Controlling COVID-19 Pandemic through Wastewater Monitoring

Djamel Ghernaout, Badia Ghernaout
The continuing global pandemic of coronavirus disease 2019 (COVID-19) produced via severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been a Public Health Emergency of International Concern. Even if the main transmission pathways of SARS-CoV-2 are inhalation from person-to-person and aerosol/droplet transmission, it is proved that the viral ribonucleic acid (RNA) could occur in wastewater, proposing the necessity to better comprehend wastewater as possible sources of epidemiologica...

Water Treatment Challenges towards Viruses Removal

Djamel Ghernaout
In spite of the considerable development registered in microbiology, humankind remains incapable to dominate scientifically and technologically the large microbial world. This is well established and illustrated, unfortunately, in the present Coronavirus disease (COVID-19) pandemic. This work aims to contribute to highlighting the world of pathogenic microorganisms, especially viruses, and their removal from potable water. Identical to the manner by which chemical contaminants are handled in the...

Toxicity of Binary Mixtures of Phenol, Zinc and Cadmium to Yeast Strains Isolated from Hydrocarbon Impacted Soil

O. R. Nlemolisa, C. E. Nwanyanwu, C. O. Akujobi, F. C. Ihenetu, R. C. Nwokorie, C. C. Obasi, U. N. Kemka, K. H. Uzoho, M. C. Nwoke
Toxicity of zinc, cadmium and phenol and their binary mixtures were determined based on inhibition of dehydrogenase activities of yeasts strains isolated from hydrocarbon impacted soil. The yeasts isolated from the hydrocarbon impacted soil were identified as Saprochaete sp. and Cryptococcus sp. The toxicity of chemicals and their mixtures were evaluated in the concentration range of 0 - 16 mM for phenol, 0 - 5 mM for zinc and 0 - 0.4 mM for cadmium. The binary mixture ratios were evaluated. The...

Determination of Radionuclides in Borehole Water in the Adenta Municipality of Greater Accra Region

H. K. Agyeman, T. Glover, B. J. Nyarko, S. Osae, E. O. Darko, F. Adeku, J. K. Amoako, J. Owusu-Banahene, S. Inkoom, B. K. Agyeman, M. Abubakar, P. O. Manteaw, E. Amoatey, O. Gyamfi, D. F. Charles
This study was carried out in the Greater Accra Region of Ghana mainly in the Adenta Municipality to determine the baseline radioactivity levels of naturally occurring radioactive material of water in boreholes using gamma spectrometry. According to WHO, the recommended limit of total committed annual ef-fective dose should be 100 uSv/yr for radioactive materials such as 40K, 226Ra and 232Th, which wil

Advances in the Treatment of Textile Effluents: A Review

Marco Antonio Covi Júnior, Andressa Graciele dos Santos, Elias de Paulo Silva, Guilherme Franqueiro Maimoni, Helísa Naves Martins, Maria Luiza de Moura Assis, Carmen Aparecida Cardoso Maia Camargo, Marcio Antonio Ferreira Camargo
The textile industry moves the economy of several countries, being of great importance for the internal market and also for the external market, but it is considered one of the industries that consume a greater volume of water in its productive process, being one of the largest producers of effluents. Effluents from the textile industries carry toxic, mutagenic and potentially carcinogenic sub

Evaluation on the Concentration of Heavy Metals in Surface Waters in the Municipality of Pratápolis-MG

Daniel Henrique Rattis Lemos, Carmen Aparecida Cardoso Maia Camargo, Marcio Antonio Ferreira Camargo, Maria Diva Landgraf
Mining causes numerous environmental impacts; among them we have to mention the water contamination due to the residues inherent to the activity. “Morro do Níquel”, a mining site, located in southwest Minas Gerais, Brazil, has promoted an increase in the mining activity in the region. There has also been an increase in the amount of residues and substrates produced with the intensification of the mining activity. Being a purificat

Physicochemical and Microbiological Quality of Springs in Kyambogo University Propinquity

Timothy Omara, Winfred Nassazi, Monica Adokorach, Sarah Kagoya
The availability of usable water in an area is the first indication of its demonstrated ability to sustain life. In peri-urban areas, urbanites utilize water from springs and compete disapprovingly for it amongst themselves and with animals. The straggling populace and the compromised sanitation are deteriorating spring water sources. There is an urgent need to analyze springs to ascertain their bacteriological and physical qualit

Evaluation of Concentrations of Heavy Metals in Water Used in Agricultural Irrigation

Marcio Antonio Ferreira Camargo, Thaiany Aparecida Ribeiro Pereira
The knowledge about toxic levels of toxic heavy metals in irrigation water is very scarce and quite varied. This work aimed to evaluate the concentrations of toxic heavy metals in the lake of the Experimental Farm UEMG, Passos-MG Unit. The toxic heavy metals evaluated were Cadmium (Cd), Chromium (Cr) and Lead (Pb). The lagoon was divided into ten strategic points for sampling, each point being sampled in triplicate. The pH of the

Polyurethane Foams Derived from Vegetable Oil Used in the Adsorption of Polychlorinated Biphenyls Present in Insulating Mineral Oil

Marcio Antonio Ferreira Camargo, Antonia Marli dos Santos, Gilberto Orivaldo Chierice, Salvador Claro Neto, Maria Diva Landgraf
PCBs, polychlorinated biphenyls (polychlorinated biphenyls), are the generic names given to the class of organochlorine compounds resulting from the reaction of the biphenyl group with anhydrous chlorine in the presence of a catalyst. They are toxic, persistent, bioaccumulative and pose the risk of causing harm to human health and the environment. Large quantities of PCBs were produced in several countries between 1927 and 1977. I
