Research ArticleOpen accessIn the keywordsSocio-Economic, Health and Environmental Aspects of Child Waste Picking Activity at Africa's Largest DumpsiteAmos Oluwole Taiwo, Olanrewaju Timothy Dada, Adetola Samuel Ayoola, Gbemiga Bolade FaniranThis study examined the social, economic, health, and environmental aspects of child waste picking at the Olusosun dumpsite in Lagos, Nigeria. A questionnaire was administered through the convenience sampling technique to 150 child waste pickers. Findings showed that recovering materials from the dumpsite involved physical energy and manually-operated rudimentary tools. A majority (62.0%) of the child waste pickers were males … …American Journal of Environmental Sciences, Vol. 18, Issue 3 · 2 Jul 2022 · 7,563 accessesView PDF Cite

In this study hazard risk in urban areas could be useful through considering are used to model human activities such as population, land use and strategic situation in Zayandeh Rood Basin … …American Journal of Environmental Sciences, Vol. 13, Issue 2 · 12 Apr 2017 · 7,094 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsExploring the Inadequacy of Pertinent Capacities for Urban Flood Risk Management in the Developing CountriesNkwunonwo Ugonna Chimnonyerem, Chiemelu Emmanuel Ndukwe, Nkwunonwo Ugochi AdannayaOf all the widespread natural hazards with large scale human, economic and environmental impacts, flooding surpasses. In the urban areas, the threats of this hazard are substantial and call for ever more attention, which, within the contexts of sustainable human and urban development, is increasingly an important problem in social science research. Urban flooding is a relatively new hazard phenomenon, … …Journal of Social Sciences, Vol. 12, Issue 3 · 18 Aug 2016 · 7,828 accessesView PDF Cite

Review ArticleOpen accessIn the keywordsA Review of Flood Risk Analysis in NigeriaAkinola Adesuji Komolafe, Suleiman Abdul-Azeez Adegboyega, Francis Omowonuola AkinluyiNigeria has witnessed diverse flood events in the past years and due to the high level of vulnerability and lack of coping capacity of the people, with the fast occurrence of extreme events resulting from climate change, many lives and properties are at risk of its impacts. This paper reviews the recent past and present efforts in assessing the flood … …American Journal of Environmental Sciences, Vol. 11, Issue 3 · 12 Sep 2015 · 10,800 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsResidual Chromium in Leather by Instrumental Neutron Activation AnalysisS. Okoh, I. O. Okunade, D. J. Adeyemo et al.Problem statement: Most tanning processes employ the use of chromium sulphate. For chromium tanned leather, finished products may contain high amount of residual chromium. This may pose some health hazards, since chromium is known to be toxic at elevated concentration. This justifies the need for the study. Approach: Various samples of leather were collected from a tannery, a leather crafts … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 17 Jan 2012 · 7,499 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsIntegrated Modeling for Flood Hazard Mapping Using Watershed Modeling SystemSeyedeh S. Sadrolashrafi, Thamer A. Mohamed, Ahmad R.B. Mahmud et al.In this stduy, a new framework which integrates the Geographic Information System (GIS) with the Watershed Modeling System (WMS) for flood modeling is developed. It also interconnects the terrain models and the GIS software, with commercial standard hydrological and hydraulic models, including HEC-1, HEC-RAS, etc. The Dez River Basin (about 16213 km2) in Khuzestan province, IRAN, is domain of study … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2008 · 10,792 accessesView PDF Cite

Research ArticleOpen accessIn the abstractTAGN-IDC: Implicit Discrete Constraints for Tsunami Aware Graph Neural Networks in Spatial Evacuation RoutingSularno, Wendi Boy, Putri Anggraini et al.Tsunami evacuation route requires rapid identification of safe evacuation paths under dynamically changing hazard conditions. A major challenge is incorporating hard binary road-blockage constraints caused by tsunami inundation while maintaining end-to-end differentiability for deep learning models. Existing approaches commonly rely on continuous relaxations or stochastic sampling techniques, which either compromise physical feasibility or increase computational complexity. This study proposes the … …Journal of Computer Science, Vol. 22, Issue 9 · 24 Sep 2026 · 704 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAutomobile Spray Paint Dust and Human Health: A Multi-Site Environmental Health Risk Assessment of Carcinogenic and Non-Carcinogenic Effects in South-Eastern NigeriaAdindu Ihuoma Blossom, Ubouh Emmanuel Attah, Obasi Kalu Omokorie, Raimi Morufu OlalekanInformal automobile spray-painting operations release metal-laden dust, posing occupational and residential health risks. Seasonal variations, receptor-specific exposure, and metal composition influence non-carcinogenic and carcinogenic hazards, yet data from South-Eastern Nigeria remain limited. This study quantified heavy-metal exposure in automobile spray-paint dust, assessed receptor-specific non-carcinogenic (HI) and carcinogenic (ILCR) risks, examined seasonal and metal-specific trends, and evaluated source attribution to inform … …American Journal of Environmental Sciences, Vol. 22, Issue 1 · 22 Jun 2026 · 1,555 accessesView PDF Cite
