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 ...
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 ...
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 ...
Análisis del impacto de fenómenos meteorológicos en Costa Rica, América Central, originados en los mares circundantes
(Centro de Investigaciones Geofísicas 14 (2014): 1-11, 2014-01-19)
Se revisaron en este estudio fuentes de información histórica locales, como los boletines producidos por el Instituto Meteorológico Nacional, para cuantificar los eventos climáticos relevantes y los impactos asociados a ...
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 ...
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 ...
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 ...
Understanding uncertainties in future Colorado River streamflow
(Bulletin of the American Meterorological Society 95(1): 58-81, 2014-01)
The Colorado River is the primary water source for more than 30 million people in the United States and Mexico. Recent studies that project streamflow changes in the Colorado River all project annual declines, but the ...
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, ...
