Abstract:
Studies on the effect of simulated acid raid rain (pH 2.0, 3.0, 4.0, 5.0 and control pH 5.6) on the growth, yield and mineral nutrient relations of Capsicum frutescens (chilli pepper) was carried out. Simulated acid rain (SAR) prepared by adding sulphuric acid and nitric acid in the ratio 3:1 to distilled water to get the desired pH, was sprayed to the plants. The experimental result indicated that under the stress of simulated acid rain, growth parameters which include plant height, number of leaves, fresh and dry weight of the test plant and stem girth decreased with decreasing pH values.

Abstract:
Rain is inherently acidic, human anthropogenic activities including pollution from homes, companies, power plants, and car vehicles, which result in the release of molecules like Carbon dioxide, Nitric dioxide, and Sulfur dioxide, are making it more and more acidic. The screen house experiment was undertaken to assess how acid rain affects plants. In the lab, to create acid rain concentrated sulphuric acid (H2SO4) and concentrated nitric acid (HNO3) were mixed in a 2:1 ratio. The desired pH level was measured using a Duplex pH meter. The plant was simulated with acid rain (pH 2.5, 3.0, 3.5, an

Abstract:
Within- and among-tree variation in assemblages of endophytic fungi in Scots pine (Pinus sylvestris) needles were studied in a subarctic area where background pollution values are low; the effects of tree density and prolonged simulated acid rain on the occurrence of endophytic fungi were investigated. The needle endophyte most frequently isolated was Cenangium ferruginosum, accounting for 64% of all fungal individuals, followed by Cyclaneusma minus (12% of all individuals). Old needles were colonized more frequently by endophytes than young ones. In young needles the colonization by endophyte

Abstract:
The seed bank composition and seedling densities were determined for a subarctic pine–birch forest. Samples (12 × 12 cm) were taken from plots that had received sulphuric acid and (or) nitric acid irrigation of pH 3 for 5 years and from irrigated control plots. The average seedling density per plot calculated from seedbank samples was 912/m2, varying from 191 to 5240. All the main aboveground taxa were present in the emerging seedlings with Betula sp. and Empetrum nigrum ssp. hermaphroditum being dominant. Other common seed-bank species included Vaccinium uliginosum, Vaccinium vitis-idaea, and

Abstract:
An experiment involving the addition of simulated acid rain to two Canadian Shield orthic humo-ferric podzolic forest soils was carried out in the field and in the laboratory. Soils were subjected to treatments of pH 5.7, 3.5, and 2.0 water containing added nitric and sulphuric acids in a 1:2 molar ratio. Pore-water concentrations of H+, [Formula: see text], [Formula: see text], [Formula: see text], and Cl− were monitored at depths of 15–60 cm for up to 2 years. Some of the laboratory columns were dismantled after 1 year and total soil N, S, soil pH, and S adsorption characteristics were measu

AbstractThe effects of simulated sulphuric acid rain were investigated, under controlled laboratory conditions, on the surface structure and n-alkane composition of the lichen Pseudevernia furfuracea. Thalli were collected from Larix decidua bark in a wood in a Piedmont alpine valley and treated with three concentrations of H2SO4. The response to simulated acid rain was a clear change in the quantitative alkane composition, with a decreasing trend observed for C28 and C30 with increasing sulphuric acid concentration. From a morphological point of view, a progressive reduction of the surface am

Abstract:
Acid rain as an important environmental issue has negative impact on bitumen performance, thereby shortening the service life of bituminous pavements. Rapid industrial and economic developments causes negative changes in the environment, including acid rain. Acid rain consisting of sulphuric acid and nitric acid has adverse effects on bituminous pavements. Both these acids react with the bitumen and adversely effect’s the properties of the bitumen leading to degradation of pavements at early stage of life. Early degradation of such pavements can be reduced to some extent by using waste plastic
