Investigating the potential of using environmental magnetism techniques as pollution proxy in urban road deposited sediment

Abstract: The use of mineral magnetic techniques as pollution proxy for road deposited sediment was explored using various statistical approaches. Standard techniques were adopted for measurement of mineral magnetic and geochemical parameters. The analyses of magnetic parameters revealed that the samples were dominated by ferrimagnetic minerals and multidomain grains. This implied that the magnetic fractions in the samples might be of anthropogenic origin. Results also indicate that the samples were dominated by low coercive, magnetically soft minerals. Thermomagnetic curves confirmed magnetite as the remanence bearing magnetic mineral having a Curie point temperature of ~580 °C. The strong association observed between magnetic susceptibility, susceptibility of anhysteric remanent magnetization and saturation isothermal remanent magnetization and aluminum, titanium, manganese, iron, chromium and lead demonstrated that these metals occurred as ferrimagnetic particles of technogenic origin resulting from vehicular sources. Assessment of pollution status of the road deposited sediment identified silicon and lead as the priority pollutants of concern. Generally, pollution load index was <1 (mean, 0.66 ± 0.14), indicating that the samples were not polluted in the overall, but the metals were in the buildup stage requiring constant monitoring. The sources of pollutants from principal component and cluster analyses identified the sources of pollution to be mainly from vehicular emissions such as brake linings, exhaust materials, tire wear, corroded metal parts, abrasion of lubricating oil and road construction materials. This study found that mineral magnetic techniques offer great potential as pollution proxy for soil pollution studies.

An Empirical Analysis of Labour Force Participation of Married Women in Adamawa State, Nigeria

Abstract: An all inclusive human capital development has long been identified as the secret behind the huge success recorded by developed and some emerging economies of the world. It is on this ground this study, Labour force participation of married women in Adamawa State, examines the factors influencing the decision of married women within the working age bracket (18 - 60 years) to participate in labour force activities. Employing the linear probability and probit models on 120 observations, it is found that women's education has a positive effect on labour force participation of married women and on the other hand, husband's employment and household size have shown a negative effect. Women's education, in an overall perspective, is found to be the major determinant of the labour force participation of married women. The present study will be of great value to individuals, non-governmental organisations, government and its agencies that are interested in gender related issues. Therefore, it is important for government to direct its policies towards proper female education as it is the key for enhancing female human capital development and productive employment.
