Nitrate, Sulphate, Phosphate and Chloride Status of Staple Food Crops, Soils and Water as Indicator of Environmental Base Anion Pollution Load in Ebonyi State, Nigeria
C.O. Edeogu

Abstract:
The levels of anions (NO3< G< , SO42< G< , PO43< G< and Cl< G< ) in staple food crops (yam, cassava, rice, maize, cowpea and African yambean); soils and water sources in Ebonyi State, Southeastern Nigeria has been quantitatively determined spectrophotometrically. The results indicate that there were significant variations in the concentrations of anions in the staple food crops across the localities with regards to SO42< G< (p< 0.001). No significant location effect in the nitrate contents of the staple food crops was observed while chloride was not detected. The anions level in the soils and surface water depicts significant correlations (p< 0.000) and that between soils and underground water is (p< 0.002). However, it was observed that the phosphate concentrations of the staple foods, soils and underground water sources exceeded the internationally acceptable limit while the sulphate, nitrate and chloride levels are within the international acceptable limit. The observed high levels of phosphate in the study areas calls for concern as it may render the staple food crops and water sources unsuitable for human, livestock and for industrial uses. Also, if not checked, soils may be unsuitable for agricultural purposes.
