Effects of Landfill Wastes on Mineral Elements of Soil and Mineral Elements Speciation

I.A. Okoro, K.K. Dimgba and E.E. Oko    

Abstract: The effects of domestic waste dumping on rural soil samples on the mineral content (s) of the soil was studied. The use of different chemical extractants to specify the state of each mineral in the soil was also investigated. The results showed that the total mineral elements in various states Viz: Exchangeable, oxidisable and soluble states in the 2 rural soil samples increase significantly when compared to non-dumping soil samples collected 1 km distance away from the two land fill sites within the same locality. Some of the mineral elements: Zinc, manganese, calcium and potassium showed more than tenfold increase in the total mineral elements due to the presence of leachates from the land fills.
