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 ...
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 ...
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 ...
Occurrence of pharmaceuticals, hazard assessment and ecotoxicological evaluation of wastewater treatment plants in Costa Rica
(2020)
The continuous release of pharmaceuticals from WWTP effluents to freshwater is a matter of concern, due to their potential effects on non-target organisms. The occurrence of pharmaceuticals in WWTPs and their associated ...
Expanding the application scope of on-farm biopurification systems: Effect and removal of oxytetracycline in a biomixture
(2017)
Antibiotic-containing wastewaters produced in agricultural activities may depress the pesticidedegrading capacity of biomixtures contained in biopurification systems. This work aimed to assay the effect of oxytetracycline ...
Removal of carbofuran is not affected by co-application of chlorpyrifos in a coconut fiber/compost based biomixture after aging or pre-exposure
(2016-08)
Las biomezclas constituyen la parte biológicamente activa de los sistemas de biopurificación (BPS), que se utilizan para tratar las aguas residuales que contienen pesticidas. El objetivo de este trabajo fue determinar si ...
