“…High level of flood disaster is witnessed along IBB Avenue, Atiku Abubakar, Esuene Street, Urua Ekpa, Nkemba Street among others due to factors such as heavy and prolonged rainfall topography, poor drainage network, dumping of waste in gutters, building along water channels/depression, among others. The resulted in high level of economic hardship, migration and displacement of people from their houses, among others [41][42][43][44][45][46][47].…”

The work examined urban flood intricacies and Implications in Uyo Capital City, Akwa Ibom State, Nigeria with a view to reducing negative flood related scenario that is detrimental to sustainable urban environment. To achieve this, seven flood sites were identified with different depths of drains in the study area. Therefore, flood intricacies are facilitated by natural consequences which further is provoked by anthropogenic parameters such as; road without drains 19.1%, heavy and prolonged rainfall 24.6%, topography 10.2%, dumping of wastes in gutter 13.2%, urban surface characteristics with high cemented surfaces 6%, houses built on watershed 6.2% amongst others. The study pinpoints that flood dynamics is multifaceted with dire consequences on the wholesomeness of Uyo Capital City in terms of loss of lives and properties, disrupted communication routes, and other social impacts. The work recommended that sensitization of residents on human components of flood scenario with appropriate town planning laws must be put in place. Above all, Uyo Capital City must make waste evacuation and management internalized amongst residents for sustainable urban space.

“…Найчастіше розрізняють розчинну, завислу та седиментовану форми металів, стабільність яких значною мірою залежить від інтенсивності перебігу процесів, що відбуваються у водному середовищі та донних відкладеннях того чи іншого водного об'єкта, насамперед гідролізу, комплексоутворення, адсорбції та осадження (Linnik, 2000). Вказані процеси визначають міграційну рухливість важких металів, перерозподіл між основними компонентами водної екосистеми, біодоступність і токсичність для водних організмів (Fufeyin and Egborge, 1998;Linnik et al, 2012;Abdel-Khalek et al, 2016).…”

This article analyses the level of heavy metals (Zn, Mn, Fe, Pb, Co, Ni, Cd) and characteristics of their transportation through the water of minor rivers in Rivne region, Ukraine. The levels of Zn, Cu, Mn, Fe, Ni, Co in the waters of these fisheries exceeded the maximum permissible concentration limit in different months. We found that the concentration of Pb and Cd did not exceed the permissible concentration limit in the waters of the fisheries during the year of research, while the level of other metals exceeded the permissible levels by 1.1 to 151.0 times. This research confirms that the surface waters of Rivne region are characterized by high concentrations of iron, manganese, zinc, and nickel. The level of iron exceeded the maximum permissible concentration limit by 1.1 to 5.0 times, the level of zinc by 1.5 to 15.0 times, that of manganese by1.3 to 6.7 times and the nickel level by 1.3 to 151.0 times in the fishery waters. In principle, the increase in the level of heavy metals (Zn, Cu, Mn, Fe, Ni, Co) is connected with the lithological composition of reservoirs in the water-collecting areas of the investigated rivers, and besides with the significant influence of the anthropogenic load (fuel combustion, aqueous wastes of factory units, agricultural effluent, etc.), and with the increase in aquatic vegetation, pH balance, temperature change and so on. The appearance of iron-manganese compounds can be explained by natural causes such as reformation of the source minerals into secondary minerals in the conditions of pH level recession in water, which causes the release of these molecular entities; leaching of iron from the iron-manganese septarian nodules, a substantial amount of which is contained in the illuvial horizon. The increase in the level of zinc and nickel in the river water is connected with the leaching of these elements from subsurface rocks, soil and forest leaf litter. Atmospheric condensation is a significant source of the presence of nickel in the surface water. For the investigated rivers, the most significant factors in the water's chemical composition are physiographic (foremost, the character of the soil cover, intensivity of erosion, extent of forest and swamp cover) and anthropogenous impact. In the rivers of Rivne region high concentrations of heavy metals are the consequence of the long-term aggradation of abiotic and biotic substances of the water ecosystem. There is a tendency for a reduction in the concentration of most metals in the abiotic substances of the water reservoir during the vegetative season and an increase after the end of this season. This research shows that the high level of contamination of the water of Rivne region's minor rivers by the investigated heavy metal components is caused primarily by anthropogenic factors.

“…Human activities such as mining, melting operations, metal and chemical industries, agriculture, and household activities are the principal sources of heavy metal contamination in the environment (Suciu et al, 2008). Due to their nature, toxicity, and propensity to accumulate in organisms, heavy metals are one of the most harmful categories among the toxic substances (Mortuza & Al-Misned, 2015;Tawari-Fufeyin & Egborge, 1998). Heavy metals accumulate in the living body and affect its normal functions (Budambula & Mwachiro, 2006).…”

Heavy metals are naturally found in the ecosystem, and their presence in the freshwater river is increasing through anthropogenic activities which pose a threat to living beings. In this study, heavy metal concentrations (Zn, Mn, Cu, Cd, Cu, Cr, Pb, and Ni) in different organs (muscle, skin, and gill) of fish from the Padma River were evaluated to quantify, and compare the contamination levels and related human health risks. The results revealed that the heavy metal concentrations in the water, surface sediments, and fish taken from the Padma River were far below the WHO/USEPA's permitted limits. The estimated daily intake (EDI) value in muscle was less than the tolerable daily intake (TDI). The target hazard quotient (THQ) and hazard indexes (HI) were less than 1, showing that consumers face no non-carcinogenic risk (CR). CR values of Cu, Cd, Cr, Pb, and Ni ranged from 4.00 × 10 -8 to 6.35 × 10 -6 , less than 10 -4 , and total carcinogenic risk (CRt) values ranged from 9.85 × 10 -6 to 1.10 × 10 -5 , indicating some pose a CR from consumption of those fish from the Padma River. To establish a more accurate risk assessment, numerous exposure routes, including inhalation and cutaneous exposure, should be explored.
