Abstract: The concentrations of nitrate, nitrite, phosphate and sulphate in some tuber crops yam (Dioscorea rotundata), cassava (Manihot esculenta), sweet potatoes (Ipomea batatas), Irish potatoes (Salomum tuberosum), water yam (Dioscoria alata) and cocoa yam (Colocasia esculenta) grown in Benue state, Nigeria were determined using spectrophotometric method according to LaMotte standard procedure. Benue state is know for it agricultural activities and it is the main supplier of food to other state in Nigeria, that is why it is called the food basket of Nigeria. The concentrations of these ions generally range from low to high values The nitrate, nitrite, phosphate and sulphate levels of these crops were however well below the tolerance levels of these anions as recommended by WHO. Accordingly, consumption of these crops as food by both human and animals may not pose any immediate health threat with respect to these anions.
