Abstract. While eutrophication is often attributed to contemporary nutrient pollution, there is growing evidence that past practices, like the accumulation of legacy sediment behind historic milldams, are also important. Given their prevalence, there is a critical need to understand how N flows through, and is retained in, legacy sediments to improve predictions and management of N transport from uplands to streams in the context of climatic variability and land-use change. Our goal was to determine how nitrate (NO3−) is cycled through the soil of a legacy-sediment-strewn stream before and aft

ABSTRACTThe effect of long-term mixed-waste contamination, particularly uranium and nitrate, on the microbial community in the terrestrial subsurface was investigated at the field scale at the Oak Ridge Integrated Field Research Challenge (ORIFRC) site in Oak Ridge, TN. The abundance, community composition, and distribution of groundwater microorganisms were examined across the site during two seasonal sampling events. At representative locations, subsurface sediment was also examined from two boreholes, one sampled from the most heavily contaminated area of the site and another from an area w

Abstract. Increased anthropogenic inputs of nitrogen (N) to the biosphere during the last few decades have resulted in increased groundwater and surface water concentrations of N (primarily as nitrate), posing a global problem. Although measures have been implemented to reduce N inputs, they have not always led to decreasing riverine nitrate concentrations and loads. This limited response to the measures can either be caused by the accumulation of organic N in the soils (biogeochemical legacy) – or by long travel times (TTs) of inorganic N to the streams (hydrological legacy). Here, we compare

Abstract. Surface water quality along river corridors can be modulated by hyporheic zones (HZs) that are ubiquitous and biogeochemically active. Watershed management practices often ignore the potentially important role of HZs as a natural reactor. To investigate the effect of hydrological exchange and biogeochemical processes on the fate of nutrients in surface water and HZs, a novel model, SWAT-MRMT-R, was developed coupling the Soil and Water Assessment Tool (SWAT) watershed model and the reaction module from a flow and reactive transport code (PFLOTRAN).

In low concentration tracer experiments, and in higher concentration XAS experiments, pertechnetate was added to samples of biogenic and abiotically synthesized Fe(II)-bearing minerals (bio-magnetite, bio-vivianite, bio-siderite and an abiotically precipitated Fe(II) gel).

Abstract. Anthropogenic nutrient enrichment has caused phosphorus (P) accumulation in many freshwater sediments, raising concerns that internal loading from legacy P may delay the recovery of aquatic ecosystems suffering from eutrophication. Benthic recycling of P strongly depends on the redox regime within surficial sediment. In many shallow environments, redox conditions tend to be highly dynamic as a result of, among others, bioturbation by macrofauna, root activity, sediment resuspension and seasonal variations in bottom-water oxygen (O2) concentrations.

A ocorrência de compostos nitrogenados em água residuária de abatedouro de tilápia acima dos limites legais, tem causado sérios problemas de poluição em corpos d'água receptores. O processo biológico para remoção dessas substâncias comumente encontradas sob a forma de nitrogênio amoniacal, é conhecido como nitrificação. Objetivou-se, com o presente trabalho, estudar o efeito do tempo de reação (TR) e da aeração na eficiência da remoção de nitrogênio amoniacal e na conversão do nitrogênio amoniacal a nitrato, de água residuária de abate de tilápia em um reator em batelada sequencial com biofilm

The occurrence of halogenated organic pollutants in indoor dust can be high due to the presence of textile, electronic devices, furniture, and building materials treated with these chemicals. In this explorative study, we focused on emerging organic pollutants, such as novel brominated flame retardants (nBFRs) and some perfluoroalkyl substances, together with legacy polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (BDEs) in settled dust collected in houses and workplaces such as one office and two electrotechnical and mechanical workshops. The total contribution of the inves

A redução de cloreto (NaCl) e/ou de nitrito de sódio (NaNO2) é uma relevante estratégia a ser implementada pela indústria, considerando os problemas de saúde relacionados ao consumo excessivo de sódio. Substituições parciais desses sais por concentrado proteico de soro de leite (WPC), um subproduto da indústria láctea, é uma alternativa a ser investigada visando manter as propriedades tecnológicas dos produtos. Objetivou-se produzir e avaliar a qualidade físico-química de patê de frango com teores reduzidos destes sais, e adicionados de WPC. Elaboraram-se quatro formulações com concentrações v

During the 1960s, small quantities of radioactive materials were co-disposed with chemical waste at the Little Forest Legacy Site (LFLS, Sydney, Australia). The microbial function and population dynamics in a waste trench during a rainfall event have been previously investigated revealing a broad abundance of candidate and potentially undescribed taxa in this iron-rich, radionuclide-contaminated environment. Applying genome-based metagenomic methods, we recovered 37 refined archaeal MAGs, mainly from undescribed DPANN Archaea lineages without standing in nomenclature and ‘Candidatus Methanoper

A bebida láctea é obtida da mistura de leite e soro de leite, fermentada ou não, e que pode comprometer a saúde do consumidor. Além disto, há risco de serem produzidas com soro contendo nitrato e nitrito devido a utilização de tais conservantes na fabricação de queijos. Portanto, o objetivo do trabalho foi avaliar a qualidade microbiológica e físico-química em quatro marcas de bebidas lácteas UAT comercializadas na cidade de Viçosa (MG).

Introduction. The article is devoted to the analysis of the environmental policy of the EU countries on the regulation of public relations in the field of environmental safety. The article clarifies the legislative definition of environmental safety in Ukraine. It was found that the indicator that comprehensively reflects various aspects of the environment, the sustainability of ecological systems, as well as the effectiveness of state policy in the field of ecology is the index of environmental efficiency. The index of ecological efficiency in the context of the countries of the European Unio
