This research is informed by the generation of waste and pollution by the multi-national oil companies, the improper management of the wastes and the horrific consequences of the indecorous management. The theoretical framework of the research is Ecocriticism, a literary theory which applies ecological phenomena to the study of literature by examining the effects of human activities on the environment. The aim of this article was to investigate the portrayal of various forms of environmental mismanagement in the Niger Delta by Ejike in his novel, Oil at my Backyard . It is a case study that the detailed analysis was based on the novel, other critical works and available literature on oil exploration in the Niger Delta. As a case study, it examined the various spheres and manifestations of waste, its economic, social and health implication on the people and the city. The significance of the investigation lies in additional corpus of information on the discourse of human rights abuse by the multi-dollar oil companies in terms of negligence of corporate social responsibility on the host communities. The author discovered the insensitive disposition of the oil companies with regard to waste management which has resulted in attacks on the oil companies and their staff, destruction of aquatic life and emergence of militancy with its attendant effects on the city and other social and economic imbalances. The author recommended, among others, the development of sustainable mechanism towards waste management in collaboration with the host communities.","PeriodicalId":35178,"journal":{"name":"WIT Transactions on Ecology and the Environment","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46830494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study, 42 water samples, including surface and groundwater, from six different sampling points of the Hazaribag tannery complex were examined for one year (December 2019– August 2020; dry and rainy seasons respectively). This research aimed to assess the surface and groundwater quality of the sampling area and the seasonal variation on different parameters. During sampling, a sequence was maintained, from the tannery source points to the downstream Buriganga River, the ultimate destination of tannery effluents. Chemical and physicochemical properties pH, DO, BOD, NO 3- , C 2+ , Mg 2+ , K + , Na + , Cl - , TDS, TSS, EC, Eh, and turbidity of wastewater were evaluated using the standard method. However, our primary attention was on heavy metal contamination. Trace metals were analyzed by atomic absorption spectrophotometer. The excessively higher concentration of heavy metals was observed in the first three sampling sites. It was also found that heavy metal concentrations decreased significantly from the source point to the downstream Buriganga River. Such variations in metal content with the location may have occurred due to increasing distance from the source point and percolation of wastewater to downward groundwater by soil. Comparatively lower concentrations of heavy metals were observed in the rainy season than dry season due to dilution with rainwater but still was above the maximum allowable concentration. Concentrations of all investigated heavy metals and some physicochemical parameters such as pH, DO, BOD, TDS, TSS, EC, Cl - , and Na + of all the surface and groundwater samples were found above the national (DoE) and international (WHO) standards . tannery effluents.","PeriodicalId":35178,"journal":{"name":"WIT Transactions on Ecology and the Environment","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48426036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, reclaimed water has proved to be a viable option for ensuring water availability for such a water-demanding and critical sector as agriculture is. Nevertheless, its use is too often seen as a last-resource alternative desired mainly by farmers facing water scarcity or a lack of water alternatives. Despite the pressing need to look for reasons that justify the profitability of its implementation over other water alternatives, and in light of there being gap research when analyzing all the benefits of using reclaimed water from a holistic economic approach, the overall objective of this study is to evaluate the economic impact generated by the use of tertiary water in agriculture to irrigate crops. To reach this ambitious objective, the economic value of a large list of positive externalities derived from the implementation of reclaimed water in agriculture is going to be calculated. Some of the aspects that are going to be evaluated are: its fertilizer value affecting crop productivity, soil quality and plant growth and its capacity of being a source of organic carbon. Furthermore, these others relevant aspects that too often go unnoticed due to the difficulty in their measurement are going to be evaluated: its contribution to protect water bodies and promote water resources quality and recovery, its capacity of enhancing and boosting marine ecosystem services and its leverage effect in promoting agriculture in new areas and in fostering different crop varieties in other areas where, because of salinity levels or water scarcity, only some crop varieties may be grown. Results will show through economic data and results the urge of implementing reclaimed water in agriculture worldwide.","PeriodicalId":35178,"journal":{"name":"WIT Transactions on Ecology and the Environment","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42939156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The fact that these elevated levels of pollution do not seem to follow any specific pattern explains why current models still struggle to provide an accurate prediction of these harmful events for human health. The present study tackles this issue by testing several supervised learning methods to discriminate between peak and no peak of concentrations of five contaminants: NO 2 , CO, SO 2 , PM 2.5 , and O 3 . The classification performance of ensemble decision tree (gradient boosting machine (GBM)) models and ensemble deep learning (EDL) models are compared. The results reveal that the EDL outperforms the GBM model. An analysis of the variable importance (SHapley additive exPlanations (SHAP)) shows that both temporal and meteorological features have an impact on the proposed models. In particular, time of day and wind speed are the most important features to explain the performance of the ensemble DL models.","PeriodicalId":35178,"journal":{"name":"WIT Transactions on Ecology and the Environment","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43161452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Utilizing marginal land for production of these feedstocks alleviates the competition of fuel versus food that comes with use of prime agricultural land. Canada has a large area of marginal land. Sorghum is an important plant for food, fodder, and forage production. It is regarded as a nature-cared plant with low input requirements and is recommended as a top crop for removing carbon from the atmosphere. As a part of a collaborative project to develop a system for producing biomass (sorghum) on marginal land in Canada, this research focuses on the species and their distribution, mobility and availability (to plants) of nitrogen (N) and phosphorous (P) in marginal land soils from selected locations in Canada. US EPA method 1312 was followed to simulate the leaching process of nutrients from soils in the natural environment. Colorimetry and ICP-OES were used for the determination of the nutrient species. Preliminary results show that the predominant leachable and plant-usable form of nitrogen is nitrate (NO 3– ) while the majority of phosphorus in the soil is not water leachable; depth variation of leachable nitrogen and phosphorus species in the soils is indicated; the concentrations of nitrate in the soils increased shortly after N-fertilizer application but the level decreased to that observed before planting, suggesting that atmospheric precipitate/deposition can move nitrogen from marginal land soils to surface water.","PeriodicalId":35178,"journal":{"name":"WIT Transactions on Ecology and the Environment","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44868937","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several studies have documented the antagonistic relation between traffic-related air pollution (TRAP) and the impact on health, especially to vulnerable members of the population, particularly young pupils. Generally, TRAP could restrict the ability of schoolchildren to learn and, more importantly, cause detrimental respiratory disease in their later life. But little is known about the specific exposure of children commuting to school and during the school day and the impact this may have on their overall exposure to pollution at a crucial time in their development. This project has set out to examine the air quality across primary schools in south east London (due to their massively increasing amount of redevelopment and population) and assesses the variability of data found based on their geographic location and surroundings. Nitrogen dioxide (NO 2 ) and PM contaminants (PM 2.5 and PM 10 ) were collected with diffusion tubes and portable monitoring equipment for eight schools across three local areas: Greenwich, Lewisham and Tower Hamlets. This study first examines the morphological features of the schools surrounding), then utilises two different methods to capture pollutant data. Moreover, comparing the obtained results with existing data from the London Air Quality Network (LAQN) to understand the differences in air quality pre- and post-pandemic. Most studies in this field have unfortunately neglected human exposure to pollutants and calculated referring to values from fixed monitoring stations. This paper introduces an alternative approach by calculating human exposure to air pollution from real-time data obtained when commuting around selected schools (driving routes and field walking).","PeriodicalId":35178,"journal":{"name":"WIT Transactions on Ecology and the Environment","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49501957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
