ABSTRACT
Abstract In this work it was carried out the bioremediation of water containing chlorides with native microalgae (MCA) provided by the Centre for study and research in biotechnology (CIBIOT) at Universidad Pontificia Bolivariana. Microalgae presented an adaptation to the water and so the conditions evaluated reaching a production of CO2 in mg L-1 of 53.0, 26.6, 56.0, 16.0 and 30.0 and chloride removal efficiencies of 16.37, 26.03, 40.04, 25.96 and 20.25% for microalgae1, microalgae2, microalgae3, microalgae4 and microalgae5 respectively. Water bioremediation process was carried out with content of chlorides in fed batch system with an initial concentration of chlorides of 20585 mg L-1 every 2 days. The Manipulated variables were: the flow of MCA3 (10% inoculum) for test one; NPK flow for test two, and flow of flow of MCA3+0.5 g L-1 NPK. Chloride removal efficiencies were 66.88%, 63.41% and 66.98% for test one, two and three respectively, for a total bioprocess time of 55 days.
Resumo Neste trabalho avaliou-se a biorremediação da água com conteúdos de cloretos utilizando microalgas nativas (MCA) fornecidas pelo Centro de Estudos e Pesquisas em Biotecnologia (CIBIOT) da Universidad Pontifícia Bolivariana. As microalgas empregadas apresentaram uma adaptação ao meio de cultura e as condições operacionais avaliadas atingindo uma produção de CO2 em mg L-1 de 53,0, 26,6, 56,0, 16,0 e 30,0 e eficiências de remoção de cloretos de 16,37, 26,03, 40,04, 25,96 e 20,25% para MCA1, MCA2, MCA3, MCA4 e MCA5 respectivamente. A biorremediação da água com conteúdos de cloretos foi realizada em modo batelada alimentada (Feed Batch) com uma concentração inicial de cloretos de 20585 mg L-1. A alimentação foi realizada a cada 2 dias. A variável manipulada foi: ensaio um, uma vazão de MCA3 (10% de inoculo); ensaio dois, uma vazão de NPK e ensaio três, uma vazão de MCA3+0,5 g L-1 NPK. As eficiências de remoção foram 66,88%, 63,41% e 66,98% para os ensaios um, dois e três, respectivamente num tempo do bioprocesso total de 55 dias.

En la Jurisdicción Sanitaria Ecatepec, se realizó un taller de Riesgos y Daños para la salud con el propósito de priorizar el daño a la salud susceptible a ser intervenido a través de la aplicación del método de Hanlón, por los estudiantes de posgrado de Enfermería en salud pública y el equipo multidisciplinario de la jurisdicción. Participaron 48 personas con cargos normativos y operativos de los Centros Municipales de Salud (COMUSA), DIF, CONALEP, y Salud Municipal a quienes se les capacitó sobre la utilidad y aplicación del Método de Hanlón, proporcionándoles la información estadística para hacer los cálculos respectivos. Los resultados de la priorización de mayor a menor puntuación fueron: Diabetes Mellitus tipo 2, Neumonía e Influenza, Enfermedades del corazón, Tumores malignos, Accidentes, agresiones y suicidios, Enfermedades del hígado, SIDA, e insuficiencia renal. Tomando en cuenta que en las primeras cuatro causas ya han sido trabajadas por generaciones previas de estudiantes de la Especialidad, se determinó que la causa a ser intervenida es: accidente, agresiones y suicidios.
In the Health Jurisdiction Ecatepec, a risk and darrage workshop health was carried out which used the Hanlon method in order to prioritize the possible damage and give the attention through the multidisciplinary staff and the Public Health Nursing speciality students. The number of participants in the workshop were 48 from health Municipality Centers, DIF, CONALEP, whom were trained about the features and how to use Hanlon method. The statistical information was given to do the respective calculation. The results of prioritize were ordered from the highest to the lowest score: diabetes mellitus type 2, Pneumania and influenza, heart illness, malign tumors, accidents, agrressions and suicides, liver sickeness, AIDS, renal insufficiency. Because the first 4 causes had been studied before, it was determined that the causes to be intervened will be accidents, agrressions and suicides.
