Abstract:
Biotic and abiotic laboratory experiments of nitrate and nitrite reduction by Fe-containing minerals were performed and the isotopic fractionation of the different reactions was calculated in order to determine whether it is possible to distinguish biotic and abiotic reactions involving N compounds. Results of biotic experiments showed nitrate reduction up to 96 % with transient NO2- accumulation and no significant N2O production. No significant nitrate attenuation was observed in abiotic nitrate reduction experiments. Abiotic experiments of nitrite reduction showed a rapid decrease in nitrite

Abstract:
Iron, Earth’s most abundant redox-active metal, undergoes both abiotic and microbial redox reactions that regulate the formation, transformation, and dissolution of iron minerals. The electron transfer between ferrous iron (Fe(II)) and ferric iron (Fe(III)) is critical for mineral dynamics, pollutant remediation, and global biogeochemical cycling. Bacteria play a significant role, especially in anaerobic Fe(II) oxidation, contributing to Fe(III) mineral formation in oxygen-depleted environments. In iron-rich, neutral anaerobic settings, microbial nitrate-reducing Fe(II) oxidation (NRFO) and ir

Abstract:
A water quality survey of 83 hog farms was conducted in four swine-producing regions of Quebec. Samples were collected from the tap in the piggeries. The mineral content of drinking water varied considerably from farm to farm within regions. In general, drinking water was alkaline and nitrate concentrations were below toxic levels. The drinking water alone could supply up to 20% of a gestating sow's mineral requirements. In some cases (3.6 and 23%), sodium and copper requirements would be exceeded.

ABSTRACTMicroorganisms have been observed to oxidize Fe(II) at neutral pH under anoxic and microoxic conditions. While most of the mixotrophic nitrate-reducing Fe(II)-oxidizing bacteria become encrusted with Fe(III)-rich minerals, photoautotrophic and microaerophilic Fe(II) oxidizers avoid cell encrustation. The Fe(II) oxidation mechanisms and the reasons for encrustation remain largely unresolved. Here we used cultivation-based methods and electron microscopy to compare two previously described nitrate-reducing Fe(II) oxidizers (Acidovoraxsp. strain BoFeN1 andPseudogulbenkianiasp. strain 2002

Abstract:
Vegetables, as an important source of vitamins and minerals, are highly recommended in a healthy diet. At the same time, vegetables can contain elevated amounts of nitrates and nitrites, which are the possible nitrosating agents responsible for the formation of carcinogenic nitrosamines. In young children, they can cause methemoglobinemia. Determining the level of nitrates and nitrites, as well as the possible reduction in their concentrations during culinary processing, is especially important for the diet of young children, who are introduced to leafy vegetables during the first year.

The results of studying nitrate mineralization in rodingites of the Bazhenovsk ophiolite complex located on the eastern slope of the Middle Urals are presented. Rodingites are metasomatic rocks of garnet-pyroxene composition that replace gabbroid and diorite dikes that cut across the Bazhenovsk ultramafic massif. Some apogabber and apodiorite rodingites have in turn been altered by hydrothermal fluids, probably generated by an underlying granite intrusion. Chalcocite is the main sulfide mineral in hydrothermally altered rodingites. It forms clusters of irregular shape, up to 1 cm in size. Visu

Abstract:
Under iron (Fe3+)-reducing conditions where aqueous Fe2+ and unreduced solid Fe3+-oxides commonly coexist, soil Fe2+ oxidation has been shown to be coupled with nitrate (NO3-) reduction. One possible secondary reaction is the involvement of NO3- and nitrite (NO2-) with Fe-oxide minerals found in many natural environments. Yet, spectroscopic measurements and kinetic data on reactivity of NO3- and NO2- with Fe-containing oxide minerals such as goethite (a-FeOOH), and magnetite (Fe3O­4) are not found in the literature. The reactivity of goethite and magnetite with NO3- and NO2- was studied over a

In situ bioremediation represents an alternative strategy that uses the ability of local microbial communities to immobilize contaminants and is actively studied for uranium remediation.

Abstract This paper compares the following six different surface preparation methods: (1) abrasive blasting with mineral sands, (2) ultra-high pressure water jetting (UHP WJ) uninhibited, (3) UHP WJ inhibited, (4) UHP WJ with garnet, (5) UHP WJ with sodium bicarbonate, and (6) power tool cleaning with flapper wheel. Six different types of coupons were used for this test. Four different types of actual process equipment coupons and two different types of mill-scaled coupons were used. The following laboratory tests were run on each type of coupon: (1) invisible surface contaminant detection usi

Abstract:
In contemporary agricultural practice, ensuring sufficient bioavailable macronutrients, particularly phosphorus, for plants in phosphorus-deficient soils remains a significant challenge. As a promising alternative, the application of phosphate-calcium-based nanofertilizers (NFs), with or without zinc, emerges as a suitable solution, offering targeted effects through foliar dispersion. However, current knowledge gaps persist regarding the development and colloidal properties of applied NFs and their impact on sunflower (Helianthus annuus L.), a globally significant oilseed crop known for its br

Abstract:
Abstract Corrosion in gas dehydration systems can be attributed to many factors, including chloride intrusion, acid gas absorption, and glycol degradation. Inhibition systems for glycol dehydration systems must incorporate both corrosion inhibition and buffering, utilizing stable, non-scaling, non-depleting additives. Traditional amine treatments are unstable in carbon dioxide containing gas streams; traditional inorganic salt glycol inhibitors are unstable and cause scaling in the presence of intruded mineral salts. The instability of these inhibitors leaves a dehydration system unprotected a

Abstract:
This article presents the results of studying the content of mineral (ammonium ions, nitrites and nitrates) and organic nitrogen compounds in water samples collected from the Dniester river in 2020. In the study are examines the seasonal dynamics of the forms of mineral nitrogen, total nitrogen and the correlation between organic and mineral nitrogen. Limits of ammonium ion concentration in the Dniester river varied between 0.002 mg N/l and 0.93 mg N/l, nitrite ions 0.002 mg N/l and 0.05 mg N/l, nitrate ions 0.002 mg N/l - 1.36 mg N/l.

In the study are examines the spatial dynamics of the forms of mineral nitrogen, total nitrogen and the correlation between organic and mineral nitrogen. The content of nitrates, nitrites and ammonium ions was determined by the spectrophotometric method to the spectrophotometer UV-VIS Specord 210 Plus. The pH, temperature, have also been determined to asses the chemical status and pollution levels of these water sources

In this article the results on the content of mineral nitrogen compounds (ammonium ions, nitrites and nitrates) during 2020 year in the Prut River Braniște – Giurgiulesti sector are presented. In the study is examinated the seasonal dynamics of these parameters in the winter – spring – summer – autumn period. The range of ammonium ions in the waters of the Prut River varies from 0.002 to 0.26 mgN /L, of nitrite – from 0.002 to 0.02 mgN /L and of nitrates – from 0.002 to 0.73 mgN /L, the maximums being lower than in 2009-2010, and much lower than in the 80s-90s of the last century.

The North central province plays the main agricultural role in Sri Lanka as a developing agricultural-based economy country in the world. Excessive amount of nitrate and fluoride in groundwater consumption is becoming a crucial issue on human health in Sri Lanka, especially in the North Central part of the country. Dental fluorosis and skeleton fluorosis are the major health impacts based on an excessive amount of fluoride as well as presumption on causing chronic kidney disease (CKD). Nitrogenous compounds in groundwater for drinking have been considered possible risk factors for oesophageal
