Abstract: The study investigated the effects of a Telecommunication mast and Tower belonging to Olori Limited on the neighborhoods. The Mast and Tower is geographically located in Mgbede Community, in Ogba/Egbema/Ndoni Local Government Area of Rivers State, Nigeria. The study was necessitated by regular exposure of the victims residing adjacent to the base station to noise and atmospheric pollution emanating from the two generating sets in the area. These cause the victims sleepless nights, headaches, structural damage, rashes and other health challenges resulting to high morbidity and mortality rates among the residents. The study aims therefore to provide a scientific basis on the effects of the mast and Tower located at the area on the environment and health of people living adjacent to the area. With a view of promoting economic prosperity, environmental protection and public health in the area. The method of this study adopted areconvenience sampling of non probability technique and comparative analysis. Bolbakov, Sinitsyn and Tsvetkov describe comparative analysis as a set of analytical techniques which allows making comparisons of different objects and their sets. It gives rise to comparative intellectual analysis which is performed by means of natural intelligence using logical reasoning. Findings from the field observation, comparative analysis of the noise level with regulatory limits as well as review of diverse literatures reveal that the operation of the company in the vicinity is inconsistent with enabling laws that would protect public health, property and environment. As, a result, effective recommendations that would bring lasting peace among the victims and the company have been proposed.

Abstract: Burning of used tyres is a growing activity in urban areas of Côte d'Ivoire. However, this activity is a source of soil pollution. In this context, this study aims to map the sites where used tyres are burned in the city of Abidjan, to describe this practice and to analyse the associated health and environmental risks. Field observations and interviews were conducted with the local population, garage owners and vulcanisers. In addition, the geographical coordinates of the identified tyres burning sites were recorded using GPS. A total of 50 tyres burning sites were identified in Abidjan, including 12 in Yopougon, 10 in Abobo, 05 in Marcory, 06 in Koumassi, 05 in Port-Bouët, 06 in Attécoubé and 06 in Adjamé. Most of the waste tyres burning sites are located close to economic activities, residential areas and rainwater drainage networks, exposing the surrounding population to risks. Tyres burning is carried out exclusively by men. Most of them are aged between 20 and 40 (59%) and most of them have no formal education (77.15%). This activity produces toxic fumes and ash which contain contaminant, posing significant risks to human health and the environment. This study suggests the importance of regulating informal tyres burning due to its proven risks to public health and the environment. The results of this research should guide public policy promoting environmentally sound alternatives for used tyres management, such as recycling and recovery.

Abstract: Potentially toxic metals in aquatic system are produced from natural and anthropogenic sources and the degree of contamination in fish is dependent on the sampling site, pollution types as well as mode of feeding. The concentration of PTMs such as manganese (Mn), iron (Fe), copper (Cu), zinc (Zn), cobalt (Co), chromium (Cr), cadmium (Cd), lead (Pb) and nickel (Ni) were investigated in water, sediment Silver Catfish (Chrysichthys Nigrodigitatus), and Tilapia (Tilapia Zilli) collected from Majidun and Igbede river in Ikorodu using atomic absorption spectrophotometer (AAS). Iron (Fe) was abundant in the entire sample and had the highest level of mean concentration accumulated in the sediment with a value of 0.56mg/L against 0.20mg/L, 0.19mg/L 0.18mg/L recorded in Tilapia, water and Silver Catfish for Majidun river. The distribution of PTMs in the Majidun samples analyzed were in the order of magnitude Fe > Zn =Mn >Cu, Fe > Mn > Zn > Cu > Co >Ni, Fe > Mn > Zn > Cu and Fe > Zn > Mn > Cu for water, sediment, Tilapia and Silver Catfish respectively. The concentrations of PTMs in the samples obtained from Igbede River were found to be significantly higher in the order of Fe > Mn > Zn > Cu, in comparison to the samples obtained from Majidun river, which had an order of Fe > Zn > Mn > Cu, Fe > Mn > Zn > Cu > Co > Ni, Fe > Mn > Zn > Cu and Fe > Zn > Mn > Cu. Ni, Co and Cr were not detected in the analyzed samples except sediment that contain a very low concentration of Ni and Co. The study on the two fish samples from Majidun and Igbede revealed a higher concentration of nickel in the Igbede tilapia fish and sediment. Pb and Cd were not detected in all the samples analysed in the two rivers indicating the pollution status of the two fish species investigated in both rivers. The accumulation of iron and zinc by the fishes from both the surrounding water, sediments and their diet were relatively low and are below recommended value of Food and Agriculture Organization (FAO) and Lagos State Environmental Protection Agency (LASEPA) for daily intake which revealed that the aquatic life analyzed in Majidun and Igbede Rivers are safe for consumption but the need for continuous monitoring to prevent bioaccumulation is recommended.
