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 ...
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 ...
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 ...
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 ...
Water quality in Costa Rica
(2019)
This book provides an overview of surface and groundwater quality and impacts on human consumption, agriculture and ecosystem services in each country, thereby creating a hemisphere-wide picture of the current status and ...
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 ...
Territorio, Recursos Naturales y Ambiente: hacia una historia comparada : Estudio a través de Argentina, México, Costa Rica, Haití, Paraguay, Uruguay y Venezuela
(Ediciones F.E.P.A.I. (Fundación para el Estudio del Pensamiento Argentino e Iberoamericano), 2014-05)
Nuestro objetivo principal ha sido establecer parámetros para una estudio comparativo de los recursos naturales y el ambiente, en función del territorio, en América Latina, a partir del estudio de casos particulares. Más ...
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 ...
