Bestowing Every Continent Soil Horizons/Layers

Studying soil as a natural body requires an understanding of soil profiles. The fundamental units of morphological research are vertical cross-sections of soil profiles. Soil horizons are first primarily used to characterize soils which have evolved into a genetic and diagnostic entity. Following their deposition in soil PAHs go through a series of transport/mixing partitioning and degrading processes that ultimately control their vertical distribution in the soil.Thus the primary goal of this study is to determine the amounts of PAH concentrations in the soils that were gathered from three distinct locations in Nigeria. Second isomer compositions and ratios will be used to carry out source apportionment. Finally utilizing PAH ratios the vertical distribution features of PAH compositions and concentrations in six chosen typical soil profiles will be investigated along with their sources.Also the horizons on each continent were examined a guide to investigating toxins dispersion in soil. It requires six parts namely part 1 explains various horizons found on each continent across the globe. Part 2- gives a quick overview of some factors affecting soils and literature. Part 3- shows the necessary materials and methods employed in this study. Part 4- comprises 4a 4b 4c and 4d where the results obtained were discussed and their risk detailing unfolded. Part 5 - demonstrates why the results and Part 6 - gives critical points to justify the study.In general toxins dispersion could infiltrate groundwater soil and air. However the main focus is to reduce the level of impurities on the soil layers. This will help in food security water protection eco-system stability and above all human safety.
