ABSTRACT

 

All living things are affected directly or indirectly by Acid Rain (AR). Biological effects of acid deposition due to AR on plants are numerous and complex. Usually, AR induced acidity is observed in plants and aquatic environment. It is a serious environmental problem. The original quality of the medium can be restoring by the introduction of alkaline substances or acid (H2SO4) neutralizing chemicals such as limestone and CaCO3 or other salts of calcium and phosphorous. In our earlier report it is observed that, instead of increasing acidity Bacopa monnieri herb shows a decrease in acidity due to sulfuric-simulated acid rain (S-SiAR) induction. Energy Dispersive Spectrometry (EDS) and X-Ray Diffraction (XRD) results confirm the presence of material phases and elements present in the plant materials. Analysis by both the X-ray techniques confirmed the presence of Ca and P elements and their phases such as (K2Ca(SO4)2:H2O) and (FeAl2(PO4)2(OH)2:8H2O) in the B. monnieri herb. So, it is expected that the chemical reactions of AR with the above material phases caused neutralization of H2SO4.
