“…The lower values of COD and BOD5 in the surface water relative to its values in the leachates indicates higher values of dissolved oxygen in the river relative to the leachates samples from the dumpsites. Present findings revealed that the leachates may be potential source of adjacent water sources contamination, also previous findings documented that the leachates are one of the main sources of river water contamination (Ayandiran et al, 2018;Camaño Silvestrini et al, 2019;Deng et al, 2019;Hobson et al, 2018;Kang et al, 2019;Kayembe et al, 2018;Mor et al, 2018;Qu et al, 2019;Rai et al, 2019;Rezapour et al, 2018;Scandelai et al, 2018;Tanikawa et al, 2018;Wu et al, 2018;Xiong et al, 2018;Xu et al, 2018;Yuan et al, 2019;Zhao et al, 2018).…”

The physicochemical characteristics and heavy metal levels of leachates at the Rumuodumaya dumpsites and the surface water of its adjacent river was investigated by appropriate field instrument for in situ measurement, standard procedures and AGILENT 55B spectra for the heavy metals. The results from the dumpsites and surface water of the river generally indicate that as of the time of analysis, there is no serious threat to its immediate environment except the nickel concentrations in the dumpsites and surface water of the river, respectively and whose values were beyond the recommended limit of WHO/USEPA (0.05 mg/L) for safe drinking water. The trend of the results also indicates that the dumpsites are sources of numerous soil and water pollutants capable of depleting oxygen levels in the river and this could pose several and serious health risk to humans and aquatic life. Adequate solid waste disposal technique should be adopted by the appropriate agency to forestall this threat to the Rumuodumaya environment.

“…Figure 2f shows the leachates' TDS levels in the two sites compared to the regulatory body maximum limit. Results revealed that the leachates in Elelenwo dumpsites, Rivers State, Nigeria are polluted, and under the current scenario of increasing water sheds pollution (Abbas et al, 2018;Ali et al, 2019;Barbosa Segundo et al, 2019;Camaño Silvestrini et al, 2019;Čelić et al, 2019;Chu et al, 2019;Costa et al, 2019;Fiorentino et al, 2019;Iqbal, 2016;Iqbal et al, 2019;Joshi and Gogate, 2019;Li et al, 2019;Ma et al, 2019;Majdinasab and Yuan, 2019;Nzediegwu et al, 2019;Poblete et al, 2019;Qi et al, 2019;Wang et al, 2019a;Wang et al, 2019b;Yang et al, 2019;Zhang et al, 2019), there is need to monitor water bodies' quality regularly and adopt the efficient methods to treat the wastewater www.bosaljournals/chemint/ editorci@bosaljournals.com (Caicedo et al, 2019;Hernández-Chover et al, 2018;Mohammadzadeh Pakdel and Peighambardoust, 2018;Salgot and Folch, 2018;Yu et al, 2019).…”

Toxicological symptoms and leachates quality in Elelenwo Rivers State, Nigeria

The toxicological symptoms prevalent and reported in Elelenwo area were taken into consideration and the leachates quality of its notable dumpsites was investigated for possible links. In situ measurements were made and standard procedures followed for analyses of lead, cadmium and nickel as well as other physicochemical load of the leachates. The results obtained were compared with various guidelines set by some notable regulatory bodies. The outcome showed more than 100 folds toxicity levels above the various benchmarks especially for lead, cadmium and nickel. These dumpsites as a result are environmental hotspots for pollution distribution to nearby surface waters, air and wastewaters bodies as well as the ground water. There is a strong link between reported toxicological symptoms among inhabitants of Elelenwo and Leachates toxicity from these dumpsites and there is emergency need for clean-up action by appropriate authorities.

The review aims to report the state-of-the-art constructed wetlands (CW) in the Latin America and Caribbean (LAC) region not limited to national and local conditions. The aim is with a broader view, to bring updated and sufficient information, to facilitate the use of the CW technology in the different countries of LAC. Thus, 520 experiences extracted from the 169 reviewed documents in 20 countries were analyzed. According to the data, horizontal subsurface flow wetlands are the most reported CW in the region (62%), the second most common CW technology in the region is free water surface CW (17%), then vertical flow systems (9%), followed by intensified constructed wetlands (8%), and finally French systems (4%). The performance for nutrient removal is analyzed, finding that the mean of Chemical Oxygen Demand (COD), Total Nitrogen (TN), and Total Phosphorous (TP) removal efficiencies varies from 65% to 83%, 55% to 72%, and 30% to 84%, respectively. The results suggest a generally good performance for COD and TN removal, but a low performance for TP removal. Regarding plant species used for CWs, 114 different plant species were reported, being until now the most extensive report about plant species used in CWs in the LAC region.
