A powdered sample of Phyllanthus amarus herb from kadapa district of Andhra Pradesh India, is used in the present study. ICP-MS analysis indicates that copper is present in higher concentration when compared with other elements.Althought the Pb is toxic, it is within permissible limits. The evalauted soil and herb phsico-chemical properties indicate that the sample is acidic in nature in comparison with soil. An EPR study on the powdered sample confirm the presence of Fe(III), Mn(II), and Cu(II. Optical absiorption spectrum indicates that the Fe(III) is present in an octahedral position whereas the Cu(II) is in a rhombically distorted octahedral environment. MIR results are due to carbonate fundamentals
