“…Na has been used as a reference element for sea salt, the δ 34 S-Na + plot can be used to identify whether rainwater is affected by sea salt (Samara et al 1992). Figure 6 shows the relationship between the Na + concentrations and the δ 34 S values of dissolved sulfate in Beijing precipitation.…”

China is experiencing serious acid rain contamination, with Beijing among the worst-hit areas. To understand the chemical feature and the origin of inorganic ions in precipitation of Beijing, 128 precipitation samples were collected and analyzed for major water-soluble ions and δ 34 S. The pH values ranged from 3.68 to 7.81 and showed a volume weighted average value (VWA) of 5.02, with a frequency of acid rain of 26.8 %. The VWA value of electrical conductivity (EC) was 68.6 μS/cm, which was nearly 4 times higher than the background value of northern China. Ca 2+ represented the main cation; SO 4 2− and NO 3 − were the dominant anion in precipitation. Our study showed that SO 4 2− and NO 3 − originated from coal and fossil fuel combustion; Ca 2+ , Mg 2+ , and K + were from the continental sources. The δ 34 S value of SO 4 2− in precipitation ranged from +2.1 to +12.8‰ with an average value of +4.7‰. The δ 34 S value showed a winter maximum and a summer minimum tendency, which was mainly associated with temperature-dependent isotope equilibrium fractionation as well as combustion of coal with relatively positive δ 34 S values in winter. Moreover, the δ 34 S values revealed that atmospheric sulfur in Beijing are mainly correlated to coal burning and traffic emission; coal combustion constituted a significant fraction of the SO 4 2− in winter precipitation.

“…We can deduce from these findings that in calcareous soils of neutro-basic pH, long-term exposures to acid rain would be necessary to produce slight acidification and, even so, no damage to ectomycorrhizal fungi would be produced. Partial neutralization of rain acidity has been already reported in Mediterranean areas due to the presence of calcareous soils (Camufo et al, 1991;Samara et al, 1992), which suggests the buffering mechanisms of the ecosystem and their importance in relation to stress phenomena such as acid rain.…”

“…More attention has been focused on pine species: Pinus strobus (Stroo et al, 1988), P taeda (Shafer et al, 1985;Walker and McLaughin, 1991;Edwards and Kelly, 1992), P sylvestris (Dighton and Skeffington, 1987;Dighton, 1988), P banksiana (McAfee and Fortin, 1987) and P thunbergii (Maheara et al, 1993). Acid rain events have been reported from Mediterranean areas such as Greece (Samara et al, 1992), Italy (Camufo et al, 1991) and Spain (Bellot and Escarré, 1988;Carratalá, 1993;Carratalá et al, 1994). Howewer, except for some studies in California on Pinus ponderosa (Temple et al, 1993), little information exists on the influence of acid rain on Mediterranean forests.…”

IntroductionThe State of Kuwait is located on the Arabian Plate between Precambrian shield to the west and Zagros fold belt towards northeast, having an area of about 17,818 Km 2 and it lies between latitudes 28°30' and 30°05' N, and longitude 47°30' and 48°36' E. Kuwait considered one of the arid regions that are primarily described by her very long period of summer season that is dry and very hot. Summer season starts from the end of March to the end of October. Between 30°C to 45°C is the range of temperature that exceeds sometimes 54°C during daytime in August. Kuwait's winter season is short, cold and relatively wet. Winter starts from early December to mid-February [1,2].Vegetation of Kuwait shows a great geographical variation in spite of the short distance from east to west. Variation in microclimate, relief, geomorphology, soil and land use made Kuwait vegetation cover shows a great geographical diversity. Furthermore, sedimentation of windtransported sand affected by vegetation, which plays an important role. Hence, it acts as a barrier that faces wind driven sand and changes surface morphology or roughness over large areas.The study area is located along Wafra/Mina Abdullah road at 14 Km south of Kuwait (Figure 1). The area is about 1 Km 2 and it is used to receive over than 4500 m 3 daily of untreated sewage and industrial hazardous liquid waste in one of the largest unlined evaporation ponds in the state of Kuwait. The study area now is completely rehabilitated and planted by several types of plants in four main sectors comprises 45000 trees.Recently published research has indicated that vegetation may play an important role in the bioremediation of toxic organic chemicals.Establishing a vegetation cover on relatively polluted hazardous waste sites might be an efficient way and low maintenance method to waste remediation. Plants Usage for remediation may be especially appropriate for soil polluted by organic chemicals especially of a depth less than 2 m 3 . Interaction between plant roots and rhizosphere microflora significantly enhances degradation of hazardous organic compounds in contaminated soil. AbstractMetal concentrations in soils are locally quite high in Kuwait due to many reasons such as massive oil spills during the gulf war in 1991 as well as direct dump for untreated sewage and hydrocarbon. Phytoremediation may offer a possible solution to this problem because it treats the soils through the use of plants even without the demand of removing the contaminated material and disposing it elsewhere. This research project focused on the best contribution of phytoremediating the area between six types of plant tree species collected (Conocarpus, Tamarix, Phoenix, Rhamnus, Vitex agnus-castus and Salix) from Wafra 14 Km area and another six reference trees from the same plant species collected for correlation from South Khitan and Rigee areas. The samples divided into three sample categories (leaves, stem, and soil). From the chemical analysis, it was found that phytoremediation is a unique pro...
