    Since the implementation of the Organic Code of Territorial Organization Autonomy and Decentralization (COOTAD) in Ecuador, the local governments have acquired new mechanisms for resource management, now a day the central government assigns a determined budget for each of the local administrations to manage, this capital must be invested in local projects and public works. In the Autonomous Decentralized Provincial Government (GADP) of Chimborazo there are two mechanisms for budget allocation processes, participatory budgets and budgets of direct assignment. Currently in Chimborazo both mechanisms are functioning. This research aims to determine which of the two processes is the most beneficial for citizens. To accomplish these three indicators will be analyzed in each of the mechanisms for budget allocation: efficient spending of resources, number of completed projects and levels of citizen involvement. The data presented for analysis was collected from databases from the GADP of Chimborazo and interviews with key players in each of the processes. Based on this comparative study it is planned to test the hypothesis, which states that the mechanism of participatory budgeting is more efficient, it runs more projects and has higher levels of public participation than direct assignment strategy.Desde la implementación del Código Orgánico de Organización Territorial Autonomía y Descentralización en el Ecuador, los gobiernos seccionales han adquirido nuevas competencias para el manejo de recursos, hoy en día el gobierno central destina un presupuesto especial para cada provincia, el mismo que tiene que ser utilizado en obras y proyectos. En el Gobierno Autónomo Descentralizado Provincial (GADP) de Chimborazo existen dos mecanismos de procesos de asignación presupuestaria, los presupuestos participativos y la asignación directa. Actualmente en Chimborazo los dos mecanismos están vigentes. Este trabajo investigativo busca determinar cuál de estos procesos es el más beneficioso para la ciudadanía. Para este efecto se analizarán tres indicadores en cada uno de los mecanismos de asignación presupuestaria: eficiencia en el gasto de recursos, número de proyectos ejecutados y niveles de participación ciudadana. Los datos presentados en este estudio provienen de bases de datos del GADP de Chimborazo y de entrevistas realizadas a actores claves en cada uno de los procesos. En base a este estudio comparativo se busca comprobar la hipótesis que sostiene que el mecanismo de presupuestos participativos es más eficiente, ejecuta más proyectos y tiene mayores niveles de participación ciudadana que la asignación directa

    Identification of bisphenols and derivatives in greenhouse dust as a potential source for human occupational exposure

    Bisphenol A (BPA) and alternative bisphenols are widely used in the industrial production of polycarbonates and resin polymers. Adverse effects on human health have been described for BPA and owing to the structural similarity of alternative bisphenols and derivatives, a similar toxicity profile is expectable. Dust can act as a sink for bisphenols owing to the large surface area to mass ratio. Human risk exposure to bisphenols via indoor dust has been widely assessed in the last decade. The environmental conditions inside greenhouses, among other factors, facilitate that chemicals are released from greenhouse building materials to dust. This study aims to explore for the first time the potential of greenhouse dust as a new source of bisphenols for human exposure. For this purpose, a supramolecular solvent-based method was applied to the extraction of twenty-one bisphenols from greenhouse dust, prior to their determination by liquid chromatography–tandem mass spectrometry. Nineteen bisphenols were found in the five greenhouse dust samples analysed, with concentrations ranging from 5275 ng g(−1) (BPA) to 0.25 ng g(−1) (trichlorobisphenol A). The average daily dose (ADD) via dust ingestion for bisphenol compounds was calculated, in order to estimate the occupational exposure for inadvertent dust ingestion. Despite the calculated ADD value for BPA (47.81 ng kg(−1) day(−1)) being below the tolerable daily intake proposed by EFSA (4·10(3) ng kg(−1) day(−1)), this value was considerably higher than those previously reported for indoor dust, which brings to light the importance of considering greenhouse dust as bisphenols source of exposure for greenhouse workers.
