Estado del arte en determinación de las variables que definen los modelos de contaminación ambiental en el agua provocado or metales pesados y HAP´s. desarrollo de un metaanálisis.

Abstract:

This work was performed to determine the factors affecting environmental water pollution is caused by heavy metals and polycyclic aromatic hydrocarbons also known by its acronym as PAHs, and provide the scientific basis of MONOIL project. This type of pollution to several factors, including oil as the most constant, either by extraction, accidents, oil spills or wastewater from this same activity. This type of pollution is due to several factors, including oil as the most constant, either by extraction, accidents, oil spills or wastewater from this same activity. To reach this conclusion it was necessary to carry out a meta-analysis, extracting the most relevant variables based on the reading of 182 scientific articles from several countries related to the research topic, which determined when and how to detect contamination in water, its causes, consequences, And the area where pollution generally occurs, resulting in the most contaminated by extraction and wastewater of oil, worldwide, are rivers, followed by the seas. From the obtained variables, including the temperature and PH of the water, it was possible to determine if there was contamination or not, for that the variables were evaluated with a bivariate analysis of logistic regression based on the SPSS statistical software, test version, verifying the results Already mentioned.
