17β-estradiol (E2), ampicilina (AMP), así como los colorantes sintéticos Rojo 40 y Amarillo 5, se han incluido en el grupo de contaminantes emergentes (CEs). Estos generan diferentes problemas ambientales disrupción endocrina biota acuática a concentraciones traza. Debido su compleja estructura son difíciles degradar por tratamientos convencionales. Los procesos oxidación avanzada (POA) tipo Fenton mostrado resultados prometedores la compuestos orgánicos tiempos cortos reacción. En este...
Soils are the most important terrestrial carbon (C) sinks in biosphere. They play a crucial role regulating global cycle, and key to provision of ecosystem services. Soil sequestration accumulation is useful means reduce atmospheric CO 2 concentration mitigate climate change. A study was conducted El Chico National Park, Hidalgo, Mexico, with objective evaluating soil fractions under different vegetation types. Five sampling zones (fir forest, fir-tlaxcal, cedar, fir-oak, pine-oak) were...
A challenge for the oil refinement industry is production of high-octane gasoline with a low benzene content. This work reports calculation atmospheric emissions generated from storage, transfer, and transport operations in Mexico, estimating 1.48 KBPD environmental release. The aim was to estimate minimum through operative improvements refineries, initially by performing simulations Naphtha Catalytic Reforming (NCR) process using ASPEN HYSYS® ver. 8.8 (34.0.08909) then optimizing conditions...
A high amount of nutrients can be found in urban wastewater (UW), which makes it difficult to treat. The purpose this research was evaluate the potential aquatic macrophytes Eichhornia crassipes, Pistia stratiotes, and Salvinia molesta treatment UW. To each macrophyte, phytoremediation bioassays were established; hydraulic retention time for bioassay 15 days. physicochemical analysis water samples considered pH, turbidity, electrical conductivity (EC), total dissolved solids (TDS), oxygen...
Todos los productos que se utilizan en la vida cotidiana, son resultado de un proceso químico industria donde desarrollaron, misma requiere grandes cantidades energía, cual es generada por combustión diferentes combustibles a su vez liberan atmósfera concentraciones Gases Efecto Invernadero (GEI). En este ensayo presentan ejemplos y argumentos cómo transformación materia tiene impacto negativo al medio ambiente salud humana. Las emisiones GEI atmosfera, cada día más preocupante ya originan...
Perchlorate is a contaminant and endocrine disruptor present in vegetables. To address the lack of information on this problem Mexico, we developed an analytical method to quantify perchlorate commonly consumed vegetables based quick polar pesticide (QuPPe) extraction ultra-performance liquid chromatography coupled tandem mass spectrometry (UPLC-MS/MS). The was validated through parameters selectivity, accuracy, precision, linearity, limit detection (LOD), quantification (LOQ) according...
Oil refining industry have as a challenge the high-octane gasoline production and its reformulation with low benzene content. This work reports mass balance of emissions from vessel transfers transport operations in Mexico, an estimated total maximum flowrate 1.48 KBPD, considering evaporative losses. The aim this is to provide operative proposal for minimizing by developing ASPEN HYSYS ® simulation study Naphtha Catalytic Reforming (NCR) process Continuous Catalyst Regeneration (CCR) mode...
17β-estradiol (E2) is the natural estrogen with most significant potential for endocrine disruption in biota of aquatic ecosystems at trace concentrations. It is, therefore, essential to study treatments water polluted E2 that would guarantee its complete elimination and mineralization. Denitrification a biological process shown have capacity completely biodegrade drugs, such as ampicillin. This work aimed evaluate biotransformation by employing denitrifying sludge. The assays performed...
The denitrification process has been studied for biodegradation of some emerging contaminants (ECs). For this, anaerobic sludges from different Wastewater Treatment Plants (WTP) have used; however, the capacity can differ due to contact they had with various pollutants, given their origin. This work aims evaluate kinetic and metabolic two denitrifying WTPs biodegrade CH3COO--C NO3--N. Denitrifying tests were carried out in batches (30 mg L-1) a CN-1 relationship 1.8 sludge WTP an educational...
El ozono en la estratósfera forma una capa atmosférica muy importante que ayuda a preservación de vida tierra, ya sin su presencia los rayos UV-C llegarían directamente población, generando diferentes problemas salud seres vivos. La literatura menciona ha entrado fase deterioro causa compuestos derivados hidrocarburos saturados como clorofluorocarbonos (CFC´s). Debido creciente preocupación comunidad científica, se han incrementado estudios con finalidad comprender el comportamiento o tiene...
