Biofiltros angostos como medida de mitigación para reducir las pérdidas de nitrógeno desde campos de maíz en la zona central de Chile: balance de nitrógeno durante el primer año
(Universidad de Chile, 2015)
En este estudio se determinó la efectividad de un sistema de biofiltro angosto (ancho de 5m) para retener el nitrógeno (N) que se moviliza hacia cuerpos de agua superficiales desde campos cultivados con maíz grano, comparando la efectividad de...
In this study, the effectiveness of narrow buffer strips (5 m) removing nitrogen (N) that is moving from corn fields to water curses was determined by comparing the effectiveness of different t ype s o f vegetation and establishing an overall N budget in the system during the first year. Five treat ments of different component of the biofilters were evaluated: native trees Luma chequen (GST1) and Drimys winteri (GST2) and a native bush Fuchsia magellanica (GS), this tree in combination with the praire Festuca arundinacea; a treatment with only Festuca arundinacea (G); and a control plot without vegetation (C); with tree replication per treatment with a randomized block design (Blocks 1-3) distributed in 5 m x 12 m plots. Two experimental areas were set in the commune of Pichidegua located in the Región del Libertador Bernardo O'Higgins, both cultivated with maize (Zea mays) as main crop, and in soils with contrasting textures: clay loam in El Caleuche (CLC) (34°25´ S, 71°21´O); and sandy loam in San Luis (SL) (34°22´ S, 71°25´O). During the study period N forms (N-NO3 and N-NH4 ) at the entrance and exit of the biofilter system were continuously monitored. In general, a wide variability of N inputs and outputs was observed, obtaining higher values during the crop growing season (spring-summer). Treatments did not present statistical differences significance (p>0.05) on N retention. In consequence, the biofilters were not effective in removing N forms into surface water bodies using different plant species, which suggest that during the first year of establishment the plant species have not generated an adequate surface coverage and/or root development to retain significant amounts of N forms....

Estudio de adsorción-desorción y degradación de 17-α-etinilestradiol (EE2) en suelos tratados con biosólidos
(Universidad de Chile, 2019)
Actualmente, en varios puntos estratégicos de Chile las aguas servidas son llevadas a plantas de tratamiento donde la fase sólida es separada de la fase líquida para ser tratado simultáneamente con el fin de estabilizarlos y eliminar compuestos...
Currently, at several strategic points in Chile wastewater is taken to treatment plants where the solid phase is separated from the liquid phase to be treated simultaneously in order to stabilize them and eliminate harmful compounds for health. Despite this, some of the organic compounds are not possible to eliminate and remain in these residues or biosolids. Given its high organic content, nutrients and other physical and chemical characteristics, biosolids from treatment plants are used in soils as fertilizer substitutes in order to improve their agricultural quality, where these potential contaminants can pass to plants entering the soil. the trophic chain. Examples of these are pharmaceutical and personal care products (PPCPs), are synthetic organic compounds, which are not found naturally in the environment. They are used in the formulation of antibiotics, anti-inflammatories, antimicrobial agents, synthetic and biogenic hormones, as well as veterinary medicines. Within the PPCPs that enter the wastewater treatment plant, the steroidal hormone 17α-ethinylestradiol (EE2) is found as a source of importance. The environmental risk of this organic contaminant contained in the biosolid applied to the soil depends on the following factors: its concentration, its persistence, its capacity to incorporate itself into the food chain, its lability, and its biotoxicity. According to what is allowed by the current regulations (D.S N ° 004/2009), the soils have the appropriate physicochemical characteristics to be amended with biosolids at a concentration of 90 Mg ha-1. The aim of the present study was to study the adsorption, desorption and degradation of 17-α-Ethinylestradiol in soils treated with and without biosolids. The study of the adsorption and desorption of this compound was evaluated through the determination of equilibrium concentrations in the soil / solution matrix, performing batch experiments, with EE2 solutions in a range of 0.25 - 8.0 mg L-1 in CaCl2 0.01 M. The results showed that desorption rates were given between 13.0 to 28.6% compared to what was adsorbed in the soils, values that decreased in soils amended with biosolids. In a majority way, the models of the adsorption isotherms were adjusted to the Freundlich model, which allowed to obtain Log Koc between 2.97 and 3.79, which shows that the compound tends to adsorb in the hydrophobic part of the organic matter of the soil, which would influence its retention in soils. The EE2 degradation study carried out was carried out at different incubation times, with an enrichment of an EE2 concentration of 10 mgL-1 in the soil and soil/biosolids samples, subjected to a constant temperature and humidity field. The results showed that in all cases the compound degraded between 61.1 to 80.3%, values that increased in soils amended with biosolids...
