Abstract: An impact study of food processing factory in Nigeria on air quality of its environment was studied using a factorial experiment. The effects of three primary air pollutants (by-products of the food processing): nitrogen (IV) oxide (NO₂), carbon (IV) oxide (CO₂) and sulphur (IV) oxide (SO₂) on formation of acid rain also studied. These factors and their interactions in the predictive model showed significant impact on hydrogen ion concentration [H⁺], which is the key intrinsic parameter of acid rain. However, SO₂ had higher detrimental influence than the other pollutants. Statistical analysis of the experimental data showed that the predictive model is adequate for obtaining optimum conditions. Validation of the model gave a correlation coefficient of 0.9999 between the measured and predicted values.
