Research ArticleOpen accessIn the abstractGadolinium at Low Concentration Suppresses both Osteoclastic and Osteoblastic Activities in the Scales of GoldfishNobuo Suzuki, Kazuki Watanabe, Aika Sekimoto et al.For determining the effect of environmental pollutants on fish bone metabolism, we have developed an in vitro bioassay system using teleost scales that has osteoclasts, osteoblasts and bone matrix as markers: alkaline phosphatase (ALP) for osteoblasts and tartrate-resistant acid phosphatase (TRAP) for osteoclasts. Using this bioassay, the influence of gadolinium (Gd) on osteoclasts and osteoblasts of goldfish scales was examined … …American Journal of Environmental Sciences, Vol. 15, Issue 4 · 20 Sep 2019 · 8,451 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Resource Conservation Technology for Adapting Argroecosystems to the New Natural Conditions of a Warming Climate in South-Eastern KazakhstanNaziya Suleimenova, Dastan Kalykov, Baglan Makhamedova et al.This article presents the results of research aimed at developing a resource conservation technology for the adaptation of the soybean agroecosystem to the new natural conditions of a warming climate. In particular, measures to combat drought have been studied: The efficiency of soil-protecting technology (Mini-till) and minimization of anthropogenic impact on soil, the effective use of soil moisture and its … …OnLine Journal of Biological Sciences, Vol. 21, Issue 2 · 25 Jun 2021 · 6,361 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of Heavy Metals on the Enzymatic Activity of Haplic Chernozem under Model Experimental ConditionsNatalia Gromakova, Saglara Mandzhieva, Tatiana Minkina et al.The biological activity of soils is an essential parameter of their ecological status. The anthropogenic Heavy Metals (HMs) disturb the normal functioning of soil biota and, hence, the entire soil system. The aim of this work was to estimate the toxicity of loosely bound HM compounds in Haplic Chernozem using parameters of cellulose-degrading and urease activities. Contamination of Haplic Chernozem … …OnLine Journal of Biological Sciences, Vol. 17, Issue 3 · 23 Jul 2017 · 7,994 accessesView PDF Cite

Research ArticleOpen accessIn the abstractReduction of Microbial Contamination of Outlet Waste in Urban Wastewater Treatment PlantsSona Pazdar, Saeid Eslamian, Hossein Gholami, Kaveh Ostad-Ali-AskariThe available research was managed to monitor the physicochemical and microbiological features of treatment plants. The wastewater treatment herb sewage is a straight pollution input source for anthropogenic pollution. The sediment information ideas to an urban drainage trench as a secondary point pollution source while the organotins information highlights the presence of other spread sources, special to this material. wastewater … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 18 Sep 2019 · 7,607 accessesView PDF Cite

EditorialOpen accessIn the abstractThe Timeless Contribution of Rootstocks towards Successful Horticultural Farming: From Ancient Times to the Climate Change EraIoannis E. PapadakisGrafting is a horticultural practice by which living vegetative plant organs (root, stem and/or buds) of either the same genotype or, usually, different genotypes belonging to the same species, genus, subfamily and/or family, are tightly connected to each other to form a double-compound plant. In fact, it is a method of asexual (clonal-vegetative) propagation of plants. The basal part of … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 4 · 16 Dec 2016 · 9,521 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPREPARATION OF ACTIVATED CARBON FROM PALM OIL SHELL BY CHEMICAL ACTIVATION WITH Na2CO3 AND ZnCl2 AS IMPRENATED AGENTS FOR H2S ADSORPTIONKanokorn HussaroHydrogen Sulfide (H2S, rotten-egg) is one of the major environmental pollutants having its sources in natural and anthropogenic activities. It’s had smell gas produced by anaerobic digestion in acid condition from organic and inorganic compounds containing sulphur, presents dual problems of its toxicity and foul ordour. One of methods of its removal is adsorption. Activated carbon is a widely used … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 17 Jun 2014 · 8,480 accessesView PDF Cite

Research ArticleOpen accessIn the abstractRemediation Technologies for Marine Oil Spills: A Critical Review and Comparative AnalysisD. Dave, A.E. GhalyProblem statement: Anthropogenic activities pollute the oceans with oil through land run off, vessels accidents, periodic tanker discharges and bilge discharges. Oil spills are environmental disasters that impact human, plants and wild life including birds, fish and mammals. Approach: In this study, the International Guidelines for Preventing Oils Spills and Response to Disasters were reviewed and the characteristics of oil … …American Journal of Environmental Sciences, Vol. 7, Issue 5 · 2 Nov 2011 · 25,601 accessesView PDF Cite

Research ArticleOpen accessIn the abstractImpact of Mercury Mine Activities on Water Resources at Azzaba-North-East of AlgeriaFadila Alligui, Abdelhak BoutalebProblem statement: Mercury mineralization occurred in Azzaba (north-eastern Algeria) as a part of mercurial Numidian belt, consists of numerous of Hg deposits (Koudiat Sma, Mrasma, Guenicha, Fendek, Ismail and Ras Elma). These deposits are hosted in a variety of lithologies including sandstone, limestone, breccias and conglomerate. The ores occur as cinnabar deposits in Ypresian-Lutetian formations.

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 PDF Cite

Research ArticleOpen accessIn the abstractMountain Sheep: An Environmental Epidemiological Survey of Variation in Metal Exposure and Physiological Biomarkers Following Mine DevelopmentLawrence K. Duffy, Michael W. Oehler, R. Terry Bowyer, Vernon C. BleichProblem Statement: Anthropogenic activities, such as mining and industrial operations, are a major environmental source of metal exposure for wildlife. Quantitative data regarding biochemical effects of exposure to mineral extraction on mountain sheep, Ovis canadensis, are limited, although their habitats are becoming increasingly affected by expanded resource development. Decisions relating to environmental protection and wildlife conservation should be based on … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 6,654 accessesView PDF Cite
