“…A study conducted by Iwegbue on the determination of PTE contents of soils collected from various land uses in Benin metropolis and Benin city (capital of a southern state in Nigeria) revealed lower PTE concentrations compared to Lagos urban soils, except for Pb. 55 The overall mean levels of PTE concentrations in this study were comparable to those found in large European cities where main pollution sources include traffic and current or former heavy manufacturing industries. For instance, the levels of Cr, Cu, Mn, Ni and Pb in Lagos soils were higher than those found in cities such as Aberdeen, Scotland; Naples, Italy; Poznan, Poland; Tallinn, Estonia; Seville, Spain; Madrid, Spain and Rostock, Germany ( Table 2 ) .…”

Background.Among soil contaminants, potentially toxic elements (PTE) are of major significance because they are ubiquitous, toxic and persistent. Chronic exposure of humans to these elements has been linked with developmental delay, cancer, atherosclerosis and kidney damage, stomach ailments, respiratory problems, heart disease and cancer.Objectives.The present study aims to investigate current PTE concentrations in urban soils of Lagos, an example of a rapidly urbanizing megacity in a developing country. The variation in PTE (chromium (Cr), copper (Cu), iron (Fe), magnesium (Mn), nickel (Ni), lead (Pb) and zinc (Zn)) levels across different land use types was examined. Information from this study will be useful in the ranking of contaminated sites, environmental quality management, guidance for remediation, redevelopment of contaminated sites and will provide crucial information for general urban planning decisions.Methods.Five areas spread across four local government areas were selected, representing different socio-economic areas of Lagos (Victoria Island, Lagos mainland, Ikeja, Ifako-Ijaiye and Makoko). Sampling locations within the study areas were comprised of school playgrounds, roadsides, ornamental gardens, open spaces, train stations, industrial estates and dump sites. A total of 126 samples were collected.Results.The overall mean levels of PTE concentrations in this study were comparable to those found in large European cities where main pollution sources include traffic and current or former heavy manufacturing industries.Conclusions.Regulation and legislation on environmental issues, including effective solid waste management strategies and enforcement of emission standards should be emphasized in order to reduce the impact of PTE pollution on the inhabitants of urban areas in developing countries.Competing Interests.The authors declare no competing financial interests

“…The pH of the two soil types was 7.16 for the oxisols (fadama soil) and 6.31 for the utisols (swamp forest soil). These pH values were in the acid to near-neutral range, which is a typical characteristic of soils of the Niger Delta (Iwegbue et al 2012;Iwegbue 2014). The percentages of total nitrogen (TN) in the soils were generally low, while the TOC contents of the soils were close to the range for Niger Delta soils (Tanee and Albert 2011).…”

Purpose This study sought to investigate the effects of organic amendments on the degradation of hydrocarbons and vegetative properties of Zea mays grown in crude oil-contaminated wetland soils of the Niger Delta, Nigeria. Methods Two soil types were investigated, namely, fadama soil (oxisol) and swamp forest soil (utisol). For each soil type, 48 treatment cells and 1 control containing 1 kg of soil each were spiked with crude oil at concentrations ranging from 50 to 200 g kg −1 , representing 5-20% (m/m) contamination levels, respectively. Then, 5 days after the contamination, the soils were amended with cow dung (CD), poultry waste (PW), and palm oil waste (POW). The ratios of soil to organic amendments used were 1:1 and 2:1. The soils were tilled and irrigated regularly, and monitored for a total period of 112 days. The same conditions were used to investigate the vegetative properties of Z. mays in these oil-contaminated soils with organic amendments.Results The total organic carbon (TOC) and pH increased significantly within the first 2 weeks after crude oil contamination; thereafter, the pH of the soil decreased significantly over incubation time, while there was steady increase in TOC with incubation time. The percentage nitrogen and total petroleum hydrocarbons (TPH) decreased significantly. The utisol soil showed better plant performance, despite the lower hydrocarbon degradation rate. Conclusion The organic amendments showed a TPH degradation trend that followed the order: PW > CD > POW. They also improved the seed emergence of Zea mays.

“…In this regard, an increasing number of geochemical data on the urban areas has been reported from Europe, Asia and America (Iwegbue 2014;Kinoshita et al 2014;Li et al 2014;Guagliardi et al 2012Guagliardi et al , 2013aYuan et al 2013;Johnson and Ander 2008;Wilson et al 2008;Cicchella et al 2005Cicchella et al , 2008bFrattini et al 2006;Wong et al 2006;Smith and Huyck 1999). According to the revision made by United Nations Word Urbanization Prospects reports (United Nations 2011), 4797 thousand of people lived in urban areas of Iran in 1950.…”
