Abstract : Rice is a very popular commodity amongst Nigerian families, however the demand for rice is on the rise daily, hence an increase in rice milling activities across the country. This study is aimed at determining the impact of rice milling activities on soil quality. The samples were gotten from Auchi, Anambra and Kogi State. The samples were digested and analysed using a varian 220 atomic absorption spectrometer (AAS). Physicochemical properties showed the ph of the soil, ranging from 6.7 -9.84, temperature 29.1oC – 30oC and electrical conductivity of soil ranged from 1.3(μS/cm )- 88.2(μS/cm). The available nutrients in the soil revealed the highest values for nitrogen to be 52.2779 (mg/kg), and phosphorus to be 296.421 (mg/kg), while the highest value for potassium was 188.315 (mg/kg). Conclusively, The rice mill operations was seen to affect the soil quality parameters, due to the release of effluents on the soil, resulting in an increase in the heavy metal concentrations in the soil and decrease in the available nutrients. Accumulative geo-index revealed that Auchi is moderately polluted with cadmium and Anambra is highly polluted with zinc.

Keywords : Rice Mills, Soil Nutrients, Heavy Metals, Accumulative geo-index, Anthropogenic Metals.
