“…, respectively) were not significantly different. The high values of Mn and Cr in the reference area might be due to extensive use of coal by thermal power plant in this region (Jamil et al, 2009;Pandey, 2012;Tian et al, 2012;Duan and Tan, 2013). In order to gain a better understanding of the correlation structure between the heavy metals in PM 2.5 , Spearman correlation coefficient matrix was calculated ( Table 3).…”

In this study, we characterized the concentration of heavy metals in PM 2.5 in the community with e-waste dismantling, Guiyu, China and assessed potential public health risk associated with heavy metal composition of PM 2.5 for local residents. Daily samples of PM 2.5 were collected with Harvard Impactors on the roof of 3-story buildings from March 2012-April 2013 in Guiyu (n = 133) and seasonal samples were collected in a reference site, Haojiang (n = 33). The concentrations of PM 2.5 mass and heavy metals were analyzed gravimetrically and by graphite furnace atomic absorption spectrometry, respectively. The geometric mean concentrations of PM 2.5 , Pb and Cd in Guiyu were higher than in the reference area (PM 2.5 : 49.9 µg m -3 vs. 37.6 , p < 0.01; Pb: 160 ng m -3 vs. 69 ng m vs. 16 ng m -3 , p > 0.05). The metal concentrations in PM 2.5 from Guiyu were also higher when compared to other Asian cities. We observed higher heavy metal concentrations during winter and spring than summer and fall. Human health risk assessment showed that the total potential cancer risk for both adults and children are higher than the safe acceptable range recommended by the US EPA. Furthermore, the carcinogenic and non-carcinogenic elements in PM 2.5 pose higher public health risk to children than adults. The results indicate that air pollution emitted from informal e-waste recycling activities might be affecting the health of local residents, especially children.

“…Lin et al (2009) estimated the annual NO x emission over China to be 6.8 TgN using ozone monitoring instrument (OMI) and GOME-2 data. Impact on the ecosystem Other than gaseous pollution, Jamil et al (2009) found that fly ash and heavy metal pollution in the vicinity of thermal power plants creates problems in the form of land use, health hazards, and hazards to entire ecosystems. Recently, Singh and Agrawal (2010) discussed heavy atmospheric depositions nearby thermal power plants and coal mines.…”

“…Higher heavy metal accumulation on the surface of leaf and leaf tissue was found in the study emphasizing impact of combustion of coal in the nearby industries and power utility companies. Several studies have documented higher atmospheric deposition of heavy metals affecting air and water quality and effect of gaseous pollutants on the local plants and agriculture in the vicinity of thermal power plants near Varanasi and other parts of the world (Sharma et al 2008;Singh and Agrawal 2010;Fagbeja et al 2008;Jamil et al 2009). …”

The oxides of nitrogen--NO(x) (NO and NO(2))--are an important constituent of the troposphere. The availability of relatively higher spatial (0.25° grid) and temporal (daily) resolution data from ozone monitoring instrument (OMI) onboard Aura helps us to better differentiate between the point sources such as thermal power plants from large cities and rural areas compared to previous sensors. The annual and seasonal (summer and winter) distributions shows very high mean tropospheric NO(2) in specific pockets over India especially over the Indo-Gangetic plains (up to 14.2 × 10(15) molecules/cm(2)). These pockets correspond with the known locations of major thermal power plants. The tropospheric NO(2) over India show a large seasonal variability that is also observed in the ground NO(2) data. The multiple regression analysis show that the influence of a unit of power plant (in gigawatts) over tropospheric NO(2) (×10(15) molecules/cm(2)) is around ten times compared to a unit of population (in millions) over India. The OMI data show that the NO(2) increases by 0.794 ± 0.12 (×10(15) molecules/cm(2); annual) per GW compared to a previous estimate of 0.014 (×10(15) molecules/cm(2)) over India. The increase of tropospheric NO(2) per gigawatt is found to be 1.088 ± 0.18, 0.898 ± 0.14, and 0.395 ± 0.13 (×10(15) molecules/cm(2)) during winter, summer, and monsoon seasons, respectively. The strong seasonal variation is attributed to the enhancement or suppression of NO(2) due to various controlling factors which is discussed here. The recent increasing trend (2005-2007) over rural thermal power plants pockets like Agori and Korba is due to recent large capacity additions in these regions.

“…The plant leaf acts as an active or passive collector with a positive correlation between the airborne fly ash particles and micro-roughness of the leaf surface (Jamil et al 2009). The mobility of solutes varies considerably among plant species, and diffusion within cuticles is extremely temperaturedependent (Buchholz 2006).…”

Concentrations of chromium, copper, and lead were determined in soil and plant specimens collected from the area of coal power plant (CPP), A. Dimitrios, the largest CPP in Greece located on the eastern part of Ptolemais basin, Macedonia. Two cultivated plants (Brassica oleracea var. capitata L. and Zea mays L.) and two non-cultivated plants (Rumex acetosa L. and Verbascum phlomoides L.) were chosen. The mean heavy metal content in the soil is described in the descending order of Cr>Pb>Cu, while for the plant material, the order was Cr>Cu>Pb. Stations in the vicinity of the CPP showed a distinctly high load of Cr in the soil, whereas for the other metals, no such correlation has been noted. Unexpectedly, high levels of chromium and copper have been found in plant samples of the control station (Grevena) where there is no significant point source of air pollution by particulate matter. In general, roots revealed a higher metal concentration than that of the other plant organs. This is more obvious in B. oleracea var. capitata for all metals studied. Thus, B. oleracea var. capitata possesses the potential for phytoremediation of soils contaminated by metals since this plant is removable together with its roots from the contaminated soil. The most contaminated leaves showed a variation in surface roughness. In V. phlomoides the non-glandular, branched candelabrum-like trichomes on the leaf epidermis effectively trapped and retained a considerable number of particles. In contrast, the waxy cuticle of R. acetosa, which forms a smooth sheet over the epidermal cells, enabled the fast removal of particles by rain or wind. In the case of Z. mays, seeds accumulated the lowest amount of all metals.
