Revista internacional de contaminación ambiental , 2003,
Abstract: En el presente trabajo se realizó el inventario de las fuentes de contaminación en 14 municipios del estado de Hidalgo, México. Es importante determinar cualitativa y cuantitativamente las emisiones contaminantes en esta parte del estado que concentra alrededor de 40 % de la población, las principales vías de comunicación, los servicios y parques industriales. La metodología empleada está basada en la técnica de evaluación rápida de fuentes de contaminación ambiental. Esta técnica permite evaluar de manera rápida y económica las principales fuentes y zonas de contaminación; se utilizaron coeficientes y cálculos de aportes contaminantes basados en datos de producción industrial e información estadística. Se determinó el número de fuentes contaminadoras, su naturaleza y la cantidad de las emisiones a suelo, agua y aire en el área de estudio. Los resultados se agrupan de acuerdo con la clase de fuentes de contaminación por municipio, sector generador y tipo de contaminantes, esto permite la jerarquización de la problemática ambiental de Hidalgo y proporciona elementos para formular políticas de combate y prevención de la contaminación al ambiente en esta entidad.

Abstract: El estado de Hidalgo, México presenta una importante problemática ambiental que se manifiesta de manera heterogénea a lo largo de su territorio. Existe la necesidad de conocer las fuentes, tipos de agentes contaminantes y su magnitud. En este trabajo se realizó un inventario de la contaminación emitida por fuentes de origen industrial y doméstico en aire, agua y suelo en diez municipios de la región de la Huasteca por medio de la técnica de Evaluación Rápida de Fuentes de Contaminación Ambiental (ERFCA). El total de la contaminación emitida fue de 116 978.95 ton/a o. Las emisiones al aire por vehículos a gasolina fueron un total de 11 039 ton/a o, los vehículos a diesel emitieron 1521 ton/a o. Para agua, las fuentes industriales aportaron 22 496 ton/a o, las domésticas 15 776 ton/a o. La contaminación emitida al suelo por residuos sólidos industriales fue de 4025 ton/a o, los residuos sólidos urbanos emitieron 62 121 ton/a o. Por municipio, Huejutla de Reyes fue el más contaminado en aire, agua y suelo con 53 % del total. A partir de estos resultados fue evaluada la calidad ambiental de cada medio, que con base en la normatividad mexicana, no es admisible para agua y suelo. Se construyó una base de datos con información relevante que apoyará el manejo eficiente de las emisiones contaminantes, la realización de estudios complementarios y promoverá la futura conservación de la calidad ambiental y la riqueza biológica de la zona.

Journal of Environmental Protection (JEP) , 2014, DOI: 10.4236/jep.2014.512120
Abstract: Waste electrical and electronic equipment (WEEE) has brought negative effects to the environment produced by the materials that compose them. The proper implementation of management plans of WEEE should integrate measures to prevent, mitigate and correct these affectations. As an initial step, it is necessary to make a diagnosis of the current situation of WEEE management which is the objective of this work. The studied zone was composed by the municipalities of Tampico, Ciudad Madero and Altamira located in southeast Tamaulipas, Mexico. The descriptive analysis of technical and regulatory aspects of the current management system in the study area was developed, including generation rates and analysis of waste streams. Among the main results, the generation of WEEE was estimated in 2040.38 tons/year for 2013, distributed in the municipalities of Tampico with 830.93 tons/year, Altamira with 650.18 tons/year, and Ciudad Madero with 559.27 tons/year. This calculation was estimated using Mexico’s WEEE generation indicators. The analysis of waste streams includes five categories of WEEE, Televisions with 61% of the total generation, followed by sound devices with 18%, personal computers with 17%; mobile phones with 2% as well as fixed phones with 1%. In the study area, reports of Tampico’s municipality indicated that 96 tons of WEEE was collected in the city of Tampico in 2013. In México, the national legislation considers WEEE in the category of waste requiring special handling (WRSH), however, it exists an inadequacy in the environmental laws about the specific classification of this kind of debris that makes their effective management more difficult. No companies who provide a management or treatment operations for WEEE are reported in Tampico, or in the near region. In addition, despite an initial interest for the municipality to attend the WEEE problematic, it exists a lack of sensibility of the population in the absence of environmental education programs.

Abstract: Modelar la calidad del agua del río Tula, desde el emisor central hasta su confluencia con la presa Endhó, ha sido el objetivo central de este trabajo. Se evaluó durante dos a os, considerando una longitud de 50 km en 4 zonas y 35 sitios de muestreo. La mayor cantidad de materia orgánica la aporta el emisor central, agua sin tratamiento de la Ciudad de México y zona conurbana. Los valores de DBO variaron desde 1.16 hasta 486.81 mg O2/L; el oxígeno disuelto entre 1.52 y 5.82 mg/L, esto implica afectación para el desarrollo de la vida acuática. La alcalinidad rebasó el criterio ecológico de calidad como fuente de agua potable con valor de 458.01 mg/L. Las grasas presentaron variaciones desde 0.9 mg/L hasta 18.1 mg/L y el nitrógeno amoniacal fuera de los límites establecidos para protección de la vida acuática con valores desde 0.09 a 64 mg/L; los nitratos (6.24 mg/L) y nitritos (0.5-1.304 mg/L) rebasan el criterio ecológico. Los metales cadmio, plomo, hierro, manganeso y zinc están en concentraciones por encima de lo permisible en y en algunos tramos se reportó presencia de mercurio. Los coniformes fecales fueron detectados en valores desde 2.1 x104 hasta 2.40 x1011 NMP/100 ml. En general la toxicidad en las descargas de aguas residuales demostró que todas se presentan de moderada a alta. Solamente tres estaciones de monitoreo (19 %) con excelente calidad, DBO5 menores o iguales a 3 mg/L, lo que se considera como agua no contaminada por materia orgánica biodegradable.

Abstract: the biosolids originated in the treatment of municipal wastewater are used in agricultural soils as a source of nutrients and organic matter. heavy metal content may restrict their use as agricultural amendment, due to the potential risk of introducing them into food webs. to determine the total concentration of heavy metals in soils amended with biosolids is an insufficient criterion for assessing this risk. heavy metals are bound to different solids components of soil, which according to their different physicochemical characteristics have different availability. the aim of this study was to determine distribution and bioavailable concentrations of cd, cu, ni, pb, and zn in soil amended with biosolids in a period of six years and a possible relationship between the bioavailability and distribution of metals with the age of application. it was used a sequential chemical extraction procedure of four steps for determining the concentrations of cd, cu, ni, pb, and zn in four operationally defined chemical fractions that represent the bioavailability and distribution of metals in the amended soils. the total concentrations were determined by an open system acid digestion. the quantification of heavy metals was performed by icp-aes. the cd was not detected. the bioavailability of cu and pb decreases with age of application and zn increases. the age of application of biosolids influenced the redistribution of cu, pb, and zn in the four extracted fractions. the distribution of ni is less affected by the age of application of biosolids. the metals studied are held in a high percentage in the more stable fractions, oxidizable and residual. the bioavailable fraction of each metal shows low percentages, indicating low availability in the soil and therefore a low risk of being incorporated into food webs.

Abstract: in the last years, mathematical modeling has been used to try to represent the chemical changes that occur in the environment. traditionally the models are based on the mass balance and the kinetic chemistry of the bioprocesses. in this study the equations obtained for a biological isothermal reactor type shaken tank are applied and simulated by using adimensional linear equations in quasi-stationary state. in order to give validity to the results derived from the analytical solution, these are compared with the results experimentally obtained at laboratory level for a methanogenic digester in a mesophyll regime of temperature, used for treating residual effluents from the distillery industry under different operational conditions, using as microbial partnership bovine rumen fluid. the results of the model agree with the production of biogas and the reduction of organic charge (expressed like cod), having an average factor of adjustment for both cases of r2=0.9960 and a variation of 0.01601, when a kinetic reaction of first order is proposed, and using free cells in the environment. in addition this model is able to predict when the system reaches the stationary state.
