          Abstract

          Resumen Objetivo. Presentar una revisión sistemática de estudios donde se evalúa el impacto provocado por los residuos sólidos urbanos generados en la Mixteca Oaxaqueña. Resultados. El análisis de los resultados de investigación consultados en las bases de datos: Red de Revistas Científicas de América Latina y el Caribe (Redalyc), Scientific Electronic Library Online (Scielo), Dialnet, EBSCO y Consorcio Nacional de Recursos de Información Científica y Tecnológica (CONRICYT), ponen de manifiesto que la contaminación es un problema que se ha venido incrementando a nivel global gradualmente lo que ha derivado que exista presencia de organismos y sustancias extraños que interfieren y dañan la salud de las personas, los recursos naturales y el equilibrio ecológico; cabe mencionar que el impacto en las comunidades provocado por la generación y manejo de los residuos sólidos en forma inadecuada altera de forma importante el ecosistema de los lugares aledaños a los sitios de disposición final de dichos residuos. Es importante hacer notar que existe legislación en la materia y clasifica de forma puntual los diferentes sitios de disposición final y encomienda a los municipios llevar a cabo el manejo integral de los residuos sólidos urbanos pero dicha legislación no es aplicada en forma correcta a pesar de que esta problemática ha tomado mucha relevancia en las últimas dos décadas en los ámbitos gubernamentales. Conclusiones. México tiene el reto de lograr resolver los problemas ambientales para lograr alcanzar un nivel de sustentabilidad y sostenibilidad a mediano plazo, las tasas de generación de residuos sólidos urbanos siguen aumentando por que se vive en una sociedad que ha modificado drásticamente sus hábitos de consumo. La degradación del medio ambiente y los recursos naturales para la región de la Mixteca Oaxaqueña está clasificada en rangos de inestable-crítico a crítico provocando que se ejerza presión sobre los recursos naturales, es por ello que se debe tener una adecuada gestión y disposición de los residuos sólidos urbanos, para lograrlo es preciso contar con el apoyo de la sociedad, gobiernos y sociedad en general, esta sinergia es necesaria para reducir la extracción de recursos empleados al producirlos obteniendo beneficios económicos, sociales y ambientales a largo plazo para la región.

          Abstract Objective. To present a systematic review of studies assessing the impact caused by municipal solid waste generated in the mixtec region of oaxaca. Results. The analysis of the research results consulted in the databases: Red de Revistas Científicas de América Latina y el Caribe (Redalyc), Scientific Electronic Library Online (Scielo), Dialnet, EBSCO and Consorcio Nacional de Recursos de Información Científica y Tecnológica (CONRICYT), show that pollution is a problem that has been increasing at a global level gradually what has resulted in the presence of foreign organisms and substances that interfere with and damage people's health, natural resources and ecological balance; It is worth mentioning that the impact on the communities caused by the generation and management of solid waste in an inadequate manner significantly alters the ecosystem of the places adjacent to the final disposal sites of these wastes. It is important to note that there is legislation on the subject and classifies in a specific way the different final disposal sites and entrusts municipalities to carry out the integral management of urban solid waste but this legislation is not applied correctly despite the fact that this problem has become very relevant in the last two decades in government spheres. Conclusions. Mexico has the challenge of solving environmental problems to achieve a level of sustainability and sustainability in the medium term, the rates of generation of solid urban waste continue to increase because we live in a society that has drastically changed their consumption habits. The degradation of the environment and natural resources for the Mixteca Oaxaqueña region is classified in ranges from unstable-critical to critical, causing pressure to be exerted on the natural resources. This is why it is necessary to have adequate management and disposal of solid urban waste, to achieve this it is necessary to have the support of society, governments and society in general; this synergy is necessary to reduce the extraction of resources used to produce them, obtaining long-term economic, social and environmental benefits for the region.

            Global assessment of exposure to faecal contamination through drinking water based on a systematic review

            Objectives To estimate exposure to faecal contamination through drinking water as indicated by levels of Escherichia coli (E. coli) or thermotolerant coliform (TTC) in water sources. Methods We estimated coverage of different types of drinking water source based on household surveys and censuses using multilevel modelling. Coverage data were combined with water quality studies that assessed E. coli or TTC including those identified by a systematic review (n = 345). Predictive models for the presence and level of contamination of drinking water sources were developed using random effects logistic regression and selected covariates. We assessed sensitivity of estimated exposure to study quality, indicator bacteria and separately considered nationally randomised surveys. Results We estimate that 1.8 billion people globally use a source of drinking water which suffers from faecal contamination, of these 1.1 billion drink water that is of at least ‘moderate’ risk (>10 E. coli or TTC per 100 ml). Data from nationally randomised studies suggest that 10% of improved sources may be ‘high’ risk, containing at least 100 E. coli or TTC per 100 ml. Drinking water is found to be more often contaminated in rural areas (41%, CI: 31%–51%) than in urban areas (12%, CI: 8–18%), and contamination is most prevalent in Africa (53%, CI: 42%–63%) and South-East Asia (35%, CI: 24%–45%). Estimates were not sensitive to the exclusion of low quality studies or restriction to studies reporting E. coli. Conclusions Microbial contamination is widespread and affects all water source types, including piped supplies. Global burden of disease estimates may have substantially understated the disease burden associated with inadequate water services.
