“…It is well known that industries like bricks, iron, fertilizers, glass, coal-fired power stations, etc., are the most important sources of particulate pollution in atmosphere (Arnesen and Krogstad 1998;Haidouti et al 1993;Stevens et al 1997). Airborne particulate matter varies widely in its physical and chemical composition, source and particle size.…”

Identification of responsible sources of pollution using physical parameter particulate matter (PM)10 in a critically polluted area is discussed in this paper. Database was generated by Ambient Air Quality Monitoring (AAQM) with respect to PM10 and PM2.5 in 18 monitoring stations at Jharia coalfield as per the siting criteria (IS: 5182, Part XIV) during 2011 to 2012. Identification of the probable sources of PM10 was carried out through particle size, shape, morphology analysis (scanning electron microscopy (SEM)), suitable compounds (X-ray diffraction (XRD)) and elements (energy-dispersive spectroscopy (EDS)). Monitoring stations nearby opencast mine were affected by the big-sized and irregular-shaped particles; on the other hand, monitoring stations nearby city were affected by the small-sized and regular-shaped particles. In a city area, additional sources like diesel generator (DG) set, construction activities, coal burning, etc., were identified. Blistering effects were also observed in the particles from mine fire-affected areas. Using the X-ray diffraction technique, presence of FeS2, CuO, FeSO4 and CuSO4 compounds was observed, which indicates the effects of mine fire on particulate emission due to presence of SO4(2-) and S2- ions.

“…Noori (1991) showed Fl concentrations in collected Medicago sativa from pot room area in the Iranian Aluminium Company (IRALCO) to be 210 ppm and 94 ppm for Cercis siliquastrum. Haidouti, Chaonopoulou, and Chronopoulos (1993) reported that the average levels of Fl in vegetation ranged from 621.2 to 257.2 ppm in severely damaged areas and from 144.3 to 64.1 ppm in lightly damaged areas. It is well recognized that the concentration of Fl is a major influence on the pattern of Fl accumulation in vegetation (Haidouti, Chaonopoulou, and Chronopoulos 1993).…”

Fl has long been recognized as a potent metabolic inhibitor, which interferes with the metabolism of proteins, lipids, and carbohydrates.…”

“…The emiting industrial sources are mostly aluminum (Al) smelters and phosphate fertilizer factories, but coal combustion, steel works, brick yards, and glass works may also significantly contribute to the total Fl pollution (Haidouti, Chaonopoulou, and Chronopoulos 1993). Fl is the most phytotoxic of the common air pollutants, and considered harmful for both humans and plants (Fornasiero 2001).…”

The effects of fluoride (Fl) emission, from an aluminum (Al) reduction plant in Iran, on the concentration of Fl in six legume species were studied. In addition, the influence of Fl on leaf flavonoids was investigated. Determination of Fl in collected plants (Alhagi camelorum Fisch., Cercis siliquastrum L., Glycyrrhiza glabra L. Medicago sativa L., Robinia peseudoacacia L., and Sophora alopecuroides L.) from the factory area was performed using a Fl ion-selective electrode. Identification of flavonoids in the samples was obtained by two-dimensional paper chromatography (2-D PC) and thin layer chromatography (TLC). Controls were obtained from plants located 10 km distance from the factory. Results showed high Fl concentration in all polluted samples. Phytochemical changes in polluted leaves were observed with appearance or disappearance of some flavonoids.

“…Because the natural occurrence of fluoride in the air is usually close to the detection limit, and plants take up little from the soil, the background concentration in plants is generally quite low (often as low as 1 and usually less than 10 μg F/g dry weight in most species) (Weinstein 1977). Since HF and SiF4 are between 1 and 3 orders of magnitude more toxic than other common pollutants (e.g., O3, SO2, PAN, Cl2, or HCl), relatively small releases of fluorides into the atmosphere can result in extensive damage to plant (Weinstein and Davison, 2003) Gaseous fluorides are absorbed through leaf stomata and move by transpiration into the principal sites of accumulation at the tip and leaf margins (Jacobson et al, 1966), where they can cause physiological, biochemical, and structural damage, and even cell death, depending on the concentration in the cell sap (Haidouti et al, 1993;Miller, 1993). In addition to direct uptake through their stomata, plants can incorporate fluoride from contaminated soils (Domingos et al, 2003).…”

We obtained the following results from investigation on vegetation damage from 5 to 6 August, 2013, about one year after an accident that hydrofluoric acid leaked from a chemical maker, Hube Globe in Gumi. Pinus densiflora and Pinus strobus showed very severe damage. Ginko biloba, Quercus acutissima, Pinus rigida, Salix glandulosa, Hibiscus syriacus, and Lagerstroemia indica showed severe damage. Quercus variabilis, Lespedeza cyrtobotrya, and Miscanthus sinensis showed moderate damage. Quercus aliena, Smilax china, Arundidinella hirta, Ailanthus altissima, Robinia pseudoacacia, and Paulowinia coreana showed slight damage. We did not find any plants without leaf damage around there. This result means that fluoride damage still persists in this area as was known that fluoride remains for a long time in air, soil and water and exerts negative effects at all levels of an ecosystem. In addition, fluoride content contained in plant leaf depended on the distance from a fertilizer producing factory and vegetation damage tended to proportionate to the concentration in the Yeocheon industrial complex. In these respects, a measure for removal or detoxification of the remaining fluoride is urgently required around the hydrofluoric acid leak spot. Fertilizing of dolomite containing Ca and Mg, which can trap fluoride, was prepared as one of the restoration plans. In addition, phosphate fertilizing was added in order to enhance soil ameliorating effects. Furthermore, we recommend the introduction of tolerant plants as the second measure to mitigate fluoride damage. As the tolerant plants to make a new forest by replacing trees died due to hydrofluoric acid gas damage, we recommended Q. aliena and S. china, A. hirta, etc. were recommended as plant species to add mantle vegetation to the forest margin to ensure stable interior environment of the forest.
