Resumen

Climate change and environmental disasters are strongly dependent. Humanity is facing considerable changes in environmental adaptions and remediation of contaminated sites. Water is a valuable resource that should be protected and prevented from hazardous influences. One of the main water quality problems is the excess of nutrients causing algae blooming. Many surface-and groundwaters have lost the ability to be used as anthropogenic water sources and other purposes (recreation, water supply, irrigation, etc.). Both nutrients and other substances impact water quality and climate change, making

Resumen

It is estimated that 2.7 billion people worldwide are served by on-site sanitation facilities that require faecal sludge management. Anaerobic digestion is a treatment mechanism that can provide faecal sludge management, methane production and an effluent digestate rich in nutrients. However, there is a paucity of information regarding the composition of the input faecal sludge which hinders the advancement of anaerobic digestion treatment and downstream nutrient recovery together with a lack of knowledge as to how best to recover these output nutrients in a simple process.

Resumen

The main objectives of this dissertation were (a) to determine the effects of nitrogen (N) and phosphorus (P) fertilization on the growth of microalgal groups of periphyton and phytoplankton, and (b) to evaluate some indicators of the regulatory processes (e.g. N:P content, chlorophyll content per biovolume) involved in such growth responses. To do so, we followed a field experimental approach of short-term nutrient enrichments (21-25 days), using nutrient-diffusing substrates in the case of epilithic periphyton (Chapter 1), and mesocosms in the case of phytoplankton (Chapter 2 and 3).

Three novel methods were examined to assess the effects of nutrient enrichment in three sub-tropical east Australian estuaries with differing levels of catchment disturbance. The Manning and Wallamba River catchments are 8927 and 500 km2 respectively and support intensive livestock agriculture and some residential development, whereas the smaller Wallingat River catchment is 185 km2 and is mostly forested. The Wallamba and Wallingat Rivers flow into Wallis Lake, which was the site of an environmental crisis in 1997 when the consumption of sewage-contaminated locally grown oysters caused an out

Increased inputs of nutrients to estuaries and coastal waters can cause undesirable effects associated with eutrophication, including nuisance and toxic algal blooms, reduced amenity value, changes in species composition, bottom anoxia and fish kills. The main sources of nutrients to estuaries are river runoff, sewage discharges, atmospheric inputs and possibly submarine groundwater discharges. For the UK, estuarine eutrophication has been shown to occur in at least 16 estuaries (including the Taw in North Devon).

Resumen

Understanding the dynamics of leaf litter inputs in streams involves assessment of retention, spatial distribution and processing of leaf litter inputs. However, leaf litter dynamics in streams has been mostly studied by determining the controlling factors of leaf litter processing, ignoring if leaf litter inputs are retained within the streams, and how these inputs are spatially distributed within the streambed. Furthermore, leaf litter processing in streams is not an isolated process because it can be linked with the dynamics of solutes of these streams. In fact, leachates from leaf litter

Banco do Nordeste do Brasil<br>Os biofertilizantes lÃquidos vÃm sendo utilizados com relativo sucesso na recuperaÃÃo de bananais que apresentam baixa produtividade, apÃs longo tempo de cultivo. Essa Ãrea ainda carece de estudos, porque sÃo poucas as informaÃÃes existentes relacionadas a tratos culturais que visem ao aumento da vida Ãtil do bananeiral. O objetivo deste trabalho foi fazer um estudo comparativo em Ãreas de bananais degradados que receberam aplicaÃÃo do biofertilizante por um perÃodo de 2 e 5 anos e Ãrea onde a cultura nÃo recebeu esse tipo de aplicaÃÃo.

Resumen

A presente pesquisa estudou a viabilidade do emprego de sais de magnésio em estações de tratamento de esgoto sanitário visando a remoção do fósforo, bem como a produção de estruvita, mineral que pode ser utilizado diretamente no solo como fertilizante. As estações estudadas nesta pesquisa foram a Estação de Tratamento de Esgoto Sanitário de Franca-SP e a Estação de Tratamento de Esgoto Sanitário Jardim das Flores, localizada no município de Rio Claro-SP, e a Estação de Tratamento de Esgoto Sanitário Piçarrão, no município de Campinas.

Resumen

O feijão-caupi, através da simbiose com bactérias do gênero Bradyrhizobium, pode obter N através do processo de fixação biológica do N2 (FBN), que é uma das formas de incrementar a produtividade de leguminosas, evitando-se custos com adubos nitrogenados solúveis. As deficiências nutricionais podem interferir na FBN, pois o fósforo, deficiente na maioria dos solos tropicais, tem efeito marcante sobre a atividade da nitrogenase. Com isto objetivou-se com este trabalho avaliar as doses de fósforo na cultura do feijão caupi em condições de casa de vegetação e em campo de cultivo com e sem o uso de

Este trabalho teve como objectivo principal avaliar tecnologias que permitam monitorizar o efeito das árvores sobre a dinâmica dos nutrientes no solo e sobre a variabilidade da produtividade e da qualidade de uma pastagem integrada no ecossistema de montado. O processo de amostragem foi realizado entre Novembro de 2015 e Julho de 2016. O estudo revelou um efeito positivo das árvores sobre as propriedades do solo e sobre a qualidade da pastagem.

Resumen

High concentrations of dissolved nutrients in stormwater have been identified as contributing to eutrophication of receiving waterways near urban areas. To reduce dissolved nutrient concentrations in stormwater a range of devices such as wetlands and bioretention systems are used. Bioretention systems are increasingly employed for their supposedly high nutrient removal capacity, however very little is known about their treatment efficiency or the chemical and biological mechanisms controlling their function. This research aimed firstly to test and compare the efficiency of different bioretenti

Resumen

The variability in surf-zone phytoplankton community composition together with variability in nutrient concentrations was studied at seven beaches along the coast near Port Elizabeth, South Africa over a one-year sampling period. The nutrient requirements of selected diatoms and dinoflagellates that co-occur at these beaches were studied. The highest nutrient concentrations were recorded at Brighton beach, with phosphate concentration being substantially higher than standards set out for both South African and European waters. Nitrate, ammonium and silicate concentrations were consistent (low

Resumen

Ovine placental lactogen (oPL) is postulated to be involved in the repartitioning of maternal nutrients during pregnancy, through its effect on insulin metabolism. Ovine pancreatic insulin responses to exogenous glucose are depressed during pregnancy and this depression becomes more pronounced as gestation advances. In addition, under the hormonal environment of rising oPL and growth hormone (oGH) concentrations, maternal whole body glucose irreversible loss (GIL) increases. The percentage of GIL accounted for by uterine glucose uptake also increases with advancing gestation and increasing lit

Resumen

Using nutrients bacteria utilize to grow as treatments of bacterial biofilms have been investigated. This dissertation examines the problem of the prevention and treatment of biofilms by: (i) testing the effect of the nutrient ?-phenylethylamine (PEA) on growth, ATP content of biofilm, and biofilm biomass, (ii) testing the effect of ethyl acetoacetate (EAA) and other small molecules on growth, ATP content of biofilm, and biofilm biomass, and (iii) investigating three applications of PEA and EAA. PEA could be used as both, prevention and treatment for bacterial biofilms. We observed a reduction

A large number of children eat at least one and sometimes two or more of their meals at child care centers.
