Environmental monitoring and risk assessment in a tropical Costa Rican catchment under the influence of melon and watermelon crop pesticides
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 ...
Simultaneous degradation of pharmaceuticals in fixed and fluidized bed reactors using iron-modified diatomite as heterogeneous Fenton catalyst
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, ...
Pharmaceuticals in farms and surrounding surface water bodies: hazard and ecotoxicity in a swine production area in Costa Rica
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 ...
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
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 ...
Removal of pharmaceuticals and ecotoxicological changes in wastewater using Trametes versicolor: A comparison of fungal stirred tank and trickle-bed bioreactors
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 ...
