Assessment of Industrial Pollution Load in Lagos, Nigeria by Industrial Pollution Projection System (IPPS) versus Effluent Analysis
Environmental Management in Practice, 2011Co-Authors: A. A. Oketola, Oladele OsibanjoAbstract:Lagos is the economic capital of Nigeria with over 70% of industries in the country located there. It is also the fastest growing city in Nigeria in terms of development and industrial infrastructure, forecast to be one of the three megacities in the world with population of over 20 million by the year 2025. The rapid growth and haphazard urbanization have led to an increase in waste generation and environmental Pollution. The industrial Pollution problems faced by Lagos with over 7,000 medium and large scale manufacturing facilities are directly related to the rapid industrial growth and the haphazard industrialization without environmental consideration (Oketola and Osibanjo, 2009a). Pollution abatement technologies are largely absent and the consequence is a gross Pollution of natural resources and environmental media. Since effective environmental protection cannot take place in a data vacuum, Industrial Pollution Projection System (IPPS), which is a rapid environmental management tool for Pollution Load assessment, has been employed in this study to estimate industrial Pollution Loads and to ascertain the agreement between IPPS models and conventional effluent analysis. It has been recognized that the developing countries lack the necessary information to set priorities, strategies, and action plans on environmental issues. Plant-level monitoring of air, water and toxic emissions is at best imperfect, monitoring equipment is not available and where available is obsolete; data collection and measurement methodology are questionable, and there is usually lack of trained personnel on industrial sites (Oketola and Osibanjo, 2009b; Hettige et al., 1994). In the absence of reliable Pollution monitoring data, the World Bank has created a series of datasets that have given the research community the opportunity to better understand levels of Pollution in developing countries, and therefore issue policy advice with more clarity (Aguayo et al., 2001). Hence, the World Bank developed the Industrial Pollution Projection System (IPPS), which is a rapid assessment tool for Pollution Load estimation towards the development of appropriate policy formulation for industrial Pollution control in the developing countries, where insufficient data on industrial Pollution proved to be an impediment to setting-up Pollution control strategies and prioritization of activities (Faisal, 1991; Arpad et al, 1995). IPPS is a modeling system, which has been developed to exploit the fact that industrial Pollution is heavily affected by the scale of industrial activity, by its sectoral composition, and by the type of process technology used in production. IPPS combines data from

Estimating sectoral Pollution Load in Lagos by Industrial Pollution Projection System (IPPS): Employment versus output
Toxicological & Environmental Chemistry, 2009Co-Authors: A. A. Oketola, Oladele OsibanjoAbstract:The industrial Pollution issues in Lagos with over 5000 medium and large-scale industries are directly related to the pace and pattern of the past and present industrial sector growth. In this study, sectoral Pollution Load in Lagos was estimated with respect to total value of output using IPPS Pollution intensities by medium. This was compared with sectoral Pollution Load estimated with respect to employment. There is no significant difference between the Pollution Loads estimated with respect to the two variables at p > 0.05. In most cases, the higher the total output and employment, the higher the sectoral Pollution Loads.

industrial Pollution Load assessment by industrial Pollution projection system ipps
Toxicological & Environmental Chemistry, 2009Co-Authors: A. A. Oketola, Oladele OsibanjoAbstract:Growing awareness of the harmful effects on the environment caused by industrial activities has led to increasing pressure from local communities, groups, environmental organizations, and government regulators on industries to reduce their pollutant emissions. The need for industrial Pollution assessment in the developing countries (where necessary information to set priorities, strategies, and action plans on environmental issues are lacking) has led to the development of the Industrial Pollution Projection System (IPPS) by the World Bank. IPPS is a cheap and rapid environmental management tool for Pollution Load estimation towards the development of appropriate policy formulation for industrial Pollution control.

estimating sectoral Pollution Load in lagos by industrial Pollution projection system ipps
Science of The Total Environment, 2007Co-Authors: A. A. Oketola, Oladele OsibanjoAbstract:Sensitivity to environmental issues brought about increasing pressure from local community, groups, environmental organizations and government regulators on industries to reduce their pollutant emissions. In this study, Industrial Pollution Projection System (IPPS), which was developed by the Infrastructure and Environment Team of the World Bank, was used to estimate Pollution Load in ton/yr (with respect to employment) of industrial sectors in Lagos. The IPPS was developed to exploit the fact that the scale of industrial activity, its sectorial composition, and the process technologies, employed in production, heavily affect industrial Pollution. Available data, from Manufacturer's Association of Nigeria (M.A.N.) for the years 1997-2002 was used for the estimation. From the cumulative ranking of the Pollution Load (ton/yr) estimate to all media (i.e. air, land, and water), Chemical and Pharmaceutical (CPH) sector is the highest polluting sector, followed by Basic Metal (BML), Domestic and Industrial Plastics (DIP), and Food, Beverage and Tobacco (FBT) sectors. Some of these sectors have the highest number of employees, and also appeared as the most polluting sectors in Lagos.

an improved risk explicit interval linear programming model for Pollution Load allocation for watershed management
Environmental Science and Pollution Research, 2017Co-Authors: Bisheng Xia, Xin Qian, Hong YaoAbstract:Although the risk-explicit interval linear programming (REILP) model has solved the problem of having interval solutions, it has an equity problem, which can lead to unbalanced allocation between different decision variables. Therefore, an improved REILP model is proposed. This model adds an equity objective function and three constraint conditions to overcome this equity problem. In this case, Pollution reduction is in proportion to pollutant Load, which supports balanced development between different regional economies. The model is used to solve the problem of Pollution Load allocation in a small transboundary watershed. Compared with the REILP original model result, our model achieves equity between the upstream and downstream pollutant Loads; it also overcomes the problem of greatest Pollution reduction, where sources are nearest to the control section. The model provides a better solution to the problem of Pollution Load allocation than previous versions.

simulation and evaluation of Pollution Load reduction scenarios for water environmental management a case study of inflow river of taihu lake china
International Journal of Environmental Research and Public Health, 2014Co-Authors: Ruibin Zhang, Xin Qian, Wenting Zhu, Hailong Gao, Jinhua WangAbstract:In the beginning of the 21st century, the deterioration of water quality in Taihu Lake, China, has caused widespread concern. The primary source of Pollution in Taihu Lake is river inflows. Effective Pollution Load reduction scenarios need to be implemented in these rivers in order to improve the water quality of Taihu Lake. It is important to select appropriate Pollution Load reduction scenarios for achieving particular goals. The aim of this study was to facilitate the selection of appropriate scenarios. The QUAL2K model for river water quality was used to simulate the effects of a range of Pollution Load reduction scenarios in the Wujin River, which is one of the major inflow rivers of Taihu Lake. The model was calibrated for the year 2010 and validated for the year 2011. Various Pollution Load reduction scenarios were assessed using an analytic hierarchy process, and increasing rates of evaluation indicators were predicted using the Delphi method. The results showed that control of Pollution from the source is the optimal method for Pollution prevention and control, and the method of “Treatment after Pollution” has bad environmental, social and ecological effects. The method applied in this study can assist for environmental managers to select suitable Pollution Load reduction scenarios for achieving various objectives.

effect of Pollution Load and oxygen availability on thermophilic aerobic continuous biodegradation of potato processing wastewater
Engineering in Life Sciences, 2007Co-Authors: M Lasik, J NowakAbstract:The possibility of enhancing the effectiveness of the biodegradation process of potato wastewater was evaluated. The effect of wastewater Pollution Load, dilution rate and oxygen supplementation during the thermophilic aerobic continuous utilization process on biodegradation of the main organic pollutants was investigated. Aeration performed using a stirred tank reactor (1.5 vvm, 300 rpm, 55 °C) proved to be not sufficient to provide aerobic conditions. During the continuous process, the amount of oxygen introduced into the wastewater was totally utilized by the microflora. The accumulation and decomposition of the fermentative metabolism products of the Bacillus mixed culture during oxygen limitation and supplementation were analyzed. Under microaerobic conditions (DOT < 1 %), a biosynthesis of acetic acid was observed up to a concentration of 6.5 g/dm 3 . After chemostat conditions were achieved, the level of acetic acid stabilized at 2.2 g/dm 3 . The addition of oxygen for aeration allowed a total decomposition of organic acids like acetic and lactic acid (the by-products were synthesized from partially oxidized substrates) as well as an increase in COD reduction of the wastewater (from 66 % to 79%). The periodic fortification of aeration with pure oxygen is proposed for critical situations during the continuous wastewater biodegradation when an unexpected inflow of highly polluted wastewater occurs in the system.
