Acidic rain has received increasing interest due to the raising emissions of SO2 and NOx which determine a decrease of rain water pH under 5. The influence of such water deposition on plants leaf includes necrosis and nutrient losses. In this study the influence of simulated acidic rain on Phaseolus vulgaris L plants has been studied. In order to simulate the acidic rain, we used three different pH values (4, 4.5 and 5) of sulphuric acid solution which could occurred in the nature. The photosynthetic parameters decrease in the first 24 hours after stress application but recovered at the initial values after but only in the case of an acidic rain with pH higher than 5. The green leaf volatiles emission scale with strength stress and terpenes emission has been shown to have some protective effect. The visible symptoms of damage (chlorosis and necrosis) have been highlighted using light microscopy.
