Research ArticleOpen accessIn the abstractOccurrence and Seasonal Variation of Antibiotics in Fez-Morocco Surface WaterOualid Chaib, Btissam Arhoune, Sanae Achour et al.The presence and accumulation of antibiotics in the water environment has become emerging contaminants of concern causing disruption of ecosystems worldwide. We describehere the seasonal variation and the occurrence of antibiotic residues in Fez city surface water (Morocco). During one year between February 2014 and January 2015, 8 surface water samples were collected monthly. Quantification of the 7 antibiotics was … …American Journal of Environmental Sciences, Vol. 15, Issue 4 · 27 Aug 2019 · 9,182 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntimicrobial Susceptibility of Bovine Subclinical Mastitis and During Milk Separation Isolates and the Accompanying Hygienic PracticesSultan Farag Nagati, Safaa Khamis HassanMilk is considered one of the most perfect foods for humans and milk contains many nutrients. Subclinical mastitis has been counted as a great problem for dairy manufacture. The disease causes severe economic losses due to lower milk production, treatment costs and increased labor and milk retained for human consumption after treatment and premature culling. A cross-sectional study was conducted … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 2 · 7 Apr 2021 · 6,506 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhytoremediation and Adsorption of Heavy Industry Emitted from Cement Industry through Plant Leaves, Case Study: Golestan Peivand Cement FactorySoleyman Ghorbanzadeh, Meysam Madadi, Sara Abdollahi, Kaveh Ostad-Ali-AskariCement factories are found to be one of the major causes of pollution. Cement mist and dusts depositions affect the photosynthesis, secretion and fertility of the plant. Increasing the concentration of airborne dust reduces photosynthetic potential in leaves, closes leaf stomatals and, in general, reduces the growth and fertility of plants. The purpose of this study is to determine the … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 23 Nov 2020 · 6,438 accessesView PDFCite
Review ArticleOpen accessIn the abstractNanoplastics in the Environment and the Effects on the ZebrafishJimmy De León, María del C. Cotto, Francisco MárquezPlastic is one of the most used materials in the world, adopted in almost all activities of human life, but due to the high persistence and durability in the environment, it is causing pollution problems. Through different processes, small particles of polymers are emerging and the effects on the health are still unknown. The Danio rerio (zebrafish) is a model … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 4 · 8 Oct 2019 · 7,695 accessesView PDFCite
Case ReportOpen accessIn the abstractSteady State Groundwater Flow Modeling of an Ex-Landfill Site in Kuala Lumpur, MalaysiaMustapha Atta, Wan Zuhairi Wan Yaacob, Othman Bin JaafarEffective and rational management of groundwater resources require adequate information on the groundwater flow interactions with surface water and chemical species in the flow regime. The hydrologic conditions beneath the unlined ex- landfill site in Jinjang Kuala Lumpur were investigated to understand the groundwater flow and geochemical setting in which contaminants transport in the groundwater may occur in the ex-landfill. … …American Journal of Environmental Sciences, Vol. 11, Issue 5 · 30 Oct 2015 · 8,092 accessesView PDFCite
Research ArticleOpen accessIn the abstractVitamin C Alleviates Chronic Chlorpyrifos Induced Alterations in Serum Lipids and Oxidative Parameters in Male Wistar RatsS. F. Ambali, M. Shittu, J. O. Ayo et al.Problem statement: Although the increase incidence of cardiovascular diseases, obesity and diabetes mellitus has been attributed to changing life style, the role of environmental contaminants is currently being given considerable attention. Pesticides, including Organophosphate (OP) insecticides are one of the most pervasive environmental contaminants that are deliberately released into the environment. Chlorpyrifos (CPF), a widely used OP insecticide has been … …American Journal of Pharmacology and Toxicology, Vol. 6, Issue 4 · 21 Feb 2012 · 7,576 accessesView PDFCite
Research ArticleOpen accessIn the abstractVitamin E Mitigates Chronic Chlorpyrifos-Induced Oxidative Changes in Pituitary Glands and Testes in Wistar RatsM. Shittu, J. O. Ayo, S. F. Ambali et al.Problem statement: The sperm counts of men have declined by about 50% in the last few decades. The contribution of environmental contaminants to this decline cannot be overemphasized. Pesticide is one of the most pervasive environmental chemical contaminants that have been of increased use due to the compelling need to feed the ever-growing world human and animal population and protect … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 19 Nov 2011 · 7,309 accessesView PDFCite
Research ArticleOpen accessIn the abstractSorption of Phenols: Influence of Groundwater pH and of Soil Organic Carbon ContentSilvia Fiore, Maria Chiara ZanettiProblem statement: Physical and chemical properties of soil, groundwater and pollutants deeply influenced the type and the strength of sorption phenomena involving hydrophobic organic contaminants: Soil fraction of organic carbon (foc) and cation exchange capacity, groundwater pH and pollutants hydrophobicity were with undoubtedly the predominant issues. Approach: In this study an experimental study of the sorption of phenol and 2-nitrophenol … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 7,007 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Assessment of Metals (Pb and Cu) Contamination in Bottom Sediment from South China Sea Coastal Waters, MalaysiaM. C. Ong, B. Y. KamaruzzamanProblem statement: The accumulation of metal contaminants in sediments can pose serious environmental problems to the surrounding areas. Trace metal contamination in sediment could affect the water quality and the bio-assimilation and bioaccumulation of metals in aquatic organisms, resulting in potential long-term implications on human health and ecosystem. Approach: About 154 bottom sediment samples were collected using Smith McIntyre in … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 7,991 accessesView PDFCite
Research ArticleOpen accessIn the abstractFenton Process for the Degradation of Methylene Blue using Different Nanostructured CatalystsMaría del C Cotto-Maldonado, José Duconge, Carmen Morant, Francisco MárquezIn many places of the world, water is a scarcity resource. The possibility of reusing water increases the relevance of developing different water treatment methods. The goal of this research was to determine if the photo-Fenton processes are efficient for the degradation of organic compounds, as a possible alternative for wastewater treatment. In order to carry out this study, different … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 19 Jul 2017 · 8,295 accessesView PDFCite
