Caracterización fisicoquímica e isotópica (18O y 2H) de la región norte del aquífero Tempisque, Costa Rica
Ordoñez Olivares, Ariana; Beita Sandí, Wilson (2020)Introduction: Groundwater resources supply 70% of drinking water in Costa Rica. Groundwater is in risk of pollution and overexploitation due to the lack of good management practices. There has been an increase in the number ... -
Effect of bromide on NDMA formation during chloramination of model precursor compounds and natural waters
Beita Sandí, Wilson; Erdem, Cagri Utku; Karanfil, Tanju (Water Research, 2020)In this work, we investigated the effect of bromide ion (Br−) on NDMA formation using model precursor compounds, wastewater effluents and surface waters. Previous studies showed that Br− reacts with chloramines and forms ... -
Release of Nitrosamines and Nitrosamine Precursors from Scrap Tires | Environmental Science & Technology Letters
Beita Sandí, Wilson; Selbes, Meric; Ersan, Mahmut S.; Tanju Karanfil (American Chemical Society, 2021)Materials used during manufacturing of tires can be a source of nitrosamines and/or their precursors. Here, we examined the leaching of nitrosamines and nitrosamine precursors from scrap tires under different test conditions. ... -
Removal of Emerging Pollutants by Fungi
Rodríguez Rodríguez, Carlos E.; Cambronero Heinrichs, Juan Carlos; Beita Sandí, Wilson; Durán Herrera, Esteban (CRC Press, 2019)Antibiotics comprise a wide group of emerging pollutants. The growing concern about the presence of antibiotics in the environment is related to their potential of polluting both the aquatic and soil environments; nonetheless, ... -
Removal of N-nitrosodimethylamine precursors by cation exchange resin: The effects of pH and calcium
Beita Sandí, Wilson; Selbes, Meric; Kim, Daekyun; Karanfil, Tanju (2018-11-01)Cation exchange resins have proved to be efficient in removing precursors of N-nitrosodimethylamine (NDMA). NDMA is a probable human carcinogen with a calculated lifetime cancer risk of 10−6 at 0.7 ng/L in drinking water. ... -
Removal of triazines, triazoles and organophophates in biomixtures and application of a biopurification system for the treatment of laboratory wastewaters - ScienceDirect
Masís-Mora, Mario; Lizano-Fallas, Verónica; Tortella, Gonzalo; Beita Sandí, Wilson; Rodríguez-Rodríguez, Carlos E. (ScienceDirect, 2021)Biopurification systems (BPS) have been barely explored for removing complex mixtures of pesticides. In this study, the potential of a biomixture to remove simultaneously a mixture of herbicides (triazines), fungicides ... -
Validation of a methodology by LC-MS/MS for the determination of triazine, triazole and organophosphate pesticide residues in biopurification systems
Masís Mora, Mario Alberto; Beita Sandí, Wilson; Rodríguez Yáñez, Javier E.; Rodríguez Rodríguez, Carlos E. (2020)Biopurification systems are useful in the management of pesticide residues and provide an option to dispose wastewaters of agricultural origin derived from pesticide application practices. The analysis of pesticide residues ...
