Research ArticleOpen accessEvery word in the titleThe Contamination Degree of Characteristic Fungi in Jet Fuel Detected by ATP BioluminescenceZezhen Li, Yun Xiong, Bo Chen, ZhenQiao MaAdenosine Triphosphate (ATP) lysate of the characteristic fungi in jet fuel was screened and three fluorescein-luciferase systems were compared in the paper. The correlation between ATP bioluminescence and traditional plate count for measuring the number of microorganism was also investigated and then a method of detecting the contamination degree of the characteristic fungi of jet fuel by ATP bioluminescence were … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 2 · 28 May 2018 · 10,519 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBayesian Network Inference in Binary Logistic Regression: A Case Study of Salmonella sp Bacterial Contamination on Vannamei ShrimpPratnya Paramitha Oktaviana, Kartika FithriasariRecently binary logistic regression has been used to identify four factors or predictor variables that supposedly influence the response variable, which is testing result of Salmonella sp bacterial contamination on vannamei shrimp. Binary logistic regression analysis results that there are two predictor variables which is significantly affect the testing result of Salmonella sp bacterial contamination on vannamei shrimp, those are … …Journal of Mathematics and Statistics, Vol. 13, Issue 4 · 22 Dec 2017 · 7,667 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleContamination Risk Evaluation of Groundwater in the Canton of Portoviejo-Ecuador, using Susceptibility Index and two Intrinsic Vulnerability ModelsSuhail SharadqahThe present study aims to investigate the applicability of DRASTIC, GOD and SI models in evaluating the groundwater vulnerability and risk of contamination in the Canton of Portoviejo, Ecuador. The groundwater vulnerability to contamination has been evaluated using DRASTIC and GOD models. Both models were able to classify the study area into different sectors of variable vulnerability. The coincidence of … …American Journal of Environmental Sciences, Vol. 13, Issue 1 · 11 Feb 2017 · 7,511 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMercury Contamination within Protected Areas in the Brazilian Northern Amazon-Amapá StateRossana Venturieri, Marcelo Oliveira-da-Costa, Cecile Gama, Christoph Bernhard JasterMercury contamination is a long-standing environmental and social problem, notably in the Amazon. The widespread use of mercury in artisanal and small-scale gold mining has driven contamination of the environment and the people, threatening biodiversity, human health and livelihoods of traditional populations. Along the border area between Brazil and French Guiana, illegal gold mining is considered a critical threat to … …American Journal of Environmental Sciences, Vol. 13, Issue 1 · 17 Jan 2017 · 9,246 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Resistance Evaluation of Dry Subtropics Brown Soils to Heavy Metal and Oil Contamination by Biological IndicatorsSergey Ilyich Kolesnikov, Natalya Aleksandrovna Petrova, Kamil Shagidullovich Kazeev et al.Contamination of brown calcareous soils with Cr, Cu, Ni, Pb and oil leads to deterioration of their biological properties. There is a reduction in activity of catalase and dehydrogenase, an abundance of Azotobacter genus bacteria, cellulolytic activity and the length of radish roots. As a rule, there is a direct relationship between the content of contaminant in the soil and … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 3 · 5 Aug 2016 · 7,883 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleContrasting Effects of Metal Contaminations and Soil Liming on Cations Exchange Capacity and Global DNA Methylation in Betula papyrifera Populations from a Mining RegionGabriel Theriault, Kabwe NkongoloThe Greater Sudbury Region in Northern Ontario (Canada) has been one of the most contaminated regions in the world. Soil liming with dolomitic limestone applications has decreased significantly the level of soil acidity resulting in forest regeneration. This reclamation process does not affect the level of soil metal contamination but results in metals availability decrement. The coping mechanisms of birch … …American Journal of Environmental Sciences, Vol. 12, Issue 2 · 11 Apr 2016 · 7,535 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Impact of Chernozem Contamination with Lead and Oil on the Abundance and Composition of MicroarthropodsSergey Ilyich Kolesnikov, Lidiya Sergeevna Samokhvalova, Maria Gennadievna Zharkova et al.Micro arthropods population reduced with increase in the amount of oil in chernozem. The same pattern was observed up to a certain concentration of lead in the soil (background + 250 mg kg-1) and then at high doses (+500 and +1000 mg kg-1) an increase in microarthropods abundance was recorded. Gamazid mites and acaroid-trombidi form complex mites proved to be … …American Journal of Applied Sciences, Vol. 12, Issue 2 · 29 Apr 2015 · 7,598 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHeavy Metal Contamination of Soils and Water Resources Kettara Abandoned MineManuel Valiente, Gustavo Perez, Marta Avila et al.Problem statement: Metal mining; together with mineral smelting and processing, have contaminated the environment surrounding mine areas throughout the world exceeding natural background concentration.

The principal objective of this study was to investigate soil and water contamination in the vicinity of … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 8 May 2012 · 8,831 accessesView PDFCite
Literature ReviewOpen accessEvery word in the titleControl of Contamination of Tissue Plant Cultures During in Vitro Clonal MicropropagationIrina Anikina, Nursultan Kaynidenov, Dora Dayu Rahma Turista et al.Plant micropropagation is currently an important method for modern large-scale propagation of valuable plant crops. Among the risks limiting the success of this method is the contamination of cultured plants. Conventional surface sterilization methods are not always effective against internal infection of plant tissues, and secondary contamination of tissue cultures during replication is also a major problem. This causes scientific … …OnLine Journal of Biological Sciences, Vol. 25, Issue 2 · 8 Apr 2025 · 8,693 accessesView PDFCite
