''The Soil Pollution Power Point Presentation & file are
made with the help of ''Shri Jai Narain P. G. College''
Teachers, Professor and Head of Department of Botany.
Botany teachers Dr. Alok Mishra, Dr. A. B. Mishra, Dr.
R. K. Pandey, Dr. Vivek Singh, and Dr. S. K. Shukla
provide me notes and books. Google provide me Soil
Pollution currently information, photographs and maps
etc. Classmates provide some important notes for Soil
Pollution. Rohit Sir (Botany Department) instructed me
to make the ppt in a proper manner. My family also
help me. So thanks for all. If any mistakes, so sorry''.Vikas Nagar,

10. 1. How much material was added to the soil, will it overload
the organisms in the soil.
2. Kind of material-organic or inorganic- is the material
biodegradable/ dangerous to animals & humans.
3. C:N ratio of the pollutant material.
4. Nature of soil: will the soil be able to handle the material
before groundwater is contaminated.
5. Growing conditions for the soil organisms: - is it too
cold, too wet etc.
6. How long the material has been on site: is there
evidence of environmental problems, is it undergoing
decomposition.
