Dear Chandran

I have developed a new pollution index for sediment. It has its own merits. You may find more detailed information in the attached paper. Also the scale of this index and other indices is changed by Pekey - that seems quiet logic. Therefore you may see a paper with new scale at the following link too. Combination of these two papers can help you out in your ongoing reseach.
