Análisis de la respuesta de la evapotranspiración al desarrollo de condiciones de sequía en la región Chorotega
(2021)Esta investigación propone la implementación de un marco que integra la componente de la vegetación a la visión tradicional basada en temperatura y precipitación para analizar el papel del desarrollo de condiciones secas ... -
Bioaugmentation of pilot-scale slow sand filters can achieve compliant levels for the micropollutant metaldehyde in a real water matrix
(2022)Metaldehyde is a polar, mobile, low molecular weight pesticide that is challenging to remove from drinking water with current adsorption-based micropollutant treatment technologies. Alternative strategies to remove this ... -
Effects of the nitrification inhibitor nitrapyrin and tillage practice on yield-scaled nitrous oxide emission from a maize field in Iran
(2021)Nitrification inhibitors can effectively decrease nitrification rates and nitrous oxide (N2O) emission while increasing crop yield under certain conditions. However, there is no information available on the effects of ... -
Removal of pharmaceuticals and ecotoxicological changes in wastewater using Trametes versicolor: A comparison of fungal stirred tank and trickle-bed bioreactors
(2021)Hospital wastewater is loaded with pharmaceutically active compounds (PhACs), which sometimes end up in the environment unaltered due to the lack of effective and specific treatments. The use of white rot fungi, specifically ... -
Nitrapyrin effectiveness in reducing nitrous oxide emissions decreases at low doses of urea in an Andosol
(2021)In the tropics, frequent nitrogen (N) fertilization of grazing areas can potentially increase nitrous oxide (N2O) emissions. The application of nitrification inhibitors has been reported as an effective management practice ... -
Investigation of pharmaceuticals in a conventional wastewater treatment plant: Removal efficiency, seasonal variation and impact of a nearby hospital
(2021-08)Discharges from the wastewater treatment plants (WWTPs) are among the main sources of contamination to receiving surface water, therefore the quality of treated wastewater needs to be properly monitored. However, not only ... -
Investigation of pesticides and their transformation products in the Júcar River Hydrographical Basin (Spain) by wide-scope high-resolution mass spectrometry screening
(2019)The Water Framework Directive 2000/60/EC implemented by the European Union established as the main objectives to achieve a “good ecological and chemical status” of the surface water and a “good quantitative and chemical ... -
Estrategia de Reactivación Turística para la Cámara de Turismo de Turrialba, Pos Pandemia del COVID-19
(2021)Este estudio presenta el análisis de caso de la propuesta de reactivación del sector Turismo post Covid-19 para el cantón de Turrialba, Costa Rica. Este cantón se caracteriza por su componente multiétnico, presencia de ... -
Ecological risk assessment of pesticides in the Mijares River (eastern Spain) impacted by citrus production using wide-scope screening and target quantitative analysis
(2021-06-15)The widespread use of pesticides, especially in agricultural areas, makes necessary to control their presence in surrounding surface waters. The current study was designed to investigate the occurrence and ecological risks ... -
Pharmaceuticals in farms and surrounding surface water bodies: hazard and ecotoxicity in a swine production area in Costa Rica
(2021)The presence of pharmaceuticals in the environment is known to have multiple origins; livestock activities comprise one scarcely studied source, both globally and specially in Latin-America. This work aims to study the ... -
Using Molecular Methods to Identify and Monitor Xenobiotic-Degrading Genes for Bioremediation
(2021)Environmental pollution is a matter of increasing concern worldwide, for which new and innovative solutions are constantly required. Bioremediation, the transformation of contaminants into less toxic substances using ... -
Simultaneous degradation of pharmaceuticals in fixed and fluidized bed reactors using iron-modified diatomite as heterogeneous Fenton catalyst
(2021)The aim of this study was to evaluate the use of pelletized iron-modified diatomite as heterogeneous Fenton catalyst for the removal of carbamazepine, clindamycin, gemfibrozil, ketoprofen, florfenicol, and sulfamethazine, ... -
Selective-enrichment as a Tool to Obtain Microbial Degrading Consortia for the Remediation of Pesticide Residues
(2021)Inadequate disposal of pesticides during their extensive use in agricultural practices may result in soil, surface, and groundwater pollution. These agrochemicals affect a wide variety of non-target organisms, and their ... -
Multi-residue analysis of pharmaceuticals in water samples by liquid chromatography- mass spectrometry: Quality assessment and application to the risk assessment of urban-influenced surface waters in a metropolitan area of Central America
(2021)The occurrence of pharmaceuticals in surface water has been barely studied in Latin America. This work aimed to i) develop a multi-residue liquid chromatography- triple quadrupole mass spectrometry (LC–MS/MS) method for ... -
Environmental monitoring and risk assessment in a tropical Costa Rican catchment under the influence of melon and watermelon crop pesticides
(2021)A monitoring network was established in streams within a catchment near the Costa Rican Pacific coast (2008–2011) to estimate the impact of pesticides in surface water (84 samples) and sediments (84 samples) in areas under ... -
Nitrification inhibitor nitrapyrin does not affect yiel-scaled nitrous oxide emissions in a tropical grassaland
(2021)Urea is the most common nitrogen (N) fertilizer used in the tropics but it has the risk of high gaseous nitrogen (N) losses. Use of nitrification inhibitor has been suggested as a potential mitigation measure for gaseous ... -
Effects of the nitrification inhibitor nitrapyrin and the plant growth regulator gibberellic acid on yield-scale nitrous oxide emission in maize fields under hot climatic conditions
(2021)Nitrification inhibitors are widely used in agriculture to mitigate nitrous oxide (N2O) emission and increase crop yield. However, no concrete information on their mitigation of N2O emission is available under soil and ... -
