Validation of a methodology by LC-MS/MS for the determination of triazine, triazole and organophosphate pesticide residues in biopurification systems
(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 ...
Biodegradation of Pharmaceuticals by Fungi and Metabolites Identification
(2012-01-01)
Pharmaceutical compounds comprise a widely employed group of
therapeutic agents now considered as emerging micropollutants. This chapter
summarizes the state of the art in the degradation of pharmaceuticals by fungi ...
Release of Nitrosamines and Nitrosamine Precursors from Scrap Tires | Environmental Science & Technology Letters
(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. ...
Sorption Parameters of Carbendazim and Iprodione in the Presence of Copper Nanoparticles in Two Different Soils
(Springer, 2019)
Today, metal nanoparticles are being incorporated into soil through several routes, where they could alter the sorption behavior of other contaminants such as pesticides. Therefore, a short assay was carried out through ...
Pesticide dissipation capacity of an organic biomixture used in the agriculture exposed to copper oxychloride
(2020)
Highlights:
• Copper oxychloride addition in a biopurification system was evaluated.
• Simultaneous presence copper and pesticides affected slightly its dissipation capacity.
• Microbial communities and biological ...
Fungal bioaugmentation of two rice husk-based biomixtures for the removal of carbofuran in on-farm biopurification systems
(2016-02)
The ligninolytic fungus Trametes versicolor was employed in the bioaugmentation of compost- (GCS) and
peat-based (GTS) biomixtures for the removal of the insecticide-nematicide carbofuran (CFN). Among several lignocellulosic ...
Impaired pesticide removal and detoxification by biomixtures during the simulated pesticide application cycle of a tropical agricultural system
(2020)
Biopurification systems (BPS) or biobeds have been developed to attenuate point-source contamination due to inappropriate pesticide handling or disposal of agricultural wastewaters. The biomixture used for this strategy ...
Una nueva especie de Adraneothrips (Thysanoptera, Tubulifera, Phlaeothripidae)
(2007-09)
A new species of Adraneothrips (Thysanoptera, Tubulifera, Phlaeothripidae). A new species of Adraneothrips Hood,
1925, soil Thysanoptera, is described from Costa Rica. A key for the recognition of the species of Central ...
Parámetros físico-químicos en aguas costeras de la Isla del Coco, Costa Rica (2001-2007)
Physico-chemical parameters in coastal waters around Isla del Coco, Costa Rica (2001-2007)
(2008-11-17)
Four cruises to Isla del Coco (Cocos Island), Costa Rica, were carried out in order to gather oceanographic data
related to surface temperature, salinity, dissolved oxygen concentration, Secchi disk depth, nutrient ...
Removal of cimetidine, ketoprofen and naproxen by heterogeneous catalytic ozonation over volcanic sand at low pH
(2020)
This work presents experimental results on the catalytic effect of volcanic sand on the simultaneous removal of naproxen, ketoprofen, and cimetidine by ozonation. Catalyst characterization included XRD, EDX, XRF, SEM and ...
