DETERMINATION OF CHEMICAL AND GROSS ORGANIC POLLUTANT LEVELS IN LEACHATES FROM APPROVED WASTE DUMPSITES, PORT HARCOURT METROPOLIS, RIVERS STATE, NIGERIA |  Journal of Global Ecology and Environment

The goal of this study was to determine the amounts of chemical and gross organic pollutants in leachates from a few government-approved dumpsites in the Port Harcourt metropolitan. Using descriptive statistical techniques, leachates from the three dumpsites were examined and compared to seasons, controls, and established criteria. DO, BOD, ORP, salinity, and pH were measured in integrated samples collected throughout both the wet and dry seasons. To explain the trend and variations, 2-way ANOVA, t-test, graphs, and mean variation were used. The findings demonstrate that while there was no significant difference in the temporal dimension (seasonally), there was considerable spatial variance (stations) in most metrics. During the dry season, most chemical and gross organic pollutants had increased concentrations. Despite the fact that some of the indicators were below statutory levels, the study found that these dumpsites continue to be substantial contaminating sources for the surrounding surface and ground water regimes. The state government should ensure the implementation of active remediation techniques and treatment to limit the effects of pollution on the ecosystem in order to rehabilitate these dumpsites from acute contamination.

OIL SPILL INCIDENT MODELLING IN THE COASTAL AREAS OF AKWA IBOM STATE, NIGERIA |  Journal of Global Ecology and Environment

The oil leak episodes in the coastal areas of Nigeria’s Akwa Ibom State were modelled using a Geographical Information System (GIS). Off-shore and on-shore components were included in the model. The oil spill trajectory model was utilised in the off-shore component to follow the course of oil on water flow from the source of the spill to the shoreline and the surrounding environment. The OILSPILLMAP model, which was incorporated into ArcGIS 9 software, was used to input atmospheric, climatic, and petroleum oil parameters. Oil travelled westwards from the simulated source towards the research area’s beaches in Eastern Obolo and Ikot Abasi Local Government Areas, according to the trajectory model. Seasonal fluctuations in ocean currents and other tidal conditions are likely to alter this path of migration. The model’s on-shore component consisted of mapping the study area’s Environmental Sensitivity Index (ESI) based on landuse/landcover. This was utilised to depict the area’s geographical characteristics and, as a result, to forecast the likely impact of an oil spill on the coastal environment. The ESI depicted the vulnerable natural resources at risk, as well as what / where to safeguard in the event of an oil spill. Stakeholders, including host communities, would be tremendously empowered by the integrated GIS-based approach developed in this work to better analyse and monitor oil spill accidents in the operating environments.

INVESTIGATING WATER QUALITY WITH RESPECT TO ALTITUDE OF LAKES AROUND THE NORTHERN ROCKLAND COUNTY IN NEW YORK |  Journal of Global Ecology and Environment

Water is necessary for the life of all living organisms, thus it is critical to safeguard this crucial resource. Water quality refers to the state of water in relation to the needs of one or more biotic species. Experts can assess if water is acceptable for aquatic life or human consumption by looking at its physical, chemical, and biological qualities. The purpose of this study was to look at the relationships between water quality metrics and lake altitudes. ORP, total hardness, pH change, total alkalinity change, dissolved carbonate concentration, and dissolved copper concentration were all used to assess the water quality of ten lakes. The ten lakes were all within a 30-mile radius of each other, and their altitudes were evenly divided. Heavy metals and compounds such as lead, fluoride, iron, mercury, nitrate, nitrite, chromium, bromine, chlorine, and sulphate were undetectable with the kits utilised in this study, according to our findings. On linear regression analysis, the changes in ORP, total hardness, pH, total alkalinity, and dissolved copper concentration had a weak link (R2 0.4352), however the change in carbonate concentration was highly connected with the increase in altitude (R2 0.4352). (R2 0.8814). There could be a subtle association between elements other than water quality, such as the population of people living near water sources.

ANOMALOUS FEATURES OF BLACK CARBON AND PARTICULATE MATTER OBSERVED OVER RURAL STATION DURING OSUN OSOGBO (NIGERIA) FESTIVAL 2015 |  Journal of Global Ecology and Environment

Because to RSPM, it has been observed that death and morbidity rates rise mostly during the Osun-Osogbo period (respirable suspended particulate material). Particles of matter and poisonous chemicals generated during festivals such as Osun-Osogbo, for example, have been researched extensively by several researchers in Nigeria and worldwide. Short-term environmental air quality degradation, poor health impacts, and long-term climatic change are all discussed.

This paper focuses on methods for capturing mass concentrations of various particles, primarily black carbon aerosols, which are some of the most sensitive and representative of fireworks’ negative impact on environmental air quality, dispersion and transport phenomena, potential health effects, and combat processes. The reported results over a typical rural station have been confirmed by in situ satellite data and linked to local meteorological and human activities associated with the Osun-Osogbo festival.

Scientists must be established who can assist in the establishment of safe respiratory levels for human health, taking into account the impact of various pollutants at various damaging levels on human health. It is proposed that preventive steps be taken by prohibiting the use of fireworks during celebrations. These solutions could be considered in the interest of human health and the safety of our planet, resulting in a healthy environment.
