Environmental pollution, of which cassava mill effluent is a component, is a global concern that appears particularly devastating to the environment and its habitats. As such, the geospatial assessment of the effects of cassava mill effluent on the environment in Ika North East Local Government Area, Delta State, was conducted. The considered parameters include potential of hydrogen (pH), electrical conductivity (EC), nitrogen (N), chloride (Cl), copper (Cu), iron (Fe), zinc (Zn), lead (Pb), calcium (Ca), magnesium (Mg), and potassium (K). Data were analyzed with a student t-test using a statistical package for the social sciences (SPSS) version 21. The parameters of the sampled soils changed due to cassava mill effluent exceeding WHO standards for land discharge. The affected soil by cassava effluent was acidic (pH = 4.92), while the unaffected soil was neutral (pH = 7.00). The significant difference between the impacted and unaffected soils by cassava mill effluent (P = .036) indicates an alteration of soil quality that can potentially induce toxicological effects on the environment and biodiversity, including humans. The values of pH, EC, N, and Fe, among others, in cassava mill effluent include 5.57, 2210, 0.40, and 50.0411, respectively. The simple linear regression analysis of cassava mill factories showed no pattern, implying the distribution is random (P = .000***). The study offers a spatial understanding of cassava effluent, its environmental impact, and pollution hotspots, enabling targeted interventions and management strategies to prevent soil, water, and air contamination in Ika and other developing regions. By leveraging tools like Geographic Information Systems (GIS) and other geospatial technologies, environmental processes can be monitored, analyzed, and modeled, leading to more informed decisions and effective strategies for sustainable cassava processing and effluent management. The study suggests effluent should be channeled into a designated pond and treated before discharge for effective control and management.
环境污染是一个全球关注的问题，木薯淀粉厂废水是其中的一个组成部分，它对环境及其栖息地似乎具有特别大的破坏性。因此，对三角州州伊卡东北地方政府地区木薯淀粉厂废水对环境的影响进行了地理空间评估。所考虑的参数包括酸碱度（pH值）、电导率（EC）、氮（N）、氯（Cl）、铜（Cu）、铁（Fe）、锌（Zn）、铅（Pb）、钙（Ca）、镁（Mg）和钾（K）。使用社会科学统计软件包（SPSS）21版进行学生t检验分析数据。由于木薯淀粉厂废水超过了世界卫生组织的土地排放标准，采样土壤的参数发生了变化。受木薯废水影响的土壤呈酸性（pH值=4.92），而未受影响的土壤呈中性（pH值=7.00）。木薯淀粉厂废水影响的土壤和未受影响的土壤之间的显著差异（P=0.036）表明土壤质量发生了变化，这可能会对环境和生物多样性（包括人类）产生毒理学影响。木薯淀粉厂废水中pH值、EC、N和Fe等的值分别为5.57、2210、0.40和50.0411。木薯淀粉厂的简单线性回归分析没有显示出规律，这意味着分布是随机的（P=0.000***）。该研究提供了对木薯废水、其环境影响和污染热点的空间理解，有助于采取有针对性的干预措施和管理策略，以防止伊卡和其他发展中地区的土壤、水和空气污染。通过利用地理信息系统（GIS）等工具和其他地理空间技术，可以对环境过程进行监测、分析和建模，从而做出更明智的决策，并制定有效的可持续木薯加工和废水管理策略。该研究建议，为了有效控制和管理，废水应排入指定的池塘并在排放前进行处理。
