Industries are located in some areas based on political influence rather than facility availability that support industry＇s productivity. In this study a criteria model was developed for assessing the present industrial site locations based on predetermined influencing factors called criteria. In the model provision was made for the sorting out of deficient influencing factors for the purpose of upgrading them to the minimum level required called benchmark through periodical allocation of appropriate funds. In validating the model, identified industrial sites located in selected States of Nigeria were surveyed. Data were collected on factors such as power supply, marketability and raw malerial availability which were considered influential to the sustainability of industry＇s site in the respective areas. Data were analysed for the criteria identified along the line of industrial categories which included large-, medium-, and small-scales. Benchmarks, as well as levels of criteria in the respective regions were determined using statistical weighted averages and the results were used as input to the model. The output results of the model showed that none of the industrial sites located in the selected six States of the South-Western Nigeria were productivity supportive. However, a good performance was achieved in a site with a budget of S13 million （US Dollars） for the upgrading of the deficient facilities in the next three years.展开更多

Results showed that PM10 concentrations exhibited the highest values at 264 μg/m3 at the site near a harbor with the influence of harbor activities. Sulfur exhibited the highest concentrations （from 2419 to 3995 ng/m3） of all the studied elements, which may be related to the influence of coal used as fuel in this area for industrial plants. This was verified by the high mass percentages of SO42-, which accounted for 34.3%-39.7% of the total ions. NO3-/SO42- ratios varied from 0.64-0.71, which implies coal combustion was predominant compared with vehicle emission. The anion/cation ratios range was close to 0.95, indicating anion deficiency in this region. The harbor site showed the highest OC and EC concentrations, with the influence of emission from vessels. Secondary organic carbon accounted for about 22.6%-38.7% of OC, with the highest percentage occurring at the site adjacent to a coal-fired power plant and wood plant. The mass closure model performed well in this heavily industrial region, with significant correlation obtained between chemically determined and gravimetrically measured PM10 mass. The main constituents of PM10 were found to be organic materials （30.9%-69.5%）, followed by secondary inorganic aerosol （7.9%-25.0%）, crustal materials （6.7%-13.8%）, elemental carbon （3.5%-10.8%）, sea salt （2.4%-6.2%） and trace elements （2.0%-4.9%） in this heavily industrialized region. Principal component analysis indicated that the main sources for particulate matter in this industrial region were crustal materials and coal/wood combustion, oil combustion, secondary aerosols, industrial processes and vehicle emission.展开更多

ArcGIS was applied to map the rail network, land uses, and industrial sites in Point Douglas and St. Boniface in Winnipeg, Canada. We identified 123 land uses with vulnerable populations needing assistance in evacuation from hospitals, senior living facilities, schools and early childhood centres within a buffer of two km of the rails and conducted hotspot analysis. About two-fifths of the total population, 39% in Point Douglas and 40% in St. Boniface, are at risk from fire, spill or train derailment involving dangerous goods and requiring evacuations or isolation.展开更多

文摘Train rails are associated with environmental and safety risks, often concentrating industry near their yards and rails. ArcGIS was applied to map the rail network, land uses, and industrial sites in Point Douglas and St. Boniface in Winnipeg, Canada. We identified 123 land uses with vulnerable populations needing assistance in evacuation from hospitals, senior living facilities, schools and early childhood centres within a buffer of two km of the rails and conducted hotspot analysis. About two-fifths of the total population, 39% in Point Douglas and 40% in St. Boniface, are at risk from fire, spill or train derailment involving dangerous goods and requiring evacuations or isolation.
