Bilal <p>Nitrogen dioxide (NO<sub>2</sub>) plays significant role in atmospheric chemistry mainly in secondary air pollutants formation which consequently result in environmental acidification.&nbsp; It has adverse impact on human health and considered as the second most harmful air pollutant after PM<sub>10</sub> in major cities of Pakistan including Lahore. In this study, 15 major urban sites of Lahore with respect to vehicular flow were focused during rush hours from 1:30 pm to 9:30 pm for the monitoring of NO<sub>2</sub> level. Chemiluminescence technique was applied to identify NO<sub>2</sub> concentrations by using Horiba APNA-370 monitor. For sampling, four months of winter season November 2016 to February 2017 were selected and measured monthly average mean values; associated meteorological conditions like temperature, wind speed, rainfall and relative humidity were also monitored. A spatial distribution map of different locations for NO<sub>2</sub> concentrations was developed by using geostatistical tool ArcGIS. The highest NO<sub>2</sub> values near the main roads were mainly due to intense traffic flow and vehicular emissions unlike residential and commercial locations. Moreover, the NO<sub>2</sub> level exceeded the NEQS standards at most of the sampling points during study. Therefore, it is mandatory to take desired steps in order to develop effective mechanism to control air pollution before it becomes a serious hazard for human beings living in urban areas.</p> 2022-07-25T00:00:00+00:00 ##submission.copyrightStatement## Resident Perceptions on the Health Risks Associated with Solid Waste Disposal at Kalundu Dumpsite, Kitui County – Kenya on the Surrounding Human Settlement 2022-08-04T05:50:36+00:00 Valilian Kavutha Matheka Bonface O. Manono Felista Muriu-Ng’ang’a <p><strong>Aims: </strong>Urban centers of developing countries are growing at very rapid rates. This has been accompanied by increased use of resources and enormous waste generation. The generated waste is dumped in the outskirts of the urban where they can have negative impacts on the environment and surrounding human settlements. This study therefore aims to assess the perceived health risks of Kalundu dumpsite in Kitui Town, Kitui County of Kenya.</p> <p><strong>Study Design:</strong>&nbsp; A survey design was used to collect data from people living within 500 meter radius of Kalundu dumpsite.</p> <p><strong>Place and Duration of Study: </strong>This study was carried out between January 2020 and December 2020 in Kitui Town of Kitui County, Kenya.</p> <p><strong>Methodology:</strong> A Semi - structured questionnaire was administered to 78 respondents to collect data on perceived health risks they associate with the presence of Kalundu dumpsite in their locality. The collected data was coded and then analyzed. Pearson Correlation Coefficient was used to test the link between respondent characteristics and perceived health risks.</p> <p><strong>Results:</strong> 83.3% of respondents perceived the presence of the dumpsite in their vicinity as a health hazard that they attributed to cause diseases (Malaria, chest pain; diarrhea, and cholera) and other negative environmental effects (smoke, odour, and habitat for disease vectors and pathogens). Children under the age of 5 years were the most vulnerable.</p> <p><strong>Conclusion:</strong> There is a perceived link between waste deposited onto Kalundu dumpsite and human and environmental health of the surrounding community.</p> 2022-08-01T00:00:00+00:00 ##submission.copyrightStatement## Appraising the State of Knowledge of the Valuation of Contaminated Freshwater Ecosystem of the Niger Delta 2022-08-06T11:18:12+00:00 Deeyah Christopher L. Akujuru Victor A. <p>The valuation practice utilised in valuing natural resources in the Niger Delta has shown signs of the paucity of professional knowledge, thus necessitating an appraisal of the state of knowledge possessed by valuers practicing in the Niger Delta. This paper assesses the state of knowledge among Niger Delta valuers in contaminated freshwater on the applicability of the methods of valuation for assessing damaged freshwater resources. With reference to freshwater ecosystem valuation, a survey of practicing valuation firms was conducted on 102 valuation firms using census sampling, and (11) expert valuers were interviewed purposively. Findings indicate a poor knowledge of environmental valuation techniques and a constant recourse to using a predetermined compensation rate in valuing contaminated natural resources. It thus recommends the intensive training and education of practicing valuers on methods of environmental valuation and the valuation of contaminated natural resources.</p> 2022-08-03T00:00:00+00:00 ##submission.copyrightStatement## Water Balance Analyisis of Asa Lake Area and Environs, Ilorin, Kwara State 2022-08-13T05:33:11+00:00 B. M. Gwari M. U. Jikantoro Y. A. Birnin Yauri Oluremi J. O. <p>This study&nbsp; assessed the water availability in Ilorin for increased fisheries production. The study used rainfall secondary data for the period of 20 years obtained from NIMET Office, Ilorin. Evapotranspiration data for the area was empirically generated while water balance model was computed using MATLAB R2007a version in order to ascertain the respective water availability. Regression analysis was used to ascertain&nbsp; rainfall trends. The findings showed that rainfall amounts vary from one year to another and also there was record of&nbsp; an increasing trends in the area over the period.&nbsp; It is also revealed that the period received more rainfall which could better be descriped as wet&nbsp; years&nbsp; showing that thare was abudant water resources in Ilorin.&nbsp; Therefore,&nbsp; more efforts should be geared towards harnesssing the excess rainwater for various purposes. This is to increase the capacity of water reservoirs and dams across the State for development of pipe borne water network, irrigation farming during insuficiency; and fisheries production. Further investigation is recommended on water balance and its implications for agricultural practice in the study area.</p> 2022-08-11T00:00:00+00:00 ##submission.copyrightStatement##
