality. The most reliable pollution evaluation index of HEI for drinking water showed that 44% of the water samples is critically polluted. Sources of the contamination are most likely coming from natural geological sources. Anthropogenic impact was only noticed at several sites in the study area.

Abstract The ecological risks and health hazards of heavy metals pollution in Taihu Lake have received widespread concern. This study has developed a nationwide dataset on pollutant loads in species, and the dataset records 55,297 data from 310 articles, covering 778 species and 537 pollutants. In this paper, we extract and systematically integrate data on heavy metals concentrations in Taihu fish from the dataset. The Pi (single pollution index) and MPI (metal pollution index) models were used to assess the level of contamination in fish and the THQ (target hazard quotient) and ILCR (incremental lifetime cancer risk) models were used to assess the health hazards of fish consumption. The contamination levels varied in a feeding habit and living habit dependent manner. The risk of non-cancer health is the highest in omnivorous fish, then in carnivorous fish and herbivorous fish. ILCR model predicted that the values of As and Cd in omnivorous fish for children exceeded the risk threshold limits set by the EPA, and the ILCR values of As in omnivorous fish and Cd in carnivorous fish for adults also exceeded the risk threshold limits. In all, this study provided a comprehensive understanding of the risk of heavy metals in Taihu.

A study was conducted to determine the current status of the heavy metals in roadside dusts collected from Chang'an Street in Beijing, China. Ten sampling sites were selected and analyzed to determine the concentration and pollution assessment of heavy metals in roadside dusts. The results showed that the concentrations of Cr, Cu, Zn, Cd and Pb were higher than the local soil background values, indicating that the heavy metals pollution may come from anthropogenic input. The assessment by Geoaccumulation Index (Igeo) indicated that Cr and Ni were at the unpolluted level, the other elements were at the uncontaminated to moderately contaminated level. The pollution level of the heavy metals was: Ni < Cr < Pb < Cu < Zn < Cd.

Evaluation Of Data

The aim of the study is to correlate spectrophotometrical analysis data of soil and bees honey samples statistically evaluated in order to predict the heavy metals pollution level of a geographical area only based on the analysis of bee’s products (bees honey and pollen). The natural concentrations of some metals in soil vary from a region to another depending on the rocks nature and composition as well as on the contribution generated by human activities like: combustions, minerals treatment, gas additives, cigarette smoke, and other industrial activities. Important quantities of heavy metals are discharged in the atmosphere and in the continental and oceanic waters from where it is getting at tissue level. The statistical evaluation of data is able to provide information about the geographical areas heavy metals pollution.
